18 RHYNCHOPHORA. 
as the body beneath and the legs, clothed with widely-scattered; narrow, white scales, the pro-, meso-, and 
metapleura with a line of larger ochreous scales. Head almost impunctate, deeply foveate between the 
eyes, which are narrowly separated ; rostrum curved, considerably longer than the prothorax, moderately 
stout, with a few scattered punctures only at the sides towards the base ; antenne inserted far before the 
middle of the rostrum, joint 1 of the funiculus longer than 2. Prothorax about as long as broad, rounded 
at the sides anteriorly, coarsely, confluently punctate, and sometimes with a narrow smooth space or 
raised line down the middle. Elytra rather convex, about one-half wider than the prothorax, sub- 
parallel at the base, conjointly rounded at the apex, the humeri rounded ; seriate-punctate, the interstices 
smooth and flat. Ventral seements 1 and 2 deeply depressed down the middle in the male. 
Length 11-144, breadth 4-5} millim. (¢ Q.) 
Hab. Costa Rica (Van Patten); Panama, Volean de Chiriqui 4000 feet (Cham- 
pion). 
Six examples. Easily distinguishable from all the other Central-American species 
of the genus by the network of narrow lines of ochreous scales on the upper surface, 
those on the prothorax enclosing a triangular space on each side, and those on the 
elytra here and there connected on the disc, enclosing large triangular spaces, except 
towards the apex, where the lines become tortuous. The South-American H. mysticus, 
Pasc., is an allied form, but differs from the present species in having the upper surface 
smoother, the femora partly red, and the sinuous lines on the elytra differently arranged, 
not forming a zigzag line on the disc of each. 
20. Hilipus clathratus, sp.n. (Tab. IIL. figg. 7, ¢; 74, profile of head.) 
Oblong-ovate, shining, pitchy-black, the rostrum and the legs and antenne in part rufescent; the prothorax 
with a rather narrow ochreous vitta on each side, which curves inwards at the apex; the elytra with 
various sharply-defined ochreous lines—two of these enclosing a very large, common, rhomboidal space on 
the dise before the middle, the anterior line sending off a branch in front to meet the prothoracic vitta, 
the posterior line followed by two transverse ones (one oblique and the other curved),—and the outer 
and apical margins, a curved streak behind the subapical callus, and the punctures of the striew also, 
more or less clothed with similarly-coloured scales ; the rest of the upper surface with widely-scattered, 
narrow, ochreous, and the under surface and legs with whitish, scales, the pleura and each of the ventral 
segments 1-4 at the sides in front with lines of larger ochreous scales. Head deeply foveate between 
the eyes, which are rather narrowly separated; rostrum very nearly twice as long as the prothorax, 
rather slender, feebly curved, smooth, with a few scattered punctures only at the sides towards the base ; 
antenne inserted at about the middle of the rostrum, joint 1 of the funiculus nearly twice as long as 2. 
Prothorax broader than long, rounded at the sides and much narrowed in front, very coarsely confluently 
punctate, and with a smooth, raised, median line anteriorly. Hlytra one-half wider than the prothorax, 
parallel at the base and narrowing thence to the tip, conjointly rounded at the apex, the humeri rounded; 
coarsely seriate-punctate, the interstices smooth and flat. Ventral segments 1 and 2 broadly and 
shallowly depressed down the middle. 
Length 113, breadth 43 millim. (<.) 
Hlab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen. A very distinct species, with ochreous lines on the elytra, as 
in H. areolatus (though very differently arranged), and a very long feebly curved 
rostrum.
