LAMPROSOMA. Li7 
joint and the second one entirely more or less fulvous; the thorax is very finely and 
rather remotely punctured ; the elytra are finely punctate-striate; and the prosternum 
is rugosely punctured. ‘hese characters are constant in the seven specimens .before 
me. The legs have a bluish gloss in some examples. L. amethystinum, Lac., seems 
to be a closely-allied but distinct species. 
Lamprosoma approximans (p. 97). 
To the Mexican locality given, add:—Ventanas in Durango, Chilpancingo in 
Guerrero (Hoge), Puebla (Sallé). 7 | 
The specimens obtained by Herr Hoge differ from the others in being of a bright 
metallic green colour above; but in the produced shoulders and extremely fine punc- 
tuation they agree with the typical form. 
Lamprosoma amabile (p. 99). 
In a specimen obtained by Mr. Gaumer in Northern Yucatan the thorax is of a 
darker and more leaden hue than the elytra; and the prosternum is scarcely longer 
than broad, rather convex, excavate in front, almost smooth, with a few punctures only 
on the surface. 
Lamprosoma pediculus (p. 101). 
A further examination of the specimens referred by me to this species proves that 
they cannot well be identified with it, if Lacordaire’s description is correct, as the head 
and thorax show a distinct punctuation; our localities for L. pediculus refer to the 
following two species :— 
35 (a). Lamprosoma juvencum. 
Lamprosoma pediculus, huj. op. p. 101 (nec Lacord.). 
Ovate, scarcely narrowed posteriorly, black ; above metallic cupreous ; head minutely granulate and punctured ; 
thorax extremely finely punctured; elytra distinctly punctate-striate, the interstices very minutely 
punctured ; prosternum not longer than broad, finely punctured. 
Length 14 line. 
Hab. Mexico, La Parada, Oaxaca (Sallé), Playa Vicente (Hége). 
L. juvencum agrees in size with L. pediculus, but differs from it in the finely 
granulate and punctured head (the punctures quite distinct when seen under a strong 
lens); the punctuation of the thorax is very minute, and the interstices are not 
granulate but shining; the elytra have their apex broadly rounded, and the surface 
very distinctly punctate-striate, some minute punctures being also visible on the inter- 
stices. Lacordaire says that L. pediculus has a nearly impunctate head and thorax, 
even when examined under a powerful lens.
