minutely punctate. Pygidium rugosely punctate, convex in the ¢. Prosternum: obsoletely sulcate 
towards the apex, the basal process flattened and somewhat explanate laterally, feebly tuberculate 
behind each coxa, and emarginate behind. 
¢. Antenne (fig. 19 a) with the scape clavate at the apex (as in the 2), joints 4-7 of the funiculus very short, 
widened, perfoliate, and setose, the club very large, flattened, oblong, and nearly as long as the funiculus ; 
anterior tarsi hairy and slightly dilated; anterior tibie (fig. 19 b) obliquely truncate at the apex within, 
the claw very small; metasternum and abdomen sparsely squamose down the middle, the first ventral 
segment shallowly sulcate. ; ; 
9. Antenne with a large acuminate-ovate club, the joints of the funiculus neither dilated nor setose ; 
metasternum and abdomen sparsely punctate and glabrous down the middle. 
Length 5-52, breadth 2-22 millim. (¢ 2.)

One male and two females. Very like the Brazilian insect identified by me as 
L. citriventris, Boh. ; but differing from it in the perfectly conical prothorax, the large, 
oblong, flattened antennal club of the male, and the obliquely truncated apices of the 
anterior tibize in this sex. 
3. Loboderes crassirostris.

Hab. Nicaraaua, Chontales 1. 
The unique type of this insect is the female of a species of Lobdoderes with the 
greater part of the vestiture of the under surface abraded, the prosternum only bearing 
small yellow scales. The elytra are subtriangular, being more widened at the base 
than in the allied forms, and the interstices are somewhat closely, minutely punctate. 
The under surface is densely, finely punctate, the punctuation being very fine on the 
meso- and metasternal side-pieces. ‘The basal portion of the prosternum is somewhat 
tumid, and arcuate-emarginate behind. ‘The legs are clothed with very fine, hair-like, 
yellow scales. ‘The antennal club is large, acuminate-ovate. 
4. Loboderes glabriventris, sp.n. (Tab. XIX. figg. 20, 204, 2.) 
Oblong, robust, subfusiform, glossy-black ; glabrous, a dense patch of small yellow scales at the sides of the 
third and fourth ventral segments excepted. Head minutely punctate, transversely depressed between the 
eyes; rostrum very stout, curved, about as long as the prothorax, sparsely punctate, striate at the sides, 
the antenne inserted at about the middle, the antennal club very large, acuminate-ovate, nearly as long 
as the funiculus. Prothorax as long as broad, conical, feebly constricted in front; closely, very finely 
punctate. Elytra rapidly narrowing from the rounded humeri, finely lineato-punctate, the sutural and 
outer strive only distinct, the interstices flat and with scattered very minute punctures. Pygidium large, 
rugosely punctate. Beneath coarsely, a broad space down the middle of the metasternum and abdomen 
sparsely and finely, punctate. Prosternum with a smooth triangular excavation at the apex, somewhat 
tumid along the middle, the basal process abruptly flattened, concave in the middle, almost smooth, and 
laterally margined, shallowly emarginate behind (fig. 20a). Tibise without visible uncus at the tip. 
Length 63, breadth 23 millim. (@.)
