434 RHYNCHOPHORA. 
168. Conotrachelus incanus, sp. n. (Tab. XXI. figg. 20, 20a, ¢.) 
Rather elongate, subrhomboidal, rufo-piceous, the antenne and the tips of the tarsi ferruginous; above and 
beneath densely, uniformly clothed with minute yellowish-cinereous scales, and with very short, fine, 
scattered, decumbent sete. Head densely punctulate; rostrum (d ) slender, feebly curved, considerably 
longer than the head and prothorax, finely punctate and squamose at the base, for the rest bare and 
almost smooth, the apical portion a little widened, (Q ) very slender, smooth, and cylindrical, twice as 
long as the prothorax, the antenne inserted at about one-third from the tip in the male and at the middle 
in the 2, joints 1 and 2 of the funiculus elongate and subequal. Prothorax short, conical, strongly 
bisinuate at the base, compressed at the sides in front; sparsely punctate, the interspaces closely, minutely 
punctate. Elytra elongate-triangular, one-half wider than the prothorax, flattened on the disc anteriorly, 
the humeri obliquely truncate in front; seriate-punctate, the punctures well-separated, the interstices 
finely rugulose, 3, 5, 7, and 9 feebly costate towards the apex, 7 and 9 also more or less costate at the 
base, 3 with a short, prominent, abruptly terminated ridge a little beyond the middle in the @, this 
being almost obsolete in the Q. Mesosternum concave between the coxe, the sides nodose in front. 
Metasternum depressed down the middle. Ventral segments closely, finely punctulate. Femora clavate, 
acutely unidentate. Tarsal claws with a very long tooth. 
Length 6-64 breadth 3-32 millim. (d 2.) 
Hab. Guaremata, San Gerénimo in Vera Paz 3000 feet (Champion). 
‘Three specimens, in a perfect state of preservation. A very peculiar species, nearly 
allied to C. serpentinus, but easily distinguishable by the uniform, dense, yellowish- 
cinereous vestiture, the short, conical prothorax, the very slender smooth rostrum of 
the female, &c. | 
169. Conotrachelus sulcipectus, sp. n. 
Subovate, robust, shining, rufo-piceous, darker beneath, the antennw ferruginous ; the vestiture close, rather 
short, almost entirely fulvous, very sparse on the abdomen. Head densely punctate; rostrum rather 
slender, feebly curved, longer than the head and prothorax, rugulosely punctate and striate at the sides, 
unicarinate at the base, the apex minutely, very sparsely punctate, the antenne inserted at about one- 
third from the tip, joints 1 and 2 of the funiculus elongate, equal in length. Prothorax transverse, 
subconical, strongly constricted in front, deeply bisinuate at the base ; densely, very finely punctate, with 
‘scattered coarse punctures intermixed, sharply carinate. Hlytra subtriangular, rather more than 
one-half wider than the prothorax, the humeri rounded ; coarsely seriate-punctate, the interstices broad, 
rugulose, 7 and 9 costate throughout, 3 costate at the apex and 5 from about the middle onwards. 
Meso- and metasternum hollowed down the middle, the latter short. Ventral segments 1 and 2 coarsely, 
and 3-5 more finely, punctate, the punctuation very sparse on 3 and 4. Femora clavate, unidentate, 
sulcate beneath. Tarsal claws with a moderately long tooth. 
Length 7, breadth 3,8, millim. (@.) 
Hab. Nicaraaua, Chontales (Belt). 
One rather worn specimen. Less elongate than C. serpentinus, the elytra shorter 
and broader, the prothorax sharply carinate, densely, finely punctate, with scattered 
coarse punctures intermixed, the meso- and metasternum more hollowed down the 
middle, the latter short. 
170. Conotrachelus spinipennis, sp.n. (Tab. XXI. figg. 21, 21 a.) 
Broad-ovate, very robust, rather dull, black, the antenne and the tips of the tarsi obscure ferruginous ; the 
vestiture moderately close above, very sparse beneath, ferruginous, becoming denser, subfasciculate, and
