more than twice their own width ; occipnt descending snbverti- 

 cally to the neck in profile ; antenniB missing. Prothorax small, 

 distinctly narrower than the head, only slightly wider than long, 

 narrowed and very feebly arcuate at apex, finely, densely punc- 

 tate, the basal impression broad, deep and nearly straight. Elytra 

 oblong, three-fifths longer than wide, rather more than twice as 

 wide as the prothorax, distinctl}^ impressed near the base and 

 within the humeri, the omoplates small and prominent ; punc- 

 tures small but deep and clearly defined on the polished surface, 

 moderatelj^ close-set. Legs missing. Length 1.4 mm.; width 0.6 

 mm. 



Ontario (Severn). The original description of Dr. Hamilton is 

 altogether insufficient, and I am somewhat doubtful of the refer- 

 ence, as the medium of publication omits signature marks. The 

 specimen before me lacks the head and all the legs, and is one of 

 the two original ty[)es recentl}^ sent to me by the author ; the 

 above description of the head is from pencil notes and diagrams 

 taken from the best preserved of the t3qoes. This species is some- 

 what closel}^ allied to piceus, but is evidently distinct. 



4. V. Tigilans n. sp. — Narrow, moderately convex, dark piceo-castan- 

 eous, the legs and antennae but slightly paler; head blacker; vestiture minute 

 and dense. Head transverse, rather convex, polished, minutely and somewhat 

 sparsely punctate, the punctures elongate and with their axes oblique to the 

 median line; eyes large, convex, separated by one-half more than their own 

 width; antennfe rather thick, densely pilose, scarcely two-fifths as long as the 

 body, gradually and feebly incrassate, the tenth joint about as long as wide. 

 Prothorax distinctly narrower than the head, only slightly wider than long, 

 parallel, narrowed and broadly arcuate at apex, minutely, densely punctate, 

 the basal impression deep, transverse, shallower in the middle but perfectly 

 continuous. Elytra three-fifths longer than wide, barely twice as wide as the 

 prothorax, parallel and broadly arcuate at the sides, becoming straight near the 

 base, broadly, obtusely rounded at apex; humeri rounded, moderately exposed 

 at base; disk broadly impressed near the base and thence narrowly and 

 obliquely within the humeri; omoplates rather small and moderately promi- 

 nent; punctures fine but strong, dense and almost equal from base to apex. 

 Abdomen finely but somewhat sparsely punctate, minutely pubescent. Length 

 1.3 mm.; width 0.55 mm. 



New York. Mr. H. H. Smith. 



This species is allied to the preceding, but difli"ers conspicu- 

 ously in its narrow and more convex form of body, denser punc- 

 tuation and vestiture, much larger e^^es, difterent sculpture and 

 convexity of the vertex and in several other characters.
