Miscella7iies. 379 



Abdomen and tail wanting in our specimen, believed to be tuber- 

 cular throughout — (as a fragment presents that appearance.) 



Breadth of the head one inch and a quarter ; length three quarters 

 of an inch. 



(2.) Ceratocephala ceralepta. 



Communicated to the Western Academy of Natural Science at Cincinnati, April 

 14th, 1838, by John G. Anthony. 



Ceratocephala ceralepta. — Clypeo antice rotundato, subplano, V 

 granulato. 



Margine crenulata. 



Cornibus prorsum expansibus et gracilibus.* 



The buckler is semi-lunate, surface covered with fine granulations 

 resembling shagreen ; its margin is raised, presenting a rounded rim, 

 over which pass two antennae, distant from each other where they 

 pass over, about one fourth of an inch. These antenna extend 

 one third of an inch beyond the rim, and are 

 only one third of a line in diameter, forming a 

 character from which we derive our specific 

 name, " ceralepta" (slender horned) ; their ex- 

 tremities are broken off, and it would appear 

 that they have been several lines longer ; they 



diverge a little at their extremity, being about one line more distant 

 there than at the margin of the buckler ; they are inserted about one 

 line within the rim. Between the horns there is a triangular process 

 extending from the rim back as far as their insertion ; this has two 

 deep sulci on each side, separating it from the antennae. No abdomen 

 or tail has yet been found, which could be identified as belonging to 

 this species. 



Only two specimens are known to have been found, both by my- 

 self. They were discovered among the rubbish thrown down from a 

 quarry, half a mile from this place. Millions of fragments may be 

 found there of Calymenes, Isoteli, &c., and we may hope a more per- 

 fect specimen of our own species. 



"When first shown to some scientific friends, it was pronounced a 

 part of Ceraurus pleurexanthemus, and Dr. J. Green so judged it from 

 an imperfect cast shown him. Those who have since had an oppor- 

 tunity of comparing my specimen with a Ceraurus pleurexanthemus
