 young peach stems by Mr. W. S. Fisher in December, 1910, and

STIGMUS INORDINATUS HUBBARDI, new subspecies. 



Female. — Separated from typical inordinatus by the absence of the 

 frontal impressed line and having all the femora pale. 



Male. — Differs from typical inordinatus in the eyes converging 

 more strongly to the clypeus, so the distance between them at the 

 clypeus is subequal with half the distance between them at the 

 vertex. The legs are also pale. 



Palm Springs, California. Many males and females bred from 

 'pupae in Polyporus, issuing March 1. Collected by Mr. H. G. Hub- 

 bard, for whom the subspecies is named. 



Type.— Cat. No. 13771, U.S.N.M. 



This may be raised to a species eventually, as the male presents 

 good differences. 



STIGMUS FRATERNUS COLORADENSIS, new subspecies. 



Female. — Differs from fraternus Say in the apical joint of the

GONOSTIGMUS, new genus. 



Habitus very like Stigmus Panzer, but differing at once in the shape 

 of the head. Head seen from the front, excluding clypeus, distinctly

 narrowing posteriorly; facial quadrangle strongly narrowed below; 

 eyes large and broadened below as in Crabro, but not as strongly so;
