86 GEO. H. HORN, M. D. 



A. hirsutus Horn. — Oblong, moderately elongate and convex, nearly par- 

 allel, ferruginous brown, feebly shining. Autennie rufotestaceous. Head mod- 

 erately convex, rather closely punctate, punctures coarse across the occiput, finer 

 and sparser at middle, transversely wrinkled at the sides in front. Clypeus im- 

 pressed in front, eniarginate at middle, on each side less broadly rounded, sides 

 arcuate, geute feebly prominent, obtuse. Thorax twice as wide as long, slightly 

 narrowed in front, sides anteriorly arcuate, posteriorly nearly parallel, hind an- 

 gles rounded, base rather strongly arcuate with distinct marginal line, disc mod- 

 erately convex, with intermixed punctuation of coarse and fine punctures, the 

 coarse punctures numerous, but not dense along the base and sides, sparse and 

 smaller at the anterior portion of the disc. Elytra as wide as the thorax, humeri 

 slightly dentate, sides feebly arcuate, strife deep, distantly punctured, intervals 

 feebly convex, crenate on the inner side, summit with a row of fine punctures 

 on the outer side, each bearing a short, erect, yellowish hair. Mesosternum 

 opaque, rather coarsely punctured, carinate between the coxfe. Metasternum 

 smooth. Abdomen coarsely sparsely punctured at the sides, smooth at middle, 

 the segments crenate in front. Anterior tibife tridentate externally and subcre- 

 nate above. Posterior femur smooth, the marginal line fine, almost obsolete, 

 extending half way to base, the tibia with accessory spinule, the first tarsal 

 joint as long as the long spur. Length .16-.18 inch ; 4-4.5 mm. 



This species was originally described from two much mutilated 

 specimens found dead and disarticulated. There are now two per- 

 fect specimens, from which the description can be more accurately 

 given. 



The clypeus is rather more deeply eniarginate than usual in this 

 series, so that when viewed directly from above there appears to be 

 an angulation each side. There would, however, be no difficulty 

 should the species be referred to the angulate series as the table would 

 lead directly to kevtventris, from which it is very easily known. The 

 presence of the short erect hairs on the elytral intervals will make 

 the species known wherever it may be placed. Occurs in Arizona, 

 Camp Grant and southward.
