down the elevation), the sides ferruginous (but the edge of the darker portion strongly dentate near the 
base, so that the two colours are not divided by a straight line) ; elytra very slightly narrowed posteriorly, 
rather flattened, of a very opaque dark greenish colour, more strongly punctured than the thorax, with 
the following prominences—an elongate tubercle near the suture before the middle, another, but shorter, 
one at the middle of the base, two rows of tubercles, placed one below the other and extending obliquely 
downwards from the shoulder to the middle of the suture, a strongly raised conical tubercle close to the 
suture near the apex, and a smaller tubercle at the sides ; pygidium ferruginous, with two dark greenish 
spots near the apex ; legs ferruginous, the tibie with the apex more or less black or greenish. 
Hab. Panama, Volcan de Chiriqui (Champion). 
C. semilutea is well distinguished by its peculiar coloration, and cannot be mistaken 
for C. maculipes or its allies, owing to the absence of pubescence from the upper surface 
and the presence of rather numerous tubercles on the elytra; it seems somewhat allied 
to the Brazilian C. corrugata, Lac. Two specimens. . 
Chlamys insularis (p. 78). (Tab. XX XIX. fig. 19, var.) 
To the localities given, add:—Panama, Bugaba, Volcan de Chiriqui, David, Caldera 
(Champion). 
We now figure a Chiriqui specimen of one of the varieties of C. insularis, in which 
the thoracic and elytral tubercles are more strongly prominent than in the type. The 
general colour of the upper surface is either black with more or less fulvous tubercles, 
fulvous with the tubercles black, or entirely brownish-eneous; the amount of the 
fulvous colour of the thorax also varies; the legs are more or less spotted with fulvous.

The reference to the Plate was accidentally omitted on page 79. 
11 (a). Chlamys fulvomaculata. (Tab. XL. fig. 1.) 
Subquadrate, narrowed posteriorly, black ; the head, thorax, abdomen, and legs spotted with fulvous; thoracic 
elevation divided, each division trituberculate ; elytra metallic bluish, eneous, or black, strongly tuber- 
culate at the base and apex, the disc with a high oblique ridge; pygidium carinate, nearly smooth, 
Length 13-13 line. 
Evidently very variable in colour and also to some extent in sculpture; head black spotted with fulvous, or 
entirely fulvous, rather sparingly punctured ; antenne fulvous, the apical joints darker; thorax with a 
moderate elevation, the latter divided into two portions each of which is furnished with three tubercles 
placed triangularly, the lateral portion finely punctured and with one or two very obscure tubercles, the 
anterior portion almost entirely fulvous or only spotted with that colour; elytra with a large tubercle at 
the middle of the base and two others near the apex, and an oblique more or less interrupted ridge ex- 
tending from the shoulder towards the suture, where it forms a strongly raised transverse ridge; pygidium 
sparingly punctured, rather smooth, with a longitudinal central ridge ; legs fulvous, more or less spotted with 
fuscous; abdomen with some fulvous spots. 
Hab. Mexico, Cordova (Sallé); GuaTEMALA, near the city (mus. Stuttgart). 
In the single example from Mexico the thorax shows at the apex of each division of 
the elevation an oblique ridge, in front and also at the side of which a small round
