566 RHYNCHOPHORA. 
seriate-punctate, the interstices rugulose, faintly granulate at the base, 3, 5, 7, and 9 costate, the ridge 
on 3 twice, that on 5 thrice, and that on 7 once, abruptly interrupted. Mesosternum flattened between 
the coxew. Ventral segments sparsely, somewhat coarsely punctate. Femora clavate, rugose, unidentate, 
the tooth not very prominent. Tarsal claws with a long tooth. 
Length 5-6, breadth 24-3 millim. (d @.) 
Hab. Panama, Volcan de Chiriqui 5000 feet (Champion). 
The description of this insect is taken from three specimens; a fourth has the 
sculpture of the prothorax and elytra coarser, and indications of a second very minute 
tooth on the femora at some distance from the other. The shortly setose elytra, the 
feebly bisinuate base of the prothorax, the moderately coarse sculpture of the latter, 
and the not very prominent femoral tooth, distinguish C. fasciculatus from its 
immediate allies. 
44, Conotrachelus picticollis, sp.n. (Tab. XIX. figg. 4, 4a, 3; 46, anterior 
femur.) 
Oblong-ovate, dull, nigro-piceous or black; the vestiture very sparse, ochreous above, whitish beneath and on 
the legs, that on the elytra here and there condensed and fasciculate, and that on the prothorax condensed 
into two small spots on the disc a little behind the middle and another at each hind angle, the anterior 
femora with a narrow line of ochreous scales at the base above. Head closely, rugosely punctate ; 
rostrum stout, curved, a little longer than the head and prothorax, rugulose and 5-carinate in both sexes, 
the apical portion closely punctate in the $ and smoother in the 9, the antenne in the ¢ inserted at 
one-fourth, and in the 2 at one-third, from the tip, joints 1 and 2 of the funiculus equal in length. 
Prothorax broader than long, rounded at the sides anteriorly, narrowed and feebly constricted in front, 
bisinuate at the base; densely, rugosely punctate, carinate down the middle anteriorly. Elytra con- 
stricted at the sides below the humeri, narrowing from about the basal third; seriate-punctate, the 
interstices rugulose and obsoletely granulate, 3, 5, 7, and 9 costate, the ridge on 3, 5, and 7 abruptly 
twice interrupted. Mesosternum flat between the coxe, protuberant and bituberculate in front. 
Ventral segments shining, sparsely, finely punctate. Femora clavate, rugose, each armed with a stout 
triangular tooth, and with a small tooth placed nearly midway between it and the apex. Tarsal claws 
with a short tooth. 
Length 63-775, breadth 33-3% millim. (3 9.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Three specimens. The protuberant, bituberculate mesosternum, the dense, mode- 
rately coarse sculpture of the prothorax, the disc of the latter having two conspicuous 
ochreous spots, the fasciculate arrangement of the elytral vestiture, the dull upper 
surface, and the bidentate femora, are the chief characters of this species. It is very 
like C. bedentatus, Boh., from Colombia (the type of which I have seen), but has the 
prothorax much more finely punctured, and wanting the four tubercles on the disc. 
45. Conotrachelus lineatipes, sp. n. 
Subovate, slightly shining, nigro-piceous or black, the tarsi and antenne partly reddish; the vestiture very 
sparse, ochreous above and whitish beneath and on the legs, that on the elytra subfasciculate, and that 
on the prothorax condensed into two small spots on the disc before the middle and another at each hind 
angle, the femora sometimes with a faint whitish ring, the anterior pair with a rather broad line of 
fulvous scales along their basal half above. Head densely, rugosely punctate ; rostrum curved, stout, 
considerably longer than the head and prothorax, 5-carinate, sparsely punctate at the tip, the antenne
