182 DESCRIPTIONS OF AND OBSERVATIONS ON 



being rectilinear, and in the crimped appearance of the base of the 

 elytra, &c. 



60. E. discoiileus, Weber.* Remarkable by the golden hairy head 

 and sides of the thorax. This is the pennatus, Fabr. ; but Weber's 

 name has the priority, and must therefore be adopted. 



61. E. lepturus. Blackish; spines acute; elytra with approximated 

 series of punctures. — Inhab. U. S. — Pennsylvania, Indiana, and North 

 Carolina. Harris. 



Body bJack-brown, punctured, rather slender: clypeus concave, 

 truncate at tip, and emarginate each side at the insertion of the an- 

 tennae : antennx rufous, serrate ; second joint not half the length of the 

 third: thorax with a dorsal, slightly indented line; lateral edge not 

 arcuated ; a little narrowed before, and contracted at the spines; spines 

 excurved, acute : 5c«/e/ rounded behind : elytra with approximate series 

 of deep punctures, with an appearance of striae, the series alternately 

 larger: pectus, tarsal grooves obvious. — Length two-fifths of an inch. 



Resembles discoiileus, Weber, but is always destitute of the golden 

 hair of the head and thorax. It is the lepturus of Melsheimer's Cata- 

 logue. 



62. E. impressicollis, S. (Ann. Lye. N. Y., I., p. 260.). Resem- 

 bles lepturus, S. ; but may be distinguished by its ferruginous colour. 



63. E. rectangularis, S. (Ann. Lye. N. Y., I., p. 263.), The pos- 

 terior angles of the thorax are rectangular, and the antennae remarkably 

 short. 



64. E. avitus. Blackish; rather long; scales yellow and black; 

 spines acute, hardly excurved. — Inhab. Indiana. 



Body black, with a slight tinge of piceous, punctured ; scales inter- 

 mixed, black and bright yellow; rather slender: clypeus hardly ele- 

 vated before ; anterior edge very obtusely arcuated, a little concave : 

 antennx serrate, rufous; second joint small, subglobular: thorax with 

 an obtusely indented line behind the middle; lateral edge very slightly 

 arcuated, and slightly excurved at the spines; spines very slightly ex- 

 curved, acute, not carinated: scutel concave, rounded behind: elytra 



* " Observationes Entomologicae." This work, which was presented to me by Professor 

 Wiedeman, was published in the same year with the Syst. Euleut. ; but, as Fabricius quotes 

 Weber's work, the priority of the latter is evident.
