pieeo-castaneoiis; femora piceo-castaneoiis, tibias and tarsi paler, brownisli- 

 riifons; autenure piceous at base, becoming fuscous in the middle and pale 

 testaceous at tip; palpi fuscous; integuments polished, very feebly sub- 

 alutaceous; pubescence anteriorly very sparse, that of the elytra coarse, not 

 very dense, that of the abdomen more than twice as dense, sericeous, fulvous 

 and conspicuous. Head moderate, as long as wide; base broadly and very 

 feebly arcuate, angles rather broadly rounded; sides parallel and extremely 

 feebly arcuate; epistoma rather strongly produced, broad, truncate at tip; 

 antennal tuberculatiotis small, rather prominent; surface rather finely and 

 moderately densely punctate; median line narrow, continuous throughout; 

 antennas slightly shorter than the head and prothorax together; second joint 

 distiuctb^ shorter than the third, very slightly longer than the fourth. 

 ProthordX large, just visibly wider than the head, slightly wider than long; 

 sides parallel, extremely feebly arcuate; base broadly, evenly and rather 

 strongly arcuate; apex broadly and very feebly so; nuchal emargination one- 

 third as wide as the disk, very feeble; apical angles rather narrowly rounded, 

 basal broadly so; disk transversely, nearly evenly and rather feebly convex, 

 finely, very feebly and rather sparsely punctate in the middle, slightly more 

 densel}' so at the sides; median impunctate area broad, equal, narrowly, very 

 feebly and longitudinally impressed near the base. Elytra at base distinctly 

 wider than the pronotum; sides very slightly divergent posteriorly and 

 slightly arcuate, together broadly and rather strongly sinuate behind; disk 

 feebly convex, narrowly impressed along the slightly elevated suture, more 

 strongly so at one-third the length from the apex, finely, deeply, sub-aspe- 

 rately, evenly and rather densely punctate; slightly longer than wdde, and 

 less than one-third longer than the pronotum. Abdomen rather short and 

 broad, as wide as the elytra; sides parallel and distinctly arcuate; surface 

 minutely very densely and sub-asperately punctate. Legs slender; first 

 joint of the posterior tarsi one-third longer than the second, nearly as long as 

 the third and fourth together. Length 4.2 mm.

This species may be distinguished from the preceding by 

 its shorter and more coarsely and sparsely punctured elytra, 

 its much longer and more evenly punctate pronotum, and 

 especially by its different coloration. 



18 — L. COntigUUa ri- sp- — Form rather slender, rather strongly convex; head, 

 pronotum and abdomen black, the latter very slightly paler at tip; elytra pice- 

 ous-black, immediate apex slightly paler; femora castaneous, tibiae and tarsi 

 fuscous; labrum, palpi and antennae piceous, the latter paler and fus- 

 cous toward tip; pubescence of the anterior portions sparse, of the elytra 

 moderately dense, long, rather coarse, of the abdomen dense, somewhat seri- 

 ceous, fulvous; integuments polished, not at all alutaceous. Head rather 

 small, distinctly longer than wide; base truncate, angles rather broadly
