well as middle tibia, beneath, fuscous; all tarsi wliite, apical joint 

 fuscous; wing veins and stigma fuscous; first tergite rufous, others 

 blackish with lateral and apical margins more or less j'ellow. 



Ty2)e locality. — Globe, Arizona. 



Type.— Cat. No. 22148, U.S.N.M. 



One specimen taken on Tliw-beria tJies-pesioides b}' C. H. T. Townsend. 



CREJMASTUS BRUNEICEPS, new species. 



Female. — Length, 6 mm.; antennae, 4 mm.; ovipositor, 2 mm. 



Runs in my key to females to 'platynotae Cushman and agrees with 

 all key characters, but differs from that species as follows: Eyes very 

 slightly convergent below; clypeus less strongly convex and rather 

 broadly rounded at apex: face opaque; diameter of ocelli fully two- 

 thirds as long as postocellar line; pronotum laterally shining, finely 

 regulose; petiolar area densely, transversely regulose; second tergite 

 distinctly more than four times as long as wide at base. 



Head brownish, without distinct markings; scape, pedicel, and 

 basal joint of flagellum pale below; thorax entirely ferruginous; 

 propodeum v.ath a duslq^ spot in basal middle; legs as in platynotae, 

 except that the contrast in color of coxae and trochanters and femora 

 is less; abdomen largely ferruginous, tergites except first more or less 

 fuscous. 



Type locality. — Washington, District of Columbia. 



Type.— Cat No. 22149, U.S.N.M. . 



One female taken by H. L. Viereck, July 2, 1910. 



Subgenus ZALEPTOPYGUS Viereck. 



CREM.4STUS (ZALEPTOPYGUS) ALBIPENNIS (Cresson). 



Porizon albipennis Cresson, Pre. Ent. Soc. Phila., vol. 4, 1865, p. 287, female. 

 In my key to females the type runs to hilinealus Cushman, but is at 

 once distinguishable by its shorter ovipositor. Cresson states that 

 the ovipositor is longer than the abdomen, but that portion of it 

 that is exserted, which is the portion considered in the key, is much 

 shorter. It looks more like vierecMi Cockerell, and may be the female 

 of that species, though it differs somewhat in the color of the abdomen. 



CREMASTUS (ZALEPTOPYGUS) ACICULATUS Davis. 



Cremastus aciculatvs Davis, Trans. Amer. Ent. Soc, vol. 24, 1897, p. 364, male. 



This species runs in my ke}" to males to reiiniae (Cresson), but, 

 as indicated by the original description, is much more contrastingly 

 colored, the thorax generally black with the pronotum red. In this 

 character it is more closely allied to rosae Cushman and plesius 

 Cushman, both of which are known only in the female, and is very 

 possibly the male of one of these.
