292 RHYNCHOPHORA. 
Prosternum tuberculate between the anterior coxe. Mesosternum slightly protuberant between the 
intermediate cox. Metasternum and the first two ventral segments broadly depressed down the middle 
and thickly pubescent in the d. Legs rather elongate ; femora each with an acute tooth 
Length 15-16, breadth 53-63 millim. (3 Q.) 
Hab. Nicaragua, Chontales (Belt, Janson, Richardson). 
Three males and three females. The elongate shape (approaching that of Solenopus), 
the comparatively short rostrum, the subcarinate, granulate, bivittate prothorax, the 
rugose elytra, with small scattered patches of scales, the tuberculate prosternum, and 
the thickly pubescent metasternum and first two ventral segments of the 3, sufficiently 
distinguish C. tuberculifer. The structure of the prosternum is similar to that of the 
species of the genus Rhinastus. 
2. Cholus nigrofasciatus. (Tab. XV. figg. 5, 5a, 2.) 
Sternoxus nigrofasciatus, Chevr. Bull. Soc. Ent. Fr. 1879, p. xxviii *. 
Cholus delectans, Jekel, in litt. 
Hab. Mexico (Mus. Brit.), Toxpam (Sallé+); Guaremata, Cerro Zunil (Champion). 
Of this species there are five specimens in our collection, three of which are from 
Mexico. It is somewhat rhomboidal in shape, and thickly clothed with small, narrow, 
greyish or ochreous scales, except upon the vertex ; the prothorax and elytra are 
granulate, the smooth elevations being seriately arranged on the latter, the elytra with 
a more or less distinct median fascia and usually a spot on the subapical callosities 
sparsely squamose or almost bare. In the male the rostrum is rugose and carinate 
towards the base and the first two ventral segments are broadly depressed down the 
middle. The intermediate and hind femora are armed with a long tooth, that on the 
anterior pair being small or almost obsolete. ‘The mesosternum is raised between the 
intermediate coxe. 
3. Cholus leucozona, sp.n. (Tab. XV. figg. 6, 6a, 2.) 
Subelliptic, dull, nigro-piceous, the rostrum and legs rufo-piceous ; thickly clothed with minute brownish- 
ochreous scales, the elytra with a deeply impressed, narrow, transverse fascia before the middle densely 
clothed with white scales, and an indeterminate space before and behind this almost bare, the vestiture 
of the legs and the last three ventral segments sparse and whitish. Head closely punctate, rugulose and 
foveate between the eyes ; rostrum curved, stout, much longer than the prothorax, in the d rugulosely 
punctate and carinate at the base, and more sparsely punctate thence to the tip, smoother in the @. 
Prothorax transverse, rounded at the sides, rapidly narrowing from a little before the base, feebly 
constricted in front, uniformly granulate. Scutelium closely punctured, subcordate. Elytra considerably 
wider than the prothorax, subcordate, slightly constricted before the middle; seriato-granulate and also 
indistinctly seriate-punctate, the interstices each with a row of slightly smaller elevations, the granules 
on the anterior half here and there transverse and confluent, the narrow depressed space occupied by the 
white fascia densely, minutely punctate. Mesosternum transversely raised between the coxe. Ventral 
segments 1 and 2 broadly flattened down the middle in the ¢,, 3-d sparsely punctate and partially bare. 
Femora each with an acute tooth. 
Length 12-14, breadth 53-65 millim. (¢ 2.)
