304 RHYNCHOPHORA. 
interstices densely rugulose, 3, 5, 7, and 9 narrowly, uninterruptedly costate, the ridge on 8 and 5 
becoming obsolete towards the base, that on 3 sinuate beyond the middle, 8 also subcostate. Mesosternum 
simply flattened between the coxe. Ventral segments sparsely, finely punctate. Femora clavate, 
finely unidentate. Tarsal claws with a moderately long tooth. 
Length 32, breadth 2 millim. (<¢.) 
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 
One specimen. A small species with densely rugulose elytral interstices, the 
alternate ones very narrowly costate, the prothorax with an oblique dense ochreous 
line on each side of the disc, the rostrum (¢ ) long, curved, and carinate. It super- 
ficially resembles C. mexicanus. 
22. Conotrachelus rugiventris, sp. n. (Tab. XVIII. fig. 19, head and 
rostrum,  .) 
Oblong-ovate, rather dull, black or piceous, the elytra sometimes obscure ferruginous mottled with black, the 
rostrum and legs in part, and the antenneg, reddish; the vestiture brownish, dense on the head, rather 
close and fasciculate on the elytra, sparse on the prothorax and under surface, the elytra sometimes 
slightly mottled with whitish, and with a small spot at the base of the third interstice and another on 
each shoulder, and occasionally a transverse subapical fascia also, whitish or fulvous, the femora faintly 
annulate ; the upper surface also set with numerous semierect, short, fine, pallid sete, the legs setulose. 
Head densely punctate, depressed between the eyes above; rostrum (¢ ) stout, tapering a little towards 
the tip, curved, about as long as the head and prothorax, rugosely punctate and 5-carinate, the apex 
thickly punctate, (Q) slender, more curved, and much longer, smooth along the middle, and striate at 
the sides to the tip, the antenne in the ¢ inserted at about one-third from the apex and in the 9 
slightly beyond the middle, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, 
rather convex, rounded at the sides anteriorly, constricted and narrowed in front, bisinuate at the base ; 
coarsely, rugosely punctate, and carinate to near the base. Elytra about one-half wider than the 
prothorax, narrowing from a little below the rounded humeri, sinuate in front; seriate-punctate, the 
interstices densely rugulose, 3, 5, 7, and 9 uninterruptedly costate. Ventral segments coarsely, densely 
punctate. Mesosternum flattened between the cox, binodose and somewhat protuberant in front. 
Legs rugose ; femora unidentate; tarsal claws with a short tooth, 
Length 43—6, breadth 2,;-3 millim. (¢ 2.) 
Hab. Mexico, Monclova in Coahuila (Dr. Palmer), Pinos Altos in Chihuahua 
(Buchan-Hepburn), Acapulco, Ventanas, Chilpancingo (Hége), Yolos, Capulalpam, 
Juquila, Parada (Saldé) ; Guaremana, San Gerdnimo (Champion). 
Ten specimens. The long, slender, strongly curved rostrum of the female separates 
this species from most of the allied Central and North-American Conotracheli. with 
uninterrupted elytral costa, coarsely punctured abdomen, and setose upper surface. 
23. Conotrachelus longirostris, sp. n. (Tab. XVIII. fige. 20, 20 a, 9 ) 
Oblong-ovate, rather broad, moderately shining, rufo-piceous above, piceous beneath, the rostrum ferruginous, 
with the apical fourth black, the legs in part and the antenne ferruginous ; the vestiture rather coarse, 
mostly ochreous or ferruginous above, close on the head and the base of the rostrum and rather scattered 
on the elytra, very sparse on the middle of the prothorax, that towards the sides of the latter white, 
becoming ferruginous on the flanks and towards the apex, the elytra with a broad, irregular, transverse, 
dense, white subapical fascia and a small transverse white patch on the humeri in front; the squamosity 
of the legs close and in great part ferruginous, becoming white on their inner face, that on the underside
