Show 194 MR. M. JACOBY O N N E W [Feb. 17, Var. b. Elytra and antennae fulvous ; the suture and lateral stripe fuscous ; the costae, with the exception of the fourth indistinct; rest as in Var. a. (Nikko, Miya, Riga.) Var. c. Larger, the elytra more smoothly punctured, without any costae ; testaceous, thorax stained with fuscous. (Nikaido.) From the above localities specimens agreeing with the type in colour and structure were also obtained ; between this and the above varieties some more intermediate stages in colour and sculpture are present, and it will be seen that Mr. Baly drew his descriptions from unicolorous fulvous specimens'; the same' author describes the thorax as transverse, with which some specimens (2) agree ; in the males the thorax is, however, much longer although agreeing in every other respect; but I have no doubt that all belong to one species. The specimens vary in size from 2-4 lines. Genus LEMA, Fabr. L E M A ADAMSI, Baly. A variety of this species, obtained at Yuyama, differs from the typical form in having the elytral spots joined in shape of a longitudinal broad band which occupies nearly the entire disk, leaving only the sutural and lateral margin fulvous ; the tibiae and tarsi are also entirely black ; in other respects there is no difference. I may further remark that the specimens contained in the collection of Mr. Lewis, as well as the variety described here, have the first joint of the antennae fulvous only, not the two first as mentioned by Mr. Baly. LEMA DILECTA, Baly. All the specimens before me, obtained at Ogura Lake and Kioto, have black legs, with the exception of the base of the tibiae, which is fulvous ; in the type the legs are entirely of that colour; but I can find no other differences whatever. Genus CRIOCERIS, Geoffr. C R I O C E R I S LEWISI, n. sp. (Plate XI. fig. 3.) Oblong, parallel, subdepressed, black ; thorax fulvous, impunctate, three spots on the disk and one at each side black; elytra fulvous, deeply punctate-striate; the interstices partially costate, the suture and a longitudinal band on each elytron black. Length 2| lines. Head deeply constricted behind the eyes, with a deep longitudinal groove between the eyes, the latter large and very prominent; orbital grooves distinct, the space between it and the eyes thinly covered with yellow pubescence as well as the lower part of the face. Antennae more than half the length of the body, black ; the three or four lower joints shining, the rest covered with close pubescence, dilated ; the second to the fourth joints gradually elongate. Thorax subquadrate, moderately constricted at the middle, without a basilar groove,fulvous; three elongate spots placed triangularly on the disk and a lon°- narrow |
