306 RHYNCHOPHORA. 
33. Cholus nigronotatus, sp. n. (Tab. XVI. figs. 12, 12a, 3.) . 
Oval, black, above (the head and the granular elevations excepted) thickly clothed with coarse, rounded, white 
scales, the prothorax with three large spots on the disc (one at the apex and two at the base) and two 
small spots on each flank (one of them touching the base), and the elytra with the base narrowly, a 
transverse patch at the middle of the disc, a large spot on the subapical callus, and various other small 
ed) also thickly clothed with 
spots, almost bare ; the under surface (the last three ventral segments except 
similar coarse scales ; the vestiture of the legs sparse, fine, and piliform. Head closely, rugosely punctate ; 
rostrum rather slender, curved, nearly as long as the elytra, rugosely punctured from the base to the 
apex and also longitudinally wrinkled, the antenne inserted at about the middle. Prothorax transverse, 
constricted and much narrowed in front, the sides rounded from the base, the surface coarsely granulate, 
the elevations on the disc crescentiform. Scutellum cordate. Elytra slightly wider than the prothorax, 
subcordate ; interruptedly seriato-foveolate, the interspaces coarsely, irregularly granulate, the elevations 
transversely or obliquely confluent at the middle of the disc. Beneath granulate and feebly punctate, 
the first two ventral segments depressed along the middle. Mesosternum not raised between the coxee. 
Legs rugose and granulate; femora each with an acute tooth. 
Length 9, breadth 44-43 millim. (d .) 
Hab. Nicaracva, Chontales (Belt); Panama, Bugaba (Champion). 
Two specimens. Easily recognizable amongst the Central-American Choli by its 
small size, oval shape, the uniform, coarse, whitish squamosity, interrupted by numerous 
bare spaces, the irregularly foveolate elytra, and the rugose rostrum and legs. It is, 
however, very like an undescribed species from Ecuador * in the Pascoe collection, but 
is narrower, the elytra are less rugose, and the white squamosity is differently arranged. 
The following is yet another allied form. 
34. Cholus nigromaculatus, sp. n. (Tab. XVI. figg. 13, 13.4, 3.) 
Oval, black, densely clothed (the granular elevations excepted) with rather coarse, rounded, whitish scales ; 
the prothorax with a broad median vitta, not reaching the base, a large spot on the disc on each side, and 
a smaller one on the flanks in a line with it, and the elytra each with a large transverse patch at the base 
(excised behind), a large spot on the disc a little beyond the middle, another one exterior to it, and a third 
near the apex, remaining of the ground-colour and thickly clothed with blackish scales, the vestiture of 
the median vitta of the prothorax only sparser, finer, and paler, like that upon the head, the latter with a 
line of white scales round the eyes, the last three ventral segments sparsely squamose ; the vestiture of 
the legs white and piliform. Head rugosely punctate; rostrum much longer than the prothorax, curved 
in the g rugosely punctured and feebly carinate, in the 2 a little smoother, the antennz inserted at 
about the middle. Prothorax transverse, constricted and much narrowed in front, the sides rounded 
from the base; coarsely, sparsely granulate, the elevations becoming closer along the middle of the disc 
Scutellum subcordate. Elytra much wider than the prothorax, cordate, seriate-punctate and very sparsely 
granulate, the elevations unequal in size, the punctures hidden by the dense vestiture. Beneath granulate 
and feebly punctate, the first two ventral segments depressed along the middle in the ¢. Mesosternum 
not raised between the coxee. Legs rugose; femora each with an acute tooth. 
Length 8, breadth 4 millim. (d 9.) 
Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion). 
One pair. Separable from C. nigronotatus by the denser vestiture, the more 
numerous and differently placed spots on the upper surface (these being nigro-squamose, 
instead of bare), the less rugose elytra and legs, the sparser granulation, and the 
* CO. forbesi, Pasc., in litt.
