CONOTRACHELUS. 437 
Hab, Panama, Boquete, Volcan de Chiriqui (Champion). 
Six specimens. Larger than C. glabricollis, the prothorax rugosely punctate, the 
upper surface more setose, the legs longer, the intermediate and posterior tibie closely 
ciliate within in the male. 
174. Conotrachelus sublineatus, sp. n. 
Oblong-ovate, shining, piceous, much mottled with ferruginous, the antenne, rostrum, tibie, and tarsi almost 
wholly of that colour ; the vestiture ochreous, intermixed with whitish, rather coarse, very sparse, closer 
on the elytra, that on the alternate interstices of the latter almost entirely whitish and subfasciculate, 
and that on the others uniformly ochreous. Head densely punctate, feebly foveate between the eyes ; 
rostrum stout, curved, a little longer than the head and prothorax, rugulosely punctate and unicarinate, 
sparsely punctate at the tip, the antenne inserted near the apex, joint 2 of the funiculus shorter than 1. 
Prothorax transverse, narrowing almost from the base, slightly constricted in front, the base feebly 
bisinuate ; deeply, densely, rather coarsely punctate, the narrow raised interspaces tending to form 
longitudinal rugee at the apex. LElytra one-half wider than the prothorax, parallel at the base, the 
humeri obliquely truncated ; seriate-punctate, the interstices rugulose, 3, 5,7, and 9 uninterruptedly 
costate. Rostral canal broad and deep, about reaching the middle of the metasternum. Ventral 
segments sparsely punctate. Femora clavate, unidentate. Tarsal claws with a short tooth. 
Length 33, breadth 14 millim. (¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One immature specimen. In this insect the elytral vestiture is uniformly arranged 
and ochreous in colour on the interstices 2, 4, 6, 8, and whitish and subfasciculate on 
the others. 
175. Conotrachelus tabogensis, sp. n. 
Oblong-ovate, moderately shining, pitchy-black, the elytra rufo-piceous, the antenna, the rostrum, and the 
legs in part ferruginous; the vestiture rather close and subfasciculate on the elytra, and somewhat 
condensed at the base of the third interstice, very sparse on the rest of the body, moderately close on the 
legs, ochreous, slightly intermixed with whitish, the femora obsoletely annulate. Head densely, 
rugulosely punctate ; rostrum curved, rather slender, a little longer than the head and prothorax, 
rugulose and finely unicarinate at the base, very sparsely punctate from the middle onwards, the antenne 
inserted at about two-fifths from the apex, joint 2 of the funiculus much shorter than 1. Prothorax 
broader than long, narrowed and slightly constricted in front, feebly bisinuate at the base, the sides 
parallel behind ; densely, rather finely punctate, obsoletely carinate anteriorly. Elytra one-half wider 
than the prothorax, parallel at the base, the humeri rounded; seriate-punctate, the interstices finely 
rugulose, 3, 5, 7, and 9 moderately costate, the ridge on both 3 and 5 becoming indistinct anteriorly 
and interrupted below the base. Rostral canal broad and deep, extending to the middle of the 
metasternum. Ventral segments sparsely punctate. Femora clavate, unidentate. Tarsal claws with a 
very short tooth. 
Length 33, breadth 1;% millim. ( 9.) 
Hab. Panama, Taboga I. (Champion). 
One specimen. JDistinguishable from the other Central-American species with a 
similarly-formed rostral canal, the preceding excepted, by the relatively narrow elytra 
and oblong-ovate shape. Compared with C. sudlineatus, the rostrum is much more 
slender, the prothorax is less coarsely punctate, and the vestiture of the elytra is 
longer and more uniform in colour and distribution.
