140 RHYNCHOPHORA. 
This species varies a great deal in size, and considerably in form and sculpture ; the 
base of the elytra is more emarginate in some examples, so that the shoulders are more 
acuminate and prominent in front. 
21. Epagrius grandis, sp.n. (Tab. VI. fig. 4.) 
Major, latus, niger, opacus, rugosus, squamulis minutis parcius vestitus, capite supra oculos transversim 
depresso. 
Long. 18 millim. 
Hab. Mexico, Mochitlan in Guerrero (Baron). 
Rostrum parallel, deeply canaliculate along the middle, the channel extending to the 
transverse depression at the back of the head; lateral impressions deep, slender; eyes 
quite prominent. Thorax very coarsely rugose, canaliculate along the middle; the sides 
nearly straight from the base to near the front, then very abruptly narrowed. Elytra 
very broad, convex, nearly twice as broad as the thorax; sculptured with very large 
vague depressions, the interstices between these very irregular and indistinct, the third 
more raised than the others for the greater part of its length, the fifth and seventh 
also somewhat raised; the surface studded with minute granules, and also with very 
small, squalid scales. Hind tibie furnished at the apex with a slender mucro, con- 
cealed by a tuft of hairs. 
I have seen only one specimen of this very distinct species. 
CACOCHROMUS, gen. nov. 
Scrobes lateraliter site, curvate, late, oculum vix attingentes. Antenne scapo sat elongato, prothoracis 
marginem anteriorem attingente. 
It is necessary to separate Hpicerus carteri, Chevr., from Hpicwrus as here treated. 
The scrobes are broad, and do not quite reach the eye, and the scape is longer than it 
is in any Epicerus. 
1. Cacochromus carteri. (Tab. VI. fig. 6.) 
Epicerus carteri, Chevr. Bull. Soc. Ent. Fr. 1880, p. Ixii*. 
Hab. Guatemaa} (Sallé), Escuintla (Conradt) ; Costa Rica (van Patten). 
We have received five examples of this conspicuous insect. Both sexes appear to 
be represented, and if so the male differs from the female only by being rather more 
slender and parallel. 
BRADYRHYNCHUS, gen. nov. 
tostrum brevissimum, medio haud impressum; oculi convexi. Tarsi parvi; tibiz posteriores truncatura 
apicali parva, extus simplices nullo modo incrassate, angulo inferiore mucrone tenui armato. 
This genus is proposed for three species, which it is better to separate from Epicerus
