436 RHYNCHOPHORA. 
A common insect in Chiriqui, and recognizable by its arched body, the dense 
vestiture of the front of the head and of the elytra, the latter with a dark patch at the 
middle of the suture, the almost bare, very coarsely punctured prothorax, &c. Our 
specimens agree with others from Brazil in the British Museum. 
172. Conotrachelus glabricollis, sp. n. 
Subovate, moderately shining, black, the elytra rufo-piceous, with a common transverse median fascia and a 
patch at the apex black, the antenn, rostrum, and legs partly ferruginous ; the vestiture fine, close on 
the elytra and legs, very scattered on the other parts of the body, brownish, becoming paler and more 
condensed along the base of the elytra, the latter also set with very short, fine, scattered, decumbent, 
pallid sete. Head densely, rugulosely punctate; rostrum (¢ ) rather slender, considerably longer than 
the head and prothorax, abruptly curved from a little beyond the middle, rugulosely punctate and feebly 
tricarinate, and with the apical portion sparsely punctate, (2) longer, smoother, and more curved towards 
the apex, the antenne in the Q inserted at the middle, andin the d a little nearer the tip, joints 1 and 2 
of the funiculus equal in length. Prothorax broader than long, subconical, slightly constricted in front, 
moderately bisinuate at the base; densely, rather finely punctate, and incompletely carinate. LElytra 
comparatively long, nearly twice as wide as the prothorax, subtriangular, the humeri rounded; seriate- 
punctate, the interstices closely rugulose, 3, 5, 7, and 9 narrowly costate, the ridge on 3 depressed 
or interrupted below the base. Rostral canal deep, nearly or quite reaching the apex of the metasternum. 
Legs short ; femora acutely unidentate; tarsal claws with a long tooth. 
Length 4-43, breadth 2,2,-27 millim. (d 9.) 
Hab. Panama, Bugaba, Tolé (Champion). 
Two specimens. Very like C. sobrinus, but smaller and less convex, the prothorax 
not so coarsely punctured, the elytra more truncate at the base, the rostrum longer in 
the female and more curved, the rostral canal deep and reaching the apex of the 
metasternum. The last-mentioned character almost excludes C. glabricollis from 
Conotrachelus. 
173. Conotrachelus ciliatus, sp. n. (Tab. XXI. figg. 23, 23a; 236, hind 
leg, 3.) 
Oblong-ovate, moderately shining, nigro-piceous or black, the antenne and the tips of the tarsi obscure 
ferruginous ; the vestiture sparse, reddish-brown, slightly intermixed with white, becoming rather dense on 
the elytra, that on the legs bristly and mostly white, the elytra with a dense, transverse, white or ochreous 
patch on each shoulder, and also conspicuously setose, the prothorax with a small white spot at each 
hind angle, and sometimes two minute ones on the disc, the femora each with a whitish ring, the anterior 
pair with a fulvous line along their basal half above. Head rugosely punctate, depressed, carinate, and 
feebly binodose in front; rostrum curved, moderately stout, considerably longer than the head and 
prothorax, 5-carinate, sparsely punctured at the tip, the apical portion a little smoother in the 2, the 
antenne inserted at about one-fourth or one-fifth from the apex, joints 1 and 2 of the funiculus elongate, 
subequal in length. Prothorax broader than long, constricted and narrowed in front, feebly bisinuate 
at the base; coarsely, rugosely punctured, and finely carinate to near the base. Elytra convex, elongate- 
subtriangular, rounded at the sides posteriorly, the humeri rounded externally ; seriate-punctate, the 
interstices 3,5, 7, and 9 narrowly costate, the ridge on 3 and 5 slightly interrupted below the base. 
Meso- and metasternum deeply hollowed down the middle. Ventral segments sparsely, coarsely punctate. . 
Legs rather elongate ; femora unidentate ; intermediate and posterior tibie closely fulvo-ciliate on their 
inner edge from about the middle to the apex, and the anterior pair also ciliate at the tip, in the ¢ ; 
tarsal claws with the inner tooth nearly as long as the claw itself. 
Length 53-65, breadth 3-3} millim. (¢ 2.)
