hairs, and with an obsolete pubescent spot at sides of third segment ; 

 first segment feebly convex, without a median groove; last segment 

 broadly rounded at apex; vertical portions of the first segment 

 slightly more pubescent than rest of segments; pygidium sparsely 

 punctate, and without a projecting carina. Prosternum obsoletely 

 granulose, sparsely punctate, and clothed with a few rather long, 

 recumbent, whitish hairs; prosternal lobe broad, feebly declivous, 

 and broadly, but not deeply, arcuately emarginate in front; pros- 

 ternal process broad, the sides strongly expanded behind the coxal 

 cavities, and the apex subtruncate, with an acute tooth at middle. 

 Sides of mesosternum and metasternum more or less densely pubes- 

 cent. Tibiae slender, nearly straight, and the anterior and middle 

 pairs armed with a small tooth on inner margin at apex. Posterior 

 tarsi distinctly shorter than tibiae, and the first joint about as long as 

 the following three joints united. Tarsal claws dissimilar, anterior 

 ones cleft near tip, and the teeth nearly equal in length ; middle, and 

 posterior claws cleft near middle, the inner tooth broad, much shorter 

 than the outer one, and not turned inward. 



Female. — Differs from the male in havings the head uniformly 

 cupreous brown, the lateral margins nearly parallel, front about 

 equal in width at bottom and top, and the surface not so distinctly 

 rugose ; prosternum smoother ; tibiae without a distinct tooth at apex, 

 and the tarsal claws cleft near the middle on all feet. 

 Length, 3-3.5 mm. ; width, 0.85-1 mm. 

 Type locality. — San Diego, Tex. 



Other localities. — Texas; Zavalla County, Nueces River; Sabinal; 

 Devil's River ; Del Rio ; New Braunfels. 



Type, allotype, and paratypes. — Cat. No. 41001, U.S.N.M. 

 Paratypes. — Collection of H. F. Wickham. 



Described from 14 specimens (one type), all from Texas. Type, 

 allotype and one paratype collected at the type locality on May 18, 

 by E. A. Schwarz; 4 paratypes collected in Zavalla County, Nueces 

 River, April 26-27, 1910, by Hunter and Pratt ; 2 paratypes collected 

 at Sabinal, May, 1910, and June 3, 1910, by Pierce and Pratt; 3 para- 

 types collected at Devil's River, May 3-5, 1907, by E. A. Schwarz 

 and F. C. Pratt; one paratype collected at Del Rio, June 22-27, by 

 H. F. Wickham, and another paratype collected at New Braunfels, 

 June 16, by the same collector. 



This species resembles ornatulus Horn very closely, and is prob- 

 ably confused with that species in some of the collections. It can, 

 however, be separately from ornatulus by the pronotum and elytra 

 being bronzy brown and strongly shining, the anterior pubescent 

 design on the elytra entire and longitudinally arcuate, and by the 

 male genitalia having the exterior margin of the lateral lobes 

 distinctly angulated.
