CONOTRACHELUS. 435 
slightly intermixed with white on the elytra, that on the legs similarly coloured, the femora obsoletely 
annulate, the anterior pair with a conspicuous fulvous streak along their basal half above; the upper 
surface and legs also set with short, scattered, semierect, pallid sete. Head rugulosely punctate, 
transversely depressed, carinate, and binodose in front; rostrum stout, arcuate, about as long as the 
prothorax, shining, 5-carinate, the median carina short, thickly punctate at the tip, the antenne inserted 
near the apex, joints 5-7 of the funiculus shorter than 3 and 4, 2 elongate, a little longer than 1. 
Prothorax large, broader than long, transversely convex, rounded at the sides, strongly constricted and 
much narrowed in front, deeply bisinuate at the base, and emarginate at the apex; coarsely, shallowly, 
confluently punctate, the interspaces shining and here and there obliquely raised or granulate, four of the 
prominences on the middle of the disc and two at the apex being more conspicuous than the rest, the 
dise also carinate anteriorly. LElytra somewhat cordate, about one-third wider than the prothorax, 
deeply sinuate in front; coarsely seriate-punctate, the interstices finely and sparsely seriato-granulate, 
3, 5, 7, and 9 sharply costate, 10 also costate at the base, the ridge on 3 shortly interrupted anteriorly, 
and that on 7 and 9 each produced at the apex into a short spine. Intermediate cox widely separated. 
Rostral canal smooth, deep, reaching the anterior portion of the metasternum, the mesosternum conically 
protuberant on each side in front. Ventral segments sparsely, finely punctate. Legs very stout and 
rugose; femora strongly clavate, bidentate, the outer tooth small; anterior and intermediate tibie 
strongly, and the posterior pair feebly, sinuate within ; tarsal claws with the inner tooth nearly as long 
as the claw itself. 
Length 62, breadth 32? millim. (¢?) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen. Differs from all its allies in the quadrispinose apical declivity of the 
elytra.

Conotrachelus sobrinus, Boh. in Schénh. Gen. Cure. iv. p. 453°. 
Conotrachelus gerstaeckeri, Jekel, in litt.’ 
Subovate, robust, arched above (as seen in profile), shining, black, the elytra rufo-piceous, with a transverse 
patch at the middle of the suture and a smaller one between it and the apex black, the tip of the 
rostrum, the antenne, and the legs in part (the base of the femora excepted) reddish ; the vestiture of 
the elytra dense, greyish- or reddish-brown, the head with a large, dense, whitish or fulvous patch 
in front, enclosing two minute bare prominences, the clothing of the prothorax, rostrum, and under 
surface very sparse, that of the legs and coxe closer, fulvous or white, the prothorax with two very small 
condensed whitish spots on the disc and sometimes another on each side, the femora faintly annulate, the 
anterior pair with a fulvous streak at the base; the upper surface also set with numerous short, semierect, 
pallid, stiff setee, and the seriate elytral punctures each with a narrow whitish scale, the legs setulose. 
Head densely punctate, transversely depressed in front ; rostrum moderately stout, arcuate, about as long 
as the head and prothorax, gibbous at the base above, sharply 5-carinate, the apex sparsely punctate, 
much smoother throughout in the 9, the antenne inserted near the tip in the ¢, and further back in 
the 9, joints 1 and 2 of the funiculus equal in length. Prothorax a little broader than long, narrowed 
and constricted in front, deeply bisinuate at the base; very coarsely, confluently punctate, and also 
carinate. Elytra rather long, subtriangular, convex above, deeply sinuate at the base, the humeri 
rounded; seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 sharply, uninterruptedly costate, 
Rostral canal somewhat abruptly terminating in the front of the metasternum. Ventral segments 
sparsely, coarsely punctate. Femora clavate, unidentate. Tarsal claws with the inner tooth nearly 
ag long as the claw itself. 
Length 53-63, breadth 3-33 millim. (d 9.)
