Baring 435 



than the prothorax, somewhat more than twice as long, the sides feebly 

 oblique to the broadly and circularly rounded apex; striae moderate, the 

 intervals somewhat convex, coarsely, rugulosely but not densely punc- 

 tate, four to five times as wide as the striae; abdomen with a small carini- 

 form tubercle medially at base. Length (cf) 4.65-4.9 mm.; width 

 1.8-2.0 mm. Mexico (Cuernavaca), — Wickham. Two examples. 



Easily recognizable by the subglabrous and shining upper surface, 

 rather coarse sculpture, elongate-oval, convex form and other 

 characters as noted. 



*Odontocorynus vernicicoUis n. sp. — Elongate, subrhomboid-ovaU 

 moderately convex, deep black throughout, shining; vestiture very 

 nearly as in the preceding; beak in the male nearly as in the preceding 

 but as long as the head and prothorax, deeply sulcate at the sides, the 

 antennae inserted at three-fifths, the three outer funicular joints rapidly 

 very transverse and perfoliate, the club large and subglobose, pointed 

 apically, without distinct basal tooth; prothorax only a fifth or sixth 

 wider than long, the sides evenly converging, evenly and moderately 

 arcuate throughout to the apical constriction; apex evidently less than 

 half as wide as the base, the lateral denticle acute and prominent; 

 punctures much smaller than in the preceding, widely separated medially, 

 rugosely confluent only at the extreme sides, having, near each side just 

 behind the middle, a small irregular smooth spot; median line broadly 

 impunctate but centrally only; elytra not quite one-half longer than 

 wide, at the notably prominent humeri much wider than the prothorax 

 and twice as long, or a little more, the sides more oblique and arcuate 

 than in limatuliis, the apex relatively somewhat more narrowly rounded; 

 striae slightly coarser; intervals feebly convex, with strong and confused, 

 well spaced punctures, which are regularly circular, very close toward 

 base of the fifth, alternating perceptibly in width, two to three times as 

 wide as the striae; abdomen with a rounded smooth spot not quite basal 

 on the first segment, the centre of which has a very small cariniform 

 tubercle. Length (cf) 5.7-6.2 mm.; width 2.3-2.65 mm. Mexico 

 (Puebla). Two specimens. 



Allied to Umatulus but differing in its larger size, more elongate 

 and polished, less coarsely and more sparsely punctured prothorax, 

 with relatively narrower apex, basally broader elytra, with coarser 

 striae, and in the antennal club, as may be inferred above. 



*Odontocorynus subvittatus n. sp. — Slender, moderately convex, with 

 narrowed prothorax, black throughout; pronotum with very fine sparse 

 hair-like squamules, barely discernible, the basal lobe sparsely, the 

 scutellum densely, albido-squamulose, the elytra with whitish squamules, 

 fine and hair-like, sparse and indistinct but close-set and conspicuous on 

 the first, third and fifth intervals; under surface with the white squamules 

 coarser, abundant and distinct though not dense; beak in the male 

 evenly cylindric, feebly, evenly arcuate, densely sculptured and as long
