CHOLUS. 305 
the upper surface rounded. It cannot be satisfactorily referred to the still more nearly 
allied C. albiventris. 
31. Cholus pallidiventris, sp.n. (Tab. XVI. figg. 10, 10a, 3.) 
Oblong, subelliptic, somewhat flattened above, piceous or rufo-piceous; above thickly clothed with very small, 
narrow, ochreous scales, the elevations bare and shining ; the sides of the body beneath densely clothed 
with coarser white scales, the vestiture of the rest of the under surface and of the legs sparse, white, and 
piliform. Head rugosely punctate; rostrum stout, curved, a little longer than the prothorax, rugulosely 
punctate and carinate to beyond the middle, and closely punctate and shining thence to the apex, in the 
© smoother. Prothorax transverse, conical, a little rounded at the sides behind, closely granulate, the 
elevations transverse or crescentic in shape. Scutellum subcordate. LElytra a little wider than the 
prothorax, elongato-cordate ; seriate-punctate, the interstices seriato-granulate, the elevations here and 
there transversely confluent. Metasternum and abdomen with a broad space down the middle shining 
and very sparsely punctate, the ventral segments 1 and 2 depressed down the centre in the ¢. Meso- 
sternum flattened between the coxe. Femora each with an acute tooth. 
Length 114-13, breadth 43-53 millim. (¢ 2.) 
Hab. Nicaracva, Chontales (Belt, Janson). 
More elongate than C. aldiventris and C. leucogaster, the elytral granulation here 
and there transversely confluent, the scales on the upper surface narrower and smaller, 
the rostrum stouter, the body more flattened above. All three have the sides of the 
body densely clothed with white scales beneath. Four specimens. 
32. Cholus canescens. (Tab. XVI. figg. 11, lla, ¢.) 
Cholus canescens, Pasc. Ann. & Mag. Nat. Hist. (5) xvii. p. 420°. 
Subrhomboidal, narrow, black or piceous, the antennz, rostrum, and legs in part ferruginous; above and 
beneath, except upon the smooth, scattered, shining, granular elevations of the surface, thickly clothed 
with small, rounded, greyish-brown scales, which become paler beneath, the legs with elongate and piliform 
scales. Head rugosely punctate and foveate between the eyes; rostrum curved, rather stout, longer than 
the prothorax, in the ¢ rugulosely punctate in its basal half, and sparsely punctate thence to the apex, 
and subsulcate and feebly carinate towards the base, in the @ a little smoother, the antenne inserted 
before the middle in both sexes. Prothorax transverse, narrowing from near the base, the sides a little 
rounded posteriorly; sparsely, rather coarsely, granulate, the interspaces very minutely punctate. 
Scutellum subcordate or oblong. Elytra a little wider than the prothorax, oblong-subcordate, transversely 
depressed at the base, the apices obtuse ; seriate-punctate, the interstices each with a scattered series of 
irregular granular elevations, which are unequal in size, and also very minutely punctate. Anterior 
cox rather narrowly separated. Mesosternum flattened between the coxx. Ventral segments 1-5 in 
the ¢ and 3-5 in the ? with a broad space down the middle smoother and sparsely squamose, 
1 depressed in the ¢. Legs rather elongate; femora each with a sharp tooth; tibie mucronate at the 
inner apical angle and with a long claw at the outer angle. 
Length 73-10, breadth 33-47 millim. (¢ @.) 
Hab. Panama? (Mus. Brit.), Bugaba (Champion). 
Very like C. pilicauda, but smaller and narrower; the anterior and intermediate 
coxee less widely separated; the granulation of the prothorax and elytra not so scat- 
tered, the elytra less dilated anteriorly and more obtuse at the apex, without a tuft of 
hairs at the tip in the male. The scutellum varies in shape in both species. Five 
specimens have been found in Chiriqui.
