unevenly arranged on the elytra and erect and bristling on the head ; color 

 pale rufo-testaceous ; head and beak blackish, the tip of the latter pale ; 

 elytra with a broad triangular basal area and an elongate narrow subsutural 

 spot behind the middle of each blackish ; sterna and side-pieces black. Head 

 very densely punctate, without distinct frontal fovea ; beak short, stout, just 

 visibly bent, rather finely, deeply and moderately densely punctate but not 

 at a.11 sulcate or carinulate, in the male barely longer than the prothorax, 

 with the antennae inserted at apical third ; basal joint of the antennal funicle 

 fully as long as the next three, club moderate, not at all darker in color, with 

 the first joint subglabrous toward base. Prothorax short, two-thirds wider than 

 long ; sides parallel and nearly straight in middle two-thirds, convergent and 

 rounded near the base, convergent and very feebly sinuate behind the apex, 

 the latter three-fourths as wide as the base ; punctures very dense, rather 

 fine, deep ; median line very narrowly and feebly carinulate. Elytra at base 

 fully one-third wider than the prothorax, nearly four times as long, parallel 

 and straight at the sides, ogival in apical third, the sutural notch subobsolete ; 

 striae barely impressed, coarsely deeply and closely punctate, the intervals not 

 quite twice as wide as the striae, finely, rather sparsely and confusedly punc- 

 tate. Abdomen rather strongly punctate, blackish toward base and in the 

 median parts of the fifth segment. Leys short ; femoral teeth rather large and 

 distinct but acute. Length 3.0 mm. ; width 1.2 mm.

A small narrowly convex species of peculiar coloration, with long 

 coarse and sparse but conspicuous vestiture, and short non-sulcate 

 beak. It is not closely allied to any other form which I have seen.

Oblong, subcuneiform, moderately convex, polished, rufo-testace- 

 ous, the head piceous ; vestiture rather sparse, consisting of short 

 robust recumbent pale hairs, confusedly condensed and mottled on 

 the elytra, longer and more slender on the pronotum ; erect setae 

 entirely wanting. Head rather coarsely, strongly punctate, the 

 fovea very small ; beak not very stout, almost straight, deeply, 

 coarsely punctured in longitudinal furrows, evenly and just visibly 

 arcuate in the female, straight and slightly bent near the apex in 

 the male ; in the male it is a little less than one-half as long as the 

 elytra, with the antennae inserted at apical third, the first funicular 

 joint but little longer than the next two, in the female barely one- 

 half as long as the elytra, the antennae inserted just behind apical 

 third, with the basal joint of the funicle fully as long as the next 

 three. Prothorax small in both sexes, nearly one-half wider than 

 long, rather coarsely, closely punctate, with a narrow imperfect im-
