cence. The antenne have the basal joint blackish, the others fulvous, the second and 
third joints being very small. The labrum is generally fulvous. The thorax. is at least 
twice as broad as long (which separates C. purpurea from C. desmiphora, Lac., in which 
the thorax is stated to be nearly as long as broad); its punctuation is very close and 
fine, while that of the elytra, although as fine, is more rugose in appearance. The 
specimens before me, however, vary in the intensity of the punctuation and also in size ; 
but, judging from examples collected together in the same localities, I believe them to 
represent one and the same species.

Hab. Mexico (Sallé).—Braziu 1. 
A single specimen contained in the Sallé collection agrees very nearly with the 
description of C. guadrillum, a species said to come from Brazil. Most of the species 
of this and the following genus are, however, so closely allied that they can hardly be 
identified for certain without comparison with the type. In the Mexican example 
before me the thorax is obscure eneous, very finely and closely punctured and pubes- 
cent, and about twice as broad as long; the elytra are black, scarcely more strongly 
punctured than the thorax, and have a subquadrate red humeral patch (extending 
inwards to the middle of the base and downwards to a fourth of the elytral length, and 
reaching to the lateral margin); and the antenne, femora, and tibia are fulvous, and 
the tarsi black.

Euryscopa pilatei (p. 32). 
Lacordaire compares this species with #. pulchella, and says that it resembles it 
entirely in form; he, however, describes the thorax of KE. pulchella as “scarcely one 
fourth broader than long,” while in Z. pilatei (and in most other species of Huryscopa) 
the thorax is at least twice as broad as long. It is therefore difficult to account for 
Lacordaire’s statement in his otherwise excellent descriptions; and it is not likely that 
he referred to another species, as all the other particulars agree entirely with Z. pilatet, 
of which correctly-named specimens are also contained in the collection of M. Sallé 
and that of Mr. Baly. 
Euryscopa scapularis (p. 32).

E. scapularis differs principally from H. pilatet in its black and longer thorax. It
