prominence placed at some distance exterior to it; posterior tibie in the ¢ hollowed and ciliate at the 
apex within and abruptly unguiculate ; tarsal claws with a short fine tooth. 
Length 53-63, breadth 2,933 millim. (¢ 2.) 
Hab. GuatEMALA, Panzos in Vera Paz (Champion); Panama, Bugaba, David 
(Champion).—VENEZUELA (Mus. Dresden). 
Numerous examples, all from the “ tierra caliente.” A well-marked species, with a 
very rugose, carinate, almost bare prothorax (the fine sete excepted), and cordate, 
setulose elytra, the alternate interstices of which are sharply carinate throughout. In 
the ventrally exposed pygidium of the male it agrees with C. lateralis, but these two 
species are not otherwise related. 
112. Conotrachelus squamifrons, sp.n. (Tab. XX. fig. 15, abdomen, ¢.) 
Subovate, rather dull, black or piceous, the elytra and legs more or less mottled with obscure ferruginous, the 
antenne (the club excepted) and the tip of the rostrum of the same colour; the vestiture sparse, fulvous, 
closer and fasciculate on the elytra, the head with a transverse, almost divided, dense fulvous patch in 
front, the prothorax with a small fulvous spot or faint oblique line on each side of the disc and a minute 
spot at each hind angle, the elytra also with a small fulvous patch at the base of the third interstice and 
another on the shoulder, the femora with a whitish or ochreous ring, the anterior pair with a fulvous line 
at the base above; the upper surface and legs also set with short, fine, pallid, semierect sete. Head 
transversely depressed and rugulosely punctate in front; rostrum moderately stout, arcuate, about as 
long as the head and prothorax, 5-carinate, sparsely punctate at the tip, the antenne in the ¢ inserted 
towards the apex, and in the 2 at about one-fourth from it, joints 1 and 2 of the funiculus equal in 
length. Prothorax transverse, rounded at the sides anteriorly, constricted and narrowed in front, deeply 
bisinuate at the base ; coarsely, rugosely punctate, and sharply carinate to near the base. Elytra cordate 
or oblong-cordate, about one-half wider than the prothorax ; coarsely seriate-punctate, the interstices 
rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 sometimes interrupted below the base. Meso- 
sternum hollowed in the middle in front. Ventral segments coarsely, closely punctate, 5 sinuato-truncate 
at the apex in the ¢, the pygidium narrowly exposed in this sex. Femora clavate, moderately or feebly 
unidentate, the tooth sometimes very short in the ¢. Posterior tibia in the ¢ ciliate at the apex within 
and abruptly unguiculate. Tarsal claws with a short fine tooth. 
Length 43-5, breadth 23-24 millim. (¢d Q.) 
Hab. Guaremaua, Cerro Zunil, Volcan de Atitlan, Zapote (Champion); Panama, 
Bugaba, Volcan de Chiriqui (Champion). 
Found in numbers at Zapote, sparingly elsewhere. A small form of C. brevisetis, 
with a dense, transverse, almost divided, patch of fulvous scales on the front of the 
head, the femora without trace of an additional prominence, the pygidium more narrowly 
exposed in the male, &c. The femoral tooth is sometimes quite small, especially in 
the male. C. naso, Lec., from Georgia and Texas, approaches the present. species.
