480 CASEY 



and broader, with the palpal foveas only just exposed, the last 

 palpal joint much larger, the ninth antennal joint differing but 

 little from the eighth, the combined and oval tenth and eleventh 

 joints relatively much larger, the abdominal excavation still 

 larger and with more depressed, even floor, and the elytral 

 tuberosities altogether different. The small shining tubercles 

 of the upper surface are much finer, and the surface is concealed 

 by a generally denser earthy indument, from which project 

 numerous longer, stiffer, recurved and squamiform hairs or 

 narrow scales, usually fulvous in color. The elytra have a 

 feeble lateral ridge from the humeri, terminating at the anterior 

 limit of the apical arcuation in a prominent marginal tuberosity, 

 somewhat as in Pkellopsis, and there is also a submedian ridge 

 on each elytron, terminating, at the summit of the apical decliv- 

 ity, in another prominent tuberosity. The type species before 

 me may be described as follows : — 



Body rather slender, parallel, depressed, black, clothed evenly and 

 rather closely with narrow recurved, subdecumbent and fulvous 

 scales, the surface between them largely concealed by earthy in- 

 dument ; head with the long oblique sutures distinct, gradually ele- 

 vated laterally, nearly smooth and dull but with some scattered 

 black granules ; prothorax not quite as long as wide, the sides 

 parallel and nearly straight, arcuately converging anteriorly to the 

 rounded apical angles, abruptly and rather strongly converging 

 and almost straight in basal third, becoming feebly sinuate before 

 the basal angles, which are right and slightly prominent, the base 

 feebly arcuate, closely applied to the base of the elytra ; surface 

 feebly elevated and broadly convex along the middle, except toward 

 apex, and with two impressions at each side of the ridge, the four 

 forming a central square, also more feebly impressed in the mid- 

 dle toward the sides and toward the basal angles, the black tuber- 

 cles small, evenly distributed and moderately sparse ; elytra a little 

 wider than the prothorax and three-fourths longer, the humeri 

 rather prominent but broadly, obliquely rounded, the sides behind 

 them sinuate for a short distance, then parallel and feebly arcuate 

 to the strong subapical tuberosity, parabolic apically, feebly sinu- 

 ate at the suture ; surface with a few rows of very coarse but in- 

 distinct, moderately impressed and irregularly rounded fovete, each 

 elytron with a median ridge fi'om the base to apical fourth, where 

 it ends abruptly in a more pronounced tuberosity and a short 

 ridge from the base to basal fifth or sixth, between the princi- 

 pal ridge and the feebly elevated suture, the polished black tuber- 

 cles very fine and remotely scattered ; under surface with short, 

 coarse, sparse hairs and numerous small tubercles, which are a
