COPTOCYCLA. 217 
Numerous examples. This species exactly resembles C. circumnotata, Boh., from 
the Amazons, in colour; but differs from it in the more transverse prothorax and the 
less deeply emarginate base of the elytra, the elytra with the punctures on the middle 
of the disc more remote from each other. The annulus on the elytra is usually faint. 
In one specimen from Bugaba the apical four joints of the antenne are black above. 
A closely allied insect from Brazil (incorrectly labelled Charidotis cognata, Boh.) is 
contained in the Baly collection. 
Some of the species placed in Charidotis by Boheman have similarly formed antenne. 
The shorter annulus on the elytra (when present) will distinguish C. evanescens from 
C. proxima.

Boheman’s description of this species, the type of which is before me, was based 
upon a pallid example with the annulus on the elytra obliterated. One of the three 
examples found by myself in Guatemala has the annulus sharply defined, one shows 
the outline of it towards the base, and the third resembles the type. In the first of 
these (from Zapote), the prothorax has a broad transverse patch in the middle 
posteriorly, divided down the centre by a flavous line and not quite reaching the base ; 
and the elytra have a rather narrow stripe on the outer part of the disc, extending 
nearly to the middle and then obliquely converging inwards to the suture, black, 
becoming castaneous posteriorly (forming with the marking on the prothorax a 
hexagonal annulus), the suture (except at the apex) and the annulus on the inner side 
dilute rufescent. The elytra are foveate in the centre before the middle. The antenne 
have their third joint not longer than the second. The claws are angularly dilated at 
the base. a 
A specimen from Caché, Costa Rica (Rogers), seems to belong to the pallid variety 
of this species ; but it has the discoidal fovea of the elytra almost obsolete. 
We figure two Guatemalan specimens—one (fig. 6) showing the narrow annulus, the 
other (fig. 7) agreeing with the type. — 
72. Coptocycla diluta. (Tab. XII. fig. 8.) 
Subrotundate, convex, dilute flavo-testaceous, shining; the prothorax with an indistinct transverse dilute 
olivaceous patch in the middle before the base, this being divided in the centre ; the elytra with a rather 
narrow similarly-coloured annulus on the outer part of the disc, extending round the base to the scutellum 
and obliquely converging inwards beyond the middle but not nearly reaching the suture; the antenna, 
legs, and under surface flavo-testaceous. Antennee moderately long, slender, the apical five joints a little 
thickened, joint 3 short, not longer than 2, 4 and 5 elongate. Prothorax about twice as broad as long, 
broadly expanded at the sides and in front, rather deeply sinuate at the base on either side of the median
