32 RHYNCHOPHORA. 
have been obtained by us. Recognizable by the very large, posteriorly excised, 
velvety-black patch on the disc of each elytron beyond the middle, this patch bordered 
with a narrow line of ochreous scales, and sometimes followed by a small triangular 
one. The rostrum is stout, feebly curved, considerably longer than the prothorax in 
the male, smoother at the apex and still longer in the female, rugose and 5-carinate 
towards the base. The head is sulcate between the eyes, which are very narrowly 
separated. The prothorax and elytra are sparsely granulate, each of the smooth, 
tuberculiform, elytral elevations bearing a short decumbent seta; they have the surface 
clothed (except upon the velvety patch) with minute, rounded, brownish scales. The 
scutellum is clothed with whitish scales. The males have the metasternum and first 
ventral segment very broadly and shallowly depressed down the middle. 
48. Hilipus flavolineatus, sp. n. (Lab. III. figg. 7, 2; 7a, profile of head.) 
Oblong-ovate, opaque, black, somewhat thickly clothed with very minute, rounded, brown scales; the elytra 
each with a very large, oval, velvety-black, lateral patch, extending inwards to near the second row of 
punctures and limited internally by a line of pale ochreous scales, which is continued forwards round the 
humeri to the base of the sixth interstice, the scutellum also clothed with pale ochreous scales ; 
the under surface and legs very sparsely clothed with piliform ochreous scales. Head foveate between the 
eyes, which are rather widely separated ; rostrum dull, strongly curved, stout, considerably longer than 
the prothorax, sparsely, finely punctate, smoother towards the tip, with a smooth narrow space down the 
middle; antenne inserted at the middle of the rostrum, joints 1 and 2 of the funiculus subequal in 
length. Prothorax transverse, convex, rounded at the sides, abruptly constricted and narrowed in front, 
very sparsely granulate, the elevations transverse and not very prominent. Elytra one-half wider than 
the prothorax, sinuate at the base, subparallel to near the middle, conjointly rounded at the apex, but 
with the sutural angles somewhat pointed, the humeri rounded externally and concave in front; finely 
seriate-punctate, the punctures becoming coarse towards the base, the interstices (except upon the 
velvety patch) with a single, widely-scattered, irregular series of rather prominent granular elevations, 
each of which bears a short decumbent seta on its posterior edge. Metasternum very sparsely foveolate 
towards the sides. Ventral surface almost smooth, the first segment unimpressed. 
Length 11-12, breadth 5-53 millim. (@.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Two specimens. Not unlike the South-American H. zoubkofii, H. ocellatus, &c., 
but with the velvety-black patch on each elytron very large and lateral, the interstices 
each with a single series of scattered, setigerous, granular elevations. From H. intensus, 
which has similar minute scales on the upper surface, it may be distinguished by the 
more curved non-carinate rostrum, the much larger and differently-shaped velvety 
patches on the elytra (which are not bordered externally with a line of ochreous 
scales), the more widely separated eyes, &c. 
49. Hilipus nigromaculatus, sp.n. (Tab III. fig. 8.) 
Oblong-ovate, slightly shining, black, thickly clothed with narrow brown scales; the elytra each with a very 
large, oval, velvety-black, lateral patch, extending inwards to about the second row of punctures and 
limited internally by a line of ochreous scales; the under surface and legs sparsely clothed with piliform 
whitish or ochreous scales. Head foveate between the eyes, which are narrowly separated ; rostrum 
shining, curved, moderately stout, longer than the prothorax, punctured towards the base; antenne
