8 RHYNCHOPHORA. 
9. Cratosomus cuneatus, sp.n. (Tab. I. figg. 14, 14a; 15, var.) 
Elongate-rhomboidal, shining, black; thickly clothed above with small, piliform, cinereous scales, the 
prothorax with two large spots on the disc and another on each flank, and the elytra with the shoulders 
and various irregular spots and sinuous transverse streaks, black ; the vestiture of the femora, tibiee, and 
under surface very sparse and fine. Head finely punctate, broadly sulcate between the somewhat widely 
separated eyes, the groove extending upwards on to the vertex; rostrum strongly arcuate, flattened, 
finely punctate, and subcarinate towards the base, the antenne inserted at about the middle. Prothorax | 
subconical, a little broader than long, slightly constricted in front; densely, minutely punctate, obsoletely 
carinate anteriorly. Elytra much wider than the prothorax, elongate-triangular, conjointly rounded at 
the apex ; coarsely punctate-striate, the interstices minutely punctate, somewhat convex, flat at the tip. 
Beneath very finely punctate; ventral segment 5 foveate in the 9, and with a deep transverse depression 
in the g. Pygidium of the ¢ broadly, that of the Q narrowly, exposed beneath. Femora clavate, each 
with a short tooth. . 
Prothorax with two black spots on each flank, the dorsal spots a little smaller; the elytra, except 
towards the apex, with the black partly denuded spaces more elongate and slightly raised, clustered into 
two irregular transverse fasciee (one at, and the other before, the middle), the interstices 3 and 5 each 
with an oblong bare prominence below the base. (Fig. 15.) 
Length 17-19, breadth 7-8 millim. (¢ 2.) 
Var. 
~ 
Hab. Guatemata, Cerro Zunil (Champion); Costa Rica, Azahar de Cartago (Under- 
wood). 
A pair from Guatemala and a female from Costa Rica, the latter belonging to the 
varietal form. This insect may be recognized by its rather narrow, elongate-rhomboidal 
form, the irregular black patches on the elytra, the strongly curved rostrum, &c. There 
are no definite tubercles on either the prothorax or the elytra, though the alternate 
interstices of the latter are sometimes raised below the base. 
10. Cratosomus bidens, sp. n. (Tab. I. figg. 16, 16a; 168, anterior leg.) 
Subovate, black, opaque above, slightly shining beneath; the head, the prothorax with the base, a small spot 
on the flanks, and an oblong patch near each hind angle, the scutellum, and the elytra with a transverse 
humeral patch (extending inwards to the scutellum), thickly clothed with narrow, piliform, cinereous 
scales ; the rest of the upper surface with scattered minute scales, the vestiture of the legs and under 
surface closer, longer, and cinereous. Head closely, minutely punctate, the eyes very large and 
subcontiguous ; rostrum arcuate, finely punctate, becoming much smoother towards the tip. Prothorax 
transverse, flattened on the disc posteriorly, much narrowed in front; closely, minutely punctate, the 
disc with a small tubercle on each side at about the middle. Elytra moderately long, subtriangular, 
bidentate at the apex; punctate-striate (the punctures coarse, deep, and oblong, smaller at the base and 
towards the apex), the dorsal interstices with scattered smooth conical tubercles, which are most numerous 
on | and 3, the shoulders also tuberculate beneath. Beneath finely punctate; ventral segment 5 depressed 
down the middle posteriorly. Pygidium broadly exposed beneath. Femora bidentate, the teeth distant 
one from another, the inner tooth on the intermediate and posterior pairs rather large. Tibie strongly 
sinuate. 
Length 233, breadth 114 millim. (<¢.) 
Hab, Panama, Chiriqui (Zrétsch). 
One specimen, assumed to be a male. Near C. dejeani, Gyll. (= bombina, Oliv., 
Herbst), but with the femora bidentate, the elytral tubercles almost confined to the 
dorsal region (inconspicuous on the shoulders and more numerous along the suture),
