widely separated posteriorly, rather sparsely clothed with long, 
recumbent, dark and light yellow hairs intermixed; intervals obso- 
letely granulated ; epistoma rather wide between the antennal cay- 
ities, flat and not transversely carinate in front. Pronotum 
moderately convex, two times as wide as long at middle, dis- 
tinctly narrower in front than behind, widest at base; sides 
obliquely attenuate from base to anterior angles; anterior 
margin nearly truncate; base transversely truncate to middle of 
elytron, then turning obliquely backward to the scutellum, in front 
of which it is arcuately emarginate; posterior angles rounded ; sur- 
face broadly depressed at the sides, the depression extending obliquely 
from the anterior angles to the base at middle of elytron, then trans- 
versely along the base, causing the anterior median part of the disk 
to be regularly convex, there is a distinct straight carina on each side 
in the depressed area, which does not reach the base nor anterior 
margin, finely and sparsely punctate on the disk, with large, round, 
shallow punctures in the depressed areas, sparsely clothed with long, 
recumbent, cinereous hairs (with a few fulvous ones here and there) 
leaving two round, approximate bare spots on the disk, and with 
two small spots of denser pubescence at the base, close to the scu- 
tellum ; intervals obsoletely granulated. Scutellum nearly smooth, 
broadly triangular, anterior margin rounded. LElytra nearly as wide 
as pronotum at base; humeral angles obtusely angulated; sides 
nearly parallel to the middle (strongly sinuate at basal fourth), then 
obliquely attenuate to the tips, which are conjointly broadly rounded, 
with the lateral margins entire; humeri prominent. LEach elytron 
with a broad, shallow depression at the base, and a deeper one behind 
the humerus between the lateral carina and lateral margin, with a 
distinct lateral carina, which is sinuate and strongly elevated at the 
humerus, broadly depressed at basal third, and extending from the 
humeral angle to the apex, with four fine lines of fulvous hairs 
extending from the base to the middle, one along the suture, two on 
the disk, and the fourth along the lateral carina; basal half nearly 
glabrous, with a few fulvous hairs between the third pubescent line 
and the lateral margin and the space near the scutellum (between 
the suture and second pubescent line) sparsely clothed with fulvous 
pubescence ; at a short distance behind the base, between the second 
and third pubescent lines, there is a small spot of cinereous hairs ; 
at the middle there is a well-marked, moderately broad fascia of 
recumbent, cinereous pubescence, inclosing a small patch of fulvous 
hairs, and extending from the second to the fourth pubescent line ; 
at the posterior margin of this fascia there are two small patches of 
cinereous hairs, one near the lateral margin and the other close to 
the suture; behind the median fascia there is a transverse space 
with a few recumbent, black hairs; the apex is covered with recum-
