of Anthocomus. The larger species (opacus) is in form very like Collops, which it was 
placed with in the Sallé collection. 
1. Dromanthus opacus. 
Niger vix nitidus; ore, epistomate, thoracisque lateribus late rufis; elytris opacis, fumosis, lineis duabus 
abbreviatis elevatioribus. Long. 6 millim. 
Hab. Mexico, Playa Vicente (Sallé). 
This insect has very much the appearance of a Collops; but its colours are unlike 
those of the members of that genus. It is entirely smoky black, with the front of the 
head, the sides of the thorax, the coxee, and trochanters of the anterior and middle legs 
red. The antenne are acutely serrate from the fourth to the tenth joint, the third joint 
being angular internally. The basal joint is yellow beneath. ‘The palpi have their 
apical joint oval, but a little truncate. 
A single specimen of this is all I have seen. 
2. Dromanthus decipiens. (Tab. VII. fig. 5.) 
Niger, nitidus ; prothoracis lateribus lete rufis. Long. 43 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This species is allied to D. opacus; but it is smaller, and the elytra especially are more 
shining. These latter are distinctly punctured, the smaller and larger punctures very 
irregularly mixed. The thorax is very even and orbiculate, wider than long, being 
broadly truncate in front. The erect hairs are very sparingly present. ‘The basal and 
one or two succeeding joints of the antenne are spotted with pitchy red beneath. The 
fourth to tenth joints are acutely serrate. The coxe and trochanters of the first two 
pairs of legs and the margins of the basal four ventral plates are yellowish. 
Two specimens, one of which at least is a male, present no important difference. 
This species is coloured almost precisely as Anthocomus plagiatus, and as a Clerid of 
the genus Colyphus also. 
8. Dromanthus quadrimaculatus. (Tab. VII. fig. 4.) 
Rufo-ferrugineus, nitidulus ; antennis, pedibus, elytrorumque maculis duabus (una basilari quadrata, altera sub- 
apicali lunata) nigris. Long. 4% millim. 
Hab. Nicaragua, Chontales (Janson). 
This is a very different-looking species from either of the preceding, both in colour and 
in having the thorax rather smaller in proportion to the elytra, and the head rather more 
produced in front. The chief characters are, however, the same: only four joints can 
be distinguished in the tarsi; the antenne are serrate, their basal joints are reddish 
beneath. 
A single specimen.
