48 RHYNCHOPHORA. 
antennal grooves in both sexes rapidly descending and closed behind; antenne inserted slightly before the 
middle of the rostrum, joint 2 of the funiculus distinctly shorter than 1. Prothorax transverse, more or 
less rounded at the sides, narrowed and constricted in front; coarsely or finely granulate, and with a short, 
conspicuous, median carina at the middle. Elytra moderately long, one-half wider than the prothorax, 
subparallel in their basal half, conjointly rounded at the apex, flattened on the disc, with the third 
interstice often more or less costate, the humeri rounded; seriate-punctate, the interstices granulate and 
usually transversely rugose. Metasternum long, foveolate at the sides. Ventral segments somewhat 
closely, finely punctate, the fifth with a sharply-defined, deep, narrow sulcus down the middle in both 
sexes, the first furnished with two backwardly-projecting matted tufts of fulvous piliform scales at the 
middle behind in the ¢. 
Length 63-9, breadth 24-34 millim. 
Hab. Mexico (Sallé), Ventanas in Durango (Forrer), Jalapa, Cordova (Hége); 
GuatTeMaLA, Chacoj, Teleman, Mirandilla, Cerro Zunil (Champion); Nicaragua, 
Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui (Champion). 
The twenty-one specimens referred to this species agree in baving the fifth ventral 
segment sulcate down the middle and the second joint of the funiculus shorter than 
the first; but there is great variation amongst them in the sculpture and coloration 
of the prothorax and elytra (the smoothest specimens having the prothorax straighter 
at the base and less rounded at the sides), and in the relative length and sculpture of 
the rostrum. The extreme forms were obtained with the more typical ones at several 
localities, and there can be little doubt that they all belong to one variable species. 
H. sulcifer resembles H. trinotatus in general facies, except that it is much smaller. 
77. Hilipus penicillatus, sp. n. (Tab. IV. figg. 7, 2; 7a, part of under 
surface, 3.) 
_Oblong-ovate, black or piceous, the legs and antennze sometimes partly rufescent; thickly clothed with small, 
rounded, greyish-brown scales, the prothorax with intermixed piliform scales, the elytra more or less 
mottled with ochreous or whitish towards the apex, and each with a transverse or A -shaped velvety-black 
mark on the disc beyond the middle, and a short black streak or triangular mark near the suture before 
the apex, the scales on the scutellum whitish ; the under surface and legs thickly clothed with ochreous 
or whitish scales, those on the pleura mostly rounded, the others piliform. Head rugosely punctate, 
shallowly foveate between the eyes, the latter somewhat narrowly separated ; rostrum in the ¢ very stout, 
moderately curved, not longer than the prothorax, rugosely punctured and tri- or quadricarinate at the 
base, in the 2 a little longer and smoother, the antennal grooves descending to the lower angle of the eye 
and closed behind ; antenne inserted near the apex of the rostrumin the ¢, further back in the @, joints 
1 and 2 of the funiculus subequal in length. Prothorax transverse, convex, moderately rounded at the 
sides, constricted and narrowed in front, feebly bisinuate at the base ; rather coarsely granulate, without 
trace of median carina. Elytra one-half wider than, and three times the length of, the prothorax, parallel. 
in their basal half, subtruncate at the base, conjointly rounded at the apex, the humeri rounded and rather 
prominent ; seriate-punctate, the interstices transversely wrinkled, the third interruptedly costate, and all 
of them with smooth scattered granular elevations, each bearing a long decumbent seta. Metasternum 
and venter very minutely punctate, with scattered coarse punctures, these being deeply impressed on the 
second ventral segment; first ventral segment broadly produced in the middle behind in both sexes, and 
with two matted tufts of ochreous piliform scales in the middle at the apex in the ¢. 
Length 5-74, breadth 24-31 millim. (¢ 9.) .

Chiriqui (Champion).
