‘400 RHYNCHOPHORA. 
about the middle, and deeply excavate and ciliate at, the apex, the claw long. Tarsal claws with a 
long tooth. 
Length 43-54, breadth 2j-23 millim. (¢-) 
Hab. Panama, David, Caldera (Champion). 
Two males. This is one of several forms with the ridge on the third elytral 
interstice interrupted below the base and strongly sinuate beyond the middle. The 
vestiture of the elytra is rather close, and not condensed into spots at the base, that on 
the prothorax being condensed into two faint oblique lines on the disc. The shape 
of the hind tibie is characteristic. 
106. Conotrachelus fulvibasis, sp. n. 
Very like C. sinuatocostatus (infra), but with the rostrum cylindrical; the prothorax less transverse, very 
coarsely, confluently punctate and also carinate, with, at most, a short, faint, condensed, whitish or fulvous 
line midway between the carina and outer margin; the elytral interstices smoother, the ridge on 3 
depressed or interrupted below the base ; the femora with a sharp triangular tooth, and a very minute 
prominence a little exterior to it; the posterior tibia feebly sinuate within in both sexes ; the vestiture 
of the elytra condensed and fulvous in colour at the base, very sparse, subfasciculate, and intermixed 
with whitish thence to the apex. 
Length 44-52, breadth 23-3 millim. (d 2.) 
Hab. Mexico, Teapa (H. H. Smith); Guatemata, Zapote, Senahu (Champion 
Panama, Volcan de Chiriqui (Champion). | 
Four specimens, apparently belonging to one species; the description is taken from 
the examples from Teapa and Zapote. 
107. Conotrachelus rufescens, sp. n. 
Oblong-ovate, rather narrow, shining, rufo-piceous, the suture and under surface darker, the head and rostrum 
ferruginous; the vestiture rather coarse, sparse, ochreous, that on the prothorax condensed into a curved 
line on each side of the disc and a minute spot at each hind angle, and that on the elytra fasciculate, 
becoming more condensed at the base of the third interstice, on the shoulders, and at the apex, the femora 
biannulate. Head closely punctate, faintly foveate between the eyes ; rostrum moderately stout, feebly 
curved, a little longer than the head and prothorax, tricarinate at the base, almost smooth in its apical 
half, the antenne inserted at about one-third from the tip, joints 1 and 2 of the funiculus subequal in 
length. Prothorax transverse, a little rounded at the sides, narrowed and compressed in front, moderately 
bisinuate at the base; closely, confluently punctate, and also carinate anteriorly. LElytra about one-half 
wider than the prothorax, subparallel at the base; seriate-punctate, the interstices narrow and finely 
rugulose, 3, 5, 7, and 9 costate, the ridge on 3 depressed below the base and sinuate beyond the middle. 
Intermediate coxe rather narrowly separated. Mesosternum flattened, binodose in front. Ventral 
segments sparsely punctate. Femora clavate, each with a sharp triangular tooth, and a very minute 
prominence exterior to it. Anterior tibie strongly, the others feebly, sinuate within. Tarsal claws 
with a moderately long tooth. 
Length 44, breadth 21, millim. (@.) 
Hab. Panama, Bugaba (Champion). 
One specimen. Not unlike C. fulvopictus, but with the rostrum (@ ) less curved, 
smoother, and not so stout; the vestiture coarser, condensed into a curved line on each
