410 RHYNCHOPHORA. 
125. Conotrachelus parvulus, sp. n. 
Subovate, narrow, rather convex, shining, rufo-piceous, more or less mottled with black, the antenne ferru- 
ginous ; the vestiture sparse, fine, whitish, condensed into small scattered patches on the elytra (including 
one at the base of the third interstice and another on each shoulder), the latter also with an irregular 
series of semierect white setze down each interstice. Head densely punctate, finely foveate between the 
eyes; rostrum short and very stout, about as long as the prothorax, rugosely punctate and unicarinate, 
the antenne inserted near the tip, joints 4-7 of the funiculus transverse, 2 a little shorter than 1. 
Prothorax transverse, convex, rounded at the sides anteriorly, constricted and narrowed in front, feebly 
sinuate at the base; densely, rather coarsely punctate. Elytra one-half wider than the prothorax, narrow- 
ing from a little before the middle, the humeri obtuse, somewhat obliquely truncated in front ; coarsely 
punctate-striate, the punctures subquadrate and closely placed, the interstices not wider than the stria, 
closely rugulose, equally convex throughout. Ventral segments densely, coarsely punctate. Mesosternum 
simply flattened between the cox. Legs rather short; femora finely unidentate; tibiae strongly sinuate 
within ; tarsal claws with a very short tooth. 
Length 3, breadth 14 millim. (¢ 2.) 
Hab. GuateMaLa, Champerico (Champion). 
Two specimens, from the Pacific coast, the one assumed to be the male having 
stouter legs than the other. A small, rather convex form, with relatively narrow 
elytra, the interstices of the latter not wider than the strize and equally convex 
throughout. It approaches C. lineatus. 
126. Conotrachelus adustus, sp.n. (Tab. XX. figg. 23, 23 a, 2.) 
Subovate, broad, nigro-piceous, the antenn, the tip of the rostrum, and the tarsi ferruginous; the vestiture 
dense, pale brown, slightly intermixed with white and dark brown, the dark brown scales condensed into 
three vittz on the prothorax, an irregular, transverse, undulate fascia at about the middle of the elytra, 
and a faint fascia towards the apex, the upper and under surfaces and the legs also clothed with short, 
scattered, white, decumbent, fine sete, the femora obsoletely annulate. Head densely, finely punctate ; 
rostrum nearly twice as long as the prothorax, moderately stout, curved beyond the middle, squamose and 
densely rugulose, the apical portion bare and thickly punctate, the antenne inserted at about one-third 
from the apex in the ¢ and nearer the base in the 2, joint 1 of the funiculus much longer than 2. 
Prothorax small, transverse, abruptly narrowed in front, the sides parallel behind, the base feebly 
bisinuate ; densely, finely punctate. Elytra nearly twice as wide as, and more than three times the 
length of, the prothorax, subparallel in their basal third, the humeri rounded in front; seriate-punctate, 
the interstices broad, densely rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 twice interrupted 
and the median elevation prominent, that on 5 slightly interrupted below the base. Mesosternum flat- 
tened between the coxa, declivous in front. Ventral segments, except at the sides, sparsely, finely 
punctate. Femora clavate, rather feebly unidentate. Tarsal claws each with a long curved tooth arising 
from the base, the two teeth nearly meeting at the tip. 
Length 53-63, breadth 3-34 millim. (¢ 2.) 
Hab. Guatema.a, Capetillo, Duefias (Champion). 
One pair, the female with the intermixed white scales more abundant than in the 
male, the latter having the dark brown elytral markings more distinct. This insect 
somewhat resembles C. dentiferus, Fahr. The tarsal claws are formed almost as in 
the North-American C. jissunguis, Lec. The dense vestiture hides the surface- 
sculpture.
