258 PHYTOPHAGA.—SUPPLEMENT. 
branch extends downwards at its outer end, a narrow stripe along the lateral margin, curving inwards before 
the middle and then extending outwards again, a narrow oblique stripe on the disc before the middle, a 
transverse stripe below the middle, a transverse irregular angulated stripe before the apex, a shorter one 
at the apex itself, and several small spots near the shoulders. 
Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith). 
The markings of the elytra are very sharply defined, delicate, and thin, and of a 
somewhat opalescent or golden tint; they vary greatly, and are in some specimens 
interrupted or asymmetrical, but they generally follow the shape and position described. 
The colour of the legs and of the thorax and the fine elytral punctuation principally 
distinguish E. erratica from several of the allied forms; the different shape of the 
markings and the much finer punctuation separate it from E. mexicana, Jac. Numerous 
examples were obtained by Mr. Smith in Western Mexico. 
DIPHAULACA (p. 263). 
Diphaulaca intermedia (p. 264). 
To the locality given add:—Mexico, Amula, Chilpancingo, R. Papagaio, all in 
Guerrero (H. H. Smith). 
The Mexican specimens differ somewhat from the type, and also vary amongst 
themselves, but they agree in the closely punctate-striate elytra and in the black tarsi ; 
in some examples, however, the antenne and the greater part of the legs are entirely 
black.

Hab. Mzxico, Atoyac in Vera Cruz (H. H. Smith).—Cotomsta }. 
The single specimen obtained by Mr. Smith agrees perfectly with the author’s 
description; it is a species of very bright metallic blue colour, and is principally 
distinguished by the deep fovea between the eyes, and the fulvous colour of the base of 
the four anterior femora. 
LACTICA (p. 270). 
6 (a). Lactica inornata. 
Testaceous, the antenne obscure fuscous ; thorax transverse, the basal sulcus deep, the surface impunctate ; 
elytra microscopically punctured. 
Length 12 line. 
Head with one or two punctures near the eyes, the latter widely separated and broadly emarginate, the frontal 
elevations absent, the clypeus broadly triangular; antenne three-fourths the length of the body, slender, 
entirely pale fuscous, the fourth joint one half longer than the third ; thorax more than twice as broad 
as long, the sides very slightly rounded, and with a narrow reflexed margin, the anterior angles obliquely 
truncate, the surface entirely impunctate, the basal sulcus deep, slightly sinuate in the middle, and
