402 RHYNCHOPHORA. 
110. Gonotrachelus obliquelineatus, sp.n. (Tab. XX. figg. 13, 13 a, 3.) 
Subovate, moderately shining, rufo-piceous above, darker beneath, the prothorax with a small space on the 
dise at the base, and the elytra with an ante-median fascia and the apex black or piceous, the antenne 
and legs in great part ferruginous; the vestiture exceedingly fine, very sparse, ochreous, the prothorax 
with two condensed oblique lines of coarser, narrow scales on each side of the disc—the inner lines 
confluent at the middle and almost enclosing a small, narrow, bare space behind, these markings continued 
forwards as a single stripe down the head and rostrum, and backwards on to the base of the alternate 
interstices of the elytra,—the latter also with an irregular, condensed, angulated fascia of coarser whitish 
or ochreous scales at the apex, the clothing of the under surface very sparse and whitish, the femora 
biannulate. Head densely punctate; rostrum very stout, curved, about as long as the head and prothorax, 
rugulose and carinate, sparsely punctate at the tip, a little smoother in the 2, the antenne inserted 
towards the apex, joint 2 of the funiculus shorter than 1. Prothorax narrow, nearly as long as broad, 
narrowed and slightly compressed in front, moderately bisinuate at the base; densely punctate, the disc 
with two small prominences about the middle and sometimes very finely carinate anteriorly. LElytra 
oval, rapidly narrowing from about the basal third, sinuate in front, the humeri rounded; coarsely 
seriate-punctate, the punctures subquadrate, the interstices densely rugulose, 3, 5, 7, and 9 strongly and 
very sharply costate, the ridge on 3 abruptly interrupted beyond the middle. Mesosternum flattened 
between the coxe, somewhat protuberant in front. Ventral segments very sparsely, finely punctate. 
Legs rather elongate; anterior femora feebly or obsoletely, the others distinctly, unidentate ; tarsal claws 
with a short tooth. 
Length 34-34, breadth 14-2 millim. (d 2.) 
Hab. Panama, Bugaba (Champion). 
Three specimens. A peculiar little species somewhat resembling C. anaglypticus, 
but with the markings of the prothorax very different (the oblique lines being placed. 
on the disc, instead of at the sides), and the two carine in front absent, the elytra 
rapidly narrowing from about the basal third, the coste much more prominent, the 
first abruptly interrupted beyond the middle. 
111. Conotrachelus brevisetis, sp. n. (Tab. XX. figg. 14, lta, 3 ; 144, 
abdomen, ¢; 14 ¢, hind leg, ¢.) 
Subovate, shining, black, the elytra and legs usually mottled with rafo-piccous, the antenne and tip of the 
rostrum also reddish ; the vestiture very scattered, fulvous, condensed into two small spots on the middle 
of the disc of the prothorax, one at each hind angle of the latter, and numerous others on the elytra, one 
at the base of the third interstice being conspicuous, the femora annulate at the middle, the anterior pair 
with a fulvous line at the base above, the narrow scales on the under surface whitish ; the upper surface 
and legs also set with numerous short, fine, semierect, ochreous or whitish sete. Head densely, rugosely 
punctate, transversely depressed above the eyes, the front with a short median carina and a small 
tubercle on each side of it; rostrum moderately stout, arcuate, considerably longer than the head and 
prothorax, sharply 5-carinate, sparsely punctate at the tip, the antenne in the ¢ inserted near the apex, 
and in the Q at about one-fourth from it, joints 1 and 2 of the funiculus equal in length. Prothorax 
transverse, rounded at the sides anteriorly, constricted and narrowed in front, deeply bisinuate at the 
base ; very coarsely, confluently punctate, and also sharply carinate to near the base. Elytra cordate, 
seriate-punctate, the punctures towards the suture placed in shallow strie, the interstices rugulose, 
3, 5, 7, and 9 sharply costate throughout. Mesosternum flattened between the coxe, hollowed in the 
middle and nodose on each side anteriorly. Ventral segments coarsely, rather sparsely punctate, 
5 sinuato-truncate at the apex in the ¢, the pygidium exposed and becoming ventral in this sex. Legs 
stout, rugose; femora clavate, each with a small triangular tooth, the anterior pair at least with a minute
