170 J. L. LECONTE, M, D. 



One pair, collected by Mr. Jos. Willcox in Yosemite Valley, Cal. 

 The hind tarsi are marked on the outer side of the first joint with two 

 very fine and almost indistinct striae. This species bears a deceptive 

 resemblance to J'terostichiis tarsalis, and hcmilanens, (which is not 

 crcnicollis Lee, as has been stated in consequence of some confusion 

 of specimens), but is easily recognized by the impressed last ventral 

 segment of both sexes, and the serrate tibiae of the % . 



Copropllilus Striatnlu$>i Er. Staphy. 816; Staphylinus atrial. Fabr.,etc. 

 A specimen of this rare European species was found by Mr. Pettit 

 in Canada, and kindly given to me. 



Zalobius serricollis. — Depressed, piceous, covered with a dirt colored 

 crust, densely punctured. Head with an acute elevated line each side from 

 the front to the occiput, and two short elevated lines behind; base truncate, 

 hind angles rounded. Prothorax wider than the head, one-half wider than 

 long, ovate, narrowed behind, sides broadly flattened, distinctly and obtusely 

 serrate; disc with four fine elevated lines. Elytra with numerous striae and 

 elevated lines, of which the humeral and submarginal are most conspicuous ; 

 the former becomes indistinct behind, and the latter in front. Abdomen 

 sparsely finely pubescent. Length 3.4 mm.; .1.3 inch. 



Owen's Valley, California; Dr. Horn. Very different in specific 

 characters from Z. spinicollis, though apparently belonging to the 

 same genus. 



Colastus ogavensis and yuccse, Crotch, Trans. Am. Ent. Soc, both 

 belong to Carpophllus ; the anal segment of the % is quite distinct; 

 the first is allied to discouleus, the second to melanopterus. 



Dacne picea. — Oval elongate, convex, shining piceous, glabrous; head 

 and prothorax finely not densely punctured, sides of the latter nearly straight, 

 except towards the tip, where they are feebly rounded. Elytra more finely 

 punctured, punctures not arranged in rows; humeri rufo-piceous. Beneath 

 I)unctulate finely pubescent, antennae and legs ferruginous. Length .3 mm. ; 

 .12 inch. 



One specimen, California. Quite distinct from our other two species 

 by the finer punctuation, which on the elytra is not arranged in rows, 

 by the absence of elytral spots, and by the sides of the prothorax 

 nearly straight, converging in front. The elytra are also compara- 

 tively longer. , 



Mr. Crotch was quite correct in restoring the name Dacne Latr., 

 (179G), to this genus and suppressing Engis Pai/k., (1798J. 



IIYPODACXE, n. g. 



1 have established this new genus upon a small insect resembling in 

 form, mouth, sternum, coxae and legs Daoie, but differing by the tarsi 

 not hairy beneath, with the joints one to four shorter, closely united
