The proper identification of this species has hitherto been much obscured, owing to Walker having erroneously catalogued it as representing an Lidiau species, C. saturata, Walk. (antea, p. 54), and Mr. Atkinson, thus misled, refers to C. ohteda, in his excellent Catalogue, as from Sikkim and Assam.* I am indebted to the kindness of Prof. K.Brandt, of the Kiel Museum, for an examination of a typical specimen of Fabricius's species.

Body variable, either long or very short and convex. Head, including eyes, about equal in width to anterior margin of mesonotum ; ocelli much farther apart from eyes than from each other ; face convex, slightly prominent above. Pronotum with the lateral margins moderately ampliated and sinuated. Anterior femora distinctly spined. Tymj^ana covered ; opercula short and transverse. Tegmina hyaline, with the basal cell longer than broad ; apical areas eight ; interior ulnar area sometimes widened at apex. This genus is allied to Dunduhia and Cosmopsaltria, from both of which it is at once distinguished by the short and transverse opercula. It is also divisable, as pointed out by
ORIENTAL CICADIDJE. 69 Stal, into two distinct sections or subgenera, clistinguisheil principally by the sbape and length of the abdomen.

This is a most variable species, both as regards size and markings. The largest specimen I have yet seen is a female in my o\vn collection from Perak, whose tegmina reach an expansion of 216 millim. In some of the smaller specimens the body is darker, and the markings to same and the spotting of the tegmina very indistinct. There almost seem to be two races of this species, one very much smaller and somewhat less prominently marked than the other.
As I have elsewhere recorded, I captured this fine species myself, not mifrequently, when sojourning in the Malay Peninsula. It often frequented the dining-room, and on holding it between the fingers its striduhition caused a thrill through the nerves of the arm.* *ItisprobablythisspeciesdescribedbyMr.HelmsinBorneo:—"Asrreencreatnre,withtransparentwinpsacouple ofincheslonf;,sentforthpicrciuRsoundswhichmaybolieardamileaway.Itbeginswithastrongtrumpet-note,whichhas beenlikenedtothesharpeningofasteelknifeonagrindstone,butinfinitelymorepenetrating.Thisnoteisveryprolonged, andisfollowedrapidlybyothers,graduallygettingfainter,atlastdyingaway,whenitbeginsanewwiththefirstnote,andso continues,fillingthestillnessofthenightwithitsnoisytrumpeting."—L.V.Helms,'I'iouceringintheFarEast,'p.1-11-2.
