304 RHYNCHOPHORA. 
from a little before the base. Prothorax transverse, rounded at the sides, much narrowed and feebly 
constricted in front, sparsely granulate, the elevations transverse on the disc. Scutellum subcordate 
(narrow in one specimen), more or less squamose. Elytra a little wider than the prothorax, subcordate, 
slightly constricted before the middle, transversely depressed at the base, the apices produced, and in the 
S furnished with a pencil of ochreous hairs ; seriate-punctate, the interstices very sparsely granulate, the 
elevations unequal in size, the larger ones conspicuous. Ventral segments 3-5 in the d , and 3 and 4 
in the 9, smoother in the middle, 1 broadly depressed in the ¢. Mesosternum not raised between 
the coxee. Femora each with an acute tooth. 
Length 10-14, breadth 44-64 millim. (¢ 2.) 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
Found in plenty on the slopes of the Volcan de Chiriqui. The chief characters of 
this species are the small tuft of ochreous hairs at the apex of the elytra in the 3, the 
sparse granulation, the larger elevations on the elytra being conspicuous and each 
followed by a very short pallid seta, and the dense, uniform, brownish or brownish- 
ochreous squamosity of the upper surface.

Cholus albiventris, Chevr. Le Nat. iii. p. 482 (1881) *. 
Hab. Costa Rica! (Mus. Holm.). 
The type of this species, a female, which we figure, kindly lent me by Dr. Sjdstedt, 
is extremely like C. lewcogaster (of which the male only is known), but differs in its 
less elongate shape, the much longer, smoother, and sharply carinate rostrum, the 
more scattered, transverse granulation of the prothorax, the rounded scutellum, and 
the relatively broader and shorter elytra. 
30. Cholus leucogaster, sp. n. (Tab. XVI. figg. 9, 9a, 3.) 
Subrhomboidal, narrow, piceous, the rostrum and legs rufo-piceous, the tarsi ferruginous ; above thickly clothed 
with small, rounded, ochreous scales, the smooth granular elevations bare and shining ; the sides of the 
body beneath and the prosternum densely clothed with white scales, the vestiture of the rest of the under 
surface and of the legs sparse, white, and piliform. Head rugosely punctate ; rostrum moderately stout, 
curved, a little longer than the prothorax, rugulosely punctate and carinate to about the middle, and 
sparsely punctate and shining thence to the apex. Prothorax transverse, conical, rounded at the sides 
behind, closely, uniformly granulate. Scutellum oval. Elytra a little wider than the prothorax, and at 
the sides forming almost a continuous outline with it, subcordate, the apices somewhat produced ; seriate- 
punctate and also closely seriato-granulate, the granular elevations between, the punctures less prominent 
than those of the interstices. Ventral segments with a broad space down the middle very sparsely 
punctate, 1 shallowly, longitudinally depressed. Mesosternum flattened between the coxe. Femora 
each with an acute tooth. 
Length 103, breadth 44 millim. (¢.) 
Hab. Nicaracua, Chontales (Janson). 
One specimen. Less elongate than C. pallidiventris, the prothorax more rounded at 
the sides behind, the scutellum narrower, the elytra much more narrowed posteriorly, 
and with the granular elevations conical and separate one from another, the scales on
