Length 5-7.5 mm., width 1.5-2.5 mm. 



Type locality. — Santa Rita" Mountains, Ariz. 



Type and paratypes. — In the United States National Museum, No. 

 58313. 



Described from five specimens (one type). The type and two 

 paratypes were collected at the type locality, June 19, by E. A. 

 Schwarz; and two paratypes from the Brooklyn Museum Collection 

 were taken in the Huachuca Mountains, Ariz., probably by Charles 

 Schaeffer. These are probably all females. 



This species resembles small specimens of bicornis Weber, but it 

 differs from that species in having the antenna with only nine seg- 

 ments, the pronotum convex in front of the scutellum, the elytra 

 truncate at base and without longitundinal costae, and the dorsal sur- 

 face of the body irregularly clothed with short, yellowish hairs.

Male. — Elongate, cylindrical, dark reddish brown, palpi, antennae, 

 and tarsi sometimes slightly paler ; dorsal surface of body irregularly 

 clothed with small, oblong, yellowish- white scales, which are not more 

 than twice as long as wide. 



Head much narrower than pronotum, more or less rugose, sparsely, 

 coarsely tuberculose; clypeus flat; clypeal suture distinct; labrum 

 densely ciliate with long yellowish hairs in front. Antenna 10-seg- 

 mented; third segment slightly elongate, fourth to seventh round or 

 slightly transverse. 



Pronotum quadrate, widest near middle, strongly deflexed on apical 

 half, with two unciform processes in front ; without a depression but 

 with two small gibbosities in front of scutellum; sides broadly 

 rounded, more strongly converging anteriorly, posterior angles rec- 

 tangular ; surface with a narrow, longitudinal, median groove on basal 

 half, densely, irregularly granulose, the tubercles small and round 

 on basal half, becoming larger, broader, and rasplike on apical half. 



Elytra at base subequal in width to pronotum at middle, tuberculate 

 at base, each elytron with two crenulate, longitudinal costae, the 

 inner costa strongly elevated and extending from base to apical de- 

 clivity, the outer costa usually only indicated posteriorly ; sides par- 

 allel, conjointly angularly emarginate at apices, with a small, acute 

 spine on each side of emargination ; surface coarsely, deeply, irregu- 

 larly punctate, more or less rugose, with numerous small, round, pol- 

 ished tubercles, the scales denser in places giving the surface a 

 variegated appearance.
