46 RHYNCHOPHORA. 
base, conjointly rounded at the apex, the humeri rounded; seriate-punctate and finely granulate, the 
interstices transversely wrinkled. Metasternum deeply foveate along the outer edge. Venter convex 
towards the base, segments 1-4 almost smooth, unimpressed. 
Length 11-18, breadth 43-5} millim. 
Hab. Nicaracva (Sallé), Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui 
(Champion). 
Six examples, probably including both sexes, the males of some of the allied forms 
(H. bioculatus and H. cecus) also having the first ventral segment unimpressed. ‘The 
present species is very like H. nigrofasciatus; but is narrower and less robust, the eyes 
are not contiguous above, the prothorax has two white spots at the base and is more 
coarsely granulate, the outer edges only of the metasternum are foveolate, &c. 
73. Hilipus pulverulentus, sp.n. (Tab. IV. fig. 4.) 
Oblong-ovate, shining, rufo-piceous, the head, rostrum, and tarsi rufescent; the upper surface (the head 
excepted) somewhat thickly clothed with tawny scales, the legs and under surface with long piliform scales. 
Head foveate between the eyes, which are somewhat widely separated ; rostrum moderately stout, curved, 
one-half longer than the prothorax, closely and finely punctured towards the base; antenne inserted at 
about the middle of the rostrum, joints 1 and 2 of the funiculus subequal in length, the club longer 
than the five preceding joints united. Prothorax much broader than long, convex, rounded at the sides, 
constricted and considerably narrowed in front, strongly bisinuate at the base; the surface, except for a 
narrow space along the middle behind, finely and rather sparsely granulate, the interspaces densely, 
minutely punctate. Elytra one-fourth. wider than the prothorax, strongly sinuate at the base, subparallel 
in their basal half, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices 
transversely wrinkled and finely granulate. First ventral segment faintly depressed down the middle 
behind. 
Length 124, breadth 5 millim. 
Hab. Nicaragua, Chontales (Belt). 
One specimen, probably a female, though the first ventral segment is distinctly 
impressed in the middle. Chiefly distinguishable by the dense uniform tawny clothing 
of the prothorax, scutellum, and elytra, the strongly-sinuate base of the latter, and the 
finely-granulated upper surface. H. pulverulentus is closely allied to the South- 
American H. pertyi, Schonh. (=rufipes, Boh.), but differs from it in having the 
squamosity of the elytra uniformly tawny (instead of variegate with black and white), 
and the elytra themselves less elongate. 
74. Hilipus fulvisquamis, sp.n. (Tab. IV. fig. 5, 2.) 
Oblong-ovate, moderately shining, rufo-piceous, the rostrum and legs sometimes rufescent; the upper surface 
somewhat thickly clothed with bright fulvous piliform scales, which on the pronotum are concentrated 
into two broad oblique vitte: (a space down the middle and the flanks being very sparsely squamose); the 
elytra with a small spot or transverse mark on the disc a little beyond the middle, sometimes extending 
outward to near the margin, and usually a small spot immediately behind the subapical callosities, black ; 
the legs and under surface sparsely clothed with whitish and fulvous piliform scales. Head foveate 
between the eyes, which are somewhat widely separated ; rostrum feebly curved, stout, and about one- 
fourth longer than the prothorax in the ¢, a little longer and more slender in the 9, rather closely 
punctured towards the base; antenne inserted a little before the apex of the rostrum in the @, 
further back in the @, joint 2 of the funiculus longer than 1(¢), or 1 and 2 subequal in length (2 ).
