1. Li. adspersa n. sp. — Elongate, narrowly oval and not broader behind, 

 strongly convex, black, the legs pale testaceous, the femora infuscate above to- 

 ward apex; antennte pale, dark near the tip; pubescence moderately dense, 

 composed of closely appressed and rather long broad hairs, which are white 

 and dark brown in color confusedly intermingled throughout, becoming denser 

 and white near the sides and along the base of the pronotum, and altogether 

 white though scarcely denser on the head; soutellum covered with a dense 

 mass of white pubescence; marginal fringe composed of very short, dense and 

 coarse, posteriorly subdecumbent brown hairs. Head two-thirds as wide as 

 the jDrothorax, fully as wide as long, flat, obscurely and finely punctate, the 

 impressions apical and feeble; epistoma pale and well developed, the labrum 

 pale, broadly rounded at apex ; eyes small, prominent, at some distance from 

 the base, the neck slightly constricted; antennse rather long and slender, much 

 longer than the prothorax, the joints ol)lique at apex, fifth elongate and slightly 

 dilated, the three last slightly larger, the penultimate nearly as long as wide, 

 sixth and eighth slightly smaller. Prothorax two-fifths wider than long, not 

 constricted, widest and subi)rominentIy rounded just behind the middle, the 

 sides strongly convergent and straight to the apical angles, which are obtuse 

 but not blunt from above, and almost equally convergent and straight to the 

 basal angles, these being acute, everted and minutely prominent; apex arcu- 

 ato-truncate, narrower than the base which is broadly and arcuately lobed; 

 disk finely, rather closely punctate, the submarginal groove very coarsely ex- 

 cavated, extending almost to the apex and curving inward near the base, be- 

 coming obsolete toward the middle. Elytra elongate, nearly twice as long as 

 wide, slightly wider than the prothorax, the sides parallel and feebly arcuate, 

 obli(juely convergent and arcuate at apex, the immediate tip rather narrowly 

 obtuse; sutural angles acute; punctures fine and moderately close, not very 

 distinct; margins not at all reflexed. Under surface densely clothed with de- 

 cumbent white pubescence, which is especially dense on the met-episterna 

 and abdomen; legs rather stout. Length 3.0 mm. ; width 1.0 mm. 



New^ Mexico. 



The fifth ventral segment in the single type before me is 

 strongly rounded at apex. This striking species can be at once 

 identified by its elongate elytra, variegated vestiture and thoracic 

 structure. 



MECOMYCTER Horn. 



In this genus the ungual appendages become completel}^ obso- 

 lete, the claws being at the same time unusually slender and with 

 a small internal enlargement at base. The epipleurre are subhori- 

 zontal and moderate in width, becoming extinct behind the mid- 

 dle, and the genus further difiers from the members of the Allonyx 

 group, which it resembles to some extent, in having all the tibiae 

 beset externally with a few blackish spinules,aud in the complete
