CONOTRACHELUS., oe 
Prothorax broader than long, rounded at the sides anteriorly, constricted and narrowed in front, 
bisinuate at the base; coarsely, rugosely punctate, and carinate to near the base. Elytra subparallel to 
near their basal third, feebly constricted below the humeri, which are rounded externally ; seriate- 
punctate, the interstices 3, 5, 7, and 9 uninterruptedly costate. Mesosternum flattened between the 
coxe, slightly swollen on each side anteriorly. Ventral segments coarsely, very sparsely punctate, 
1 depressed in the middle at the apex in the ¢. Legs stout; femora feebly clavate, narrowly, acutely 
unidentate ; tarsal claws with a short tooth. 
Length 7%, breadth 4 millim. (¢ @.) 
Hab. Panama, Bugaba (Champion). 
One pair. Broader and more robust than C. fulvescens, the elytral coste uninter- 
rupted, the femoral tooth acute, narrow, and simple, the rostrum stouter and 5-carinate 
in both sexes. 
20. Conotrachelus longipennis, sp.n. (Tab. XVIII. figg. 17, 17a, 2.) 
Oblong, shining, obscure ferruginous, the rostrum, the disc of the prothorax, and various irregular patches on 
the elytra nigro-piceous or black ; the vestiture rather coarse, dense, brownish, intermixed with white, 
especially on the prothorax, becoming sparser on a small space on the disc of the latter behind, and more 
or less fasciculate on the elytra, the head with two sharply-defined white spots placed one above the 
other, the lower one transverse, the femora obsoletely biannulate with whitish. Head densely punctate ; 
rostrum moderately stout, curved, much longer than the head and prothorax, slightly dilated at the tip, 
rugulosely punctate and feebly unicarinate, smoother at the apex, sulcate laterally at the base, the 
antenne inserted a little behind the middle, joint 2 of the funiculus shorter than 1, 3-5 decreasing in 
length. Prothorax broader than long, subconical, slightly constricted towards the apex, deeply bisinuate 
at the base; rather closely punctate, with the interspaces minutely punctured, the disc gibbous and 
ecarinate at the middle. Elytra comparatively elongate, triangular, abruptly declivous at the sides, 
strongly sinuate at the base, with the humeri obliquely truncate in front; very coarsely seriate-punctate, 
the punctures deep and rounded, the interstices rugulose, 3, 5, 7, and 9 sharply costate throughout. 
Intermediate coxe widely separated, the mesosternum flattened between them. Ventral segments 
closely, finely punctate. Legs stout ; femora clavate, unidentate ; tarsal claws with a short tooth. 
Length 63, breadth 3} millim. (2.) 
Hab. Guatemaua, Duefias (Champion). 
One specimen. The subconical prothorax, with the middle of the disc swollen and 
carinate, the elongate, triangular, mottled elytra, with sharply carinate alternate inter- 
stices, the two white spots on the head, &c., distinguish C. longipennis. ‘The antenne 
are inserted nearer the base than usual in the females of the nearest allied forms. 
21. Conotrachelus rugulosus, sp.n. (Tab. XVIII. figg. 18,184, ¢.) 
Subovate, shining, nigro-piceous, the elytra rufo-piceous, the legs in part, and the antenna, ferruginous; the 
vestiture sparse, fine, ochreous, denser on the front of the head and slightly fasciculate on the elytra, the 
prothorax with a sharply-defined, condensed, oblique, ochreous line on each side of the disc, these two lines 
nearly meeting in front and continued posteriorly on to the base of the sixth elytral interstice, the femora 
faintly biannulate. Head densely punctate; rostrum moderately stout, strongly curved, slightly depressed 
at the base above, nearly twice as long as the prothorax, 5-carinate, the apical third thickly punctate, 
the antenne inserted at one-third from the tip, joint 2 of the funiculus a little shorter than 1. Prothorax 
strongly transverse, rounded at the sides anteriorly, narrowed and slightly compressed in front, moderately 
sinuate at the base; densely, rugosely punctate. Elytra rather short, less than twice the width of the 
prothorax, arcuately narrowing from a little below the base, the humeri rounded; punctate-striate, the
