Eyes much less distant, separated by about one-half more than their 

 own width; vertex convex, more shining, very minutely and sparsely 



punctate; body verj^ small and narrow 4. vigilaiis 



Eyes large, convex and very coarsely faceted ; antenna? much more approx- 

 imate in insertion; elytra very densely clothed with extremely minute 

 appressed pubescence giving a strongly opaque or pruinose effect, the 

 punctures bearing each a longer stiffer hair, which is however still 

 minute and subdecumbent; subbasal impressions of the pronotum 

 feeble and completely separated. (Ill) 

 Antenna) filiform, just visibly and evenly incrassate throughout the 

 length. 

 Antenna) decidedly thick; basal impressions of the pronotum large and 



distinct ;"). liiiroiiicil^ 



Antenna) slender; ba.sal impressions almost completely obsolete. 



6. sagax 



Antenna) much shorter, rapidly and strongly incrassate toward apex, the 



penultimate joints strongly transverse; basal impressions of the jjro- 



uotum feeble 7. floridaiilis 



Eyes smaller and only moderately coarselj^ faceted, the tempora relatively 

 long, parallel and distinct behind them; antenna) longer, inserted at some 

 distance from the eyes and moderately separated at base; impressions of the 

 pronotum and vestiture nearly as in t\\Q piceus group. (IV) 8. wickliailli 



All but one of these species are represented before me by a 

 single specimen, and the extent of the genus will be greatl}^ in- 

 creased by future collecting. These species are, however, widely 

 distinct among themselves, and the limited number of examples 

 is, for this reason, a matter of but little consequence. 



1. V. calvesceiis n. sp. — Oblong-elongate, feebly convex, moderately 

 shining, blackish-castaneous throughout; vestiture extremely short, sparse 

 and rather coarse, closely decumbent. Head strongly transvei'se, finely retic- 

 ulate, more obsoletely toward the median line, finely, strongly, not densely 

 punctate, the eyes large, globular, separated by three-fourths more than their 

 own width; antennae somewhat stout, feebly and gradually incrassate through- 

 out, about one-third as long as the body, the tenth joint slightly transverse, 

 the eleventh conoidal, not as long as the two preceding. Prothorax distinctly 

 narrower than the liead, obliquely narrowed in apical third, about one-fourth 

 mder than long; apex arcuate and much narrower than the base; disk feebly 

 convex, polished, not reticulate, rather finely, deeply but not densely punc- 

 tate, broadly, feebly impressed transversely near the base, the impression con- 

 tinuous. Scutellum as wide as long, trapezoidal, rather tumid. Elytra fully 

 three-fourths longer than wide, twice as wide as the prothorax, parallel and 

 very feebly arcuate at the sides; apex broadly and obtusely rounded; humeri 

 broadly rounded to the prothorax; disk with a large impression at basal third, 

 extending obliquely within the humeri, also impressed on each side of the 

 suture behind the scutellum, ami feebly at apical fiftli, the omoi)lates large;
