the antennse abruptly very strongly inflated, thick, densely punctured and 

 squamose, with a smooth median line; antennse inserted at basal third, the 

 scape very short, but slightly longer than the basal joint of the funicle, the 

 latter nearly as long as the next three, the second slightly longer than the 

 third, both elongate, joints three to six longer than wide, club oval, abrupt, 

 densely pubescent, almost equally trilobed by the distinct sutures and one- 

 half as long as funicular joints two to seven. Prnthorax rather short, three- 

 fourths wider than long, the sides broadly, strongly arcuate anteriorly, be- 

 coming nearly parallel in basal half and rather strongly sinuate behind the 

 apex, which is truncate and one-half as wide as the base, the latter trans- 

 verse, the median lobe prominent and equalling one-third of the total width ; 

 disk somewhat coarsely, deeply and very densely punctured, without distinct 

 impunctate line, the vestiture covering the entire surface. Scutellum densely 

 squamose. Elytra quite distinctly wider than the prothorax and a little more 

 than twice as long ; sides strongly convergent and feebly arcuate throughout, 

 the apex narrowly rounded; humeral callus strong and prominent; mes- 

 epiraera not visible from above ; strias rather fine, deep, the intervals wide, 

 rather coarsely, deeply, confusedly, very densely and rngosely punctured. 

 Abdomen strongly convex toward base, strongly inclined upward toward apex. 

 Prostei'num nearly flat, very densely squamose, the eoxse separated by three- 

 fourths of their own width. Length 3.5 mm. ; width 1.7 mm.

I have only seen the female, and the remarkable form of the beak, 

 reminding us strongly of Eunyssobia (Euehaetes Lee), is probably 

 peculiar to that sex, as it may be observed to a less degree in several 

 other species of this subgenus, and notably grisescens ; at any rate, 

 the peculiar basal enlargement is much more developed in the female 

 than in the male of that species. 



13 CentrinilS claresceilS n. sp. — Rather narrowly ovoidal, convex, 

 pale rufo-testaceous throughout, the scutellum, head and beak rather darker 

 and piceous ; vestiture consisting of rather large, moderately elongate, ochre- 

 ous-yellow scales, rather dense and uniformly distributed above, very dense 

 and broader beneath. Head alutaceous, completely glabrous, exceedingly 

 minutely and sparsely punctate ; impression completely obsolete, with an 

 elongate median fovea ; beak in the male slender, strongly, evenly arcuate, 

 gradually and but slightly thicker toward base, distinctly punctured and 

 sparsely squamose at the sides behind the antennje, shining, polished and 

 almost impunctate elsewhere, dilated at apex and at the point of antennal 

 insertion, and very nearly one-half as long as the body ; antennse slender, 

 inserted just behind the middle, the first two joints of the funicle equal in 

 length, the second much the more slender and fully as long as the next two, 

 seventh slightly longer than wide and a little thicker than the preceding, 

 club oval, abrupt, but slightly longer than the three preceding joints com- 

 bined. Prothorax about one-half wider than long, the sides broadly, evenly
