230 PHYTOPHAGA.—SUPPLEMENT. 
basal four joints of the antenne fulvous (instead of three, as in the type), and the elytra 
obsoletely costate at the sides in the female sex. The elytra are strongly costate at the 
sides in the corresponding sex of most of the allied species, though they are not so in 
the single female of C. simplex from which my description was taken. The compara- 
tively fine punctuation arranged in single rows, which become almost obsolete near the 
apex, in connection with the fulvous tibie and tarsi, form the principal characters of 
distinction of C. simplex. 
20. Chalcophana brevicollis. 
©. Reddish-fulvous, the antenne (the basal two joints excepted), the apices of the tibia, and the tarsi black ; 
thorax narrow, closely punctured ; elytra closely semirugose-punctate, metallic green, the extreme lateral 
and apical margins fulvous ; prosternum very slightly emarginate. 
Length 3 lines. 
Head deeply punctured near the eyes, with a deep longitudinal median groove which ends in a fovea; clypeus 
very minutely punctured; antenne bluish-black, the basal two joints fulvous; thorax not more than one 
half broader than long, the sides obtusely rounded at the middle, rather strongly narrowed in front, the 
anterior angles distinct but not produced, the surface closely impressed with punctures of unequal size ; 
elytra deeply and closely punctured, the punctures near the suture arranged in semiregular rows, irregu- 
larly and coarsely rugose at the sides, and with an indistinct costa running downwards from the shoulder 
to the middle, the shoulders themselves prominent. 
Hab. Muxico, Jalapa (Hoge). 
A single female specimen. The comparatively narrow thorax and its close punctua- 
tion, the rugosely punctured elytra without costz (the ill-defined humeral one excepted), 
and the scarcely emarginate prosternum, separate this species from any of its similarly- 
coloured allies. 
21. Chaleophana quadricostata. 
9. Reddish-fulvous, the eight terminal joints of the antenne, the apices of the tibise, and the tarsi black ; 
head and thorax closely punctured; elytra metallic green, strongly geminate-punctate-striate, the sides 
with four longitudinal coste, the lateral and apical margins fulvous, the sutural angle dentiform. 
Length 3 lines. 
Hab. Guatemata, Sabo in Vera Paz (Champion). 
Two female specimens. Similar in coloration to C. godmani, C. hybrida, C. germari, 
&c., but differing thus :—The head and thorax are much more closely punctured; the 
elytral punctuation is strong and very closely placed, so that the geminate arrangement 
is indistinct except at the sides, where the double rows of punctures are divided by 
strongly raised coste (of these the inner one is more or less feeble); and the sutural 
angle of the elytra is produced into a tooth. C. puncticollis, Lefévre, from Colombia, 
is described as having black intermediate joints to the antenne and rufous tibie ; 
C. landolti, Lefévre, has a deep basal depression to the elytra, instead of a shallow one 
as in C. quadricostata. ‘The thorax in C. qguadricostata is rather short and strongly 
transverse.
