392 RHYNCHOPHORA. 
sparsely, finely punctate, 1 sulcate down the middle behind in the ¢. Femora clavate, bidentate, the 
outer tooth very small, but distinct. Tarsal claws with a rather long tooth. 
Length 42-5, breadth 23-25 milliim. (¢ @.) 
Hab. Mexico, Toxpam (Sallé), Atoyac in Vera Cruz (H. H. Smith). 
Four specimens. A species resembling C. flavangulus, but with the dorsal coste of 
the elytra prominent and broadly and abruptly twice interrupted. the femora more 
distinctly bidentate and distinctly annulate, the elytra with a dense white fascia towards 
the apex *. Compared with C. unifasciatus the elytra are much less coarsely seriate- 
punctate, and have the elevations on the disc less prominent, the ridge on the seventh 
interstice uninterrupted. 
91. Conotrachelus vittaticollis, sp.n. (Tab. XX. figg. 3, 3a, 2.) 
Subovate, shining, piceous above, darker beneath, the antenne, tibia, and tarsi more or less ferruginous ; the 
vestiture rather close, ochreous, becoming whiter at the base of the elytra, on the scutellum, and on 
the prothorax, and condensed into five faint longitudinal vitte on the latter, the clothing of the under 
surface sparse and whitish, the femora biannulate. Head densely punctate, shallowly foveate between 
the eyes; rostrum very stout, curved, a little longer than the head and prothorax, rugulose and tricarinate, 
the apex thickly punctate in the ¢, smoother in the 9, the antenna inserted towards the tip, joint 2 
of the funiculus slightly shorter than 1. Prothorax a little broader than long, rounded at the sides 
anteriorly, narrowed and compressed in front, moderately bisinuate at the base ; densely, finely punctate, 
the disc with four minute smooth tubercles. Elytra compressed and laterally dilated below the rounded 
humeri, and narrowing thence to the apex ; rather finely seriate-punctate, the interstices closely rugulose, 
3, 5, 7, and 9 very sharply undulato-costate, the ridge on 3 twice, and that on 7 once, interrupted. 
Mesosternum flattened between the coxe. Ventral segments sparsely punctate. Femora unidentate. 
Tarsal claws with a short tooth. 
Length 32-34, breadth 2 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui 2500-4000 feet (Champion). 
One pair. A small species resembling C. dentiferus, Fahr., in general facies, the 
prothorax 5-vittate, with four shining minute prominences on the disc, the dorsal 
cost of the elytra less interrupted (the second from the suture entire), the humeri 
not so prominent, &c. 
92. Conotrachelus megalops, sp.n. (Tab. XX. figg. 4, 4a, 2.) 
Subovate, shining, black, the elytra and legs variegated with ferruginous, the antenne and tarsi entirely of 
that colour; the vestiture sparse, fine, ochreous, intermixed with white on the legs and under surface, 
that on the elytra condensed into small scattered patches, the humeri with a dense whitish patch in 
front, the femora biannulate. Head densely, rugulosely punctate, the eyes very large and narrowly 
separated ; rostrum very stout, about as long as the head and prothorax, curved, rugulose and 5-carinate at 
the base, the apical half thickly punctate, the antenne inserted at about the middle, joint 2 of the funiculus 
slightly shorter than 1. Prothorax transverse, subquadrate, abruptly narrowed and strongly constricted 
in front, deeply bisinuate at the base; closely, rather coarsely punctate, and with two prominent tubercles 
at the apex and two others on the disc just behind the apical constriction, the longitudinal intervening 
space feebly carinate. LElytra triangular, nearly twice as wide as the prothorax, compressed beneath the 
obliquely truncated humeri, sinuate at the base; coarsely seriate-punctate, the punctures placed in 
shallow strie, the interstices narrow, rugulose, 3, 5, 7, and 9 very sharply costate, 8 and 10 also costate 
* It would be equally well placed in sect. a’ in the Table.
