club is notably smaller than in the male, and the funicle is longer 

 and more slender, but aside from the shorter beak of the male I do 

 not observe any other sexual differences.

Oblong-oval, subdepressed, alutaceous, black throughout, the 

 antennae slightly paler ; integuments subglabrous, the vestiture 

 consisting of very small fine white squamules, sparsely disposed 

 above and beneath. Beak in the male rather stout, cylindrical, 

 finely, densely punctured and squamulose toward base, straight in 

 basal two-thirds, then bent, scarcely more than three-fourths as long 

 as the prothorax, the antennae inserted distinctly beyond the middle, 

 the basal joint of the funicle robust, not as long as the next three, 

 the second small, obconical, one-half longer than wide, the club 

 moderately stout, oval, densely pubescent and nearly as long as 

 the preceding five joints combined. Prothorax slightly wider than 

 long, sides parallel and feebly arcuate, rounded convergent and con- 

 stricted toward apex, the latter one-half as wide as the base ; punc- 

 tures fine, not very close-set, the impunctate line distinct. Elytra 

 a little wider and three-fourths longer than the prothorax, hemi- 

 elliptical, the humeral callus large but feeble ; striae fine, the inter- 

 vals flat, wide, finely and more or less confusedly punctate. Pro- 

 sternum separating the coxae by two-thirds of their own width or 

 less, with two slender slightly contorted ante-coxal spiniform pro- 

 cesses, which are very oblique, and immediately before which there 

 is a large deep excavation. In the female the beak is more slender, 

 more evenly and distinctly arcuate, smooth, polished and evidently 

 punctured only near the base, not longer than in the male, being 

 about three- fourths as long as the prothorax ; the prosternum is flat 

 and the intercoxal process is not noticeably wider than in the male. 

 Length 2.7-3.5 mm.; width 1.1-1.5 mm. 



In the description of Boheman, the beak is said to be as long as 

 the prothorax in the italicized diagnosis, but as long as the head 

 and prothorax in the description which follows, the fact being, if I 

 have correctly identified the species, that it is much shorter than 

 the prothorax in both sexes. In the description referred to I cannot 

 comprehend the allusion toa " pygidium."
