DESCRIPTIONS OF NEW HYMENOPTERA. 1
By J. C. Crawford,Assistant Curator, Division of Insects, U. S. National Museum.
In this paper some new parasites from the United States aredescribed, together with two new species of bees which were foundwhile arranging part of the collections of bees. There are also newspecies of parasites from Japan, described mostly from a small col-lection of reared Hymenoptera sent in for determination by Mr.Takeshi Fukai, of Konosu, Saitama, Japan.
Family ANDRENID^.NOMIA HOWARDI, new species.Female.?^Length about 9 mm. Black, with opalescent bands onthe apical margins of segments 1-4; face below antennae with coarsesparse punctures; those on the clypeus more scattered; aboveantennae with fine scattered punctures; mesonotum anteriorly andlaterally with close, coarse pimctures; disk of mesonotum and meta-notum (postscutellum of authors) almost impimctured, polished;truncation of propodeum with sparse, large, setigerous punctures,the surface between with fine shallow punctures and almost hiddenby the silky white pubescence; metapleurse striate; wings subhya-line, the apical margin with a broad infuscated band; legs brown,the hind tibiae and tarsi reddish-brown; outer spur of hind tibiaebent at an obtuse angle; abdomen finely reticulated and with sparse,fine punctures; opalescent bands, except the first, broad, but notcovering the depressed apical margins of the segments, the dark por-tion punctured.One specimen from San Jose de Guaymas, Mexico. Dr. L. O.Howard^ collector.Type.?Cat. No. 13455, U.S.N.M.Named for Dr. L. O. Howard.

striae (in mesiUensis the metapleurse have a few coarse striae and theupper part pimctured); mesopleurse with finer punctures; puncturesof truncation of propodeum separated by two or more times theirown diameter, the sculpture of the intervening spaces much finer;hind tibiae and tarsi brown; outer spm^ of hind tibiae at apex bent at Iright angles; punctures of abdomen coarser and closer and lineola- |tion more apparent; opalescent bands much narrower. \One specimen from San Jose de Guaymas, Mexico.
