CONOTRACHELUS. 431 
162. Conotrachelus curtus, sp. n. 
Short-ovate, shining, piceous or rufo-piceous, the rostrum, antenne, and tarsi ferruginous; thickly clothed 
with rather coarse, oval, fulvous or ochreous scales, with a few whitish ones intermixed, the elytra also 
with scattered, short, semierect, whitish and fuscous sete, the legs with whitish sets, the femora faintly 
annulate, the anterior pair with a fulvous line at the base above. Head densely punctate; rostrum 
moderately stout, considerably longer than the head and prothorax, curved, rugulosely punctate and feebly 
5-carinate, sparsely punctate at the tip, the antenne inserted a little nearer the apex in the ¢ than in 
the 2, joint 2 of the funiculus shorter than 1. Prothorax strongly transverse, narrowed and con- 
stricted in front, the sides parallel behind, the base deeply bisinuate ; densely, finely punctate, sharply 
carinate down the middle towards the base. Elytra rather short, subtriangular, rounded at the sides 
posteriorly, the humeri dentiform, obliquely truncated in front; punctate-striate, the punctures sub- 
quadrate, the interstices closely rugulose, 3, 5, 7, and 9 narrowly costate, the ridge on 3 twice, and 
that on 5 once, broadly interrupted. Meso- and metasternum slightly depressed down the middle, the 
mesosternum nodose on each side in front. Ventral segments sparsely, finely punctate. Femora clavate, 
unidentate. Tarsal claws with a short stout tooth. 
Length 33-32, breadth 2-21 millim. (¢ 2.) 
Hab. Mexico, Jalapa (Hoge), Teapa (H. H. Smith). 
Two specimens. Near C. aristatus, but shorter and smaller, the prothorax sharply 
carinate towards the base, without prominences on the disc, the elytral cost less 
widely interrupted, the fascicles of clubbed sete wanting. 
163. Conotrachelus paleatus, sp. n. 
Subovate, robust, shining, nigro- or rufo-piceous, the antenne obscure ferruginous; the vestiture rather coarse, 
sparse, reddish or fulvous, slightly intermixed with white, somewhat fasciculate on the elytra, the short 
white hair-like scales on the latter, and those on the legs also, subsetiform, the head with a dense fulvous 
patch in front, the femora annulate, the anterior pair with a short fulvous streak at the base above. 
Head densely, rugulosely punctate, transversely depressed in front; rostrum ( $ ) moderately stout, curved, 
a little longer than the head and prothorax, sharply 5-carinate, the apex rugulosely punctate, ( @ ) longer 
and smoother, the apex sparsely punctured, the antenneg inthe ¢ inserted at about one-fourth, and in the 
@ at one-third from the tip, joints 1 and 2 of the funiculus subequal in length. Prothorax broader 
than long, much narrowed and constricted in front, deeply bisinuate at the base ; coarsely, rugosely 
punctate and also carinate, the narrow intervening rug becoming longitudinal towards the apex. Elytra 
subtriangular, less than twice the width of the prothorax, deeply sinuate in front, the disc transversely 
depressed below the base, the humeri rounded; coarsely seriate-punctate, the interstices narrow, rugulose, 
3, 5, 7, and 9 costate throughout, the others usually a little raised posteriorly. Meso- and metasternum 
depressed down the middle. Ventral segments coarsely, rather sparsely punctate. Femora strongly 
clavate, unidentate. Posterior tibive slightly hollowed and ciliate at the apex within in the g. Tarsal 
claws with a short tooth. 
Length 44-53, breadth 23-3 millim. (¢ @.) 
Hab. Nicaracua, Chontales (Janson: 2); Panama, Volcan de Chiriqui (Cham-. 
pion: o 2). 
Eight specimens, one only being from Nicaragua and that having the elytra broader 
at the base than the others. ‘The sparse vestiture, except for the dense fulvous patch 
on the front of the head, the shining surface, the subtriangular (or subcordate) elytra, 
with costate alternate interstices, &c., will help to distinguish this species from others 
with a depressed meso- and metasternum, the depression in C. paleatus extending a 
little further back in the female than in the male.
