AMERICAN COLEOPTERA. 135 



A widely distributed species, having been taken in Western 

 Nevada (Morrison); Brightens, Utah; Marquette and White Fish 

 Point, Michigan (Schwarz) ; and Anticosti Island (Dr. J. Schmitt). 



MICROZOGUS new genus. 



The above name is proposed for a minute species evidently allied 

 to Ozognathus, but differing in its more compact form, glabrous sur- 

 face, 10-jointed antennae, and by the mesosternum being vertical 

 between the coxse. The presternum is excessively short before the 

 coxae. The first ventral suture is nearly as well defined as the 

 others. 



1. M. insolens n. sp. — Oblong-elliptical, varying in color from pale brown 

 to piceous, surface shining, glabrous, very sparsely minutely punctate. Prothorax 

 as wide as the elytra, strongly transverse, the sides explanate, all the angles 

 rounded. The antenual club is longer than in Ozognathus, being distinctly longer 

 than all the preceding joints united, the first joint of the club quite as long as 

 the terminal joint. The first four joints are proportioned nearly as in Ozognathus, 

 the next three are very short and difficult to count. The presternum is scarcely 

 punctured at sides; the metasterunm is distinctly but not closely punctate. The 

 tarsi are short, the first joint scarcely longer than wide, at least on the front feet. 

 Length 1-1.3 mm. 



Florida (Key West and Biscayne). 



OZOGNATHUS LeCoute. 



The members of this genus are small, oblong, subcylindrical, con- 

 fusedly punctate and sparsely or moderately pubescent. Mentum 

 subtrapezoidal ; basal joint of maxillary palpi small, second and 

 third joints a little elongate and widened apically, terminal joint 

 larger, scarcely twice as long as wide, feebly dilated near the mid- 

 dle, the apex truncate ; labial palpi similar, the terminal joint widest 

 near the apex. Antennas less than half the length of the body, the 

 intermediate joints small and almost cylindrical, the third, fifth and 

 seventh visibly longer, ninth to eleventh enlarged, forming a club, 

 which is about equal in length to all preceding; the ninth triangu- 

 lar, twice as wide and about as long as the three preceding, the 

 tenth similar but a little shorter, the eleventh visibly longer, elon- 

 gate-oval. Eyes small, prominent. Prothorax evenly convex, with 

 distinct angles. Elytra parallel and scarcely or slightly wider than 

 the thorax. Anterior coxae oval, not very prominent, narrowly sep- 

 arated, the prosternal process scarcely wider behind ; presternum
