tarsal claws. The seriate punctures of the elytra are smaller in the two Guatemalan 
examples than in those from Panama.

Conotrachelus signatus, Kirsch, Berl. ent. Zeitschr. 1875, p. 180°. 
Conotrachelus ferrugatus, Chevr. in litt.’. 
Subovate, rather dull, piceous (in one specimen obscure ferruginous, with darker markings), the tarsi reddish ; 
the vestiture fine, rather close, and of a uniform dark reddish-brown colour above, the prothorax with a 
narrow sinuous line on each side of the disc, divided into two at the base, the elytra with a transverse 
interrupted patch at the shoulders and a rounded spot on the subapical callus, and the prosternum with 
a transverse space before the anterior cox, densely clothed with whitish scales ; the femora with a ring 
of whitish scales a little beyond the middle. Head densely, rugosely punctate, the eyes large and rather 
narrowly separated ; rostrum very stout, strongly curved, considerably longer than the head and prothorax, 
5-carinate in its basal two-thirds and thickly punctate thence to the tip, the antenne inserted at one-third 
from the apex, joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, rounded at the 
sides anteriorly, subparallel behind, feebly constricted in front, strongly bisinuate at the base; densely, 
rugosely punctate. Elytra subtriangular, strongly sinuate at the base, the sides rounded posteriorly ; 
seriate-punctate, the interstices broad and rugulose, 3, 5, 7, and 9 costate, the ridge on 3 and 5 very 
prominent, broadly and abruptly twice interrupted, that on 7 interrupted below the rather prominent 
humeri. Mesosternum flattened between the cox, and obsoletely bituberculate in front, Ventral 
segments shining, very sparsely, minutely punctate. Femora clavate, each with an acute, triangular 
tooth and a small well-detined tooth exterior to it. Tarsal claws with a short tooth, 
Length 45-53, breadth 23-3 millim, 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).—CoLomBia, Bogota (Mus. 
Brit.); Peru!. 
Eight specimens, differing from a co-type from Peru in their larger size and shorter 
femoral teeth. In this insect the vestiture of the upper surface is fine and of a uniform 
dark reddish-brown colour, and the dense patches of whitish scales are very sharply 
defined. ‘The finer vestiture, the larger outer femoral tooth, the smaller seriate punctures 
on the elytra, &c., separate C. stgnatus from C. guadrinotatus and C. quadripustulatus. 
This species seems to be a near ally of C. repens, Boh., from Brazil, but the vestiture 
is closer and differently coloured ; the whitish markings, however, are very similar, 
36. Conotrachelus cribratus, sp. n. 
Oblong-ovate, shining, piceous or rufo-piceous; the vestiture very sparse, whitish, subfasciculate on the elytra, 
and condensed into a minute spot on each of the hind angles of the prothorax, the femora with a narrow 
whitish ring beyond the middle, the anterior pair with a faint line of fulvous scales at the base above. 
Head closely punctate, transversely depressed and feebly foveate in front; rostrum ( ¢) stout, curved, 
considerably longer than the head and prothorax, 5-carinate, sparsely punctate at the tip, (Q ) a little 
longer and smoother, the antenne inserted at from one-third (2) to one-fourth (¢) from the apex, 
joints 1 and 2 of the funiculus elongate, subequal. Prothorax nearly as long as broad, rounded at the 
sides anteriorly, narrowed and feebly constricted in front, strongly bisiuuate at the base ; very coarsely, 
closely punctate, the punctures here and there confluent, aud teebly carinate down the middle towards 
the apex. Elytra rather long, narrowing from a little below the base, deeply sinuate in front, the humeri 
prominent; coarsely seriate-punctate, the interstices narrow, 3, 5, 7, and 9 costate, the ridge on 3 and 5 
twice, and that on 7 once, somewhat abruptly interrupted. Mesosternum flattened between the ccxw,
