266 THE CANADIAN ENTOMOLOGIST. 



eyes moderately small, but slightly prominent ; fove?e separated by less 

 than the distance of either from the eye ; surface coarsely, densely punc- 

 tate everywhere except in the moderate frontal depression, bounded by the 

 short parallel sulci : antennae one-half longer than the head ; prothorax 

 much narrower than the head, slightly wider than long, shining, minutely, 

 sparsely punctate, the discal fovea large and elongate ; elytra parallel, as 

 long as the head and prothorax, and slightly wider than the form.er, 

 decidedly longer than wide, the discal stria evident, extending slightly 

 behind the middle ; abdominal segments equal, not quite as wide as the 

 elytra, the basal medial impressions subobsolete. Length, 1.3-1.4 mm.; 

 width, 0.35 mm. New Mexico (Cloudcroft), Warren Knaus, 



The male has a large, deep, rounded impression involving the median 

 part of the sixth and anterior part of the seventh or large convex ventral 

 pygidium, the latter with a double impressed longitudinal line. 



Euplectus Duryi, n. sp. — Slender, less linear and depressed, shining, 

 subimpunctate, piceo-testaceous, the pubescence moderate ; head wider 

 than long, moderately large, the eyes small, the tempora converging 

 slightly to the truncate base ; foveae small, separated equally from each 

 other and either eye ; surface wholly impunctate along the middle from 

 base to apex, the lateral parts coarsely but not very closely punctate ; 

 antennae rather short ; prothorax wider than long, evidently narrower than 

 the head, prominently rounded laterally near the apex, the sides strongly 

 converging and nearly straight thence to the base, the discal fovea rather 

 small, only moderately elongate ; elytra somewhat shorter than the head 

 and prothorax, evidently though not greatly wider than the former, slightly 

 elongate, the discal stria evanescent slightly before the middle ; abdomen 

 as long as the elytra and very nearly as wide, the two basal segments each 

 with two rather long diverging basal carina3 medially. Length, 1.3 mm.j 

 width, 0.28 mm. Ohio (Cincinnati), Charles Dury. 



The male has«^ small median fovea at the apex of the sixth ventral, 

 the large convex ventral pygidium eccentrically divided by a fine 

 longitudinal carinule. 



Leptop/ecius, n. gen. 

 The minute and extremely slender linear species of this genus have 

 the head large and well developed, with two rather approximate fovese, 

 more anterior in position than the large pubescent and very widely
