292 PHYTOPHAGA.—SUPPLEMENT. 
LUPRAEA (p. 359). 
Lupreza fulvicollis (p. 359). 
To the localities given, add :—Britisa Honpuras, R. Hondo (Blancaneauz). 
3. Luprea marginipennis. 
Narrow, parallel, fulvous ; the antenne, tibie, and tarsi black; head and thorax impunctate ; elytra testa- 
ceous, impunctate, the lateral margins, and the apex to a greater or less extent, black. 
Length 13-1? line. 
Head impunctate, fulvous, shining, the eyes large, the labrum piceous; antenne black, extending to two-thirds 
the length of the elytra, the fourth and following joints elongate-triangular in shape; thorax fulvous, 
transversely subquadrate, the sides rounded, the surface shining, entirely impunctate; scutellum 
triangular, fulvous ; elytra pale fulvous or testaceous, impunctate, shining, the sides, and a more or less 
distinct elongate sublateral patch at the apex, black ; underside and femora (the apex of the hind pair 
excepted) fulvous, the apex of the posterior femora and the tibie and tarsi black. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
In its structural characters L. marginipennis agrees in every respect with the other 
species of the genus, having very narrow elytral epipleure, an invisible prosternum, 
open anterior coxal cavities, &c., thus forming a link between the groups Halticine 
and Galerucine. 
PTOCADICA (p. 360). 
Ptocadica straminea (p. 360). 
Additional specimens of this species have been received from Bugaba and the Volcan 
de Chiriqui. These differ from the type and belong to two well-marked varieties :— 
1. Elytra with a transverse band at the base and an arcuate mark at the middle piceous. 
2. Elytra with a transverse band at the base only piceous. 
2. Ptocadica bifasciata. 
Yellowish-white ; the antenne, breast, and apex of the femora, and the tibiee and tarsi, black; thorax and 
elytra impunctate, the latter with a transverse band at the base and another below the middle, black. 
Length 2 lines. 
Hab. Costa Rica, Caché (Rogers). 
This species, of which only a single imperfect example has been obtained, closely 
resembles P. straminea in shape and in its structural characters ; but it is of a creamy- 
white colour, and the posterior band on the elytra is placed below the middle. 
APHTHONA (p. 360). 
4(a). Aphthona pacifica. - : 
Elongate, parallel, black, the head, thorax, and legs fulvous; antenne with short joints; thorax with an 
obsolete transverse groove ; elytra nearly impunctate. 
Length 13 line.
