PTINIDJE. CHORAGUS. 343 



a cinereous pubescence : antennae and legs rufous or rufo-castaneous : eyes 

 black. 



Abundant in old hedges near Ripley in June : it frequents trees 

 that are deeply enveloped in ivy, upon which it feeds in the larva 

 state : also found in the lane near Coombe-wood. " On a crab- 

 tree clothed with ivy, near Cobham, June, 1830." — A. Cooper, 

 Esq. : — who conceives that Cleonymus dispar is parasitic upon the 

 larva of this insect. 



Genus CCLVIII. — Choragus, Kirby. 



AntenncEVfiih the two basal joints incrassate; the third short, obconic ; the fourth 

 subelongate, cylindric ; the four following obconic ; the three terminal ones 

 suddenly longer ; the ninth and tenth being obconic, and the last nearly 

 ovate; the three forming a loose club. Palpi subsetaceous, the terminal joint 

 acute, and nearly subulated : mandibles acute: head indexed: clypeus elongate: 

 thorax convex : scutellum minute : body cylindric. 



Choragus is evidently allied to Cis, from which it differs not only 

 by having the two basal joints of the antennae incrassated, but by 

 the form of the body, which resembles that of a Cryptocephalus, the 

 subsetaceous palpi, acute mandibles, &c, and by the property the 

 living insect possesses of leaping considerably.
