EEVISION OF THE GEJS^US EXETASTES — CUSHMAN 299 



not more than twice as long as broad at base; eyes rather weakly 

 convex, hardly as long as width of face, weakly convergent below; 

 diameter of ocellus more than half as long as postocellar line; antenna 

 very slender, attenuate at apex, nearly 60-jointed, first joint of 

 flagellum nearly six times as long as thick, all other joints much longer 

 than thick; propodeum with distinct median trace of apical carina; 

 legs slender, claws simple; second recurrent weakly curved above. 



Color as in zelotypus except hind legs entirely black and front and 

 middle legs more largely so. 



Type locality. — Colorado. 



Ty2)e. — Acad. Nat. Sci. Philadelphia no. 1614. 



Remarks. — In addition to the type I have seen four females, one of 

 which, a homotype compared by myself, is from Albert Lake, Oreg., 

 June 17, 1934, Joe Schuli, collector; two taken on snow on Pikes Peak, 

 Colo., July 20, 1901, by Dyar and Caudell; and one taken in Michigan 

 by C. H. T. Townsend. 



45. EXETASTES ALTERNATIPES, new species 



A small replica of affinis, differing only as follows: 

 Female. — Length 10 mm, antennae broken. 



Hind femur, except extreme apex, bright ferruginous; tibia, except 

 apical tliird, dark reddish. 



Type locality. — Bernadillo County, N. Mex. 



Type.— U.S. ISl.M. no. 51824. 



A single female taken in May 1896 by B. Brown. 



46. EXETASTES DEUTEROMAURUS Dalla Torre 



Exetastes rnaurus Cresson, Proc. Acad. Nat. Sci. Philadelphia, 1878, p. 370; female 



(preoccupied by maurus Desvignes). 

 Exetastes deuteromaurus Dalla Tobre, Catalogus hymenopterorum . . ., vol. 3, 



pt. l,p. 71, 1901. 



The only specimen that I have seen is the type. 



Among the black species this is very distinct because of the unusually 

 short stout abdomen and the conspicuously hairy head and thorax. 



Female. — Head and thorax with dense long erect hair, especially 

 conspicuous on temples; temples weakly convex, strongly receding; 

 face very densely and coarsely punctate, more than twice as broad as 

 long and broader than length of the slightly convergent eyes; ciypeus 

 two-tliirds as long as broad and about two-tliirds as broad as face, 

 strongly convex basally, especially in middle, basal portion densely 

 and coarsely punctate, apical portion also coarsely but more sparsely 

 punctate; cheeks in front view slightly concave, their extended angle 

 acute; malar space fully two-thirds as long as basal width of mandibles; 

 postocellar and ocellocular lines equal and nearly three times as long
