570 RHYNCHOPHORA. 
prothorax, narrowing from the base, the humeri swollen; punctate-striate, the interstices punctulate, 
3, 5, 7, and 9 sharply costate. Beneath closely punctate. Mesosternum prominent, horseshoe-shaped. 
Leys rather slender ; femora feebly clavate and sharply unidentate ; tibixe more or less curved externally. 
Length 33-4, breadth 2-24, millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Ten specimens. The rather dense vestiture, the long, erect, scattered sete, the 
subfasciate elytra, the comparatively short rostrum, the prominent mesosternum, and 
the sharply unidentate femora chiefly distinguish 2. unidentatus. 
Sect. B. 
51. Kubulus nigrodiscus, sp. n. (Tab. XXVIII. fige. 8, 8a, 3.) 
Subovate, convex, moderately shining, nigro-piceous, the antenn» ferruginous, the legs (the anterior femora 
excepted) rufo-piceous; the prothorax with a very large, transverse, rounded patch on the disc densely 
clothed with small black scales, the other portions of its surface with cinerous scales; the scutellum 
fulvous ; the elytra somewhat sparsely clothed with brownish scales, these becoming cinereous at the 
base, each elytron with a small, transverse patch on the disc behind the scutellum, a spot on the shoulder 
beneath, and a few very small widely scattered spots on the basal half, white; the rest of the vestiture 
fulvous, slightly intermixed with whitish, that of the abdomen coarse and piliform, the femora subannulate, 
the upper surface also set with short, scattered, erect sete, the legs closely, coarsely setose. Head rather 
small, rugosely punctate, the eyes moderately distant; rostrum stout, curved, scarcely longer than the 
prothorax, rugosely punctate to the tip, and also finely carinate, the antenne inserted considerably beyond 
the middle, joint 2 of the funiculus elongate, the club ovate. Prothorax very much broader than long, 
the sides rapidly, arcuately converging from the base, the ocular lobes feebly developed ; densely, minutely 
punctate, obsoletely carinate down the middle, and feebly granulate at the sides, Elytra wider than the 
prothorax, subtriangular, transversely convex ; seriate-punctate, the interstices 3, 5, 7, and 9 sharply 
costate. Beneath coarsely punctate. Mesosternum broad, the walls raised anteriorly, ventral segments 
1 and 5 thickly clothed with very long fulvous hairs (except down the middle and at the sides). Legs 
moderately long, rather stout; femora unidentate, the intermediate and posterior pairs subclavate ; tibie 
almost straight, angulate at the base externally ; all the tarsi densely tomentose beneath, and clothed 
with long scattered hairs. 
Length 6,5, breadth 3£ millim. (¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen, in very fresh condition. The very large, rounded, velvety-black patch 
on the prothorax, and the rather sparsely squamose elytra, with small patches of coarse 
white scales near the scutellum and beneath the humeri, distinguish the present species 
from all its allies. There are two allied unnamed South-American forms in the Pascoe 
collection at the British Museum. 
52. Eubulus atrodiscus, sp. n. 
Ovate, convex, black, the antennez and the tips of the tarsi ferruginous ; the prothorax with a very large, 
transverse, rounded patch on the disc clothed with small black scales, the rest of the vestiture brownish 
and cinereous intermixed, the elytra also set with short, scattered, semierect sete; the legs setulose. 
Head rugulosely punctate, the eyes well separated; rostrum stout, strongly curved, a little longer than 
the prothorax, rugosely punctate and feebly carinate, the antennz inserted near the tip, joint 2 of the 
funiculus a little longer than 1, the club ovate, acuminate. Prothorax short, rounded at the sides, much 
narrowed in front, the sides subparallel behind ; densely, finely punctate, and obsoletely carinate. 
Scutellum small. Elytra much wider than the prothorax, subtriangular, transversely convex; seriate-
