CONOTRACHELUS. 389 
white, the dorsal tubercles of the prothorax setose. Head densely punctate, slightly depressed between 
the eyes ; rostrum very stout, longer than the head and prothorax, curved, rugulose, sulcate at the sides 
and feebly 5-carinate, gibbous at the base, sparsely punctate and bare at the tip, the antenne in the ¢ 
inserted at one-third from the apex and in the @ at a little nearer the middle, joint 2 of the funiculus fuly 
as long as 1. Prothorax transversely subquadrate, abruptly narrowed and constricted in front, the 
margins distinctly dentate or angulate before and behind the middle, the base feebly bisinuate ; the 
surface uneven, sparsely, irregularly punctate, almost smooth in the middle behind, carinate to near 
the base and also with one or two short carine towards the sides, the disc with two large compressed 
tubercles at the middle, two small ones at the apex, and two others towards the base. Elytra 
subtriangular, a little rounded at the sides, the latter with a small conical prominence below the base 
beneath, the humeri dentiform, obliquely truncated in front; seriate-punctate, the interstices 3, 5, 7, 
and 9 very sharply costate, the ridge on 3 and 5 twice, and that on 7 once, abruptly interrupted, the 
elongate median elevation on 3 large and lamelliform. Mesosternum bituberculate in front. Ventral 
segments shining, very sparsely, finely punctate. Legs rather elongate; femora strongly clavate, 
bidentate—the inner tooth large, triangular, emarginate externally, the outer one small, but prominent; 
tarsi slender, the claws with a very short tooth. 
Length 31-4}, breadth 2-2} millim. (d¢ 9.) 
Hab. Panama, Volcan de Chiriqui 2000-4000 feet (Champion). 
Ten examples. This insect approaches C. tuberculatus, but differs from it in the 
armature of the femora, the form of the mesosternum, &c.; the prothoracic tubercles 
are clothed with long sete (appearing pointed), the rest of the surface being 
without bristles; the rostrum is longer and not so stout, &c. C. clivosus, Faust, 
from Venezuela, is very similar to C. spinifer, but has smaller tubercles on the 
prothorax, &c. 
86. Conotrachelus reticulatus, sp.n. (Tab. XIX. figg. 28, 28a, 3.) 
Subovate, opaque, nigro-piceous, the antenns and tarsi obscure ferruginous; the vestiture of the head and 
rostrum dense, ochreous or whitish above, brown at the sides, that on the prothorax and elytra short 
and close, brown, the prothorax with a network of narrow whitish lines, which become broader and 
ochreous in colour on the two prominences at the apex, and are continued along the shoulders of the 
elytra and down the base of the third interstice, the elytra with a dense white patch covering the apical 
declivity (a space along the suture posteriorly excepted), the seriate punctures each with a small white 
scale; the clothing of the under surface very sparse, that of the legs close, brownish and white inter- 
mixed, the femora narrowly biannulate with whitish; the entire surface also set with scattered, 
suberect, blunt, light and dark sete, which are clustered into crests on the ridges in front of the 
prothorax. Head densely, rugulosely punctate, transversely depressed in front, foveate between 
the eyes ; rostrum exceedingly stout, curved, not longer than the head and prothorax, sculptured like the 
head, the extreme tip bare, shining, and sparsely punctate, the antenne inserted at one-fourth from 
the apex, joints 1 and 2 of the funiculus subequal. Prothorax transversely subquadrate, the sides 
compressed at the middle and abruptly constricted at the apex, the base deeply bisinuate ; sparsely, 
rather coarsely punctate, feebly binodose at the middle of the disc and with two oblong prominences in 
the centre in front. Elytra broad, flattened on the disc, subcordate, compressed for some distance below 
the somewhat obliquely truncated humeri, the sides angularly dilated below the base beneath ; seriate- 
punctate, the interstices broad, finely rugulose, 3, 5, 7, and 9 interruptedly costate, the median elevation 
on 3 very large, lamelliform, and somewhat pointed behind. Mesosternum bluntly protuberant in front. 
Ventral segments opaque, with scattered coarse punctures. Femora clavate, unidentate. ‘Tarsal claws 
with a long tooth. 
Length 54, breadth 3 millim. (<d.)

(Champion).
