36 RHYNCHOPHORA. 
strongly bisinuate at the base; the surface coarsely granulate, the elevations smooth and shining 
and transverse in shape on the disc, in the centre of which is a smooth oblong prominence. Elytra 
one-half wider than, and three times the length of, the prothorax, subtruncate ,at the base and 
subparallel thence to the middle, flattened on the disc anteriorly, the humeri rounded, the subapica 
callosities prominent, the apical portion somewhat abruptly declivous, the apices conjointly rounded ; 
deeply seriate-punctate, the interstices slightly convex and each with a scattered series of smooth 
tubercles. Beneath very sparsely, finely punctate, the sides of the metasternum foveolate ; metasternum 
short, deeply sulcate in the middle behind. Legs comparatively short; tibisze mucronate, the claw 
arising from near the outer angle. 
Length 83, breadth 4 millim. (2.) 
Hab. Costa Rica, Pital del Naranjo (Biolley, in Mus. Brit.). 
Two specimens. This species is perhaps nearest allied to H. asperatus, H. nevulus, 
and If. atrosignatus, but has relatively shorter and broader elytra, the black patch 
very large and laterally placed, a long rostrum, &c. The shorter prothorax, more 
parallel elytra, &c., separate it from H. decoratus. The white scales on the upper 
surface are chiefly confined to a space on the disc of the elytra beyond the middle, the 
scutellum, and a line down the middle of the prothorax. 
55. Hilipus trinotatus, sp.n. (Tab. III. figg. 15; 15, profile of head &c.) 
Elongate-ovate, black, the prothorax (except along the middle in front), scutellum, and elytra densely 
clothed with flavo-cinereous scales, the disc of the prothorax and of that of the basal half of the elytra 
mottled with brown, the elytra with a very large, subtriangular, sharply-defined patch at the sides a 
little beyond the middle and a common apical patch brownish-black ; the head, rostrum, under surface, 
and legs sparsely clothed with piliform greyish scales. Head foveate between the eyes, which are rather 
widely separated; rostrum exceedingly stout, moderately curved, about as long as the prothorax, 
closely punctured at the sides towards the base; antenna stout, inserted at about the middle of the 
rostrum, joints 1 and 2 of the funiculus subequal in length, the following joints short and moniliform, 
the club ovate and about as long as the last four joints of the funiculus united. Prothorax convex, 
about as long as broad, much rounded at the sides, constricted and narrowed in front and narrowed 
behind; the surface with widely-scattered, smooth, rounded granules, which become more crowded on the 
dise behind and are flattened in front. Elytra comparatively elongate, subparallel in their basal half, 
one-fourth wider than the prothorax, flattened on the disc, conjointly rounded at the apex, but with the 
sutural angles somewhat pointed, the humeri rounded; coarsely seriate-punctate, the interstices 
narrow, transversely rugose, and also very sparsely but conspicuously granulate. First ventral segment 
faintly depressed in the middle behind. ‘Tibia acutely mucronate, the curved apical claw also long. 
Length 133, breadth 5 millim. 
Hab. Nicaracva, Chontales (Belt). 
One specimen, probably a female. A very distinct species, not unlike H. jocosus, 
but more elongate, densely squamose (the scales completely hiding the sculpture, with 
the exception of the smooth granular elevations), the antenne stouter, with a shorter 
club, the prothorax more rounded at the sides, the anterior tibie strongly mucronate 
at the tip, &c. 
56. Hilipus jocosus. (Tab. III. fig. 16, 2.) 
Heilipus jocosus, Boh. in Schénh. Gen, Cure. iii. p. 180°.
