NORTH AMERICAN COLEOPTERA. 225 



testaceous; pubescence fine and dense throughout, longer on the head, less 

 conspicuous on the pronotum. Head much longer than wide; sides parallel 

 and distinctly arcuate; base transversely truncate; augles not prominent 

 though rather narrowly rounded; front transversely, rather strongly convex, 

 extremely minutely, feebly, evenly and not densely punctate; eyes at much 

 more than twice their length from the base; antennae short, scarcely longer 

 than tho head, rather robust, second jjint very slightly longer than wide, 

 slightly longer and much more robust than the third, tenth rather strongly 

 transverse. Proihorax very slightly narrower than the head, widest at one- 

 third its length from the apex; anterior angles very broadly rounded; sides 

 almost parallel and distinctly arcuate; base transversely truncate, angles 

 rather broadly rounded; disk nearly one-third longer than wide, moderately 

 and evenly, cylindrically convex, very minutely, evenly and rather densely 

 punctate; punctures appreciably closer than those of the head; throughout 

 the basal three-fifths there is a fin9, well-marked, median stria. Elytra at 

 base distinctly wider than the prothorax aud fully as wide as the he id; sides 

 parallel and very feebly arcua'e; together distinctly longer than wide and just 

 visibly longer than the pronotum; surface rather feebly convex, rather nar- 

 rowly and feebly impressed along the suture toward base, very minutely, 

 evenly and densely punctate; punctures slightly coarser aud just appreciably 

 more dense than those of the pronotum. Abdomen very slightly narrowed to- 

 ward base, excessively minutely, feebly and rather densely punctate. Femora 

 and tibiae as in bicolor. Length 1.9 mm. 



Texas; (Austin 1). 



This species is aberrant not only in the more broadly 

 rounded apical angles of the prothorax, the elongate head 

 and shorter antennae, but in the smaller eyes, more com- 

 pressed and truncate third maxillary palpal joint, and espe- 

 cially in the position of the spongiose setigerous fovea, 

 which is not at the middle of the upper margin of the eye 

 as in the other species, but behind the eye one-half the 

 length of the latter, and in a line with its upper margin. 

 The neck also is relatively much less slender than in the 

 other species. With exception of Leptogenius brevicornis it 

 is the smallest Psederide described from our territories. 

 Unfortunately there is before me but a single representa- 

 tive, a female, so that the sexual characters of the male can- 

 not be given; the form is very distinct, however, and will 

 be easily recognizable.
