Taschenberg's brevicornis was described from a male from Illinois (a male ingenuus Cresson) and a female from Mexico (a female azureus Cresson). I have recently had an opportunity to examine these specimens, both of which are in good condition. The male is clearly marked as the type.
Female. — Length 10.5-18 mm. Black, rendered by the pubescence a deep blue or violaceous; pubescence nowhere silvery, even on the lower front; wings wh^ n y and uniformly fuliginous, violaceous. Front very broad, MID .62-.66 X TFD; front rather strong'y convex; UID .85-.95 X LID. Ocelli forming an obtuse angle in front, POL:OOL about as 3:4. Antennal segment three about twice as long as its greatest thickness, equal to only .35-. 45 X UID. Propodeum with a well-defined declivity, with numerous erect hairs. Front basitarsus with three (rarely four) comb-spines, the apical one usually slightly shorter than second tarsal segment. Hind wing with submedian cell rather broadly rounded apically and sometimes appendiculate.
Male. — Length 10-17 mm. Color as in female; wings wholly fuliginous; body wholly without silvery pubescence. Scape hairy, front rather densely hairy, propodeum with numerous erect hairs. Front broad, MID .61-.66 X TFD; UID subequal to or very slightly exceeding LID. Ocelli in a broad, flat triangle, POL slightly less than OOL. First four antennal segments in a ratio of about 30:10:22:28, segment two relatively shorter than in other species of this genus, segment three only slightly less than twice as long as thick (see fig. 29 in Evans, 1950). Last segment of front tarsus distinctly asymmetrical. Hind wing as in female. SGP as in the following species. Genitalia with the basal hooklets double; aedoeagus bearing rather numerous small setae; parameres relatively long and slender; apical, mesally-directed portion of digiti moderately strong (see fig. 19 in Evans, 1950).
Distribution. — This relatively large and distinctive Evagetes is not well represented in most collections, although it occurs throughout all of the United States, except in the Lower Austral Zone, as well as across the entire length of southern Canada. Doubtless it occurs throughout the Mexican Central plateau, but so far it has been taken only in Chihuahua and the state of Mexico. (Map 23.)
Mexican specimens examined. — 2 9 9,5 8 8. Chihuahua: 1 8 , Summit NE San Jose Babicora, 7700 feet, 4 July 1947 (CDM) [AMNH]. Mexico: 2 9 9,4 $ 8 , Teotihuacan, about 7500 feet, June, July (HEE, PDH, RRD) [MCZ, CIS, MSU].

Evagetes ingenuus is a species of spider wasp in the family Pompilidae.
