CHRYSODINA. | 187 
seventh joint and also the apical one obscure fuscous. One specimen is of a violaceous 
colour above, but does not otherwise differ from the rest. 
17. Chrysodina vicina. 
‘Blackish-eneous, above bright metallic green, the basal joints of the antenne fulvous; thorax finely and 
closely punctured; elytra strongly punctate-striate. 
Length 14 line. 
Cylindrical and convex, proportionately short; head distinctly but not closely punctured ; eyes widely distant, 
notched; mandibles robust, piceous; antenne rather short, the lower five joints fulvous (the basal one 
metallic blue above), the others black, the latter transversely widened ; thorax transverse, convex, twice 
as wide at the base as at the apex, the sides but slightly rounded, the surface evenly, closely, and finely 
“punctured; scutellum broader than long, smooth; elytra convex, with an obscure depression, the surface 
with deep, rather strong, and closely-placed rows of punctures, the punctures gradually becoming finer 
towards the apex, the submarginal interstices rather strongly gostate; legs dark bluish-green ; prosternum 
longer than broad. 
Hab. Mexico, Chilpancingo in Guerrero (Hége). 
Very closely allied to, and perhaps only a local variety of, C. hegei, from which it 
differs in the dark blue or greenish legs, and in the finely punctured and more trans- 
versely shaped thorax. In C. hegei the legs are entirely fulvous. 
18. Chrysodina atro-violacea. 
Bluish- or violaceous-black, the lower four or five joints of the antennz fulvous; head opaque; thorax im- 
punctate ; elytra finely punctured, the punctuation becoming almost obsolete towards the apex; legs 
violaceous-black. 
Length 3—1} line.

According to Lefévre, who kindly examined our specimens, this is only a variety of 
his C. levicollis ; but in my opinion it is specifically distinet, The colour of the insect 
is blackish-blue or blackish-violaceous, with the exception of the basal joints of the 
antenne. In C. levicollis the apices of the tibie and the tarsi, as well as the antenne, 
are rufous; in more than twenty specimens obtained of the present insect, the legs 
(including the tarsi) are violaceous-black. In C. atro-violacea the head is entirely opaque, 
with a few scarcely perceptible punctures, the front generally impressed with a more 
or less distinct oblong depression ; the thorax is impunctate (but shows some minute 
punctures in the female); the elytra have the punctuation remote and only visible on 
the anterior half, and the submarginal interstice convex; the legs are coloured like 
the underside. C. atro-violacea differs, therefore, from C. levicollis in the black apical 
joints of the antenne, the violaceous-black colour of the upper and undersides, and in 
the unicolorous legs.
