Show 196 MR. M. JACOBY ON N E W [Feb. 17 length of the body, black, the third and fourth joints equal, the rest shorter, somewhat trigonately shaped. Thorax scarcely broader than long, the sides before the middle produced in a rounded prominence ; another less strongly marked protuberance is placed close to the posterior margins at the sides ; surface convex at the anterior portion, the latter divided by a short .longitudinal groove ; disk strongly but not very closely punctured and covered with rather long yellow pubescence. Elytra subdepressed anteriorly, nearly parallel, more strongly punctured than the thorax, and pubescent like the latter. Legs black, covered with yellow hairs ; posterior tibae curved. Wada toge (August) ; Fukushima (July). I am somewhat in doubt whether this species is not the normally coloured form of T. bicolor, Kraatz, to which at all events it is very closely allied; the differences consist in the entirely black thorax and abdomen, and perhaps in the less closely rugose-punctate head of the present species. Kraatz drew bis description from a single specimen, which had the posterior margin of the thorax yellow as well as the abdomen ; but as in the five specimens before me I cannot discover any trace of this colour, I must consider the species as specifically distinct. I may further add that the latter is not more robust or broader in shape than P. annulata, which is the case with P. bicolor according to the description, and that the legs in some specimens (probably immature) are obscure fulvous. PEDRILLIA VARIPES, n. sp. Below, the posterior legs, and the antennae (the two basal joints excepted) black; above, the anterior legs, and the tarsi fulvous ; elytra and thorax closely punctured, finely pubescent. Var. Head and thorax black. Length 1| line. Head distinctly but remotely punctured, with a narrow longitudinal smooth central space ; that between the antennae with a deep transverse groove ; two lower joints of the antennae fulvous, the rest black, fourth joint distinctly longer than the third, the following joints short and somewhat triangular-shaped. Thorax nearly as lon°- as broad, the sides produced at or immediately before the middle in a distinct angle, behind which a short but deep transverse groove is placed, only visible from below ; entire surface covered with deep and rather closely placed punctures, sparingly pubescent. Elytra parallel and subcylindrical, punctured and pubescent like the thorax, but of a rather lighter fulvous or testaceous colour ; the space behind the middle is very slightly depressed ; the four posterior legs piceous or black ; anterior ones and the tarsi fulvous. Nikko, June ; Chiuzenzi. Smaller and less robust than P. nigricollis, the thorax more coarsely and more distantly punctured, and the anterior legs as well as all the tarsi fulvous. A single specimen of the variety with black head and thorax is before me, but 1 cannot find any other characters sufficient to separate this form as another species. |
