the pygidium entirely covered and the body partially squamose 

 but not setulose. 



Hulpes n. gen. 



In this genus and the next the body is fairly large for the present 

 subfamily, elongate-oval, smooth, black and glabrous, excepting the 

 small subscutellar condensations of Hulpes. The beak here is 

 notably thick, compressed, strongly arcuate and strongly punctured, 

 separated from the head by an evident impression and with arcuate 

 decussate mandibles; the channel at the sides, beyond the antennae 

 is very deep and distinct. Antennae medial, with coarse and deep 

 scrobes, the scape not attaining the eye, the first funicular joint as 

 long as the next two, the second twice as long as wide, the following 

 subquadrate, gradually broader, the seventh as wide as the club, 

 which is broadly and obtusely oval and about as long as the three 

 preceding joints, its basal segment not quite half the length. The 

 prosternum is peculiar, being strongly tumid before the coxae; its 

 anterior slope is rapidly upward, and the canaliculation is broad, 

 sharply limited at the sides but extremely shallow, so that its 

 convex bottom along the middle attains the level of the side margins, 

 which flare posteriorly toward the coxae, these being large and 

 separated by rather more than their own width. The legs are well 

 developed, the femora subparallel, the middle and posterior feebly 

 dentate beneath, the terminal tibial spur very strong and the tarsi 

 long, with only feebly dilated rounded third joint, the claws moder- 

 ate and slender. The prothorax is tubulate at apex, the basal lobe 

 very small but narrowly rounded at tip, the scutellum free, trans- 

 verse, arcuate at base and truncate at apex, the elytra with the 

 rather fine grooves not exarate at apex, although coarser at tip, and 

 the pygidium relatively small and vertical. The type is the 

 following: 



Hulpes tumidipectus n. sp. — Elongate-oval, strongly convex, shining, smooth, 

 deep black throughout, completely glabrous, excepting in a small area of dense 

 narrow whitish squamules at the base of the third interval; beak (o 71 ) thick, 

 strongly and closely punctured, compressed, slightly alutaceous and a little longer 

 than the head and prothorax, the antennae blackish; prothorax slightly longer 

 than wide, the sides feebly converging, very evenly and moderately arcuate from 

 base to the tubulation, which is feebly medially sinuate and about half as wide 

 as the base; punctures fine, well separated, very gradually though moderately 

 coarse and subsimilarly separated toward the sides; elytra three-fifths longer 

 than wide, the feebly oblique sides slightly arcuate, rapidly obtuse at apex, the 

 humeri somewhat tumid, somewhat wider than the prothorax and two-thirds 

 longer, the grooves smooth and abrupt but scarcely a sixth as wide as the intervals, 

 which are very minutely, sparsely punctate along the middle; under surface 

 coarsely punctate, the femora and abdomen sparsely and less coarsely, the latter 

 broadly impressed medio-basally and with the first suture distinct throughout. 

 Length 7.6 mm.; width 3.18 mm. Mexico (Puebla). One specimen.
