ADDENDA ET CORRIGENDA. 
Stenocerus amazonae , Jekel, is the Sten. squarrosus , Lacord. in lilt. 
This last name should be preferable, as being not restrictive as the 
other, although the Amazons be the largest stream of the world. 
According to Dr. Gerstacker it is the true Sten. robuslus of Dejean 
Catal.; a very possible thing (though the meaning of that name be less 
applicable to this species than to Sten. testudo , Jekel), for, although 
M. Dupont repeatedly boasted of his free and continual access to 
the late Dejean’s cabinet, and of his whole collection being 'perfectly 
named upon that entomologist’s types, every one knows how much 
he has induced Dr. Burmeister to misapplication of specific names; 
therefore, I always very little trusted his determinations. 
Except the above-recorded, all the other species that have been 
described by various authors as belonging to that genus are of quite 
different generic forms, viz .:— 
1st. Stenocerus Garnotii , Guer., and Sten. tessellatus, Eyd. and 
Soul. Kev. Zool. 1841, p. 265, and Desm. (Voy. la Bonite) are 
two very closely allied species, bearing a certain outward likeness 
to Stenocerus , but should be ranged close to Dendropemon , Sch., 
by their having the rostrum broad, as much as the head flat, sub- 
quadratiform, or rather somewhat shorter than long, hardly narrowed at 
the base, thin in depth, subcarinifonn and somewhat rounded at 
the sides to the apex, which is slightly emarginate (indeed very much 
alike to that of Platyrhinus lalirostris , F.), with the insertion of the 
antennae infra-lateral, at about the middle of its length, in a groove 
rather deep, elongate, infra-lateral, transversely directed underneath ; the 
eyes are supra-lateral, rather large and convex, obliquely and sub- 
angularly biting in the forehead at the base of the rostrum. The 
antennae are very short and thin, not reaching to the middle of the 
thorax in all the female specimens I have seen, and scarcely longer 
in the single male with entire antennae I could inspect; the first 
joint is oblong, clavate, not visible from above ; second subglobose ; the 
remainder of the funiculus very slender, successively shorter; the club 
short, three-jointed ; first and second joints transversely triangular, much 
pointed inside; third rounded, flat. The remaining characters suf¬ 
ficiently developed in Guerin’s and Desmaret’s plates. ( Hylopemon , 
Jekel).
