S. i^ubriiriis Eand. — Color pale ferruginous, feebly shining, very incon- 

 spicuously pubescent; antennte passing slightly the hind angles of the thorax; 

 head coarsely and densely punctured ; clypeus not wider at base than half the 

 distance to the eye ; thorax as wide as long, slightly narrowed in front, sides 

 straight, arcuate at the front angles, hind angles acute, not carinate, disc moder- 

 ately convex, a slight median deijression posteriorly, surface coai-sely and densely 

 punctate ; elytra finely striate, the intervals flat, sub-biseriately rugosely punc- 

 tate ; body beneath moderately densely punctate. Length .32 inch ; 8 mm. 



This is rather an inconspicuous species, resembling, at first sight, 

 some of the paler varieties of Dolopim lateraJis. It seems to be ex- 

 tremely rare. I have seen but two specimens. 



Occurs in Canada and New York. 



EPIPHAXIS Esch. 



Form rather elongate, parallel at middle, narrowed at each extremity ; antennae 

 slender, not serrate, the last four joints abruptly longer, varying in length in the 

 sexes, joints four to seven small, not hmger than wide ; clypeus arcuate in front, 

 as wide at base as the distance to the eyes ; eyes i-ound, feebly prominent, limited 

 in front by a slight groove ; prothorax wider than long, nai-rower in front ; scu- 

 tellum truncate at tip ; prosternal sutures straight, well defined in their whole 

 extent, the proijleurte vaguely grooved near the side margin, the marginal ridge 

 acute and entire ; metathoracic episterna parallel, the epimera invisible ; hind 

 coxal plates very broadly dilated internally, very narrow externally ; legs mod- 

 erate, tarsi slender, the fourth joint obliquely truncate, but not lobed beneath; 

 the first joint of the hind tarsi as long as the next three, claws broader at base. 



From the description of the antennae Bonvouloir seems to have 

 known only the female. 



There is but one species known, and which seems very widely 

 distributed. 



E. eoriiiitns Esch. — Form elongate, parallel at middle, attenuate at either 

 extremity, piceous, feebly shining, sparsely clothed with brownish pubescence ; 

 antennfe ferruginous, a little longer than half the body % or shorter 9 ; head 

 coarsely and densely punctured, carinate at middle, the carina more elevated in 

 front ; prothorax wider than long, gradually arcuately narrowed in front, hind 

 angles not carinate, disc convex, with a feeble median impression posteriorly, 

 surface moderately, coarsely, but not densely punctured ; elytra .striate, intervals 

 slightly convex, densely but not rugosely punctate ; body beneath more shining 

 than above, rather finely, densely punctate, the propleural triangle comparatively 

 smooth ; legs brownish. Length .14 - .24 inch ; 3.5-6 mm. 



Male. — Antenna^ a little longer than half the body, second joint longer than 

 the third, third nearly square, four to seven subequal, a little shorter than the 

 third and broader than hmg, joint eight a little wider than the seventh and 

 nearly as long as the preceding four, joints nine, ten and eleven .successively, a 

 little longer. 



Female. — Antennfe a little shorter than half the body, joints one to seven as in 

 the male, joints eight, nine and ten equal, each equal to joints six to seven to- 

 gether, joint eleven .slightly longer.
