Coleopterological Notices, IV. 695 



elongate subbilobed punctures ; intervals flat, but slightly wider than the 

 serial punctures, each with a single uneven series of minute, feeble punc- 

 tures. Under surface throughout rather finely but deeply and somewhat 

 densely punctate. Length 2.8 mm. ; width 0.9 mm. 



Minnesota. 



Easily distinguishable from any species of Rbyncolus by its de- 

 pressed form, narrow beak and prothorax, and pubescent surface. 



APOTREPUS n. gen. 



A single species again constitutes a genus which is without any- 

 close ally in our fauna. 



Body stout, subcylindrical, moderately convex, the elytra wider than the 

 prothorax, the scutellum distinct ; upper surface setose. Head short, broad, 

 cono-globose, not conspicuously separated from the beak. Beak rather short, 

 robust, parallel toward base but dilated toward apex. Eyes situated at the 

 sides, partially on the beak, distant from the prothorax, feebly convex and 

 rather prominent, somewhat coarsely faceted. Antennae inserted at the 

 middle, the scrobes deep, linear, obliquely descending to the lower limit of 

 the eyes; scape robust; funicle long, 7-jointed, the two basal joints equal, 

 each longer than wide and longer than three to seven, which are subequal 

 in length, gradually thicker, obconical, submoniliform, the articulations 

 strongly marked ; club oval, densely but coarsely pubescent, abrupt, fully 

 as long as the preceding four joints, not annulate. Anterior coxae small, re- 

 mote, separated by fully their own width ; intermediate still more widely 

 separated. Metasternum long. Legs rather long but somewhat stout, the 

 tibiae parallel, with a small internal spur and well-developed external uncus 

 at apex ; tarsi rather long, the basal joint nearly as long as the next two, 

 third feebly dilated, fourth but slightly longer than the preceding two com- 

 bined. 



Apotrepus is related to Caulophilus latinasus perhaps more 

 closely than to any other North American species, resembling it 

 in general form of the body, but differing greatly in its shorter 

 beak dilated near the apex, in its smaller eyes, longer second funic- 

 ular joint, and in the sparse bristling and setiform vestiture. 



A. densicollis n. sp. — Black, the antennae and legs feebly rufescent, 

 rather shining, the setae short, stiff, erect, forming an uneven single line on 

 each elytral interval. Head very short, finely, sparsely punctate, the beak 

 nearly straight, densely, subrugosely punctate, more than twice as long as 

 the head and separated therefrom only by a very broad transverse impres- 

 sion, from the anterior margin of the eyes to the apex one-half as long as the 

 prothorax, not twice as long as wide viewed anteriorly. Prothorax about as 

 long as wide, broadly, strongly constricted behind the apex, the sides feebly
