E. pallipennis Lee, (Nomophlceus), Class. Col. 1861, p. 86. — Cylindrical, 

 slightly depressed, piceous, front paler, elytra luteous, suture with a narrow 

 piceous margin dilated at apex. Head sparsely punctate. Antennae brownish. 

 Thorax as wide as long, slightly narrowed posteriorly, sides nearly straight, 

 margin slightly serrate near the hind angles, surface finely alutaceous and 

 with coarse, slightly elongate punctures sparsely placed and much finer afe 

 the sides, middle of disc impunctured and with a moderately deep crescentic 

 impression near the base. Elytra not wider than the thorax, surface finely 

 alutaceous and with strise of moderate punctures not deeply impressed, finer 

 at tip. Body beneath sparsely and rather finely punctate; first ventral seg- 

 ment with distinct coxal lines. Pygidium moderately punctate. Length .10 — 

 .12 inch; 2.5—3 mm. 



I have seen four specimens all collected in Pennsylvania. The 

 males have the additional terminal abdominal segment. 



E. impressicollis Woll., Ins. Mader. p. 150, pi. 3, Sg. 2. — Elongate, sub- 

 depressed, body beneath piceous, above pale castaneous, elytra with suture 

 and margin narrowly, tip more widely piceous. Head sparsely punctate at 

 sides and base. Antennae rufo-testaceous. Thorax longer than wide, sides 

 parallel, surface finely alutaceous, middle of disc with vague longitudinal 

 impression on each side of which are sparsely placed punctures. Elytra not 

 wider than thorax, subdepressed, sides parallel, surface with striae of moderate 

 punctures rather distantly placed. Body beneath very sparsely punctate. 

 Pygidium sparsely but more evidently punctate. Length .09 inch; 2.5 mm. 



The punctures of the elytra as well as those on the under surface 

 bear short hairs. 



This species is one of the discoveries of Mr. Wollaston, in the 

 Madeiras, and although not belonging at all to our fauna is intro- 

 duced in the present paper for comparison. 



E. longicollis n. sp. — Elongate, subdepressed, rufo-ferruginous. Head 

 moderately coarsely but not densely punctate. Thorax one halfjonger than 

 wide, sides parallel, apex rather suddenly narrowed and very slightly tubu- 

 late in front, disc moderately convex and regularly punctate over the entire 

 surface. Elytra not wider than the thorax, parallel, disc with rows of rather 

 closely placed punctures, moderately deeply impressed. Prosternum sparsely 

 punctured at the sides. Metasternum sparsely and more finely punctate. 

 Abdomen moderately densely punctate, first segment more sparsely and finely. 

 Pygidium moderately densely punctate. Length .14 inch; 3.5 mm. 



The male has the first ventral segment moderately deeply longi- 

 tudinally impressed, and in the impression on each side a row of fine 

 hairs. The first ventral of the female is simple. 



This species has a difi"erent appearance from the other two by its 

 elongate form, and the slight prolongation of the thorax anteriorly 

 in a tubulate manner. I cannot find any generic character for its 

 separation. 



Three specimens, California and Nevada.
