Vitalis de Salvaza, in his last consignment to the British Museum, has included the beautiful genus and species here described, and the number of known species from this rich district must now be recognized as 76. Ayuthia, gen. nov. Head including eyes narrower than base of mesonotum, almost the length of pronotum ; front obliquely depressed ; ocelli considerably farther removed from eyes than from each ether, and their interspace strongly, broadly, longitudinally foveate ; pronotum distinctly shorter than mesonotum, late-rally moderately convexly ampliated where the extreme margin is coarsely serrated, the posterior marginal area moderately broad and at the lateral angles angularly truncate ; abdomen in male longer than space between apex of head and base of cruciform elevation, the dorsal surface moderately oblique on each side ; tympanal orifices concealed ,; meta-sternum elevated ; opercula in male short and broad, ex-tending beyond base of metasternum ; anterior femora strongly spined beneath ; rostrum reaching base of metasternum ; tegmina and wings semiopaque, tegmina with eight apical aieas. Allied to losena, A. & S. Ayuthia speclalnle, sp. n. J 1 . Head and pronotum black, moderately palely pilose ; head with the eyes, ocelli, and intra-ocular suffusions, narrow anterior and broader posterior margins of pronotum castaneous, the latter with three prominent black spots ; mesonotum castaneous, with two large central obconical spots at anterior margin, followed by a longer, but more imperfect spot on each lateral area, a central fasciate line, the anterior angles of the cruciform elevation and two spots in front of same, pale castaneous ; body above black ; body beneath castaneous with black suffusions ; face castaneous, with the apical area black.; tegmina with nearly basal half opaque creamy-white,
