CONOTRACHELUS. 357 
punctate, foveate between the eyes ; rostrum nearly twice as long as the head and prothorax, curved, 
comparatively slender, closely, rugulosely punctate throughout, and also unicarinate, the antenne inserted 
at the middle, joints 1 and 2 of the funiculus subequal in length. Prothorax strongly transverse, 
abruptly narrowed in front, feebly bisinuate at the base ; densely, rugulosely punctate, binodose on the 
disc before the middle, and with two small tubercles at the apex and two others towards the base, and 
shallowly grooved down the centre anteriorly. Elytra short, constricted and angularly dilated below the 
obliquely truncated humeri; coarsely seriate-punctate, the interstices rugulose and uneven, 3, 5, 7, and 
9 strongly costate, the ridge on 3, 5, and 7 twice or thrice abruptly interrupted, the elevations on 3 very 
prominent, the others becoming tuberculiform or subconical towards the apex. Mesosternum flattened 
between the coxe, vertical and slightly hollowed in the middle in front. Ventral segments sparsely, 
finely punctate. Femora clavate, unidentate. Tarsal claws rectangularly dilated in their basal half. 
Length 33-4, breadth 2-2,1, millim. ( 9.) 
Hab. Guatemaua, Capetillo (Champion). 
Two females. Very like Anthonomus flavirostris in general facies, and differing 
from the nearest allied Conotracheli in the elongate rostrum (in the 2), and the 
cruciform white patch on the prothorax, which, however, is indistinct in one of the 
examples received.

ca) 
Subovate, rather shining, piceous or rufo-piceous, the antenne, the tip of the rostrum, and the tarsi more or 
less ferruginous ; the vestiture rather coarse, and moderately close, ochreous, intermixed or mottled with 
white, the prothorax with a small white spot at each hind angle, and sometimes a faint sinuous line on 
each side of the disc, and the elytra with a white patch on the humeri in front, the clothing of the 
under surface very sparse and white, the femora annulate with whitish, the anterior pair with a fulvous 
line along their basal half above. Head densely punctate, somewhat depressed between the eyes; rostrum 
of the ¢ curved, a little longer than the head and prothorax, stout and 5-carinate, becoming abruptly 
narrower and smoother towards the apex, the smooth apical portion in the 9 more elongate and 
comparatively slender, the antenne inserted at about one-third from the tip in the ¢, and considerably 
nearer the middle in the 2, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, 
narrowed and constricted in front, and subparallel behind, the base strongly bisinuate; densely, rugosely 
punctate, not carinate. Elytra rather short, widest a little below the base, sinuate in front, the humeri 
rounded ; coarsely seriate-punctate, the punctures subquadrate, the interstices feebly rugulose, 3, 5, 7, 
and 9 sharply, narrowly, uninterruptedly costate throughout. Mesosternum flattened between the coxe, 
slightly protuberant in front. Ventral segments shining, very sparsely, minutely punctate, 1 with a 
transverse line of coarser impressions. Femora clavate, each with an acute triangular tooth, the anterior 
pair with a minute prominence exterior to it. Posterior tibie slightly hollowed at the apex within, 
and strongly unguiculate, in the $. Tarsal claws with a long tooth. 
Length 33-44, breadth 175-2} millim. (¢ Q.) 
Hab. Panama, Bugaba, Volcan de Chiriqui, Caldera, David, Tolé (Champion). 
A common insect in the savana-region of Chiriqui. It is easily distinguishable by 
its abruptly narrowed rostrum, this being especially noticeable in the female. In this 
respect C. subulatus approaches the Anthonomid-genus Listrorrhynchus. C. brevicollis 
is an allied form.

Subovate, rather broad, shining, black, slightly mottled with ferruginous, the rostrum rufous, becoming darker 
at. the base, the antenne and tarsi obscure ferruginous; the vestiture rather coarse, close, ochreous
