EXEMA.—LAMPROSOMA. 173 - 
smooth. The pygidium has a central ridge and two less distinct short lateral ridges. 
The insect is of a shining black colour, the labrum alone being fulvous or piceous. 
Three specimens. 
POROPLEURA (p. 90). 
Poropleura bacca (p. 90). 
To the locality Mexico, add:—Rincon in Guerrero 2800 feet (H. H. Smith). 
A specimen since received from the above locality proves the correctness of the 
Mexican habitat of this species. _ 
LAMPROSOMA (p. 90). 
Lamprosoma nicaraguense (p. 91). 
To the localities given, add:—Muxtco, Teapa in Tabasco (H. H. Smith), Almolonga 
(Hoge). 
Mexican specimens are of a bright metallic green colour, and differ from those from 
Guatemala and Nicaragua in the shape of the golden-cupreous band of the thorax, this 
band, instead of being confined to the sides only, extending very narrowly along the 
anterior margin. L. nicaraguense may also be known by the underside being entirely 
bright reddish-golden. ; 
Lamprosoma sallzi (p. 91). 
To the Mexican locality given, add :—Ventanas in Durango, Acapulco in Guerrero 
(Hoge). 
‘This species greatly resembles the Mexican form of L. nicaraguense; but may be 
known from it by the thorax being almost impunctate, and with the aureous colour 
more extended, and by the abdomen being nearly black. The specimens from Acapulco 
are somewhat smaller and of a more leaden-blue colour, and they have the aureous 
lateral markings of the thorax not so broad and more obliquely shaped ; it is probable, 
however, that this is only due to local variation. | 
2 (a). Lamprosoma bugabense. 
Above leaden-blue, the head, sides of the thorax, apex of the elytra, and the underside and legs golden-reddish- 
 eupreous; thorax strongly transverse, finely punctured; elytra finely punctate-striate, the interstices 
minutely aciculate. 
Length 22 lines. 
Hab. Panama, Bugaba in Chiriqui (Champion). 
This species is so closely allied to L. nicaraguense and L. sallei, that it is only 
necessary to point out the differences: the colour of the upper surface is leaden-blue 
(in one specimen the elytra are duller than in the other) ; the head is minutely and
