founded is tiirgidicollis, and from that it can be at once separated 

 by its elongate antenna? and much more convex head, besides 

 elytral coloration. It is represented b}- a single female specimen. 



15. L,. tlirgidicollis n. sp. — Narrow, the elytra rather flat, polished, 

 pale testaceous, the elytra throughout, abdomen except at base, and antennae 

 toward apex, more or less dark piceous or blackish. Head rather longer than 

 wide, finely, sparsely punctate, the front flattened or even slightly concave 

 toward the median line and more densely reticulate ; base transversely arcuate, 

 the tempora subparallel and nearly as long as the eyes, which are moderately 

 large, prominent and distinctly setose; antennae very stout, feebly incrassate, 

 about as long as the head and prothorax, the tenth joint not at all longer than 

 wide. Prothorax large, very convex, finely, evenly and rather sparsely punc- 

 tate, only slightly narrower than the head, though much longer than wide, 

 the anterior lobe large, globular, not transverse, the basal lobe rather short, 

 dilated to the base ; constriction not extending obliquely upon the disk ; pubes- 

 cence scarcely distinct. Elytra three-fourths longer than wide, barely twice as 

 wide as the prothorax, parallel and nearly straight at the sides, the apex 

 rather abruptly, broadly subtruncate; disk even, the omoplates rather small 

 and moderately developed ; punctures fine and moderately sparse, becoming 

 subobsolete toward apex; vestiture only slightly more distinct toward base. 

 Abdomen finely punctulate, not ^'ery remotely pubescent, the legs slender. 

 Length 2.4 mm.; width 0.7 mm.

The parallel, even and slightly flattened elytra, large prothorax, 

 depressed front and elongate parallel tempora, will enable the 

 student to identify' this singular species, and the latter character 

 will also distinguish it from bipartitus, in addition to the charac- 

 ters given under that heading. It is represented b}- a single 

 female example. 



IG. L.. subtilis n. sp. — Narrow, shining, dark piceous-brown through- 

 out, the head and prothorax a little more rufous; legs concolorous; antenna; 

 black, pale fla^■o-testaceous toward base. Head orbicular, scarcely wider than 

 long, convex, finely, sparsely punctate; eyes moderately large, convex, the 

 tempora convergent and rounded Ijehind them for a considerable distance, the 

 base transversely arcuate, the angles very obtuse, feebly traceable; antennae 

 al)OUt one-half as long as the body, (juite distinctly and very gradually in- 

 crassate, the tenth joint slightly longer than wide. Prothorax moderate in 

 size, miich narrower than the head and slightly elongate, convex, finely 

 .sparsely punctate, the anterior lobe distinctly wider than long, oval, widest 

 near the middle, the i)osterior fully one-third of the total length, of moderate 

 width, gradually and distinctly expanded to the basal margin. Elytra three- 

 fourths longer than wide, fully twice as wide as the prothorax, the sides par- 

 allel, feebly arcuate behind, the apex moderately broadly truncate; disk
