CHLAMYS. 167 
Specimens from the above localities agree fairly well with Lacordaire’s description of 
C. stictica; they vary a good deal ‘iin colour, the thorax being pale and almost un- 
spotted in some examples, and in others covered with black spots which occasionally 
form two lateral bands and a short central stripe at the base; nearly all have a pale 
bright flavous or ferruginous stripe on the disc of the thorax. The middle portion of 
the thorax is raised into a round moderate elevation, which is not channelled but has 
generally a small oblong depression at the top: this is evidently the principal character 
by which C. stictica may be known. It is somewhat doubtful whether the Guatemalan 
specimens belong to the same species, as they have the elytra constricted at the middle 
and are also more elongate ; they agree, however, in the main points with the Mexican 
insect. 
25 (a). Chlamys bugabensis. (Tab. XX XIX. fig. 24.) 
Pale flavous ; thorax with four tubercles, the disc with a transverse dark band; elytra closely punctured, with 
a subsutural ridge on the disc extending from the middle to the apex and five tubercles, a transverse band 
at the base and the tubercles greenish. 
Length 2 lines. 
Head flat, with a few fine punctures, pale flavous; antenne flavous; thorax finely granulate and punctured, 
the posterior portion raised into a rounded feeble elevation, the top of the elevation being broadly but 
shallowly channelled and furnished with four small tubercles, the disc with a transverse strongly sinuate 
dark greenish band which does not extend to either margin ; scutellum black, impunctate; elytra sub- 
quadrate, constricted at the sides, closely punctured in longitudinal rows, with a distinct ridge running 
obliquely from the middle of the base towards the suture near the apex, where it is more strongly raised, 
and numerous tubercles—two near the basal margin, one near the suture before the middle, a transverse 
one at the middle, and two others at the sides below the middle,—the tubercles, a spot on the shoulder, 
and a transverse band at the base, not extending to the middle, dark olive-green ; the elytral epipleurse 
at the base and some small spots at the sides of the breast dark olive-green, the rest of the underside and 
the legs bright flavous. 
Hab. Panama, Bugaba (Champion). 
The coloration and sculpture of this species distinguish it readily enough from the 
allied forms. ‘The elytra, in addition to the more prominent subsutural costa, have two 
other coste (only visible in certain lights), one placed near the shoulder and one 
towards the apex near the lateral margin. 
25 (s). Chlamys semifulva. (Tab. XL. fig. 7.) 
Head and thorax fulvous; the latter with two more or less distinct brown bands, its elevation subglobose ; 
elytra with longitudinal and transverse ridges, brownish-fuscous, with a narrow fulvous transverse band 
near the apex; legs and abdomen fulvous. 
Length 1 line. 
Head entirely fulvous, rugose; antenne fulyous; thorax finely rugose-punctate, the elevation finely reticulate, 
subglobose, and with a narrow channel on the top bounded on either side by a fine raised ridge, the 
surface bright fulvous, the elevation with two dark brown stripes behind and a small spot on either side 
laterally ; scutellum stained with fulvous; elytra subquadrate, slightly narrowed posteriorly, dark fuscous, 
with a narrow fulvous or flavous transverse band near the apex, four very distinctly raised sinuate 
longitudinal ridges—the first subsutural, S-shaped, and joined below the middle to the second ridge, the 
latter extending upwards to the middle of the base and downwards to near the apex, where it turns
