262 Mr. Martin Jacoby’s List of the Phytophagous 
Disonycha levigata, sp. n. 
‘Fulvous, the antenne (the basal three joints excepted), the apex 
of the tibie, and the tarsi fuscous ; head and thorax impunctate, 
the latter obscurely marked with piceous; elytra bright metallic 
green, microscopically punctured. 
Length, 3 lines. 
Head impunctate, with the exception of some deep punctures 
near the eyes; frontal tubercles scarcely indicated, broad and flat ; 
clypeus rather strongly raised and broad ; labrum black; antennz 
not extending much beyond the base of the elytra, robust, black, 
the lower three joints fulvous beneath, the third joint one-half 
longer than the second and slightly shorter than the fourth, the 
following joints of nearly equal length and subquadrate in shape ; 
thorax twice as broad as long, the sides nearly straight, narrowed 
towards the apex, the anterior angles obliquely thickened, the 
posterior ones strongly oblique, the surface impunctate, with an 
obscure blackish transverse band towards the apex; scutellum 
broad, black ; elytra bright metallic green, with a narrow reflexed 
margin, the surface extremely finely*punctured (when seen under a 
very strong lens) ; underside and the femora fulvous. 
Hab. Grenada—Lake Antoine and Telescope Estates 
(Windward side). 
From those of its congeners with unicolorous metallic 
elytra, the present species may be distinguished by the 
fulvous head, thorax, underside, and femora, in which 
respect it differs from D. mellicollis (Say) and D. collata 
(Fabr.). The insect seems, however, more nearly allied 
(as far as coloration is concerned) to the Central- Ameri- 
can D. mexicana, Jac.; but may be separated from it by 
the black labrum, the bright metallic green elytra, the 
differently sculptured head, and rather large size. Two 
specimens.
