8. Prothorax very densely punctured; scales yellowish. . . 2O. falsus. 



" less " " 8'. 



8'. Pubescence white, scale-like canus. 



yellowish, fine and capillary 21. longulus. 



20-21. Oentrinus canus, n. sp. 



Elongate, rather depressed, black, shining, tolerably densely clothed 

 with small, whitish scales. Bjakas long as the head and prothorax, slender, 

 slightly curved, smooth and polished, punctured only at the base. Head 

 finely punctured, frontal impression distinct. Prothorax scarcely longer 

 than wide, gradually slightly narrowed from the base for more than half 

 the length, then rounded, and more suddenly narrowed to the tip, where 

 it is feebly constricted ; strongly and rather densely, but not confluently 

 punctured, with a narrow, smooth dorsal line. Elytra a little wider near the 

 base, then very slightly narrowed ; conjointly rounded at tip, striae deep, 

 interspaces flat, rugosely punctulate, wilh the scales not arranged in rows. 

 Prosternum transversely impressed as usual, and longitudinally concave ; 

 apical part with a small fovea ; hind margin not emarginate ; front coxae 

 widely separated ; fifth ventral segment longer than the fourth. Funicle of 

 antennae slender ; first joint as long as the second and third united ; second 

 twice as long as the third. Length 4.7 mm. ; .18 inch.

2. Centrinus strigatus, n. sp. 



Elongate, parallel, brownish black, thinly pubescent with yellowish 

 hairs. Beak cylindrical, rather slender, curved, as long as the head and 

 prothorax, dark brown, shining, sparsely and finely punctured. Head 

 sparsely punctulate. Prothorax scarcely wider than long ; sides nearly 

 parallel for half the length, then rounded and obliquely narrowed to the 

 tip, which is strongly constricted ; surface deeply, coarsely and confluently 

 punctured ; the intervals between the punctures form longitudinal plicae, 

 as in Onychobaris rugicollis, but finer; medial line smoothly elevated, ex- 

 tending nearly to the tip and base. Elytra not at all wider than the bas3 

 of the prothorax, parallel on Ihe sides for two-thirds the length, then ob- 

 liquely narrowed to the tips, which are very broadly conjointly rounded, 

 and seem almost truncate, though the pygidium is entirely concealed ; stria? 

 deep, finely punctured ; interspaces a little wider than the stria 1 , with single 

 rows of deep punctures, which bear small, reclinate yellow hairs. Beneath 

 strongly punctured. Prosternum deeply, transversely impressed, not fin-f- 

 ate ; front coxae widely separated ; metathoracic episterna narrower than
