28 PKOCEEDINGS OP THE NATIONAL MUSEUM vol.82 



Pronotum slightly wider than long, wider at apex than at base, 

 and widest in front of middle; sides arcuately rounded anteriorly, 

 obliquely narrowed posteriorly to the posterior angles, which are 

 rectangular; when viewed from the side the marginal and sub- 

 marginal carinae feebly sinuate, rather widely separated for their 

 entire length; anterior margin strongly sinuate, with the median 

 lobe very strongly produced and broadly rounded; base vaguely, 

 broadly, arcuately emarginate on each side, with the median lobe 

 slightly produced and broadly rounded; disk strongly convex ante- 

 riorly, broadly, transversely concave on basal half, the concavity ex- 

 tending obliquely forward on each side to the apical angle; surface 

 feebly, coarsely, irregularly rugose, the rugae more or less transverse 

 at the middle and oblique toward the sides, sparsely, finely punc- 

 tate between the rugae, sparsely clothed toward the sides with short, 

 white hairs. Scutellum strongly, transversely carinate, the surface 

 densely, finely reticulate. 



Elytra slightly wider than pronotum at base, and at base slightly 

 wider than behind middle; sides arcuately rounded behind base, 

 broadly, arcuately constricted in front of middle, broadly, arcuately 

 expanded behind middle, then obliquely narrowed to the tips, which 

 are separately broadly rounded or subtruncate, and finely serrulate ; 

 sides of abdomen narrowly exposed above; disk feebly flattened, 

 without distinct longitudinal costae, the sutural margins slightly 

 elevated posteriorly, and with broad, shallow, basal depressions; 

 surface densely, coarsely imbricate-punctate on basal halves, more 

 feebly punctate on apical halves, each elytron ornamented with 

 short, recumbent, white pubescence as follows: A small spot in 

 basal depression ; a small, round, spot along sutural margin at basal 

 third; a narrow fascia extending obliquely backward from sutural 

 margin at middle to lateral margin behind middle; and a large, 

 subtriangular spot covering the apical third, enclosing an oblong, 

 glabrous spot along sutural margin. 



Abdomen beneath sparsely marked with transverse, crenulate lines, 

 which are coarser on the basal segment, sparsely, finely punctate, 

 sparsely clothed with short, inconspicuous hairs, and with a large 

 spot of recumbent, white pubescence on each side of third segment ; 

 first segment strongly convex at middle, the suture between first and 

 second segments not indicated at the sides; last segment broadly 

 subtruncate or feebly emarginate at apex; vertical portions of the 

 segments not conspicuously pubescent, except the first, which is orna- 

 mented with a white pubescent spot; pygidium densely granulose, 

 vaguely punctate, without a projecting carina at apex. Prosternum 

 feebly granulose, finely, sparsely punctate, sparsely clothed with 

 long, erect, white hairs; prosternal lobe broad, strongly declivous, 

 broadly subtruncate or broadly, vaguely emarginate in front; pro-
