20 RHYNCHOPHORA. 
disc, the apices conjointly rounded, the humeri rounded ; coarsely seriate-punctate, the discoidal 
interstices transversely rugose, the punctures of the striw thus appearing to be transversely contluent, 
Ventral segment 1 broadly depressed along the middle in the male, and narrowly 80 in the female. 
Length 11-14, breadth 43-5? millim. (d 2.) 
Hab. Paxama, Bugaba, Volcan de Chiriqui (Champion). 
One pair. Very like H. longirostris, but with a much stouter and shorter rostrum, 
even in the female; the prothoracic vitte more distinctly defined; the markings of 
the elytra very similar, except that there are larger patches of white scales at the base 
in the present insect. 
24. Hilipus mixtus, sp. n. (Tab. Il. figg. 11, ¢; 11, profile of head.) 
Oblong-ovate, shining, piceous, the tarsi and the tip of the rostrum rufescent; the prothorax with an 
ill-defined oblique vitta on each side formed of intermixed white and fulvous scales, the disc with 
scattered ochreous pubescence; the elytra with various oblong or rounded fulvous spots, which tend to 
form an oblique fascia below the shoulders, a short transverse fascia before the middle (the two together 
forming an irregular curved band), a complete subapical arcuate fascia, and an apical patch, the rest of 
the surface with very small, scattered, whitish spots and narrow, minute, ochreous scales; the under 
surface, rostrum, and legs with scattered, narrow, white scales. Head very deeply foveate between the 
eyes, which are narrowly separated ; rostrum stout, curved, about one-third longer than the prothorax, 
thickly punctured towards the base, almost smooth at the tip; antenne inserted towards the apex of the 
rostrum, joints 1 and 2 of the funiculus subequal in length. Prothorax a little longer than broad, much 
narrowed in front, rounded at the sides before the middle; coarsely confluently punctate, and with 
indications of a smooth, raised, median line. Elytra convex, one-half wider than the prothorax, widest 
about the middle, and slightly narrowing thence to the base, conjointly rounded at the apex, the humeri 
rounded ; seriate-punctate, the interstices transversely rugose. Ventral segments 1 and 2 very broadly 
depressed down the middle. 
Length 14, breadth 54 millim. (¢-) 
Hab. Panama, Volcan de Chiriqui 5000 feet (Champion). 
One specimen. Very like H. atomarius and H. longirostris, but with a shorter 
rostrum, a longer prothorax, and more convex elytra, the latter widest at the middle 
and narrowing forwards. The differences are too great to admit of its being treated as 
the male of H. longirostris, the female only of which is known. ‘The present species 
is also a close ally of the South-American /H. apiatus, Oliv., which is a larger insect 
and has the elytral spots irregularly scattered over the whole surface, and nowhere 
ageregated so as to form fasciz. 
25. Hilipus guttiger, sp.n. (Tab. II. figg. 12, ¢; 124, profile of head.) 
Oblong-ovate, shining, piceous or rufo-piceous, the prothorax (except at the base), head, rostrum, and legs 
sometimes rufous; the prothorax with an ill-defined, narrow, oblique, whitish vitta on each side and for 
the rest clothed with scattered ochreous pubescence ; the elytra with a broad curved stripe on the outer 
part of the disc extending from the base to about the middle (in one specimen divided into two), and a 
very large rounded patch immediately before the apex, the latter extending to the suture, but not to the 
apical angle, and enclosing a bare spot on the subapical callus, ochreous or pale ochreous, the rest of 
the surface with scattered, minute, whitish or ochreous scales, which fill up the depressions of the surface 
and form small spots; the under surface, legs, and rostrum with scattered, narrow, whitish scales. Head 
foveate between the eyes, which are narrowly separated; rostrum about three-fourths longer than the .
