A REVISION OF THE NORTH AMERICAN SPECIES OF THE
BRACONID GENUS HABROBRACON JOHNSON (ASHMEAD .
BY R. A. CUSHMAX, Bureau of En/mi,,,!, ,!/,/.
The name Habrobracon was given by Ashmead in his ( '1,-i
fication of the Ichneumon Flies (1900) to include those members
of the genus Bracon in which the second abscissa of the radiu-
is "not, or scarcely, longer than the first, usually a little shorter
than the first transverse cubitus, or no longer." Previous to this
date, however, W. G. Johnson published a note i Knt. \e\vs, IX'.O.
VI, p. 324-5) in which he used the name in connection with the
s; ecies hebetor Say and gelechice Ashmead. Ashnic:id (loc. cit.,
p. 173) gives as the first publication of the name the above note
by Johnson. This makes it necessary to credit the genus to John-
son. Viereck (Bull. 83. I". S. Nat, Mus., 1914, p. ii.'n credits the
genus to Ashmead and fixes Bracon yelcclt/<r A<hmead as the
type.
The following description of the genus is gleaned from Ash-
mead's table of the tribe Braconini:
Second abscissa of radius not, or scarcely, longer than the first, usually
shorter than the first transverse cubitus, or no longer. First discoidal cell
petiolate; head, thorax, and abdomen most frequently coriaceous or sha-
greened, rarely smooth and shining; antennal characters as in Bnn;,n i . , nsu
x/ricti); ovipositor short, rarely two-thirds the length of the abdomen,
most frequently much shorter; last joint of hind tarsi about the length of
the third, shorter than the second.
To the above may be added the following: Ivves more or less
completely surrounded by a yellow or testaceous ring which some-
times extends inward so as to embrace more or less of the fnce
and of the vertex; mandibles pale with black tips; first tergite
with two furrows which converge anteriorly and set off a nearly
equilateral, triangular, median area: second tergite subequal in
length with the first, longer than the third, sculptured usually
more coarsely than, and frequently differently from. tho<e
following.
The species of this genus show marked variations, not only
in intensity and arrangement of color, but in such structural
characters as the number of antennal joints, wing venation,
sculpture and proportionate lengths of the tergites, relative
length of ovipositor and abdomen, and even in the shape of the
first tergite. A misunderstanding of the range of these varia-
tions, through lack of sufficient material for study, has led to
the description of a number of species separated from others by
the use of one or more of these variable characters.
The following table will separate the seven North American
species referred to the genus. In the examination of the
100 PROCEEDINGS ENTOMOLOGICAL SOCIETY
mens a Zeiss binocular with objective a 3 and eyepiece 4, giving
a magnification of 61 diameters, was used. This high magnifi-
cation is necessary for the observation of the minute sculptural
characters used.

Specimens in the National Museum determined by Ashmead
and others as hebetor Say and juglandis Ashm. agree with Marshall's
description of brevicornis Wesm. and are identical with a specimen
from Europe determined by Schmiedeknecht as brevicornis. Chit-
tenden (Bur. Ent. Bui. 8, p. 39) suggests, on the authority of Ash-
mead, that these two species are synonyms of brevicornis Wesm.,
All of the reared specimens of hebetor and juglandis in the col-
lection are reared from hosts that breed in stored products of
various sorts, principally from various species of the genus
Ephestia. This seems to be the normal host of the species as well
as of brevicornis in Europe. All the specimens in the National
Museum that can be construed as agreeing otherwise with hebe-
tor Say differ from the original description of that species in
having the coxa? largely black not "yellowish-white." Further-
more, Say makes no mention of the black occipital spot which
appears in all dark specimens. In the description of Bracon
dorsator on the page following that of hebetor, Say observes that
dorsator agrees with hebetor in that "the first cubital cellule is
wider by one-third than the second at their junction." In all
the specimens in the National Museum this difference is at least
one-half and usually more. It seems from these facts that the
specimens reared from such hosts as those mentioned above
are not the hebetor of Say. Such being the case the hebetor of
authors must sink into synonymy \vith brevicornis Wesm., while
the hebetor of Say must stand as an unknown species.
Specimens of this species in the National Museum, in addi-
tion to those which agree with Marshall's description of the
species, show variations of practically all grades from those
in which the dorsum of the thorax and abdomen is entirely black
except the apical tergite and faint traces of the thoracic markings,
and the ocellar and occipital spots narrowly joined, to those in
which the color is largely yellowish without the typical spots on
the head, the dark color of the mesonotum reduced to three small
spots and the abdomen nearly uniformly pale. In some specimens
the head is practically all black with only faint indications of
the color pattern. The number of antennal joints in females
OF WASHINGTON, VOLU.MK XVI, 1014 10o
varies from 13 to 15 and in males from 20 to 22. The si/e ;il>->
varies considerably, the smallest males being about 2 mm. long
and the largest females about 3 mm.
The material examined consists of nearly a hundred speci-
mens from Illinois, Massachusetts, California, Nevada, Florida,
West Virginia, Ohio, New York, and the District of Columbia
together with a number of unlabeled specimens and three from
Europe. Many of these were reared from such hosts as
kuehniella, E. elutella, Plodia interpundella, and (.'ulli-r/u
nella.
Habrobracon variabilis n.sp.
Female: Length 3 mm. Face and orbit yellow, this color triangularly
extended inward behind the ocelli from each side so that the dark spot in
which are located the ocelli is nearly separated from the dark occipital

