176 | PHYTOPHAGA.—SUPPLEMENT. 
Lamprosoma bifasciatum (p. 95). 
To the Mexican localities given, add :—Acapulco (Hége). 
Lamprosoma guatemalense (p. 96). 
To the locality given, add :—Muexico, Tapachula in Chiapas (Hége) ; GUATEMALA, 
Teleman in Vera Paz (Champion). 
The single specimen obtained by Herr Hége does not differ materially from those 
from Guatemala. 
18 (a). Lamprosoma dubiosum. 
Broadly rounded, black ; the head and thorax (a spot at the base excepted) reddish-cupreous ; elytra violaceous- 
blue, distinctly punctate-striate, the apex with a common cupreous transverse band. 
Length 14-14 line. 
Hab. Panama, Bugaba, Caldera (Champion). 
Two examples. This insect almost agrees in coloration with L. guatemalense, but 
differs from it in its broadly rounded shape and in the elytra being very obtuse behind. 
The apical portion of the latter in L. guatemalense is also more strongly punctured and 
somewhat rugose; in L. dubiosum it is very finely punctured. The two species are 
smaller than any of the other similarly-coloured allied forms. In one specimen of 
LL. dubiosum the thorax has nearly the entire middle of the disc violaceous-blue; in the 
other this colour is reduced to a small spot at the base. 
20 (a). Lamprosoma femoratum. 
Lamprosoma testudineum, huj. op. p. 97 (partim) (nec Lacord.). 
Black below; above dark violaceous or blue; head finely granulate, the epistome deeply emarginate ; thorax 
finely and remotely punctured ; elytra finely punctate-striate; anterior femora angulate near the base; 
prosternum slightly longer than broad. 
Length 23-3 lines. 
Hab. Mexico, San Andres Tuxtla, Playa Vicente (Sad/é), Almolonga (Hoge). 
Our Mexican specimens of this insect were referred in the earlier portion of this 
work to L. testudinewm ; but a more careful examination has convinced me that they 
are distinct from that species and apparently undescribed. The principal differences 
are the deeply emarginate epistome, the sides of which are prolonged into an acute 
point; the largely developed mandibles; and the enlarged and subangulate anterior 
femora. There is only one species described by Lacordaire (Z. azureum) which has 
similarly-formed femora; L. azwrewm, however, has the thorax and elytra finely granu- 
late. In the present species the colour of the upper surface varies from violet to 
blackish-blue, and the general shape is broad ovate and but slightly narrowed poste- 
riorly. The head alone is minutely granulate and finely punctured, with or without a 
fovea at its lower portion; the antenne are black and have the underside of the first
