LAMPROSOMA. 179 
lobe not very acutely produced but somewhat rounded; the elytra are only moderately 
convex, broadly rounded at the apex, their punctuation distinct, the interstices also 
here and there extremely finely punctured ; the entire underside and the legs are black ; 
the prosternum is broader than long (this and the punctured elytral interstices distin- 
guish L. intermedium from several other closely allied forms) and finely punctured. In 
the specimen from La Parada the thorax is much more strongly punctured, and the 
elytral interstices are also much more distinctly (though finely) punctate ; this example, 
although of similar shape, is broader than the others ; it is probably a female of the 
same species. 
36 (a). Lamprosoma chiriquense. 
Very convex, narrowed behind, black; above bright metallic green; head and thorax very finely punctured ; 
elytra rather strongly punctate-striate ; prosternum slightly longer than broad, smooth. 
Length 3 lines. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This large-sized Lamprosoma, of which Mr. Champion obtained but a single spe- 
cimen, is closely allied to LZ. salvini and also to several species described by Lacordaire. 
In shape it is very different from L. salvini, the latter being very much less convex and 
more evenly rounded; in L. chiriquense the greatest convexity of the elytra is at the. 
base, the entire posterior portion being strongly.deflexed. The head.is finely and 
closely punctured, and has an obscure short central groove; the epistome is continuous 
with the front, its anterior margin being moderately emarginate (in L. salvini the 
angles are prolonged into points); the antenne are short, black, the underside of the 
first joint, and the second one entirely, fulvous, the basal joint strongly widened. The 
thorax has its median lobe rather more pointed than in L. salvini, and also has two 
rather distinct depressions at the base in the middle; it is as finely punctured as the 
head, except near the base, where the punctures are, as usual, stronger. ‘The elytra 
are punctured as in L. salvini. The prosternum is smooth, narrowed posteriorly, and 
excavate at its anterior portion. 
36 (Bs). Lamprosoma opacicolle. 
Ovate, scarcely narrowed posteriorly, black; the head and the legs reddish-cupreous, the thorax greenish-blue, 
and the elytra dark plumbeous, the sides of the thorax and the apex of the elytra reddish-cupreous ; thorax 
opaque, impunctate; elytra strongly punctate-striate ; prosternum scarcely broader than long. 
Length 1 line. . 
Head very finely granulate, with a few scarcely perceptible punctures ; labrum and mandibles black; antenna 
scarcely extending to half the length of the thorax, black, the first joint cupreous ; thorax extremely 
finely granulate, opaque, of a dull greenish-blue colour, the sides, but more narrowly so at the base, 
reddish-cupreous; elytra of a bluish-plumbeous colour, more shining than the thorax, very strongly 
punctured, the interstices slightly rugose and with a few fine punctures, the sides with a metallic cupreous 
band extending from below the middle to the apex; the underside and tarsi black ; ‘Prosteraum slightly 
broader than long, with a few fine punctures and hairs.
