Differs from D. luteola St. in the black scutellum and regular elytral punctation, from D. nigrimana St. in the unspotted thorax, colour of the underside, &c. ; also in the same way from D. obscurimana St. D. jiavida St. has the elytra geminate-punctate. I know only of a single specimen of this species, contained in m y collection without detailed locality. DESMOGRAMMA STALI, sp. nov. Dark fulvous, the thorax with a transverse obscure greenish-aeneous band, remotely punctured; elytra strongly punctate-striate, the third and the ninth interstice, as well as the basal margin, flavous, the other interstices alternately fulvous and greenish aeneous ; underside greenish, legs fulvous. Length 8 millim. Head sparingly punctured, fulvous, the space between the eyes greenish aeneous ; antenna? with the terminal five joints strongly widened, black, the lower seven joints and the apex of the bust one fulvous, third joint very elongate ; thorax more than twice as broad as long, the sides straight, the surface remotely and rather strongly punctured, dark fulvous, with an obscure transverse greenish-aeneous band placed at the anterior margin and not extending to the sides, to this band another spot is joined at the middle and extending to the base ; scutellum flavous ; elytra with regular rows of deep punctures, dark fulvous, the second, fourth, sixth, eighth, and tenth interstice greenish aeneous, the third and ninth as well as the basal margin bright flavous, joined at the apex; below greenish, the margins of the abdominal segments and the legs fulvous, the femora stained with aeneous: claw-joint simple, prosternum raised anteriorly, metasternum truncate. Hab. Brazil. Of this species, quite distinct in its system of coloration from any of its allies, I have a single specimen without detailed locality ; the submarginal flavous stripe is slightly curved at the middle and has a single row of punctures posteriorly; the elytral epipleura? are fulvous.
