COPTOCYCLA. 219 
the anterior border of the humerus,—a transverse or oblique mark on the inner part of the margin about 
the middle, two small spots on the outer part of the dise—the anterior one oblong and in a line with the 
discoidal fovea, the posterior one at the middle,—a small spot on the discoidal fovea, and the sutural edge 
very narrowly, black or blackish ; the antennz testaceous, with the apical five joints black ; beneath black, 
the sides of the prothorax and of the abdomen testaceous; the legs testaceous. Antenna elongate, 
extending far beyond the base of the prothorax, joints 3-6 slender, 7-11 thicker than those preceding, 
3 very little longer than 2, Prothorax twice as broad as long, smooth, slightly depressed at the base on 
either side of the broad median lobe, broadly expanded and reticulate at the sides and in front. lytra 
very much wider than, and about three times as long as, the prothorax, sinuate-emarginate at the base ; 
the disc strongly transversely convex anteriorly and somewhat abruptly declivous beyond, very deeply 
foveate in the centre before the middle and longitudinally depressed at the sides below the humeral callus, 
very finely and rather remotely seriate-punctate, the punctures becoming coarser towards the sides, the 
interstices smooth and flat; the margins broadly expanded, becoming narrow at the apex, smooth, reti- 
culate, separated from the disc by a row of coarse fovex, subhyaline from a little below the base; the 
humeri prominent anteriorly, obtuse. Claws angularly dilated at the base. 
Var, The transverse humeral patch faint or dilute, the other elytral markings partly or entirely obliterated. 
Length 6-63, breadth 5-53 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Numerous examples. This species is perhaps nearest allied to C. profligata, Boh. ; 
but it is much larger and more convex, and the elytra are relatively wider anteriorly, 
with more prominent humeri and a deeper discoidal fovea. The elytra are almost 
gibbous below the base. 
75. Coptocycla duplex. (Tab. XII. figg. 11; 114, profile.) 
Subtriangular, very convex, shining, rufo- or flavo-testaceous, the elytra with a broad ramus of this colour at 
the base extending across the margins to the humeri; the dilated margins of the prothorax, and those of 
the elytra from a little below the base, flavo-hyaline; the antennz flavo-testaceous, with the apical four 
joints (the tip of the eleventh excepted) black; the legs and under surface flavo-testaceous. Antenne 
moderately long, the five outer joints thicker than those preceding, joint 3 a little longer than 2 and 
shorter than 4. Prothorax nearly twice as broad as long, moderately sinuate at the base on either side 
of the broad median lobe, the latter obliquely grooved at the sides and with a few fine punctures; the 
margins broadly expanded. Elytra very much wider than, and about three times the length of, the pro- 
thorax, narrowing from the base, the base rather deeply emarginate, the humeri prominent, obtuse; the 
disc very convex, rather abruptly declivous posteriorly, deeply foveate in the centre before the middle and 
bifoveate at the base, hollowed at the sides behind the humeral callus, with rows of widely separated fine 
punctures, which are sometimes fuscous in colour, the interstices smooth and flat; the margins moderately 
expanded, becoming very narrow at the apex, smooth and reticulate, separated from the disc by a row of 
deep fovee. Claws angularly dilated at the base. 
Length 6-62, breadth 5-53 millim. 
Hab. Mexico, TapachuJa in Chiapas (Hége) ; Guatemaua, Las Mercedes (Champion). 
Three examples, all from the Pacific slope, and from not very distant localities. 
This species resembles C. ventricosa, Boh.; but it is much smaller and the elytra are 
not abruptly gibbous. From the somewhat similarly-coloured C. proftigata, Boh., it 
may be known by its larger size, subtriangular shape, and more gibbous elytra, the 
latter much more deeply foveate on the disc.
