REVISION OF THE GENUS EXETASTES — CUSHMAN 271 



Wings: Apical abscissa of radius moderately curved at base, barely 

 a half longer than basal abscissa; areolet slightly irregular, shortly 

 petiolate; second discoidal cell rather narrow, basal abscissa of sub- 

 discoideus about a half longer than second recurrent; second recurrent 

 flexed above; nervulus shortly postfurcal; abscissula twice as long as 

 intercubitella. 



Abdomen broad, weakly compressed at apex; first tergite depressed 

 throughout, not nearly twice as long as broad, second barely as long 

 as broad at base; ovipositor faintly recurved, sheath nearly as long as 

 first two tergites. 



Head and thorax black, face, scape below, large triangular mark 

 on each side of mesoscutum anteriorly, scutellum, and postcutellum 

 yellow; clypeus light brownish at base, stramineous at apex; mandibles 

 partly brownish or yellowish; flagellum blackish; coxae and bases of 

 trochanters dark brown, front and middle legs otherwise yellow, hind 

 leg yellow with femur and tibia apically broadly brown, basitarsus 

 dark reddish; wings yellow hyaline with apices broadly dilutely in- 

 fumate, tegulae stramineous, more or less brownish discally; abdomen 

 yellow, more or less stained with reddish, segments beyond fourth 

 largely blackish; sheath black. 



Alale. — Essentially like female, but antennae longer and more 

 slender, 44-jouited; claws not pectinate; clypeus, mandibles, malar 

 space, and anterior margin of pronotum medially also, yellow; mark- 

 ings of mesoscutum usually extending backward more or less along 

 notauli; front and middle trochanters entirely and their coxae mostly 

 yellow; fifth tergite yellow; genital sheath pale at apex. 



Type locality. — Wliite Mountains, N. Mex., south fork of Eagle 

 Creek, about 8,000 feet. 



T?/i)e.— U.S.N.M. no. 51803. 



Paratypes. — American Museum of Natural History; Cornell Uni- 

 versity.

14. EXETASTES BUCCATUS, new species 



Female. — Length 10 mm, antennae 8 mm. 



Related in the thick head and stout abdomen to the three imme- 

 diately preceding species, this species differs from the above description 

 of propinquus principally as follows:
