204 PHYTOPHAGA. 
We have received three specimens only of this species. CC. distorta closely resembles. 
C. dohrni, Boh., but differs from it in its smaller size, and in having the margins of the 
elytra rugulosely punctured. The elytra have a small transverse or oblong blackish 
spot on the suture before the middle. The antenne (which were mutilated in the 
specimen described by Boheman) have the apical joint, and the outer half of the 
preceding one, black ; the third joint is not longer than the second. 
44. Coptocycla biannulifera., (Tab. XI. figg. 12; 124, antenna.) 
Rotundate, convex, flavous, shining, the margins subhyaline; the eyes, and a narrow transverse patch at the 
base of the prothorax, black; the scutellum flavous ; the elytra with a narrow black stripe on the outer 
part of the disc, extending obliquely inwards a little beyond the middle and curved behind, and forming 
(with the mark at the base of the prothorax) an octagonal annulus, which is broadly bordered with dilute 
sanguineous within, and encloses a common flavous rounded patch ; the antenne testaceous, with the apical 
two joints slightly infuscate ; the legs and underside testaceous. Antenne short, scarcely extending beyond 
the base of the prothorax, slender, the apical five joints a little thickened, joint 3 shorter and thinner than 2, 
4 twice as long as 3. Prothorax nearly twice as broad as long, very broadly dilated and reticulate at the 
sides and in front, the disc feebly depressed at the base on either side of the broad median lobe, and with a 
few fine scattered punctures behind. Elytra about two and a half times as long as the prothorax, and at the 
sides forming almost a continuous outline with it, conjointly rounded at the apex, strongly bisinuate at the 
base, and with the humeri subacute and prominent in front; the disc convex, hollowed behind the humeral 
callus, with regular rows of fine, lightly impressed, rather remotely placed punctures, the interstices 
smooth and quite flat; the margins very broadly expanded, becoming narrow at the apex, smooth and 
reticulate, separated from the disc by a row of deep fovee. Claws simple. 
Length 73, breadth 63 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One example, probably of the male sex. Closely allied to Charidotis circulifera, 
Boh., the type of which is before me; but differing from it in the very much narrower 
black annulus (common to the prothorax and elytra), the shorter antenne, and the 
still finer seriate punctures of the elytra, the median lobe of the prothorax very faintly 
depressed on either side at the base (deeply, obliquely grooved in C. circulifera). 
Notwithstanding the short antenne, the species seems to me to be best placed in 
Coptocycla, near C. circumducta, C. incincta, &c. A closely-allied undescribed species 
from the Amazons is contained in the Baly collection. 
45. Coptocycla incincta. (Tab. XI. figg. 13; 134, antenna.) 
Coptocycla incincta, Boh. Monogr. Cassid. iv. p. 422”. 
Hab. Panama, Bugaba (Champion).—Amazons, Ega!. 
One specimen from Chiriqui, differing from the type of C. incincta in the Baly 
collection in having the antenne slightly longer and almost entirely testaceous, the 
punctures on the elytra coarser, and the annulus a little broader. This is one of 
several extremely closely allied species (C. concentrica, C. cincticulus, C. consimilis, and 
C. signorett, Boh.), some of which appear to have been described from single specimens, 
differing chiefly inter se in the form of the antenne and in the elytral punctuation.
