Holotype. — Male, Jemez Springs, New Mexico, July 1, 1916 (John 

 Woodgate), in collection of Cornell University. 



This species looks very similar to snoworum, but differs from the 

 latter in having the calcaria pale, the first segment of the flagellum 

 subequal in length to the second, and the apical fringes of the abdom- 

 inal segments black. It is a more robust species than digressa and 

 can be separated from that species by the characters given in the 

 key. The genitalia are like those of ohscura, and are therefore not 

 figured. 



Group CREON 



Females with the head wider than the thorax; thorax subhexag- 

 onal; scutellar scale present; pygidium pubescent. Males with the 

 head scarcely as wide as the thorax; anterior margin of pronotum 

 not emarginate medially ; first segment of abdomen strongly nodose ; 

 pygidium pubescent; and posterior trochanters produced beneath 

 into a prominent tooth.

SPECIMENS EXAMINED 



Texas: Male, Pittsburg, July 28, 1904 (F. C. Bishopp). 



This species and eminentia Mickel are very easily recognized by the 

 prominent tooth on the trochanters of the posterior legs. They are 

 not at all closely related, however. The genitalia are very dissimilar, 

 the pygidial areas of the two are unlike and in other respects they 

 show only distant relationships. The ferruginous color of the head, 

 thorax and first two abdominal segments, and the pubescent pygidium
