NORTH AMERICAN BUPEESTID BEETLES 111 



clothed with short, Avhitish hairs; prosternal lobe broad, strongly 

 declivous, and broadly rounded or subtruncate in front; prosternal 

 process broad, the sides parallel to behind the coxal cavities, without 

 dentiform reflexion of the edge, then abruptly narrowed to the apex, 

 Avhich is acute. Tibiae slender, feebly arcuate, and the anterior and 

 middle pairs with a small tooth on the inner margin at apex, the 

 posterior pair simple. Posterior tarsi distinctly shorter than tibiae, 

 and the first joint about equal in length to the following three joints 

 united. Tarsal claws dissimilar, anterior ones cleft near the tip, 

 middle ones slightly more deeply cleft, and the posterior ones cleft 

 near the middle, the teeth about equal in width, and the inner one 

 sometimes feebly turned inward. 



Length, 9 mm. ; width, 2.5 mm. 



Female. — Differs from the male in having the front of head vio- 

 laceous cupreous, lateral sides nearly parallel, and the surface more 

 sparsely punctate; first and second abdominal segments convex at 

 middle, and without a median groove; tibiae unarmed at apex, and 

 the claws cleft near the middle, the inner tooth broad and very short. 



Redescribed from the lectotype No. 3478 in the Academy of Nat- 

 ural Sciences of Philadelphia. 



Type locality. — Texas. 



Distribution, — Material examined. Texas: No definite locality. 



Variations. — No variation was observed in the few examples ex- 

 amined except in size, which varied in length from 9 to 10 milli- 

 meters. 



Host. — Unknown. 



This species seems to be rare in collections, as only four specimens 

 have been examined by the writer, all of which are probably from 

 the Belfrage collection. Chamberlin (1926) records it from Arizona 

 and Illinois, but the latter record is probably from an erroneously 

 identified or incorrectly labeled specimen. He also records a speci- 

 men in the United States National Museum from Kerrville, Tex., 

 but this is the new species benjamini described above. The species 

 is closely allied to vittaticollis Randall and benjamini Fisher, but can 

 be separated from both these species by the characters given in the 

 table. 



34. AGRILUS PILOSICOLLIS, new species 



Female. — Form resembling granulatus Say, feebly shining, and 

 slightly flattened above; olivaceous brown, with the head and pro- 

 notum more or less cupreous; elytra ornamented with yellow pubes- 

 cent spots; beneath cupreous, and more shining than above. 



Head Avith the front rather wide, nearly flat, about equal in width 

 at bottom and top, the lateral margins arcuately expanded at vertex, 

 and with a longitudinal grooA r e extending from the occiput to the
