but becoming tinged with fulvous on middle of propodeum. A 

 little dusky or blackish hair on each side of vertex and behind 

 summit of eyes. Facial foveae dull whitish, tinged with brown. 

 Hair of legs whitish, becoming fuscous on outer side of middle 

 tibiae and on middle and hind basitarsi. Hair on inner side of 

 tarsi brownish ferruginous. Scopa of hind tibiae white, ample, 

 moderately compact, the hairs entirely simple, those on lower 

 margin long and curved upward, those on dorsal margin becom- 

 ing tinged with fuscous toward the base. Abdomen without 

 bands, the hair rather short and thin, blackish on disk of tergites 

 3 to 5, and whitish and longer, especially on each side, on the 

 apical margin of tergites 2 to 5. Hair of tergites 1 and 2 entirely 

 dull white. Apical fimbria brown or fuscous. Sides of propodeum 

 entirely nude. Length, about 11.5 mm.; anterior wing, almost 

 9 mm. 



Male. — Colored like the female, but the flagellum of antennae 

 dark, tarsi brownish ferruginous, and disk of clypeus with a 

 transverse yellow mark on anterior half. Margin of yellow mark 

 more or less distinctly notched in middle and on each side above. 

 Pubescence considerably longer and much looser than in the fe- 

 male, fulvous or ochreous, becoming paler below and on the legs. 

 Hair of abdomen short, thin, and blackish on disk of tergites 

 3 to 5 and on apical part of tergite 2, that on tergite 1 and along 

 sides of following segments rather long and light. Apical fimbria 

 concolorous with hair of thorax. Head transverse and much 

 broader than thorax, the anterior margin between bases of 

 mandibles convexly arcuate. Mandibles long, simple, moderately 

 stout, and curved. Clypeus more than twice as broad as high. 

 Labrum small, shaped as in female, but without the preapical 

 groove. Process of labrum about twice as broad as long, broadly 

 truncate and more or less emarginate at apex. Antennae rather 

 long and slender, the middle joints of flagellum about one and 

 one-half times longer than thick. Joint 3 slightly longer than 

 either 4 or 5, which are about equal. Cheeks broad and subangu- 

 late, the angle well above middle of eye. Sculpture similar to 

 that of female, but less granular, the surface more shining, with 

 setigerous punctures apparent on clypeus, face, cheeks, most of 

 the thorax, and abdomen. Abdomen slender, elongate-oval. Geni- 

 tal armature similar to that of macrocephala. Medio-apical lobes 

 of stipites little developed. Parameral lobes large, strongly con- 

 vergent on basal half, then abruptly angulate on inner margin 

 at the beginning of the elongate, oblong apical expansion, which 

 is slightly tapered to apex. Sagittae slender, depressed, slightly 

 fusiform toward base, and attentuate toward apex. Length 8-9 

 mm. ; anterior wing 6.8-7.3 mm.
