ART. IG WASPS OF THE SUBFAMILY BRACONINAE MUESEBECK 49 



posterior face from the long, rather flat, dorsal face; pleura pohshed, 

 rather strongly pilose; mesopleural furrow weakly impressed, not fo- 

 veolate; posterior coxae smooth, pubescent; posterior femora rather 

 short and stout; spurs of hind tibiae apparently of equal length and 

 shorter than half the hind basitarsus; last segment of hind tarsi 

 not longer than the third; second cubital cell small, triangular, peti- 

 olated; radius arising from about middle of stigma; first abscissa of 

 mediella about as long as the second or indistinctly shorter; nervel- 

 lus straight; discoidella very weak, obsolete at base; abdomen slen- 

 der; first tergite a little longer than broad at apex, with two promi- 

 nent dorsal longitudinal keels extending from the base to the apical 

 third, and usually with a few weak longitudinal striae between these 

 keels; second and following tergites polished; ovipositor sheaths 

 very nearly as long as the body. Ferruginous; head black, with 

 clypeus, middle of face, cheeks, and temples often more or less reddish; 

 mesonotum and propodeum ferruginous, sometimes more or less infus- 

 cated or blackish; pro pleura and metapleura usually ferruginous or 

 fuscous, the meso pleura black; pro and meso pectus black; anterior 

 and middle legs brownish black, the coxae and trochanters darkest; 

 hind coxae and trochanters brownish black; their femora testaceous; 

 posterior tibiae and tarsi brown; wings infumated; abdomen entirely 

 ferruginous. 



Male. — Essentiall}^ as in the female; but the thorax is darker, 

 being entirely black except for ferruginous markings in the region of 

 the parapsidal grooves. 



Type.—C&t. No. 28688, U.S.N.M. 



Type locality. — Iluachuca, Arizona.

23. BASSUS ACROBASIDIS Cushman 



Bassus acrobasidis Cushman, Proc. U. S. Nat. Mus., vol. 58, 1920, p. 289. 



Type. — In the United States National Museum. 



Exceedingly similar to erythrogaster, and sometimes very difficult 

 to distinguish from that species. Hov/ever, the characters given in 

 the key w.dl nearly alwa3^s separate them readily. 



Face broader than long to the apex of clypeus; malar space 

 usually a little longer than in erythrogaster; antennae distinctly 

 longer, usually 32 to 36 segmented, rarely in very small specimens 

 with 31 segments; the apical flagellar segments in the female slender, 

 elongate; third segment of labial palpi short but distinctly longer 

 than broad, not as in calcaratus and alhed species; parapsidal furrows
