COLEOPTERA. 135 



brown from the pubescence, bases of the segments reddish from tlie 

 transmitted light ; under surface of abdomen of tlie same color as the 

 upper, bristling with long dense coarse erect setae toward tip. In 

 the second specimen the elytral punctures are arranged in tolerably- 

 well-defined rovvs nearly throughout the elytra. 



Following the characters of Dr. LeConte's table of this genus as 

 carefully as possible, it appears to come immediately after his 

 ambiyiium. 



L.. inops n. sp. — Form very slender, sub-depressed; color of body dark 

 reddish-testaceous, abdomen slightly darker, legs slightly paler and more 

 flavate, antennae slightly more flavate toward tip ; pubescence long, very 

 sparse and fine, recumbent, not conspicuous, scarcely thicker on the abdo- 

 men. Head large, distinctly longer than wide, widest at one-fourth the 

 length from the base ; eyes very small, not at all prominent, at more than 

 their own length from the angles of the epistoma, and at three times their 

 lengtli from the basal angles ; sides behind them just visibly divergent 

 posteriorly and rather feebly arcuate ; basal angles broadly rounded ; base 

 transversely truncate ; interocular surface broadly and evenly convex, shin- 

 ing, rather finely evenly and somewhat sparsely punctate, with a narrow line 

 almost impunctate along the middle ; supra-antennal angulations rounded 

 exteriorly, rather distinctly swollen, each with a small setigerous puncture ; 

 anterior edge of the epistoma broadly truncate and distinctly sinuate in the 

 middle, three-fifths as long as the greatest capital width ; antennae three- 

 fourths as long as the head and prothorax together, very robust throughout, 

 not appreciably thickened toward tip, first joint nearly as long as the next 

 two together, strongly narrowed toward base, scarcely twice as long as wide, 

 second slightly narrower, slightly elongated, very little shorter than the third 

 and longer than the fourth, joints four to ten about as long as wide, eleventh 

 small, acutely conoidal ; second joint of maxillary palpi slightly bent ; neck 

 short and broad. Prothorax slightly narrower than the head, slightly more 

 than one-third longer than wide; sides nearly parallel and almost straight 

 in the middle ; anterior and posterior angles broadly rounded toward the 

 sides, more acutely rounded next the anterior and posterior margins, the 

 former broadly arcuate, the latter very slightly shorter, transverse and feebly 

 sinuate in the middle; disk rather depressed, polished, rather broadly im- 

 punctate along the middle ; punctures rather small, aggregated densely in 

 a broad irregular line at the borders of the impunctured area, then more 

 sparse, and again more dense near the edges where they appear to tend to 

 an irregular linear formation. Elytra at base scarcely as wide as the pro- 

 notum ; sides rather strongly divergent posteriorly and extremely feebly 

 arcuate, nearly straight ; together broadly triangularly and rather strongly 

 emarginate behind ; exterior apical angles broadly rounded behind ; disk 

 very feebly convex, narrowly and rather strongly impressed along the 

 suture, distinctly shorter than the pronotum, and slightly longer than the 

 apical width, highly polished, and extremely feebly irregularly and some- 

 what sparsely punctate. Abdomen at base slightly narrower than the con-
