AMERICAN COLEOPTERA. 151 



I consider the typical form, in the almost total absence of erect hairs 

 and the more distinctly pedunculate legs, but agree so perfectly in 

 the serrulate sides of the prothorax, deeply impressed epistomal 

 suture and palpal formation that I am loath to consider them distinct. 

 In all females of the assumed typical form the last ventral segment 

 is bituberculate each side, but in variable degree. This character is 

 not clearly evident in the Vancouver female, nor is it present in the 

 varietal form mentioned above. 



21. E. geiitilis u. sp.— Strongly elongate, blackish brown, tarsi paler. Head 

 and thorax rather densely granulate and dull, elytra with sparser simple punc- 

 tures, which become suhasperate at base; pubescence very short, fine and incon- 

 spicuous. Eyes small, their vertical diameter scarcely half ( % ) or about one-third 

 ( 9 ) the width of the front. Terminal joint of palpi a little narrowed apically. 

 Antennae slender, ten jointed, joints two and three nearly equal in length, fourth 

 and sixth subeqiial and shorter, fifth and seventh subequal and still shorter, rather 

 wider than long; eighth a little longer than the four preceding in the female, 

 more parallel and longer than the five preceding in the male. Prothorax not 

 quite as wide as the elytra, sides moderately strongly rounded and a little re- 

 flexed, front angles more rounded than usual, hind angles scarcely defined. Pro- 

 sternum moderate in length before the coxae; metasternum not clearly punctate. 

 Legs slender. Length 3 mm. 



Easton, Washington (Koebele); North Bend, British Columbia 

 (Schwarz). 



This species agrees with the next only, in the 10-jointed antennas, 

 but it is quite normal in prothoracic structure, while that is decidedly 

 aberrant. 



22. E. trapezoideus n. sp. — Very elongate, pale yellowish brown, head 

 and under surface piceous brown ; pubescence short, fine and sparse. Head across 

 the eyes much wider than the prothorax, the eyes ( % ) very large and convex, 

 their vertical diameter about three- fourths the frontal width; epistomal suture 

 impressed; surface alutaceous, rather sparsely subgranulately punctate. Last 

 palpal joint widest behind the middle and narrowing apically. Antennae 10- 

 jointed, joints two, three and five about equal in length, four just visibly longer; 

 six slightly shorter; seventh shortest but evidently longer than wide, eighth, 

 ninth and tenth very narrow, linear, subequal, and each about as long as joints 

 three to seven united. Prothorax evidently narrower than the elytra, trapezoi- 

 dal in form, the sides not distinctly margined, straight and a little convergent 

 anteriorly, hind angles sharply defined and nearly right, front angles a little 

 obtuse, surface alutaceous and slightly scabious but not distinctly granulate, a 

 transverse median impression. Elytra finely simply punctate. Prosternum 

 rather long before the coxae. Legs very slender, first tarsal joint subequal to the 

 next three. Sixth ventral strongly rounded and not at all emarginate at apex. 

 Length 3-4 mm.
