tudinally indented : clypeus obtusely rounded before, prominent : 

 antennae pale rufous, third joint a little longer than the second, 

 terminal joint not obviously contracted abruptly towards the tip: 

 thorax rather narrowed anteriorly, with an obsolete, dull, rufous 

 margin and dorsal line; [180] posterior angles very slightly ex- 

 curved, rather long, acute, with the carinated line very near to 

 the edge : scutel dull rufous : elytra with the striae impressed, 

 not confluent, and in which the punctures are not very obvious ; 

 interstitial lines depressed ; an obsolete, rufous, humeral spot, 

 and another on the middle of the exterior submargin : beneath 

 pale rufous : feet paler ; penultimate joint of the tarsi with a 

 membranaceous lobe. 



Length three-tenths of an inch. 



The body is more elongated than either dilcctus S., or Usectus S. 

 I a^ indebted to Dr. Harris for an opportunity to examine a spe- 

 cimen. 



[This is a variety of Monocrepidius vespertinus. — Lec] 



55. E. decoloratus Harris MSS. — Black ; elytra, antennae 

 and feet rufous. 



Inhabits New Hampshire and Pennsylvania. 



Body blackish, with pale hairs and minute punctures : clypeus 

 with larger punctures than the thorax ; two obsoletely impressed 

 diverging lines ; anterior edge subangulated, and the angles so 

 depressed as to appear confluent with the anterior part of the 

 head : antennae rufous, a little hairy; second joint two-thirds the 

 length of the third ; last joint longer than the first, not abruptly 

 contracted towards the tip : thorax convex blackish ; base with 

 a fissure each side ; posterior angles pointing backward, rather 

 obtuse and somewhat broad, with the carinated line rather short, 

 and not much elevated ; elytra dull rufous ; impressed, slightly 

 punctured strias, more deeply indented at base, and the third and 

 fourth confluent before the tip : feet pale rufous; fourth joint of 

 the tarsi not so distinctly lobed as the preceding joints. 



Length half an inch. 



Bare in Pennsylvania. Approaches the description of E. semi- 

 ru/us Germar, which, however, I believe to be smaller.