joints of the flagellum except the first but little longer than thick; palpi
yellowish.
Thorax largely dark brown above, the scutellum laterally, posterior

This- species is extremely variable in color, although the color
within a series from an individual host is quite constant, vary-
ing, as a rule, only in minor details. The paratypes show all
grades of variation, e being much paler and k much darker than
the type female. In e the ocellar and occipital spots are en-
tirely separated; mesoscutum entirely yellowish-testaceous except
a narrow median line anteriorly and a suffused spot on each
hind angle; scutellum pale throughout; propodeum somewhat
lighter, especially laterally, where it is testaceous; legs pale,
hind coxae yellowish; stigmal spot occupying nearly half of the
stigma; first tergite testaceous except triangle basally, second
tergite yellow throughout; on the remaining tergites the light
markings are somewhat more extensive and paler. Paratype i
is smaller and much darker than the type, the thoracic markings
practically obsolete and the color pattern of the abdomen very
obscure, face with a median dark line which broadens out into
a spot on the clypeus. In paratype n the ocellar and occipital
spots are broadly joined.
Habrobracon platynotae n.sp.

interrupted behind the eye with a small pale spot immediately behind the
eye and not extending mesad behind the ocelli; mandibles colored like the
face with black tips; antennae black, long, 24-jointed, uniform in thickness,
the basal flagellar joints about l times as long as thick.
Thorax black, legs testaceous except that the apical joint of the front
tarsi, the rniddle and hind tibiee and tarsi, and the coxae basally are in-
fuscated; wings dusky with the apical third hyaline, the veins fuscous.
Abdomen testaceous somewhat infuscated especially beyond the second

Bracon xanthonotus Ashmead, Proc. U. S. Nat. Mus., XI, 18SS, p. 618.
The only specimens of this species in the National Museum
are the 14 females of the type series and two others. The type
male is apparently lost. From its small size and the fact that
it had fewer antennal joints than the female it must have been a
dwarf and poorly developed specimen.
The only characters that I have been able to discover that
will separate this from the following species are variable, and I
believe that the two are conspecific, but hesitate to reduce hop-
kinsi Vier. to synonymy because of the paucity of intergrades
between the two types. One of the specimens agrees with
hopkinsi in facial markings.

Habrobracon mali Vier., Proc. U. S. Nat. Mus., vol. 44, 1913, p. 641.
The character in which Viereck considered his mali to be allied
with xanthonotus, as indicated in his description of mali, and
in which it differs from hopkinsi, is found in a manuscript table
to the species, and consists in the possession of testaceous mark-
ings on the mesoscutum. His description of the species con-
sists of a statement of- the differences between it and xantho-
notus. All of the characters used are those which an examination
of a large number of specimens of several of the other species
of the genus shows to be subject to extreme variation. This is
especially true of the color patterns of the thorax and abdomen
and the number of antennal joints.
106 PROCEEDINGS ENTOMOLOGICAL SOCIETY
H. hopkinsi was described from a series of 18 specimens reared
from Notolophus oslari. It is described as having the mesono-
tum entirely black, and yet, in the type series, there is one female
that shows the testaceous markings in the position of the notauli
quite distinctly. A careful examination of every specimen of
the type material in both hopkinsi and mali together with another
series of mali, reared by the writer from the same host and locality,
and a large series of specimens mostly reared from Clisiocampa
phivialis and C. constrida in California, some of which resemble
hopkinsi and some mali, has convinced me that the two are but
variants of the same species. Aside from the mesonotal mark-
ings there is comparatively little variation in color in the species
as at present limited, but in the number of antenna! joints there
is considerable variation. In the hopkinsi series the females have
24 to 25 antennal joints and the single male with complete antennae
has 25 joints; in the Clisiocampa series the females have 24 and the
males 28 to 29 joints; and in the mali series the females 27 and the
males 28 to 29 joints. Some of the specimens of the Clisiocampa
series show a tendency toward xanthonotus in the color of the
antennae. In addition to the material mentioned above there are
in the National Museum specimens from New Hampshire, Cali-
fornia, Maiden (Mass.?), and a series of 5 specimens from Yosem-
ite, Cal., reared from a Noctuid (?) larva. The last differ from
the type in being somewhat larger and in having the markings
somewhat paler and more extensive, and agree with the type of
mali in the number of antennal joints.
The Bracon n. sp. of Ins. Life, II, p. 349, parasitic on Clisio-
campa constrida belongs here and is a part of the material
examined.
The Bracon gelechice of New Hampshire Exp. Sta. Bui. 6, Tech.
Ser., is undoubtedly this species.

