TECHNICAL RESULTS FROM THE GIPSY MOTH PARASITE LABORATORY.
n. Descriptions of Certain Chalcidoid Parasites.
By J. C. Crawford,
Assistant Curator, Division of Insects, U. S. National Museum.
INTRODUCTION.
The new species described in this paper came from material
imported from Japan and Europe for the purpose of rearing parasites
of the gipsy moth and the brown-tail moth. The work of rearing
these parasites is conducted at the Gipsy Moth Parasite Laboratory,
now situated at Melrose Highlands, Mass.
In the study of these parasites a Zeiss binocular microscope has
been used with magnifications of from 24 to 35. In cases where the
description states that the series includes more than one specimen of
each sex the description is drawn from one specimen of each sex, and
any variations in the other specimens, which are designated as para-
types, are cited.
In considering the genus CTialcis it has been deemed desirable to
display in a synoptic table not only all of the species of this genus
which have been introduced purposely as parasites of the gipsy moth
or the brown-tail moth or accidentally included in shipments of para-
site material, but also all of the species of the genus known to occur
in the United States. In the same way it has been deemed desirable
to publish a table separating the common American form from the
two species of the genus HypopteroTnalus accidentally included in
shipments of parasite material, and also to separate in a synoptic
table the different Japanese species of the genus Pleurotropis which
have three funicle joints. As pointed out, P. atamiensis belongs
probably to an undescribed genus.
Family CHALCIDID^E Walker.
STabfainily CH^^LCIUIN^gC Howard.
Tribe CHALCIDINI Asl-in:veaci.
Genus CHALCIS Fabricius.
Since some of the species of CTialcis from Europe and Japan are
being introduced into this country, it appears best to give a table of
all of the species of the genus known to occur in the United States
and to include in this table the exotic species which are involved.

14 EESULTS FROM GIPSY MOTH PARASITE LABORATORY.
In the following table and descriptions of species the term " tubercle
of hind coxae " refers to a small projection on the ventral side of certain
species (fig. 9). The tubercle of the hind femur is the small elevation
on the imier side near base and on the lower margin of the femur
(fig. 20).
In all of the figures showing the carina which separates the malar
space from the face, the drawings are made facing the left.

armed with a small tubercle; the inner side of the hind femora is

Both of the Cuban species, Chalcis rohusta
and C. incerta, are to be found in southern
Florida. The massive basal tooth of the
hind femora distinguishes them from the
other species in the United States.
CHALCIS COLORADENSIS Cresson.
Chalcis coloradensis Cresson, Trans. Amer. Ent. Soc, iv, p. 60, 1872.
In the male of this species the hind femora are black, except the
apex, which is yellow; the female, however, has the femora red;
the hind femora have on the lower edge near base an indistinct
tubercle. I am unable to distinguish C. tacMnse. Howard from this
species.

of flies of the family Sarcophagidae, which are scavengers on the dead
pupae of the gipsy moth.

the genus Pleurotropis.

Japan which have 3 joints in the funicle; P. atamiensis Ashmead has
4 joints in the funicle and is probably an undescribed genus.
