disk convex anteriorly, broadly concave posteriorly, with a 
rather deep longitudinal depression inside of the angular 
carina on each side, reaching from the base to the middle of 
the length. Surface rather strongly punctate, sparsely 
clothed with long, white, semi-recumbent pubescence. 
Scutellum subtriangular, without transverse carina. 
Elytra nearly as wide at the shoulders as the middle of 
the pronotum, rather convex; sides arcuately constricted 
from the shoulders to basal third, expanded at posterior 
third, then arcuately attenuate to tips, which are separately 
rounded; the sutural angles rounded, without denticle; the 
sides of the elytra finely serrate at the shoulders and along 
the posterior third; surface finely granulate; each elytron 
with a shallow depression reaching from the base to the 
suture at basal fourth and another along the lateral margin 
behind the humerus. 
Chin piece straight in front, bordered by a little swelling, 
separated from the prosternum by a very deep and narrow 
groove. Prosternum convex, granulate. Inner posterior 
angles of the posterior coxae rounded. Abdomen finely punc-

pubescence. Disk of the last segment separated from the 
pleural margin by a deep and narrow groove; this groove 
curved inward onto the disk on each side, curving away from 
the basal angles of the segment. Lamellae of the tarsi yellow. 
A single specimen of this new species (type, M. C. Z. no.
