CONOTRACHELUS. 429 
158. Conotrachelus dentimanus, sp. n. (Tab. XXI. figg. 15, 15a, 3; 154, 
anterior leg.) 
Ovate, robust, dull, nigro-piceous, the antenne in part and the tips of the tarsi reddish ; the vestiture rather 
sparse, rusty-red, subfasciculate on the elytra, the head with a large white patch in front, the prothorax 
with two minute white spots on the disc and one at each hind angle, the elytra also mottled with white, 
the femora with a whitish annulus, the anterior pair with a narrow fulvous line along their basal half 
above; the upper surface and legs also set with short, scattered, semierect sete. Head rugulosely 
punctate, broadly, transversely depressed and feebly binodose in front; rostrum moderately stout, curved, 
a little longer than the prothorax, shining, sharply 5-carinate, thickly punctate at the tip, the antenne 
inserted towards the apex, joint 2 of the funiculus much longer than 1. Prothorax transverse, rounded 
at the sides, strongly constricted and much narrowed in front, deeply sinuate at the base, densely, finely, 
rugulosely punctate, and also sparsely, rather coarsely granulate, the dise with indications of a short 
median carina. Elytra subtriangular, about one-half wider than the prothorax, deeply sinuate in front, 
the humeri rounded ; coarsely seriate-punctate, the interstices very sparsely and finely seriato-granulate, 
3, 5, 7, and 9 sharply costate, the ridge on 3 shortly interrupted below the base. Intermediate coxe 
distant. Mesosternum concave, protuberant on each side in front. Metasternum feebly depressed along 
the middle, smooth in front. Ventral segments coarsely, rather closely punctate, 1 depressed in the 
centre. Legs stout and rugose; femora clavate, bidentate, the outer tooth small, but prominent; tibixe 
strongly sinuate within, the anterior pair angularly dilated at about the middle; tarsal claws with a 
short, acute tooth. 
Length 7, breadth 33 millim. (¢.) 
Hab. Panama, Caldera in Chiriqui 1200 feet (Champion). 
One specimen. ‘The dense white patch on the front of the head, the sparsely 
granulate prothorax, the sides of which are rounded from the base, the angularly 
dilated anterior tibize, and the distinctly bidentate femora, separate C. dentimanus 
from C. curvimanus and others. 
159. Conotrachelus tenuipes, sp. n. 
Ovate, robust, dull, nigro-piceous, the antenna, the tip of the rostrum, and the apices of the tarsi reddish; the 
vestiture fine, rather close above, very sparse beneath, rusty-red, the elytra slightly mottled with whitish, 
the femora faintly annulate; the upper surface and legs also set with short, semierect sete. Head 
densely, rugulosely punctate, transversely depressed in front ; rostrum comparatively slender, arcuate, a 
little longer than the head and prothorax, shining, sharply 5-carinate, thickly punctate at the tip, the 
antenne inserted towards the apex, joint 2 of the funiculus slightly longer than 1. Prothorax transverse, 
abruptly narrowed and constricted in front, deeply bisinuate at the base; densely, rugulosely punctate, 
the narrow shining interspaces here and there obliquely raised or granulate, the disc with indications of 
an abbreviated median carina. LElytra somewhat cordate, rather more than one-half wider than the 
prothorax, deeply sinuate in front; seriate-punctate, faintly striate towards the suture, the interstices 
3, 5, 7, and 9 narrowly, uninterruptedly costate. Mesosternum concave, smooth, protuberant on each 
side in front. Metasternum slightly depressed down the middle. Ventral segments 1-4 coarsely and 
rather closely, and 5 densely, punctate. Legs comparatively elongate, rugose ; femora somewhat linear, 
the anterior pair unidentate, the others sharply bidentate ; anterior tibiz sinuous within; tarsi rather 
slender, the claws with a short, acute tooth. 
Length 63, breadth 383 millim. (<3?) 
Hab. Costa Rica, Volcan de Irazu (fogers). 
A single example. A species with comparatively elongate legs, unequally dentate 
femora, irregularly granulate prothorax, uninterrupted elytral carine, and coarsely 
punctured abdomen, its nearest allies being C. dentimanus and C. longidens.
