the pronotum; sides moderately strongly divergent and feebly arcuate toward 

 the a-pex; together broadly and feebly sinuate behind; disk about as long as 

 wide; as long as the pronotum, depressed, feeblj'^ impressed throughout near 

 the suture which is feebly elevated, rather coarsely, moderately densely and 

 sub-rugulosely punctate. Abdomen at base very nearly as wide as the elytra; 

 sides just visibly divergent posteriorly and straight; surface very minutely, 

 densely, irregularly, feebly and sub-asperately punctate. Legs long and slen- 

 der; tarsi rather short, fir.^t joint of the posterior much shorter than the next 

 two together, scarcely as long as the fifth, one-third longer than the second; 

 first four joints uniformly decreasing in length. Length 4.6 mm.

The anterior tarsi are feebly dilated toward base. This 

 species may be readily recognized amongst the large species 

 with short elytra, by its much paler color, slightly coarser 

 and sparser cephalic punctuation, and by the distinctly sin- 

 uate sides of the prothorax. 



11 — L. COnverffens n. sp. — Form moderatelj^ robust, black throughout; legs 

 dark piceous-brown, tarsi i)aler, testaceous; antennae fuscous, paler toward the 

 apex; pubescence very fine, rather long, very sparse anteriorly, more dense on 

 the elytra, still denser and more sericeous on the abdomen, l^eac? large, broadly 

 sinuate at base, angles rather broadly rounded; sides long, feebly convergent 

 anteriorly, distinctly and evenly arcuate; eyes very small; epistoma very 

 slightly produced, broad, squarely truncate at apex; surface finely and densely 

 punctate, very feebly alutaceous; j)uuctures rather feebly impressed, distant 

 by scarcely more than their own widths above; median line narrow; antennse 

 one third longer than the head, rather slender, second joint distinctly shorter 

 than the third, very slightly longer than the fourth, tenth slightly wider than 

 long. Prothorax widest at the apex where it is slightly narrower than the 

 head and distinctly wider than long; sides moderately strongly convergent 

 posteriorly, very feebly end evenly arcuate; base broadly and rather feebly 

 arcuate; apex rather more strongly arcuate, broadly siuiiate in the middle 

 two-fifths; anterior angles rather broadly rounded, basal very broadly so; disk 

 finelj'', very feebly and sparsely punctate, with an entire and rather wide me- 

 dian impunctate area, and, especially toward base, a very tine and feebly im- 

 pressed median stria. Elytra at base distinctly narrower than the pronotum; 

 sides rather strongly divergent and nearly straight; together broadly, feebly 

 and sub-angularly sinuate at the apex; disk about as wide as long, slightly 

 longer than the pronotum, depressed, feebly impressed along the slightly ele- 

 vated suture, except at the apex, moderately coarsely, densely and evenly 

 punctate; punctures feebly sub-rugulose. Abdomen at base distinctly nar- 

 rower than the elytra; sides slightly divergent posteriorly; surface verj'' finely, 

 •densely, irregularly and sub-asperately punctate. Legs rather short and slea-
