572 RHYNCHOPHORA. 
55. Conotrachelus annulipes, sp. n. 
Subovate, shining, piceous, the antenne and tarsi ferruginous ; the vestiture very sparse, ochreous above and 
whitish beneath and on the legs, subfasciculate on the elytra, that on the prothorax condensed into a 
faint longitudinal line on each side of the disc, which is continued on to the base of the third elytral 
interstice, the humeri also with a transverse ochreous patch in front; the femora with a whitish ring 
beyond the middle, the anterior pair with a conspicuous line of fulvous scales along their basal half above. 
Head rugosely punctate, faintly carinate in one specimen, transversely grooved in front; rostrum 
exceedingly stout, arched, gibbous at the base, tapering at the tip, a little longer than the head and 
prothorax, rugulose and 5-carinate, the apex rather sparsely punctate, the antenne inserted at about 
one-third from the tip, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, 
narrowed and feebly constricted in front, strongly bisinuate at the base, the sides parallel behind; 
coarsely, rugosely punctate. Hlytra narrowing from a little below the base, constricted behind the 
humeri, which are rounded ; coarsely seriate-punctate, the interstices narrow, slightly rugulose, 3, 5, 7, 
and 9 sharply costate, the ridge on 3 and 5 twice, and that on 7 once, abruptly interrupted. Mesosternum 
flattened between the cox, obsoletely bituberculate in front. Ventral segments sparsely punctate. 
Legs rather slender ; femora clavate, sharply unidentate ; tarsal claws with a short tooth. 
Length 4-4}, breadth 23-23 millim. (¢?) 
Hab. Panama, Bugaba (Champion). 
Three specimens. A small species, recognizable by its shining surface and sparse 
vestiture, the exceedingly stout, arched, tapering rostrum, the two small ochreous 
patches at the base of each elytron, the inner one extending forwards along the disc 
of the prothorax, and the annulate, unidentate femora, the anterior pair with a con- 
spicuous line of fulvous scales. It is much smaller than C. /ineatipes, and has a very 
differently shaped rostrum. 
56. Conotrachelus duplicatus, sp. n. 
Subovate, slightly shining, piceous or rufo-piceous, more or less mottled with black, the antenne and the tips 
of the tarsi ferruginous ; the vestiture very sparse, ochreous, condensed into a narrow oblique line on each 
side of the disc of the prothorax and a faint spot within the humeri, becoming closer towards the sides 
and on the apical declivity of the elytra, the femora with a faint ochreous or whitish ring beyond the 
middle. Head rugosely punctate, somewhat depressed or flattened, and often feebly carinate, between 
the eyes; rostrum (¢ 2) exceedingly stout, arched, tapering a little towards the tip, scarcely as long 
as the head and prothorax, 5-carinate, the apical portion punctate and in the Q slightly smoother, the 
antenne inserted at about one-fourth from the apex, joint 2 of the funiculus shorter than 1. Prothorax 
transverse, narrowed and constricted in front, strongly bisinuate at the base, the sides a little rounded ; 
coarsely, rugosely punctate, carinate down the middle anteriorly. Elytra narrowing from near the base, 
constricted a little below the humeri, and strongly sinuate in front; coarsely seriate-punctate, the 
interstices rugulose, 3, 5, 7, and 9 costate, the ridge on 3 and 5 twice, and that on 7 once, abruptly 
interrupted. Mesosternum flattened between the coxe, bituberculate in front. Ventral segments 
shining, very sparsely, finely punctate, 5 depressed in the middle behind in the ¢. Legs stout; femora 
clavate, each with a stout triangular tooth and a minute tooth placed at some distance from it exteriorly ; 
tarsal claws with a long tooth. 
Length 42-53, breadth 22-24 millim. (¢ 9.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Found in abundance in Chiriqui. In this insect the rostrum is very stout, sharply 
o-carinate, and comparatively short in both sexes, the apex being merely a little 
smoother in the female. The vestiture of the elytra is very sparse on the anterior half 
of the disc, becoming closer towards the sides and apex, and on the prothorax it is
