Otidocephalus subglaber, new species. 



Head black, nearly smooth, foveate between the eyes ; the latter separated by 

 about half of their own width ; beak short, stout, smooth at middle, punctate at apex, 

 at sides narrowly striate, sides with a few, short white hairs, which are denser 

 around the eyes ; antennas reddish, club piceous. , Thorax rather strongly declivous 

 in front and feebly impressed ; sides feebly arcuate, towards base feebly constricted ; 

 disk very sparsely punctate with widely scattered punctures, each bearing a coarse 

 white hair. Scutellum very small, densely clothed with white pubescence. Elytra 

 black, slightly longer than twice as wide at base ; humeri rounded ; sides gradually 

 widening towards apex ; surface with regular rows of coarse, deep and closely placed 

 punctures, the three inner rows impressed ; intervals convex, with a row of widely 

 placed smaller punctures, each bearing a single coarse, recumbent white, or erect 

 finer, dark hair. Underside and legs black ; clothed with finer white hairs ; femora 

 with a small tooth; front tibiss narrow, slightly sinuate within. Length 3.5 mm. 



Arizona (Dietz). 



The very sparsely placed white coarse, and finer dark hairs of 

 elytra, together with the impressed elytral stride, the form of thorax 

 and the interocular fovea readily distinguish this species. 



Otidocephalus arizonicus, new species. 



Head black, coarsely, densely punctate, black setae erect, white setas sparse, short, 

 recumbent, more dense and longer between the eyes ; the latter separated by about half 

 their own width ; beak about as long as the thorax, stout, bistriate on each side, striae 

 impressed and rather coarsely punctate, discal striiK extending to about basal half, 

 lateral stride extending to apex, surface at apex irregularly punctate ; antennse red- 

 dish, club piceous, first joint of funiculus stout and as long as second and third 

 together, club elongate oval. Thorax convex ; sides arcuate, feebly constricted at 

 base ; disk closely and rather coarsely punctate, median smooth line not clearly 

 defined ; surface with numerous, erect, white and black set^e, the white denser at mid- 

 dle of apex ; at base and sides a few radiate-pectinate white hairs. Scutellum densely 

 covered with white pubescence. Elytra black, more than twice as long as wide; 

 humeri broadly rounded ; sides slightly widening to apical third ; disk with rows of 

 deeply impressed, coarse and closely placed punctures ; intervals narrow with a row 

 of irregularly placed finer punctures ; surface with rather abundant white and black 

 setae, the former more numerous and slightly shorter than the black. Underside of 

 body black, moderately clothed with erect white setse; prosternum, mesosternum and 

 sides of metasternum densely clothed with radiate-pectinate hairs. Legs black, 

 densely-clothed with erect and semi-erect white setse, intermixed with longer, black 

 setje ; femora armed with a large triangular tooth, front tibise slightly sinuate within, 

 the broadest part at about middle. Length 5.25 mm. 



Huachuca Mts., Arizona. 



In general form and size of the femoral tooth, this species is near- 

 est viyrmex Herbst, but the front tibiae are longer with the broadest 

 part medially, the thorax more closely and coarsely punctate and th
