short, yellow, recumbent hair and with a small median smooth 
area ; eyes with the inner side strongly margined ; epistoma wide, 
elevated, anterior margin widely, arcuately emarginate, the 
angles acute and extending under base of antennae, which 
are widely separated; clypeal suture distinct. Pronotum short, 
about four times as wide as long, narrower in front than behind ; 
surface densely marked with circles, similar to that of the head, 
densely clothed with white, yellow, and reddish brown recum-

emarginate, with the angles acute; sides oblique and slightly 
arcuate; base bisinuate, with a broadly rounded median lobe in

wide as pronotum at base, gradually attenuate to the posterior 
third, then arcuate to the tips, which are conjointly, broadly 
rounded; humeri not very prominent; surface without lateral 
carina, densely punctate and rather strongly rugose, broadly 
depressed albng base near humeri, and densely clothed with short 
white, yellow, and dark brown recumbent pubescence, forming 
irregular designs, the designs becoming more transversely 
zigzag toward the apex, with a distinctly marked inverted W, 
composed of white pubescence just in front of apex. Beneath 
convex; abdomen coarsely and densely marked with semicir- 
cular lines, in the middle of which is a small puncture, finely 
granulate and sparsely clothed with distinct whitish recumbent

part bent downward, with the front margin broadly arcuate and 
distinctly margined; intercoxal process transverse, flat, nar-
