CHOLUS. 293 
Hab. Guatemaua, Panzos and Chacoj in the Polochic Valley (Champion). 
Two specimens. Allied to C. nigrofasciatus, from which it differs in having the 
elytral fascia narrow, impressed, and densely clothed with white scales, the dark fascia 
in the former being unimpressed and not interrupting the surface-sculpture. 
4, Cholus alutaceus, sp.n. (Tab. XV. figg. 7, 7a, 3.) 
Subelliptic, a little flattened above, black, opaque, sparsely clothed with very minute ochreous scales and 
scattered, coarser, oval or piliform scales, these latter arising on the elytra from each of the punctures 
and from behind each of the granular elevations. Head closely punctate and feebly foveate between the 
eyes ; rostrum stout, curved, longer than the prothorax, in the ¢ rugulosely punctate, shallowly suleate, 
and dull in its basal half, becoming smoother and shining towards the tip, in the 2 smoother and more 
shining throughout. Prothorax transverse, rounded at the sides, much narrowed and feebly constricted 
in front, alutaceous, and finely, irregularly granulate, the granulation becoming very sparse at the sides. 
Scutellum subcordate, almost smooth. Elytra much wider than the prothorax, elongato-cordate, 
flattened on the disc beyond the middle, the subapical callosities prominent ; seriate-punctate, the space 
between each puncture obsoletely granulate, the interstices flat, alutaceous, each obsoletely seriato- 
granulate from the base to the apex. Beneath alutaceous, and sparsely, very finely punctate. First and 
second ventral segments broadly and feebly depressed in the middle in the ¢. Mesosternum strongly, 
transversely raised between the coxe. Femora each with an acute tooth, that on the anterior pair 
sometimes almost obsolete. 
Length 12-15, breadth 51-63 millim. (d @.) 
Hab. Guaremata, Purula and Sabo in Vera Paz (Champion). 
Six specimens, all from the dense forest-region of the Atlantic slope. The dull, 
alutaceous surface and the peculiar vestiture distinguish C. alutaceus at once from 
C. nigrofasciatus and other allied forms. 
5. Cholus levinodis, sp.n. (Tab. XV. figg. 8, 8a, 4, 3.) 
Subrhomboidal, nigro-piceous or rufo-piceous, the rostrum and legs sometimes reddish ; thickly clothed with 
minute, oval, brownish scales, the sides of the head and the base of the rostrum bordered with ochreous 
scales, the ventral segments 3 and 4 with a broad space down the middle, and the smooth, shining 
granules above and beneath, bare, the vestiture of the legs whitish or ochreous. Head closely punctate 
and foveate between the eyes; rostrum curved, stout, long, in the ¢ densely, rugulosely punctate and 
sulcate on either side above, and also carinate, in its basal third, and smoother beyond, in the 2 smoother 
from a little before the base. Prothorax transverse, subconical, rounded at the sides posteriorly, closely 
granulate, the elevations crescentiform on the disc. Scutellum subcordate. Elytra much wider than the 
prothorax, subcordate, somewhat flattened on the disc, slightly constricted below the base; closely 
seriato-granulate (the usual seriate punctures indistinct), the alternate interstitial series here and there 
interrupted by a larger, irregular or transverse prominence. Ventral segments 3 and 4 almost smooth 
along the middle, 1, 2, and 5 broadly depressed in the ¢. Mesosternum strongly, transversely raised 
and sublamellate between the coxee. Femora each with an acute tooth. 
Length 10-134, breadth 43-63 millim. (3 @ .) 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
Twenty-four specimens. Separable from C. pilicauda and others by the protuberant, 
lamellate mesosternum, the closely seriato-granulate elytra, the elevations on the 
alternate interstices here and there large and irregular in shape, and the finer 
squamosity.
