Hob. Panama, Chiriqui. 



The specimen reserved for the " Biologia " collection 

 is the male labelled by Gorham as the type. The antennal 

 joints 4-10 are acutely serrate, as in the female of D. opacus. 

 D. decipiens has the elytra closely, rather coarsely punctate, 

 and shining.

•Hab. Nicaragua, Chontales. 



The unique type of this insect appears to be a female. It 

 has the general facies and colour of a spotted Collops. The 

 antennal joints 5-10 are moderately widened and serrate. 

 The marginal fold of the elytra is very conspicuous. 



6. Dromanthus jucundus.

Hab. Panama, Chiriqui. 



There are five specimens of this remarkable insect in the 

 " Biologia " collection, probably all females, to judge from 

 their comparatively small head, short, sharply serrate 

 antennae, and simple posterior tarsi.

The type {(^) of this genus, H. aurivillus, Gorh., is closely 

 related to Trichochrous (sensu Casey), differing from it in 

 the less prominent humeri and the oblong-ovate general 

 shape of the body, this being especially noticeable in the 

 male. The antennae have the five outer joints widened 

 into a definite club, as in T. femoralis (Gorh.), and the 

 tibiae are as closely and strongly spinulose as in T. arcuati- 

 collis and its alhes. The female of H. serripes has the 

 general facies of a Byturus.
