ARNITICUS.—HILIPINUS. 51 
2. Arniticus setiger, sp.n. (Tab. IV. fig. 11, 2.) 
Oblong-ovate, nigro-piceous, the upper surface variegated with ochreous, whitish, and black scales, the whitish 
scales forming a triangular spot on the scutellum, a small spot at the base of the fifth interstice of the 
elytra, and a narrow, curved, transverse, more or less distinct fascia on the disc of the latter beyond the 
middle ; the under surface and legs clothed with ochreous scales. Head rugose, feebly foveate between 
the eyes, which are rather narrowly separated; rostrum stout, moderately curved, about one-third longer 
than the prothorax, longitudinally rugose, smoother at the tip in the  ; joint 2 of the funiculus nearly 
twice as long as 1. Prothorax transverse, rounded at the sides, much narrowed anteriorly and slightly 
constricted before the apex ; sparsely granulate and with an abbreviated median carina. Elytra about 
one-half wider than the prothorax, subparallel to near the middle, conjointly rounded at the apex, the 
sutural angles somewhat pointed, the humeri rounded ; deeply seriate-punctate, the interstices somewhat 
convex, each with a widely scattered series of granular elevations, these being furnished posteriorly with 
a long, semierect, stout, pallid seta. Venter broadly depressed down the middle towards the base in 
the g. Tibie with the claw arising from the inner angle in the ¢, mucronate in the 9. 
Length 93-10, breadth 4-4$ millim. (¢ 2.) 
Hab. Mexico, Frontera in Tabasco (Hége); British Hoypuras, Rio Hondo 
(Blancaneaux) ; Panama, Volcan de Chiriqui, Bugaba (Champion). 
‘Var.? The curved whitish fascia on each elytron reduced to a small spot on the middle of the disc, the 
interstitial granules larger and fewer in number. (<d.) 
Hab. Nicaracua, Chontales (Belt). _ 
Seven examples of the typical form, and two of the variety, which should perhaps 
be treated as a separate species. Very like A. cingulatus, but less elongate, the 
prothorax more rounded at the sides and without distinct vitte, the elytra with fewer 
granular elevations in the interstitial series and these bearing longer and stouter sete. 
From A. perturbatus (Boh.) it differs in having a more distinctly carinate prothorax and 
longer elytral sete. 
HILIPINUS, gen. nov. 
Scrobes partly visible from above, open and extending forward on the inner side beneath, in the ¢ reaching 
to at least the middle of the rostrum, and receiving the whole or part of the funiculus, and sometimes the 
club also, in the @ receiving the basal joint only of the funiculus. Tibial claw arising from: the inner 
apical angle of the tibia in the d, and from near the middle of the apical margin in the Q, the inner apical 
angle mucronate in the 2. Tibie usually more or less sulcate on their outer edge, and the rostrum 
also on either side above. The other characters as in Hilipus. 
This group of species, the characters of which were in part noticed by Lacordaire 
(Gen. Col. vi. p. 457, nota 4), includes Heilipus ascius and I. cadivus, Germ., 
H. corruptor, #. dahlbomi, H. maculosus, H. lacordairei, H. granicostatus, H. medi- 
oximus, H. egenus, H. bartels, H. friesi, H. integellus, H. punctatoscabratus, and 
H. ziegleri, Boh., H. mortuus, Thoms., H. occultus and H. tetraspilotus, Pasc., and 
others. ‘The males are easily distinguishable from those of the allied genera by the 
extended antennal grooves on the underside of the rostrum; the females, however, 
have these grooves \/-shaped, as in both sexes of Arniticus, from which genus they 
may in most cases be separated by the laterally sulcate rostrum or the more or less
