I cannot distinguish Z. ravidus from E. aurifer, which I look upon as a variable 
species like several others of the genus. The type of £. aurifer sent by Dr. Aurivillius 
from Schénherr’s collection is an example of the most coarsely sculptured form of the 
species as known to me. I have not seen any typical example of Z. ravidus, which was 
described from Germar’s collection, but I have very little doubt it will prove to be the 
more thickly scaled and finely punctured form of this species. 
35. Epicerus amula, sp. n. 
Convexus, niger, subnitidus, subnudus ; prothorace in medio longitudinaliter bi-impresso ; elytris punctis grossis 
impressis, interstitiis alternis vix magis elevatis, ad latera prope humeros minus parce squamosis. 
Long. 10 millim. 
Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith), Cuernavaca (Hége), 
Mexico city (Schumann). 
Rostrum somewhat closely punctate, broadly but not deeply impressed on the 
middle, with an obsolete channel (rather more distinct in the female than in the male) 
in the depression; lateral impression moderately large; the fovea on the forehead 
distinct. ‘Thorax elongate, subconical, finely punctate, very sparingly squamose, with a 
vague depression on the middle interrupted just on the disc. Elytra with series of 
very large punctures, the alternate interstices but little raised, the one proceeding from 
the shoulder is, however, quite distinct, and outside it, near the shoulder, there is an 
accumulation of pallid scales. ‘The squamosity is less scanty on the apical parts of the 
elytra; and the under surface is almost covered with scales. Two specimens. 
This species is similar to some of the varieties of &. aurifer; but it has a much 
longer thorax, and larger punctures on the elytra. 
36. Epicerus lateralis, sp.n. (Tab. V. fig. 13.) 
Angustus, convexus, niger, subnudus ; elytro singulo vitto laterali pallide flavo-squamoso. 
Long. 11 millim. 
Hab. Mexico, Amula in Guerrero 6000 feet (1. H. Smith). 
Head and rostrum shining black, rather sparingly punctate; the front of the latter 
somewhat depressed along the middle; the depression in the male broad, shallow, and 
scarcely canaliculate, in the female more elongate, narrow, and vague, but very distinctly 
canaliculate; lateral impression short, placed near the eye; a fovea on the forehead. 
Thorax conico-cylindrical, nearly bare on the upper aspect, squamose on the flanks ; 
sparingly and finely punctate, very feebly longitudinally depressed along the centre, 
the depression interrupted in front of the middle and not reaching the base. Elytra 
narrow and subcompressed, with a series composed of paired, nearly confluent, coarse
