Show 198 MR. M. JACOBY ON N E W [Feb. 17, closely placed. Lamprosoma cupreatum, Baly, is of double the size and quite differently punctured, also less narrowed behind. Nearly a dozen specimens were obtained. LAMPROSOMA CUPREATUM, Baly. Nearly all the specimens in this collection which I refer to Mr. Balv's species are smaller, more attenuated behind, and varying in the'degree of their punctuation and colour. In the absence of other characters I have refrained from describing them as new, and believe that they only represent a local variety. Genu3 CHLAMYS, Knoch. CHLAMYS JAPONICA, n. sp. (Plate XI. fig. 5.) Subquadrate-ovate, obscure piceous; head more or less fulvous ; thorax with a posterior elevation, closely punctured and covered with fulvous tubercles ; elytra strongly punctured, with a strongly raised oblique ridge from the middle of the base to the suture, and divided by other transverse irregular ridges; legs obscure fulvous. Length l|-lf line. Head closely rugose-punctate, rather flattened, light or darker fulvous. Antenna? of the same colour, the fifth and following joints transversely widened, third and fourth joints of equal length. Thorax with the middle portion gradually raised posteriorly in a moderate but distinct gibbosity, the apex of which is slightly longitudinally depressed, and the sides obliquely and rather deeply grooved or constricted; the swollen portion of the thorax, as well as the more flattened sides, are covered with irregular flavous or fulvous tuberosities, the interstices of which are closely punctured. Scutellum greatly transversely dilated posteriorly, the lateral angles acute and produced, and its posterior margin concave. Elytra slightly narrowed towards the apex, the sides rather strongly constricted at the middle ; surface covered with deeper and much larger punctuation than that of the thorax ; when viewed sideways the following longitudinal ridges are seen :-a narrow one from the middle of the base runs in an oblique direction towards the suture near the apex ; the anterior portion of this ridge is narrow and acute to the middle, where it is intersected by a transverse ridge which runs from the shoulder to the suture ; the portion of the ridge from the middle to the place where it touches the suture is broader and verv stronglv raised, whicli makes the space enclosed by it appear as being excavated ; near the apex three more strongly raised tubercles placed triangularly are seen ; a short transverse ridge is further visible at the sides within the constricted space ; the suture itself is distinctly denticulate through its entire length. Pygidium closely punctured, with three obsolete longitudinal costae. Kiga, Fukushima. The raised parts of the thorax and the elytra in this species are frequently of a flavous or fulvous colour, which sometimes is that of the entire head and thorax. The species is closely allied to C. |
