CRATOSOMUS. 7 
shape, the prothorax and elytra fasciate, the prothorax narrowed behind and granulate 
on the disc, the elytra interruptedly seriato-foveolate. 
7. Cratosomus pulverulentus, sp. n. (Tab. I. figg. 12, 12a.) 
Subovate, shining, black ; sparsely clothed with minute or small, cinereous, piliform scales, which are partly 
hidden by a somewhat dense, ferruginous, mealy secretion. Head closely punctate, carinate between the 
large, rather narrowly separated eyes, the vertex shallowly sulcate; rostrum very stout, strongly arcuate, 
depressed at the sides towards the base, rugulosely punctate, becoming much smoother beyond the middle. 
Prothorax transverse, constricted and much narrowed in front, the sides arcuately converging from the 
middle; densely, minutely punctate, except along a smooth narrow median line, without trace of 
tubercles. LElytra moderately long, subtriangular, much wider than the prothorax; rather coarsely 
seriate-punctate, the interstices closely, minutely punctate, 3 with an exceedingly large, smooth, conical 
tubercle below the base, 8 with a large, outwardly-directed, conical tubercle at the shoulder, and 9 with 
a smaller tubercle below it, the disc transversely swollen and a little smoother across the middle and less 
distinctly so towards the apex, the apices slightly swollen. Beneath very shining, finely punctate ; 
ventral segments 1 and 5 deeply suleate down the middle. Pygidium rather broadly exposed beneath. 
Femora clavate, unidentate. 
Length 21, breadth 9 millim. (<.) 
Hab. Panama, Bugaba (Champion), Chiriqui (Zrétsch). 
Two males, one with the rusty-red mealy secretion almost covering the depressed 
portions of the elytral surface. The tubercle below the base of the third elytral 
interstice is very large, and the outwardly-directed conical tubercle at the shoulder 
is also large and prominent. C. pulverulentus approaches the S.-American 
C. varicosus. 
8. Cratosomus aspersus, sp. n. (Tab. I. fige. 13, 13 a.) 
Elliptic, black, thickly clothed with small, piliform, fulvo-cinereous scales, the tubercles bare. Head closely, 
very finely punctate, sulcate between the very large, narrowly separated eyes; rostrum arcuate, depressed 
and closely punctate at the base. Prothorax transverse, rapidly narrowed from the middle forwards ; 
dull, closely, minutely punctate, with a small, oblong, shining tubercle on the disc towards the 
apex. Elytra much wider than the prothorax, rather long, subtriangular, obtusely bidentate at the 
tip, the humeri prominent ; somewhat deeply striate, the strize with oblong, subquadrate, moderately 
coarse, approximate punctures, the interstices closely, minutely punctate, 1, 3, 5, and 7 with numerous, 
and the others with one or more, large, flattened, smooth, scattered tubercles. Beneath shining, very 
finely punctate; ventral segment 5 depressed down the middle. Pygidium arcuate and narrowly 
exposed beneath. Jemora clavate, each with a short tooth. Intermediate and posterior tibise strongly 
sinuate. 
Length 244, breadth 102? millim. (9.) 
Hab, Panama, Chiriqui (Trétsch). 
One example. Near the Brazilian C. 60s, Gyll., but with the elytral tubercles more 
numerous and smaller and the apical teeth shorter. There is a specimen from Ibague, 
Colombia, in the British Museum, that probably belongs to the same species: it has 
the vestiture yellower and on the prothorax condensed into a broad, transverse, inter- 
rupted, subquadrate patch at the base. .
