ampliatis, apices versus leviter attenuatis, supra grosse puiictatis, 
bicostatis. Long. 2-3 lin. c3' . 
Head short, forehead convex, tawny testaceous ; antenniferous 
tubercles and two broad stripes behind them, united on the oc- 
ciput, black. Antennae twice the length of the body, black, the 
fourth joint, with the exception of the apex, pale testaceous ; 
clothed with short setae, the basal joint furnished beneath with 
a fringe of long hairs. Thorax scarcely convex, lateral promi- 
nences placed at a short distance from the base ; black, with a 
silky fulvous vitta on each side. Elytra depressed, shoulders 
obtuse, lateral carina proceeding thence prominent, but not 
visible from above, slightly dilated from the middle to near the 
apex, then more suddenly attenuated, apex sinuate-truncate with 
the sutural angle rounded and external angle produced into a 
stout tooth ; surface clothed with erect brown setse, coarsely 
punctured, except near the apex, and traversed by two faintly 
elevated costse, both of which disappear before reaching the apex. 
Prosternum reduced to a very narrow thread ; mesosternum also 
extremely narrow. Abdomen blackish, clothed with grey pile. 
Legs moderately slender, basal joint of the posterior tarsi a little 
longer than the remaining joints taken together; black; coxseand 
basal halves of the thighs tawny testaceous. 
Ega, rare. I met with two examples only of this pretty little 
species : its habits are probably very similar to those of C. cincti- 
pennis, it being found only on the leaves of trees in the shades 
of the forest. The depressed body, somewhat dilated elytra, and 
fringed basal joint of the antennae are so many points of approx- 
imation to the genus Sparna of Thomson (Sy sterna Ceram by ci- 
darum, Liege, 1864, p. 30), the species of which resemble the 
dilated forms of the family Lycidae. 
Genus Colobothea, Serville. 
Serville, Ann. Soc. Ent. Fr. 1835, p. 69. 
The typical forms of this genus are well known to all who 
occupy themselves with the study of exotic Coleoptera. They 
are known by their elongate, narrow, and compressed form of 
body — the vertical, deflexed sides of the elytra being separated 
from the dorsal surface by an elevated line, which proceeds from 
the ridge formed by the shoulders, and disappears before reach- 
ing the apex. The elongated basal joint of the antennae has the 
same outline as in the great body of the Acanthocinitae previously 
described. The anterior coxae are somewhat globular, and the 
acetabular suture is quite closed ; both pro- and meso-sterna are 
plane, the former being very narrow and the latter subquadrate, 
narrowed behind. The apical segment of the abdomen is not
