flat, dilated at apex ; surface with three narrow, deep, and abrupt 

 canaliculations, the median beginning at the middle and terminating at 

 the transverse impression, the lateral beginning at the basal third, 

 continuing parallel with the median to the transverse impression and 

 then turning abruptly outward and downward to the anterior margin 

 of the eye ; apex truncate and feebly trisinuate ; surface of head and 

 beak finely punctate, each puncture bearing a very small seta. Pro- 

 thorax cylindrical, one-third wider than long, slightly wider than the 

 head ; sides very feebly, nearly evenly arcuate ; base and apex 

 transversely truncate, nearly equal ; surface very coarsely, deeply, and 

 densely punctate, the fine setae arising from fine punctures irregularly 

 scattered over the convex interspaces of the large foyeae. Scutellum 

 distinct, white. Elytra elongate-oval, nearly three-fourths longer than 

 wide ; sides very feebly arcuate ; humeri broadly rounded ; disk one- 

 half wider than the prothorax, at base equal to the latter, broadly 

 sinuate ; basal margin elevated ; striae feebly impressed, coarsely, 

 deeply, but not very closely punctate ; intervals nearly flat, each with a 

 row of long stiff spinous setae. Legs and abdomen with fine sparse 

 setae. Length 4.0-4.6 mm.

The anterior tibiae have a few small denticles along the inner 

 edge toward apex. 



RHIOOPSIS Lee. 



R. §cntellata n. sp. — Form oval, slightly depressed above, densely 

 clothed throughout with very large, closely adherent, and slightly over- 

 lapping scales, which are white and blackish intermingled, the former 

 greatly predominating, not at all concealed by exudation. Head and 

 beak distinctly longer than the prothorax ; beak deeply trisulcate, the 

 middle sulcus continuing uninterrupted to the base of the head, the 

 lateral abruptly ending at the front and attenuated anteriorly ; 

 prominences over the eyes moderate, the front between them scarcely 

 at all concave. Prothorax one-third wider than long, widest at 

 anterior fourth where the sides are distinctly arcuate, thence slightly 

 convergent and nearly straight to the base ; the latter broadly arcuate 

 and about as wide as the apex ; the latter truncate between the 

 advanced and prominent ocular lobes : disk convex transversely, 

 arcuately impressed near the apex, with a broad, deeply impressed 

 median line, interrupted near the middle, the basal fovea being the 

 longer; surface coarsely ruguloso-foveolate. Scutellum rounded, 

 convex, distinct. Elytra oblong, less than one-half longer than wide, 

 slightly produced at apex ; the latter truncate ; sides parallel and 

 slightly arcuate ; humeri oblique, slightly prominent posteriorly ; disk 

 three-fourths wider than the prothorax ; each elytron with three 

 prominent ridges, the two inner terminating in abrupt and moderate
