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

 strongly convex, black, tlie legs pale testaceous, the femora infuscate abo\e to- 

 ward apex; antennse xmle, 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; scutellum covered with a dense 

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

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

 the prothorax, fully as wide as long, flat, o1)scurely 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; antennae rather long and slender, much 

 longer than the prothorax, the joints oblique at apex, fifth elongate and slightly 

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

 sixth and eightli slightly smaller. Profhord.c two-fifths wider than long, not 

 constricted, widest and subprominently 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 l)eing acixte, everted and minutely prominent; apex arcu- 

 ato-truncate, narrower than the Ijase 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 feeldy arcuate, 

 obliquely 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 siirface densely clothed with de- 

 cumbent white puliescence, whicli is especially dense on the met-ej)isterna

New Mexico. 



The fifth ventral segment in the single tj'pe before me is 

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

 identified b\' its elongate el3"tra, variegated vestiture and thoracic 

 structure. 



MECOIWYCTER 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 epipleuraj are subhori- 

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

 dle, and the genus farther ditl'ers 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, and in the complete
