Genus XCV. b.-ENICOCERUS mihi. 



Palpi short; maxillary rather stout; the basal joint more slender than the fol- 

 lowing, which is somewhat clavate, tumid, with the apex obtuse. An- 

 tenna with the basal joint elongate, slightly bent, incrassated at the apex ; 

 second joint short, somewhat quadrate: third large, cup-shaped; fourth 

 minute, subglobose, two folio wing gradually larger, the remainder forming 

 an elongate five-jointed club, the first joint of which is large, subglobose, the 

 two following smaller and of equal size ; the next large, transverse, the ter- 



> minal one small, semiovate, obtuse: head triangular: eyes slightly prominent: 

 thorax subcordate : elytra broad, depressed : legs moderate ; tarsi with large 

 claws. 



The singular structure of the antennse of this remarkable genus, with its broad, 

 somewhat depressed body, large claws and abbreviated palpi well distinguish 

 it from others of the Helophorida, to which family it appears to belong.

The accompanying figure of this singular insect will sufficiently illustrate its 

 peculiar characters : the insect was taken at " Hebden-bridge, Yorkshire, in 

 October 1828." — Mr. Gibson; to whom I am indebted for my specimens.
