I leave this subject, therefore, with the opinion that the specimen 

 labeled oHvaceus in the cabinet of LeConte, is not the orig-inal 

 type, and further that the specimens from Detroit may fairly be 

 assumed to represent that species ; the latter seems, at least, a 

 better course to pursue than to frive this undoubtedly valid species 

 a new name, based upon an uncertainty of identification. 



L.. perforatlis n. sp. — Form oblong-oval, strongly rounded behind, 

 rather less than twice as long as wide ; sides nearly straight in the middle ; 

 black : pubescence very coarse, somewhat dense, feebly mottled cinereous and 

 fulvous ; integuments polished throughout. Head very coarsely, deeply and 

 densely punctate, the punctures on the flat vertical front tending to coalesce in 

 a subtransverse, slightly posterior direction from the median line. Prothorax 

 more than twice as wide as long ; sides feebly, evenly but very distinctly 

 arcuate ; apex more than two-thirds as wide as the base, the basal lobe mode- 

 rate in width, prominent ; median gi'oove short, broadly, feebly impressed and 

 not very distinct ; surface rather finely, sparsely punctate, the punctures much 

 less than one-half as wide as those of the elytra, and separated by twice their 

 own widths, coarser and denser toward the sides. Scutellum moderate, slightly 

 convex, just visibly longer than wide ; sides very strongly arcuate ; base feebly 

 so ; basal angles rounded ; surface rather sparsely and finely punctate. Elytra 

 bi;t slightly more than three times as long as the prothorax and scarcely per- 

 ceptibly wider, very coarsely, deeply and densely punctate, the punctures 

 separated by one-half their own widths. Prosternum polished, extremely 

 finely and sparsely punctate throughout ; median groove narrowly but deeply 

 impressed, continuous almost throughout the entire length ; episterna ap- 

 proaching the apex within two-thirds their own length, abruptly limited 

 within except near the anterior angle, impuuctate ; hypomera very strongly 

 impressed near the inner angle, polished, rather coarsely punctate, the punc- 

 tures separated by about twice their own diameters ; inner bead strongly 

 developed. Abdomen in the middle not very coarsely punctate, the punctures 

 separated by twice their own widths, coarser and slightly closer near the sides, 

 polygonally crowded on the last segment which is not impressed and with the 

 pubescence dense in the middle. Length 1.7 mm. 



California (Santa Clara Co.). 



This species is distinguished by its remarkably sparse and fine 

 punctuation of the prothorax, above and beneath, for this section 

 of the genus, and contrasting remarkably with the very coarse 

 dense punctuation of the elytra. The abdomen is much more 

 sparsely punctate than in any of the other species of this subgenus. 



\j. teiiuicorilis n. sp. — Ovoidal, pointed behind, about three-fourths 

 longer than wide, widest near the middle, black, moderately shining ; pubes-
