640 RHYNCHOPHORA. 
pair longer and more robust than the others; femora more or less clavate, unidentate, the anterior pair 
with a long tooth and a small denticle exterior to it; tibia compressed and carinate, somewhat arcuate 
externally. 
Length 63, breadth 23 millim. (9?) 
Hab. Panama, Bugaba (Champion). 
One specimen. In this species the sides of the elytra (as seen from above) form an 
almost continuous outline with those of the prothorax, the vestiture is uniform and 
rather sparse (without intermixed sete), the anterior legs are robust, &c. An isolated 
form. 
Species moderately large, oblong-ovate, very densely squamose and coarsely setose, with the eyes 
distant, the rostrum feebly arcuate, slightly widened towards the tip, the antenne inserted 
behind the middle of the rostrum, the club ovate, the prothorax bisinuate at the base, the 
elytra a little wider than the prothorax, with the third interstice swollen at the base, 
the mesosternum broad, prominent, shallowly emarginate, the metathoracic episterna 
moderately broad, the ventral segments 2-4 subequal in length, the femora, at most, 
obsoletely dentate, the anterior tibiz and tarsi ciliate in the male. (No. 18.)

Hab. Mexico, Playa Vicente and Toxpam in Vera Cruz (Sallé: ¢ 2 ); Nicaragua, 
Chontales (Janson: 2 ).—Braziu}. 
Six specimens, the two males from Vera Cruz agreeing very well with Boheman’s 
description of this peculiar species, recognizable at a glance by the strongly and densely 
ciliate anterior tibiee of the male. The vestiture is very dense above and beneath, and 
somewhat variable in colour, and the erect, blunt sete are coarse and spiniform. The 
prothorax has a subquadrate brownish patch or two triangular black spots on the disc 
at the base. The elytra have a brown patch on each side of the scutellum, a common, 
interrupted, outwardly widened, similarly-coloured median fascia, and several black 
spots, these latter scattered along the suture, sides, and base; the second interstice is 
slightly raised. The rostrum of the male is rugosely punctate to the tip, that of the 
female finely punctate and bare to near the base; the antenne are inserted behind 
the middle in both sexes, The anterior tarsi of the male have a few projecting 
hairs. The femora are obsoletely unidentate, the anterior pair sometimes unarmed, 
and, like the tibie, they are often incompletely annulate with black. The length 
varies from 54-74 millim. C. plumtpes should perhaps form the type of a separate 
genus. It cannot be retained in Gasterocercus, the type of which is G, depressirostris 
(Fabr.).
