CAMPTODES. 345 
Club of the antenne moderately broad. Head and disc of the thorax extremely 
finely punctate; elytra sparingly punctate, more or less brown at the extremity. 
Pygidium sparingly and not coarsely punctate. 
In this species the sexual differences are considerable: the female has the terminal 
portion of each elytron rounded and obliquely truncate inwardly behind the termination 
of the suture; in the male each apex is separately rather strongly rounded. The large 
males have the thorax and elytra quite dull and their sculpture obliterated. 
Hight specimens.

Had. Panama, Volcan de Chiriqui (Champion). 
Antenne with the club red, only moderately broad. Head finely punctate, red, with 
the summit of the vertex frequently infuscate. Thorax only very sparingly and finely 
punctate. Elytra sparingly punctate. Pygidium black, shining, sparingly punctate. 
In the male the thorax and elytra are either dull, or shining as in the female, and the 
apex of each elytron is separately rounded ; in the female each elytron has the apex 
produced so as to form a rounded prominent process. In the female sex the last ventral 
segment has a broad, depressed, shining space extending longitudinally along the middle. 
A large series has been received of this species, and, except in the stature and 
sculpture of the males, it scarcely varies at all; the summit of the vertex is, however, 
sometimes distinctly, sometimes scarcely at all, black. 
45. Camptodes signaticollis, sp. n. 
Rotundato-ovalis, parum convexus, rufo-testaceus, vertice, prothoracis medio, elytris, pectore abdomineque 
nigTis. 
Long. 34-4 millim. 
Hab. Panama, Bugaba, Caldera (Champion). 
Head and thorax finely punctate, the latter with a broad dark longitudinal mark 
on the middle, the former with the vertex blackish ; club of the antenne clear red, 
moderately large. Elytra rather coarsely punctate. In the male the thorax and 
elytra are more or less dull, and the apices of the elongate elytra are much rounded, 
the inner part of the curve being somewhat truncate. In the female the surface is 
shining, and the elytra are dehiscent at the apices, which form each an obtuse angle, 
the hind margin being very slightly sinuate; the apex of the last ventral segment in 
this sex is shining in the middle and very feebly raised.
