dilated, &c. A variety from Dr. Harris has the elytral fascia 

 extending to the tip, and in size is a little longer. 

 [Belongs to Cryptohypnus. — Leg.] 



31. E. CURIATUS.— Blackish ; elytra yellowish, with a black 

 band ; thorax with a fissure each side at base. 



Inhabits United States. 



Body blackish-livid, with minute punctures : clypeus obtusely 

 rounded, edge reflected : antennas rufous, rather robust, a little 

 serrate ; second joint two-thirds the length of the third ; ultimate 

 joint hardly longer than the preceding one : thorax with a fissure 

 in the posterior edge near the spines ; spines not carinate, but the 

 lateral edge is somewhat reflected : scutel oblong, concave : elytra 

 with well impressed, punctured striae ; yellowish-white, with a 

 dusky band on the middle expanding a little on the margin and

I obtained three specimens in June. 



[A species of Cardiophorus which was afterwards cited by 

 Erichson as Elater areolatm Say, to which it bears no resem- 

 blance. It is the only species from the Atlantic slope of the 

 United States known to me, having the ungues toothed: Say has 

 given an incorrect measurement ) it should read, length three- 

 twentieths of an inch. — Lec] 



32. E. SANGUiNiPENNis nob. Jour. Acad. Nat. Sci. — Closely 

 resembles jjraews^ws Fabr., which however, has the colors much 

 more vivid ; the punctures rather larger and more dense, particu- 

 larly those of the interstitial lines of the elytra ; the thoracic 

 spines longer ; and the second and third joints of the antennae of 

 our species are more cylindrical. [174] 



33. E. INFLATUS nob. Ann. Lye. Nat. Hist.— Resembles \olo- 

 sericem Fabr., but is still more robust, the thoracic spines are 

 longer, and the thoracic punctures more obvious. 



Inhabits also Massachusetts. Harris. 



34. E. FENESTRATUS nob. (Ibid.)— As respects the clytral 

 spot, it may be compared to the higutfatusFahT., but is not much 

 longer than the head and thorax of that species. 



[No such species is described by Say. — Lec]
