99.4 PHYTOPHAGA. 
Var. a. The spots on the prothorax almost obliterated, and the fascie on the elytral margins abbreviated. 
(Var. a, Boh.) . 
Hab. Nicaragua, Chontales (Belt).—CoLomBIA. 
Var. 3. The elytra with a broad common transverse patch at the base, a smaller transverse mark below it, the 
two connected along the suture, two or three fascie below the middle, and some scattered spots, black or 
piceous ; the scutellum infuscate or piceous. (Fig. 20.) 
Hab. Panama, Bugaba, Caldera, and David (Champion). 
The typical form is not uncommon in Chiriqui. The variety 6 (fig. 20), of which 
three specimens only have been obtained, is connected with the type by intermediate 
gradations; it closely resembles C. dissimilis, but may be known from it by the addi- 
tional fascia on the elytral margins.

Coptocycla lugubrina, Boh. Monogr. Cassid. iv. p. 477°. 
Hab. Panama, Bugaba (Champion).—Cotomnt1a 2 3 (Chevrolat *). 
One specimen, agreeing perfectly with a specimen from Chevrolat’s collection (pro- 
bably the type) in the British Museum. In this species the prothorax has a large 
subtriangular black patch, marked with three yellow spots—one median and one on 
either side (the latter not surrounded with black externally in the type); the scutellum 
black; the elytra with the disc, and two transverse fascize extending across the margins 
nearly to the outer limb, black, the black deeply excised on either side of the disc at 
the middle.

Hab. Mexico 2%, Toxpam, Cordova, Orizaba, Playa Vicente (Sallé 1), Teapa in Tabasco 
(H. H. Smith); Nicaragua, Chontales (Bel¢, Janson). 
Sent in numbers from Teapa. This insect is closely allied to C. plicata; but differs 
from it in having the black dorsal patch of the elytra more or less emarginate on either 
side at the middle, and usually with two broad black rami extending outwards from it 
(to a greater or less extent) on to the margin, but not reaching the outer limb. The 
elytra also have some small yellow or testaceous spots near the suture, which are rarely 
absent. In pallid examples the disc of the prothorax and of the elytra is castaneous. 
The scutellum is yellow. The antenne are flavous, with the tip of the apical joint 
black. 
Two species were confused by Wagener? under the name semilobata: the Mexican 
specimens are referable to C. stali; those from Colombia (one of which has been kindly