Habrobracon gelechice Johnson, Ent. News, VI, 1895, p. 324.
The female of this species can at once be distinguished from
johannseni Vier. by the greater width of the abdomen as com-
pared to its length and to the width of the thorax and by the
retraction of the terminal tergites. The male is at once distin-
guished by the color pattern of the abdomen, black bordered
with yellow which extends nearly to the middle on the second
tergite.
Comparison of the types of notaticeps (Ashm.) with those of
gelechice proves the two species to be the same, the differentiating
OF WASHINGTON, VOLUME XVI, 1914 107
characters as given by Ashmead in his description of the latter
species, that is, the color of the leg* and the number of antennal
joints, being both very variable characters.
The only female of this species in the type series lacks entirely
the yellow tergal color ascribed to the species by Ashmead in
his description. Unfortunately also the head is missing. It i-
possible that the female and the males are of different specie-,
the opposite sex of each of which has not been identified. The
exact status in this respect can not be satisfactorily determined
except by the rearing of more material under careful observation.
One female from Kansas collected by C. L. Marlatt and labeled
by Ashmead Bracon notaticeps, which differs from the type in
having the abdomen brown on the sides, has been provisionally
referred to this species.

number of antennal joints, and color of hind femora, are all very
subject to variation throughout the genus. The types of the two
species differ also in the shape of the first tergite. In johannseni
the sides of this segment beyond the spiracles are straight and
parallel while in tetralophce they are curved and slightly divergent.
Examination of a large series of specimens from other sources
shows that the shape of this tergite varies from the form shown
in johannseni to those showing even more curvature and diver-
gence than in the type of tetralophce. In all of the males the first
tergite is of the form exhibited by the type of johannseni.
Besides one of the type specimens of johannseni and three
of tetralophce the following material was examined: a large series
reared by J. E. Graf at Los Angeles and El Monte, Calif., from
Phthorimea operculeUa under Chittenden No. 2229; 3 specimens
from the same host at Norfolk, Va,, Chittenden No. 2721 a ; 12
females and 1 male from Desmia funeralis in Fairfax Co., Va.,
Quaintance No. 5569, J. F. Strauss; 2 females from the same host
from the Ashmead collection; 1 female from Riley Co., Kans.,
Marlatt; 2 females from Champaign, 111., 2 females from Oswego,
N. Y.; 2 females from Salineville, Ohio; 1 female from Franklin
Co., Ark., Webster; and 1 female from Agr. Coll.. Mich. All the
California parasites of Phthorimea resemble the type of johannseni
in color except that the light margin of the abdomen is somewhat
more distinct. In this series nearly all gradations in the shape of
the first tergite are found. The Virginia parasites of Desmia agree
in color of the legs with tetralophce and show some variation in the
shape of the first tergite, but are mostly somewhat larger than the
tyoes. The New York specimens agree with tetralophce except
that the orbital ring is somewhat paler and more distinctly de-
fined. In the Kansas specimen the black color of the abdomen is
replaced by brown, and the border is yellow, while all of the legs
are pale. In the two specimens reared from Desmia without
locality and the two Illinois specimens the reduction of the abdomi-
nal color is carried still further, while the mesopleurae and prono-
tum laterally are more or less testaceous to yellowish. The num-
ber of antennal joints in the female varies from 19 to 36, the
smaller specimens having the smaller numbers. In the males of
the Phthorimea series the antennae are from 23 to 27 jointed;
neither of the other males has the antennae entire.

Female: Length, 0.50 mm. Black, the scape, pedicel and proximal three
tarsal joints dusk}r lemon yellow, the trochanters and knees pallid; 'wings
obscurely, slightly fumated. subhyaline; cephalic tibiae lighter.
Differs from the other European species, diana Girault, in being black
instead of brown, in having the second funicle joint more than twice the
length of the first and only slightly shorter than the third. In regard to the
three North American species, it is most similar to pullicrura with which it
may be confused; however, upon comparison of specimens, pullicrura is
seen to differ in that the fore wings are more deeply infuscated and not
quite so broad, their caudal margin more concavely curved and the scape
and pedicel are darker. Also in luna the midlongitudinal line of discal
cilia is longer and may include as many as eleven cilia. Otherwise I can-
not distinguish between the two. It is distinct from other North American
species. Of the Australian species (harveyi, galtoni, linmri) it is distinct
from all excepting linnan, which it resembles closely. However, linncci dif-
fers in that the proximal tarsal joints are longer, the legs lighter, the fore
wings more deeply infuscated, the scape and pedicel dark. The Australian
