side of the disc of the prothorax, and conspicuously fasciculate on the elytra; the 
intermediate coxee more approximate; the femora less distinctly bidentate; the 
prothorax shorter, &c. 
108. Conotrachelus nemorivagus, sp. n. 
Subovate, shining, black, the elytra and legs mottled with obscure ferruginous, the antenne and the tips of 
the tarsi ferruginous ; the vestiture ochreous, very sparse, a little closer and fasciculate on the elytra, the 
latter with an ochreous streak along the humeri in front, the femora faintly biannulate, the anterior pair 
with a fulvous line along their basal half above. Head closely, rugulosely punctate, somewhat depressed 
in front, feebly foveate between the narrowly separated eyes; rostrum very stout, arcuate, not longer 
than the head and prothorax, rugulose and 5-carinate, the apical portion sparsely punctured, the antenne 
inserted a little before the tip, joint 2 of the funiculus slightly shorter than 1. Prothorax transverse, 
rather convex, narrowed and feebly constricted in front, deeply bisinuate at the base; very coarsely, 
rugosely punctate, and sharply carinate to near the base. LElytra subtriangular, short, transversely 
convex, rather more than one-half wider than the prothorax, strongly sinuate at the base, the humeri 
rounded ; coarsely seriate-punctate, the punctures subquadrate, the interstices narrow, 3, 5, 7, and 9 very 
sharply costate, the ridge on 3 abruptly interrupted below the base only. Mesosternum simply flattened 
between the cox. Ventral segments sparsely, finely punctate. Femora clavate, sharply unidentate. 
Tarsal claws with a short tooth. 
Length 34-34, breadth 1,,-25 millim. (¢ 2.) 
Hab. Panama, Bugaba (Champion). 
Three specimens. The short, transversely convex, subtriangular elytra, with the 
acute ridge on the third interstice interrupted below the base only, and the very coarsely 
punctured, carinate prothorax, chiefly distinguish this small species. It somewhat 
approaches C. miatus. 
109. Conotrachelus divisus, sp.n. (Tab. XX. figg. 12, 12a.) 
Subovate, moderately shining, nigro-piceous, the elytra rufo-piceous, the antenne and the tips of the tarsi 
obscure ferruginous; the vestiture sparse, ochreous, slightly intermixed with white, the elytra with a 
very large, dense, whitish patch occupying about the apical two-fifths ; the clothing of the under surface 
very scattered and whitish, that of the legs closer, ochreous and white intermixed, the femora with 
indications of a whitish ring. Head densely punctate; rostrum stout, curved, not longer than the head 
and prothorax, rugulosely punctate and 5-carinate, bare and sparsely punctate at the tip, the antenne 
inserted at about one-third from the apex, joint 2 of the funiculus shorter than 1. Prothorax transverse, 
abruptly narrowed and constricted in front and slightly narrowed behind, the base deeply bisinuate ; 
densely, rather finely punctate, not carinate. Elytra narrowing from about the basal third, obliquely 
constricted beneath the rounded humeri; very coarsely seriate-punctate, the interstices narrow, rugulose, 
3, 5, 7, and 9 sharply costate, the ridge on 3 interrupted beyond the middle. Mesosternum slightly 
depressed between the coxe, bituberculate in front. Ventral segments very sparsely, finely punctate. 
Femora clavate, unidentate. Tarsal claws with a moderately long tooth. 
Length 6, breadth 375 millim. (¢ ?) 
Hab. GuateMaa, Cerro Zunil (Champion). 
One specimen. This insect has the general facies of C. alboplagiatus and C. allo- 
signatus, but the elytra lack the large lamelliform prominence at the middle of the 
third interstice, the ridge on the latter is only once interrupted, and the seriate 
punctures are larger; the prosternal tubercles, too, are absent.
