1. Cratosomus annulipes, sp. n. (Tab. I. figg. 1, 1a.) 
Oblong-ovate, rather broad, black, opaque above (the tubercles excepted), moderately shining beneath ; tho 
head between the eyes, the prothorax with the anterior margin, the lower part of the flanks, and a patch 
on each side at the base, the scutellum, and the elytra with three broad, more or less connected, 
transverse, irregular fascie, the anterior one connected with an oblique humeral streak, thickly clothed 
with yellowish- or fulvo-cinereous, piliform scales, the rest of the upper surface black ; the under surface, 
femora, and tibie rather sparsely clothed with narrow yellowish-cinereous scales, the femora conspicuously 
annulate near the tip, the tarsi thickly clothed above with similarly-coloured hairs. Head finely 
punctate, broadly sulcate between the somewhat widely separated eyes, the groove extending upwards 
on to the vertex; rostrum almost straight, broad, flattened, rugulosely punctate and subcarinate, smooth 
at the tip. Prothorax transverse, rapidly narrowed from the middle; closely, minutely punctate, the 
disc broadly depressed in the centre, shortly carinate, and with several scattered, smooth, rounded 
tubercles. Elytra much wider than the prothorax, narrowing from a little below the base, the humeri 
swollen, the apices obtuse; finely punctate-striate, the interstices minutely punctate, flat, 1, 3, 5, and 7 
with scattered, smooth, rounded, subconical tubercles, the one near the base of 3 larger than the others. 
Beneath closely, finely punctate; ventral segment 1 broadly depressed down the middle in the ¢. 
Pygidium broadly exposed beneath in both sexes, with a short longitudinal carina at the tip. Femora 
clavate, each with a short tooth. 
Length 20-22, breadth 9-10 millim. (¢ 2.) 
Hab. Costa Rica (Van Patten), Miravalles (Underwood), Azahar de Cartago (Biolley) ; 
Panama, Chiriqui (T7rétsch). 
Five specimens. A close ally of the very variable C. punctulatus, but with fewer 
and much more conspicuous tubercles on the elytra; the prothorax with several 
scattered tubercles on the disc, the pallid vestiture of its upper surface reduced to two 
patches at the base and a line along the apical margin.
