200 PHYTOPHAGA. 
the elytra with a very broad black oblong annulus on the outer part of the disc, extending to far beyond 
the middle, more or less obliquely truncate behind, and enclosing a moderately large, rounded, common 
flavous patch, which is sometimes divided at the suture by a narrow black line ; the antenne flavous, the 
apical joint infuscate at the tip; beneath and the legs flavous. Antenne moderately long, slender, the 
apical five joints a little thickened, joint 3 slightly longer than 2. Prothorax about twice as broad as 
long, broadly expanded and reticulate at the sides and in front ; the disc obsoletely canaliculate and with 
a few minute scattered punctures behind, very feebly depressed on either side of the median lobe at the 
base. Elytra about three times as long as the prothorax, and very much wider than it, very deeply 
emarginate at the base, and with prominent rather sharp humeri; the disc moderately convex, hollowed 
at the sides behind the humeral callus, and foveate before the middle, with an impressed sutural stria 
posteriorly, somewhat closely seriate-punctate—the punctures moderately fine towards the suture, coarse 
at the sides, and almost obsolete on the flavous apical portion,—the interstices smooth and flat; the 
margins broadly expanded, becoming gradually narrower towards the apex, smooth and reticulate, 
separated from the disc by a row of moderately deep fovee. Claws simple. 
Length 53-53, breadth 5 millim. 
Hab. Nicaraaua, Chontales (Belt, Janson) ; Costa Rica (Sailé). 
Seven specimens. Allied to C. myops, C. puella, &c., but larger, with a broad, 
entirely black annulus, which is less obliquely truncate behind, and the scutellum 
black. In one specimen the annulus is transversely truncate behind. 
34. Coptocycla balteata, (Tab. XI. fig. 3.) 
Rotundate, convex, shining; the prothorax with the disc black, the margins flavo-hyaline ; the scutellum 
flavous, narrowly bordered with fuscous; the elytra with a broad black annulus extending round the disc 
and nearly reaching the apex, the enclosed portion rufo-testaceous, with rows of fuscous dots showing 
through from the inner side, the margins flavo-hyaline; the legs and antenn# flavo-testaceous; the 
under surface black, the prothorax at the sides and the abdomen flavo-testaceous. Antenne moderately 
long, slender, the apical five joints a little thickened, joint 8 not longer than 2. Prothorax one-half 
broader than long, broadly expanded and reticulate at the sides and in front, feebly sinuate at the base 
on either side of the median lobe; the disc with a few rather deep punctures at the base towards the 
sides, and obliquely grooved on either side of the median lobe. Elytra much wider than, and about two 
and a half times as long as, the prothorax, deeply emarginate at the base, with moderately prominent 
rather obtuse humeri; the disc convex, shallowly foveate in the centre before the middle and bifoveate 
at the base, with rows of very fine punctures which become coarse towards the sides and almost obsolete 
towards the apex (the sutural row excepted), the interstices smooth and flat; the margins broadly 
expanded, becoming very narrow at the apex, smooth and reticulate, separated from the disc by a row of 
deep fovee. Claws simple. 
Length 44, breadth 3? millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. This species resembles C. atroannulus in colour, but it is only about 
half the size of that insect ; it also differs in having the prothorax grooved on either side 
of the median lobe at the base, the black annulus extending almost to the apex of the 
elytra, the disc of the prothorax entirely black, that of the elytra more distinctly 
foveate before the middle. The broad black annulus extending nearly to the apex, in 
connection with the small size and rotundate shape, separates C. balteata from the 
other allied species here enumerated.
