176 DESCRIPTIONS OF AND OBSERVATIONS ON 



E. nemnonius, Herbst, Melsh. Catal. p. 42 — Tnhab. middle states. 

 Terminal joint of the antennae abruptly smaller at tip, and the tho- 

 rax is longitudinally indented behind the middle. 



40. E. baridius. Resembles the preceding, but is much larger, 

 more robust, the thorax more rounded each side, the second and third 

 striae of the elytra abbreviated and confluent at tip. — Length over nine- 

 tenths of an inch. 



Of this I have seen but one specimen, which was sent me for exa- 

 mination by Dr Harris. It was taken in North Carolina. 



41. Hemipodus, Nob. (Ann. Lye. N. Y.). Black-brown : antennse 

 with obconic-compressed joints, not obviously serrate; second joint 

 more than half the lengih of the third ; thoracic spines rather short 

 and obtuse ; the carina parallel with the outer edge: tarsi, first, second 

 and third joints extended beneath into pulvilli : thorax with a slight 

 fissure on the basal margin, near the posterior angles. 



42. 'E. soleatiis. Chestnut; clypeus prominent, rounded; second 

 and third tarsal joints extended beneath into a prominent lobe. — Inhab. 

 Indiana. 



Body dark chestnut brown, punctured ; with very numerous, short 

 hairs, not prostrate: clypeus prominent before, and obtusely rounded: 

 antennx a little serrate, rufous; second joint not longer than broad, not 

 more than half the length of the third : thorax rather convex, dorsal 

 indentation none, excepting sometimes a very slight one at base; late- 

 ral edge rectilinear from before the middle to the tip of the spines ; 

 spines not excurved, prominent, subacute, carinate ; the carina nearly 

 parallel to the exterior edge : indentation between the thorax and ab- 

 domen deep; scw/e/ somewhat indented: elytra with punctured striae, 

 and with minutely and irregularly punctured interstitial lines : beneath 

 rufous; second and third joints of the tarsi each extending beneath into 

 a prominent, flattened, membranaceous lobe, that of the third much 

 more obvious, rounded at lip, and extending much beyond the tip of 

 the penultimate joint, which is very small. — Length from seven-twen- 

 tieths, to more than eleven-twentieths of an inch. 



This varies considerably in size, and the prominent obtuse clypeus, 

 together with the elongated, membranaceous lobe of the antepenulti-
