the tips, which are separately, rather broadly, obliquely rounded, 

 and not serrulate; sides of abdomen broadly exposed above; disk 

 feebly depressed along suture, a vague costa on each side, and with 

 broad, shallow, basal depressions; surface indistinctly imbricate- 

 pimctate and granulose, each elytron ornated with silvery white 

 pubescent designs as follows ; a small patch in basal depression, an 

 oblique band behind this at suture, a longitudinal band along suture, 

 extending to near the middle, bending obliquely outward and back- 

 ward (sometimes divided), and the apical third entirely pubescent, 

 the anterior margin of area extending obliquely backward from the 

 suture at middle to lateral margin near apical third. 



Abdomen beneath densely, finely granulose, sparsely punctate, the 

 punctures denser and connected transversely by sinuate lines at sides 

 of basal segments, sparsely clothed with short, inconspicuous hairs, 

 and with a feeble pubescent spot at sides of third segment; first seg- 

 ment feebly convex, without a median groove; last segment broadly 

 rounded at apex ; vertical portions of first and second segments 

 densely pubescent; pygidium finely, sparsely punctate, and dis- 

 tinctly carinate, but the carina not projecting. Prosternum densely 

 granulose, sparsely punctate, and clothed with a few short recumbent, 

 white hairs; prosternal lobe, broad, feebly declivous, and with a 

 deep, semicircular emargination in front ; prosternal process broad, 

 the sides feebly expanded behind the coxal cavities, and obtusely an- 

 gulated at apex. Sides of metasternum and mesosternum densely 

 pubescent and efflorescent. Tibiae slender, straight, and without a 

 distinct tooth on inner margin at apex. Posterior tarsi distinctly 

 shorter than the tibiae, and the first joint about as long as the fol- 

 lowing two joints united. Tarsal claws similar on all feet, cleft near 

 middle, the inner tooth broad, much shorter than outer one. and not 

 turned inward. 



Length, 3.75 mm. ; width, 1.12 mm. 



Male. — Differs from the female in having the head bright green 

 in front, becoming brownish black on the occiput, front rather narrow, 

 slightly wider at bottom than at top, the lateral margins feebly 

 narrowed from bottom to vertex, and the surface densely clothed 

 with long, recumbent, silvery white hairs behind the epistoma; an- 

 tennae with the outer joints about as long as wide; abdomen more 

 narrowly exposed above ; legs bronzy green on the ventral side, and 

 the anterior and middle tibiae armed with a small tooth on inner 

 margin at apex; tarsal claws dissimilar, anterior claws cleft near 

 the tip, and the teeth nearly equal in length, the middle and posterior 

 claws cleft near the middle, the inner tooth broad, much shorter 

 than outer one, and not turned inward.
