CONOTRACHELUS. 3690 
funiculus subequal in length. Prothorax broader than long, narrowed and constricted in front, parallel 
behind, the sides slightly crenulate, the base feebly bisinuate; closely, irregularly foveolate, the inter- 
spaces rugulose, and here and there smooth and nodose. Elytra comparatively short, narrowing from 
about the basal third; coarsely seriate-punctate, the interstices slightly rugulose, 3, 5, 7, and 9 feebly 
costate, the ridge on 83 and 5 depressed or interrupted below the base. Intermediate coxw rather 
narrowly separated, the mesosternum flattened between them, and somewhat protuberant or bituberculate 
in front. Ventral segments sparsely, finely punctate. Legs stout, setose; femora feebly unidentate, the 
tooth distant from the apex and very small on the anterior pair; tarsal claws with a long tooth. 
Length 37-4}, breadth 2-2; millim. (<¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Three specimens. ‘This insect is very like C. foveicollis, but the femora are feebly 
unidentate, the elytral costz are not so prominent and less interrupted, the tibie are 
infuscate, and the vestiture of the upper surface is greyish, except at the base of the 
elytra, where it is rather broadly fulvous. There is an allied form from Colombia in 
the British Museum with the elytral costee uninterrupted and very prominent. 
42. Conotrachelus unidentatus, sp. n. 
Subovate, somewhat shining, nigro-piceous or black, the antenne and the tips of the tarsi ferruginous; the 
vestiture very sparse, fine, and whitish, slightly fasciculate on the elytra, becoming longer, yellowish, and 
very scattered on the prothorax, the anterior femora with a narrow line of fulvous scales at the base above. 
Head closely, rugosely punctate ; rostrum exceedingly stout, curved, tapering outwardly, as long as the 
head and prothorax, seriate-punctate and 5-carinate, sparsely punctured at the apex, the antenne stout, 
inserted at about one-fourth from the tip, joint 2 of the funiculus much shorter than 1. Prothorax 
broader than long, rounded at the sides anteriorly, parallel behind, narrowed and feebly constricted in 
front, strongly bisinuate at the base; very coarsely, rugosely punctured, carinate down the middle 
anteriorly, the rugs becoming longitudinal on the disc towards the apex. Elytra oblong-subcordate, 
slightly constricted at the sides below the humeri ; coarsely seriate-punctate, the punctures subquadrate, 
the interstices narrow, closely rugulose, 3, 5, 7, and 9 moderately costate, the ridge on 3 twice, and that 
on 5 once, abruptly interrupted, Mesosternum flattened between the cox, rather prominent in front. 
Ventral segments shining, somewhat coarsely, sparsely punctate. Legs stout; femora clavate, unidentate ; 
anterior tibie strongly sinuate within ; tarsal claws with a short tooth, 
Length 44-53, breadth 23-3 millim. (¢.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Four specimens. The whitish vestiture of the elytra, the very coarse sculpture of 
the prothorax, the stout legs, the sinuous inner edge of the anterior tibie, and the 
unidentate femora, distinguish C. wnidentatus from most of its allies. 
43. Conotrachelus fasciculatus, sp. n. 
Oblong-ovate, subopaque, nigro- or rufo-piceous; the vestiture very sparse, ochreous above and condensed 
into a small patch at each of the hind angles of the prothorax and numerous others on the elytra, that 
of the under surface and legs whitish, the elytra also with short, scattered, ochreous set. Head densely 
punctate, foveate between the eyes; rostrum ( ¢') stout, curved, about as long as the head and prothorax, 
5-carinate, thickly punctate at the tip, (2) a little longer and much smoother, the antenne in the ¢ 
inserted at one-fourth, and in the Q at one-third, from the apex, joints 1 and 2 of the funiculus equal 
in length. Prothorax broader than long, abruptly narrowed in front, the sides somewhat sinuous and 
subcrenulate, the base feebly bisinuate; densely, rather finely punctate, carinate down the middle 
anteriorly. Elytra narrowing from a little below the base, the humeri obliquely truncated in front;
