REVISION OF THE GENUS EXETASTES — CUSHMAN 297 



Wings: Apical abscissa of radius strongly curved at base, more 

 than a half longer than basal abscissa; areolet petiolate, second inter- 

 cubitus much longer than other sides and curved; second discoidal 

 cell broad, second recurrent more than two-thirds as long as basal 

 abscissa of subdiscoideus, strongly curved above; nervulus strongly 

 postfurcal; abscissula much less than twice as long as intercubitelia. 



Abdomen stout, weakly compressed at apex, first tergite little more 

 thf-n twice as long as broad at apex, second about as long as broad 

 at base; ovipositor straight, sheath a little more than half as long as 

 first tergite. 



Head and thorax immaculate black, abdomen ferruginous with peti- 

 ole black at extreme base, venter ferruginous; coxae, trochanters, 

 front and middle femora largely, apical half of hind tibia, and hind 

 tarsus black, hind femur ferruginous, legs otherwise more or less dis- 

 tinctly testaceous or fuscotestaceous; wings deeply infumate; pubes- 

 cence of head and thorax dense, conspicuous, and dark cinereous. 



Male. — Differs very Uttle from female beyond having the wings 

 much paler. 



Type locality. — San Diego, Calif. 



Type. — Acad. Nat. Sci. Philadelphia no. 1611. 



Remarks. — Of this species I have seen four females and one male, 

 all from California. These include the type, a female homotype com- 

 pared by myself with the type and taken with another female in Los 

 Angeles County by D. W. Coquillett, one female from Claremont 

 (collection of Cornell University), and one male from Walnut Creek, 

 Contra Costa County, April 19, 1913, J. C. Bridwell. 



41. EXETASTES ERYTHROGASTER, new species 



Very closely related to zelotypus, differing structurally from the 

 above description of that species only in its distinctly longer malar 

 space, this in the present species being about three-fourths as long 

 as basal width of mandible in female and only slightly shorter in 

 male. 



Both sexes differ from zelotypus by having the front and middle legs 

 entirely black except the faintly reddish apices of the femora, the 

 hind leg except femur entirely black, the first tergite and venter 

 largely black. 



Type locality. — Unknown. 



Allotype locality. — Corvallis, Oreg. 



T?/pe.— U.S.N.M. no. 51821. 



Paratype. — Canadian National Collection. 



Remarks. ^One female (the holotype) without data; and two males, 

 the allotype captured April 24, 1897, and the paratype April 25, 1923, 

 at Oliver, British Columbia, by C. B. D. Garrett.
