A common species in Central America. In fresh specimens the prothorax has an 
almost complete white ring on the disc of the prothorax—a character not mentioned 
by Boheman, and not visible in worn or dirty examples. The sculpture of the upper 
surface is rather variable and cannot be properly seen till the scales are removed. 
The dark median fascia of the elytra is usually distinct; the alternate interstices are 
sometimes a little more raised than the others. I have seen the types of C. rubicun- 
dulus and C. pilosellus, Boh., the former being abraded and the latter densely 
squamose. C. ambiguus, Faust, from Venezuela, differs in having longer sete. 
C. hispidus, Lec., from Georgia, is probably synonymous with the present species. 
141. Conotrachelus hystricosus, sp.n. (Tab. XXI. figg. 3, 3a.) 
Subovate, shining above, dull beneath, piceous, the antenne, the tip of the rostrum, the tibie in part, and 
the tarsi ferruginous; thickly clothed with narrow, whitish and brown scales, those on the elytra 
oblong-oval in shape, the whitish scales on the prothorax condensed into a curved line on each side of the 
disc and a longitudinal one at the sides, each line being continued on to the base of the third and fifth 
elytral interstices, the elytra also with two transverse, connected, narrow whitish fascize towards the apex 
and indications of another below the base, the femora biannulate with white; the upper surface also set 
with numerous long, erect, stout, blunt, intermixed whitish and black setw, a number of the latter being 
clustered together at the middle of the third elytral interstice, the legs also setose. Head densely 
punctate; rostrum stout, feebly curved, as long as, or a little longer than, the head and prothorax, 
rugulosely punctate, the antenne inserted near the tip, Joints 3-7 of the funiculus transverse, 2 twice as 
long as 1. Prothorax strongly transverse, rounded at the sides, a little narrowed in front, feebly 
bisinuate at the base; finely punctate. Elytra subtriangular, rather convex, the humeri obliquely 
truncated ; seriate-punctate, the interstices rugulose and somewhat convex. Intermediate coxe narrowly 
separated. Mesosternum convexly protuberant in front. Ventral segments sparsely, finely punctate. 
Femora clavate, finely unidentate. Tarsal claws each with a long, slender, curved tooth, the two teeth 
almost meeting at their apex. 
Length 23-24, breadth 13 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Five specimens. A small species, distinguishable by the long, erect, stout, 
intermixed black and whitish sete on the upper surface (there being a cluster of black 
setae at the middle of the third elytral interstice), the squamose, variegate, non-costate 
elytra, the long, curved tooth of the tarsal claws, &c. It is more strongly setose than 
C. rubicundulus, and the sete are stouter than in C. ambiguus. 
142. Conotrachelus bicarinatus, sp.n. (Tab. XXI. figg. 4,4, 2.) 
Subovate, opaque, black ; the elytra obscure ferruginous, with a broad subapical fascia and the space between 
the first ridge and the suture black, the reddish colour extending to the sides of the meso- and 
metasternum, the antenne and the legs in great part ferruginous ; the vestiture very fine and short, that 
on the elytra mainly confined to the light-coloured portions of the surface (the dark portions being almost
