CHOLUS. 295 
punctured at the base, smoother towards the tip. Prothorax broader than long, subconical, granulate, 
the elevations fattened and here and there confluent. Scutellum subcordate, rather convex, closely, 
finely punctate. Elytra subcordate, the sides at the base forming an almost continuous outline with those 
of the prothorax, the sculpture similar, but with the elevations irregularly, transversely confluent, 
the seriate punctures indistinct. Beneath with scattered, small, shining, bare spots, and for the rest 
densely squamose. First ventral segment feebly depressed down the middle in the d. Mesosternum 
transversely convex between the cox. Legs rather long; femora each with an acute tooth. 
Length 15-22, breadth 7,,-11 millim. (d ¢.-) 
Hab. Costa Rica, Limon (Biolley, in Mus. Brit.); Panama, Volcan de Chiriqui 
3000 to 4000 feet (Champion). 
Eight specimens. This insect resembles C. vidwatus in size and shape, but differs 
from it in the less rugose elytra, and in the denser vestiture of both the upper and 
under surfaces, the transition in the colour of the scales being very abrupt laterally.

Cholus viduatus, Pasc. Journ. Linn. Soc., Zool. xi. p. 469°. 
Hab. Nicaragua, Chontales! (Belt, Janson, Richardson). 
A large species of rhomboidal form and shining black colour, the prothorax and 
elytra closely, irregularly granulate (the elevations on the latter transversely confluent), 
and both with numerous, small, scattered, dense patches of white scales, the rest of 
the surface with a fine whitish pubescence between the smooth prominences. The 
mesosternum is strongly raised and tuberculiform between the coxe. ‘The apical 
margin of the elytra is finely crenulate. The femora are each armed with an acute 
tooth. 
11. Cholus leucostictus, sp. n. (Tab. XV. figg. 13, 13a, 2.) 
Subrhomboidal, rather broad, black, shining, the prothorax usually with two spots on the disc, and the elytra 
with three or four scattered spots on the disc and one below the base beneath, densely clothed with small, 
oval, white scales, the vestiture of the under surface and legs whitish, sparse, very fine, and piliform. 
Head finely punctate, feebly foveate between the eyes; rostrum stout, curved, longer than the prothorax, 
rugulosely punctate at the sides, smoother along the centre and towards the apex. Prothorax transverse, 
rounded at the sides, constricted and much narrowed in front; the surface minutely punctate, granulate 
at the sides, the granulation becoming flattened and almost obsolete on the disc. Scutellum subcordate, 
finely punctate. Elytra wider than the prothorax, subcordate ; seriate-punctate, the interstices obsoletely 
granulate on the disc, the granulation becoming more distinct towards the sides and apex, the apical 
margin finely crenulate. Mesosternum convex between the coxe. First ventral segment depressed down 
the middle, the depression extending along the second also in the g. Intermediate and posterior femora 
each with a short tooth, the anterior pair unarmed. 
Length 17-19, breadth 77-9 millim. (d 2.) 
Hab. Costa Rica (Van Patten). 
Three rather worn specimens, apparently including both sexes, This is a form of 
the Nicaraguan C. vidwatus, from which it differs in having the prothorax and elytra 
much smoother, with very few white spots, and the anterior femora without trace of 
a tooth.
