thorax rather convex, dorsal indeiitatinn none, oxeoptinir some- 

 times a very slight one at base; latoral edge rectilinear IVum be- 

 fore the middle to the tip of the spines ; spines not excurvcd, 

 prominent, subacute, carinate; the carina nearly parallel to the 

 exterior edge : indentation between the thorax and abdomen 

 deep ; scutel somewhat indented : elytra with punctured stricB, 

 and with minutely and irregularly punctured interstitial lines; 

 beneath rufuus ; second and third joints of the tarsi each extend- 

 ing beneath into a prominent, flattened, membranaceous lobe, 

 that of the third much more obvious, rounded at tip, and ex- 

 tending much beyond the tip of the penultimate joint, which is 

 very small. 



Length from scven-twentieth.s, to more than eleven-twentieths 

 of an inch. 



This varies considerably in size, and the prominent obtuse cly- 

 peus, together with the elongated, membranaceous lobe of the 

 antepenultimate [177] tarsal joint distinguish it from other spe- 

 cies. Kesembles vuru//>ifii>!.

43. E. CUCULLATUS nob. (Ann. Lye. N. Y.) — May be distin- 

 guished from soleatus by the clypeus being obviously indented 

 above, and more obtuse, almost emarginatc on the anterior edge ; 

 the antenna) are more slender, and the last joint not, or hardly 

 longer than the .preceding one : thorax more slender, and the 

 spines more obtuse, shorter, and rounded at tip : the larger lobe 

 of the tarsi is not so prominent. The thoracic spines resemble 

 those of hsemorrhoidalis Fabr., but are more excurvcd.

44. E. DILECTUS nob. (Ibid.) — The penultimate tarsal joint of 

 this species is produced beneath into a membranaceous lobe.

45. E. vespertinus Fabr. — The penultimate tar.>*al joint is 

 minute, but is extended beneath into a dilated membraiiaceou.-i 

 lobe, half the length of the last joint. This species varies con- 

 siderably ; the elytra have generally a connecting black band be- 

 yond the middle ; they are rarely nearly all black, with one or
