37 RHYNCHOPHORA. 
Hab. Guaremata, Cerro Zunil, Zapote (Champron). 
Four specimens. An obscure species approaching C. sinuaticollis and its numerous 
allies, but with the femora armed with two rather widely separated teeth (the outer 
one minute, but distinct), the prothorax strongly transverse, the mesosternum sub- 
truncate (not hollowed) in front, &c. The stouter rostrum, the absence of the 
tubercles on the dise of the prothorax, the flat, mesially prominent mesosternum, &c., 
separate C. nigricans from C. crenatus. 
52. Conotrachelus fulvopictus, sp. n. 
Subovate, rather dull, varying in colour from nigro-piceous variegated with ferruginous to almost entirely 
ferruginous ; the vestiture sparse, fine, fulvous or ochreous, somewhat fasciculate on the elytra, con- 
densed into two short oblique streaks (placed one behind the other) on each side of the dise of the 
prothorax and a minute spot at each hind angle, the elytra also with a small condensed patch at the base 
of the third interstice and another on the shoulder, the femora with a whitish ring, the anterior pair 
with a fulvous line at the base above. Head closely punctate, a little flattened in front; rostrum 
cylindrical, stout, curved, not longer than the head and prothorax, rugulose and tricarinate, the apex 
sparsely punctate in the ¢ and a little smoother in the 9, the antennae inserted towards the tip, 
joint 2 of the funiculus slightly shorter than 1. Prothorax transverse, rounded at the sides anteriorly, 
constricted and narrowed in front, deeply bisinuate at the base; coarsely, rngosely punctate, and 
obsoletely carinate at the middle. Elytra about one-half wider than the prothorax, slightly compressed 
beneath the rounded humeri and narrowing from a little beyond this to the apex, the base deeply 
sinuate ; coarsely seriate-punctate, the interstices narrow, rugulose, 3, 5, 7, and 9 sharply costate, the 
ridge on 3 and 5 depressed or interrupted below the base, that on 3 sinuous beyond the middle and 
coalescent with that on 9 at the apex. Mesosternum flattened between the coxe, swollen on each side 
in front. Ventral segments sparsely punctate. Femora bidentate, the inner tooth long and sharp, the 
outer one small and placed at some distance from it. Tarsal claws with a moderately long tooth. 
Length 4-5, breadth 2-23 millim. (¢ 2.) 
Hab. Guatemata, San Gerénimo (Champion); Nicaragua, Chontales (Janson). 
Six specimens, all but one from Guatemala. In this insect the prothorax is very 
rugose, and has two short fulvous streaks (placed one behind the other) on each side 
of the disc, the dorsal coste of the elytra are interrupted or depressed below the base 
only, and the femora are distinctly bidentate, characters separating C. fulvopictus from 
C. sinuaticollis, C. germanus, and other allied forms. 
53. Conotrachelus flavangulus, sp. n. 
Conotrachelus flavangulus, Chevr. in litt. 
Subovate, slightly shining, nigro-piceous or piceous, the antenne and tarsi, and sometimes the tibie also, 
ferruginous ; the vestiture close, greyish or brown, somewhat mottled on the elytra and condensed into 
a broad, common, curved, indeterminate, pallid fascia beyond the middle, the prothorax with an oblique 
ochreous line on each side of the disc, extending forwards from the hind angles, the two lines nearly 
meeting at the apex and continued down the rostrum, the femora with a whitish ring, the elytra and 
legs feebly setulose. Head densely, rugulosely punctate, slightly depressed in front; rostrum stout, 
curved, not longer than the head and prothorax, densely rugulose, unicarinate, the apical portion a little 
smoother in the 2, the antenne inserted towards the tip, joint 2 of the funiculus shorter than 1,
