CAMPTOCHIRUS. 219 
piceous; the flattened or depressed portions of the surface mottled with grey, the elevated portions with 
velvety-black, pubescence ; the legs and under surface with grey and brownish, the scutellum with white, 
hairs. Head closely, finely punctate, subfoveate between the eyes, which are large, prominent, and 
narrowly separated ; rostrum stout, feebly curved, as long as or longer than the prothorax, shining, at 
the base closely and for the rest sparsely punctate, smoother in the Q, the antenne inserted at about 
two-thirds or three-fourths from the apex, joints 1 and 2 of the funiculus elongate, subequal in length, 
3-7 transverse, the club a little longer than 2-7 united. Prothorax slightly broader than long, some- 
what rounded at the sides, and constricted and narrowed towards the apex, and also narrowed behind, 
densely, finely punctate, with two transverse prominences on the disc before the middle, which are 
followed and preceded by a deep transverse groove. Elytra much wider than the prothorax, oblong- 
quadrate, flattened on the disc, the humeri angularly raised and dilated, the apices subtruncate ; 
punctate-striate, the interstices broad, flat, densely rugulose, and here and there nodose, the fifth with 
a conspicuous prominence before the middle, 4-6 broadly, conjointly lamellato-explanate at their point of 
termination, the dilated portion rounded externally, crenulate, and fringed with short, coarse hairs. 
Tibie strongly unguiculate, the anterior pair very obliquely truncate on their outer edge towards the tip, 
the apex itself abruptly truncate and ciliate. Intermediate and posterior femora each with a short tooth. 
Length 551,-6%, breadth 24-3 millim. (¢ 2.) 
Hab. Nicaragua, Chontales (Belt, Janson). 
Four specimens, no doubt including both sexes, one of them having a longer and 
smoother rostrum than the others. The more elevated portions of the surface are 
clothed with short bristly hairs. This species is a near ally of the S.-American 
C. chiragra (Fabr.), but has more angular humeri to the elytra, and the marginal 
dilatation larger. 
8. Camptochirus angulatus, sp.n. (Tab. XII. fig. 17.) 
Elongate, rather narrow, somewhat shining, black, the tip of the rostrum, the front of the prothorax, the 
shoulders and the apical margin of the elytra, and sometimes the disc in part, the antenne (the basal 
half of the club excepted), the intermediate and hind legs (the middle of the femora excepted), and the 
anterior tarsi and knees, more or less ferruginous; the elevated portions of the surface with velvety- . 
black, and the other parts mottled with grey, pubescence, with a few fulvous hairs intermixed, the 
vestiture of the scutellum white (in one specimen fulvous); the legs with fulvous and grey hairs. Head 
closely punctate; eyes large, very narrowly separated ; rostrum shining, as long as or longer than the 
prothorax, very sparsely punctate, a little longer and smoother in the 9, the antenne inserted at about 
one-third from the base, joints 1 and 2 of the funiculus subequal in length, 3-7 short, transverse, the club 
as long as the funiculus. Prothorax slightly broader than long, a little rounded at the sides, narrowed 
and constricted in front and narrowed behind, closely, finely punctate, the disc quadrinodose and shallowly 
grooved down the middle. lytra considerably wider than the prothorax, elongato-quadrate, the humeri 
swollen and subangular, the apices separately rounded; coarsely punctate-striate, the punctures deep 
and oblong in shape, the interstices more or less convex, rugulose, 3 and 5 here and there raised, 4—6 
conjointly and triangularly lamellato-explanate at their point of termination, the suture always with an 
elongate velvety-black patch at the middle. Anterior tibie obliquely truncate externally at the apex, the 
apex itself narrowly truncate and ciliate. Intermediate femora toothed, the posterior pair unarmed, 
Var.? The elytral interstices 3 and 5 not distinctly nodose, the apical dilatation subrectangular. 
Length 32-5, breadth 13-23 millim. (d @.) 
Hab. Mexico, Cerro de Plumas (Hége); GuateMmAta, Panajachel, San Gerénimo 
(Champion); Panama, Bugaba, Volcan de Chiriqui (Champion). 
Eight specimens from Panama and one from each of the other localities. The form 
of the subapical dilatation of the elytra varies in shape, it being acutely produced in
