60 RITYNCHOPHORA. 
Head densely punctate, foveate between the eyes, which are somewhat widely separated; rostrum 
stout, strongly curved, about as long as the head and prothorax, for two-thirds of its length densely 
rugosely punctate, and also carinate and laterally sulcate, the apical third minutely punctate and more 
shining, the antennal grooves extending shallowly forwards along the middle beneath ; joint 2 of the 
funiculus much longer than 1. Prothorax strongly transverse, convex, rounded at the sides, abruptly 
constricted and much narrowed in front, moderately bisinuate at the base; closely and rather coarsely 
granulate, carinate along the middle towards the apex. Elytra convex, a little wider than, and three 
times as long as, the prothorax, subparallel in their basal half, the base subtruncate, the humeri 
obtuse, the apices considerably produced and conjointly rounded, the subapical callosities not prominent ; 
coarsely and deeply seriate-punctate, the interstices smooth, rather convex, about the same width as 
the punctures, feebly, transversely wrinkled, and also very faintly granulate. Ventral segments sparsely 
and finely, the apex of the fifth coarsely, punctate, the first depressed along the middle. Tibize sulcate 
on their outer edge. 
Length 84, breadth 3} millim. (<d.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen, apparently somewhat abraded, the scales on the elytra not forming 
definite markings. This insect agrees with H. imtegellus in having grooves on the 
underside of the rostrum (except that they are shallower), as well as in the sulcate 
tibie; but it differs from that species and other allied forms in the short convex 
prothorax, the strongly curved rostrum, the subtruncate base of the elytra, the obtuse 
humeri, &c. The second joint of the funiculus, as in H. integellus, H. sulcicrus, 
and H. sulcirostris, is much longer than the first. ‘The coarsely granulate prothorax, 
the less elongate, posteriorly narrowed elytra, &c., separate AH. curvirostris from 
H. punctatoscabratus. 
16. Hilipinus occultus. (Tab. IV. fig. 23, 2.) 
Hilipus occultus, Pasc. Trans. Ent. Soc. Lond. 1881, p. 90°. 
Hab. Nicaragua, Chontales! (Belt); Costa Rica (Mus. Brit.); Panama, Bugaba 
(Champion). 
This insect is extremely like H. integellus, but it is smaller and less robust, the 
second joint of the funiculus is relatively longer (not, however, more than twice as 
long as the first, as stated by Pascoe), and the antennal grooves on the underside of 
the rostrum are shallower. Of the five specimens before me, one only is of the 
male sex. 
17. Hilipinus guatemalensis, sp. n. 
Oblong-ovate, slightly shining, piceous ; the elytra with a large irregular patch on the outer part of the disc 
before the middle, from which a branch extends forward to the base, a large somewhat cruciform patch 
on the disc at about one-third from the apex, and an apical spot, obscure ferruginous ; the prothorax 
with an indefinite sinuous vitta on each side, formed by scattered fulvous scales, the elytral markings also 
clothed with fulvous scales, and sometimes bordered with a few ochreous or whitish ones, the rest of the 
sparse squamosity of the upper surface obscurely coloured; the under surface and legs with widely 
scattered, piliform, whitish scales. Head rugosely punctured, obsoletely foveate between the eyes, which
