Show 1878.] MR. J. WOOD-MASON ON NEW MANTIDJE. 583 has a great shining red blotch at the base of each of tbe femora, is the only species of the genus which has any part of the internal face of the fore legs conspicuously coloured1. The lamellar fore margin of the tegmina is toothed2 in both sexes, probably so as to act as a stridulating organ by scraping against the corresponding part of the wings. HIERODULA (RHOMBODERA) PUSTULIFERA, n. sp. (Plate XXXVI. figs. 6, 6 a.) 2 • Allied to H. (B.) major, Sauss., but differing in its stouter and broader pronotum, which is more broadly rounded off in front, in the armature of the anterior crest of the fore coxse, which is furnished with eight hemispheroidal yellow tubercles or callosities, all arising from its inner surface, gradually increasing in size from the proximal to the middle, and then gradually decreasing to the distal end of the joint, and constricted at the base so as closely to resemble the crushing-teeth of certain fossil fishes (Pycnodus). The discoidal nervure of the wings emits four branches. The fore tibiae have eleven teeth on the outer edge and fifteen on the inner. Total length 85 millims.; length of pronotum 29, greatest breadth of pronotum (just behind coxal groove) 12*5, of primitive pronotum at supracoxal dilatation 10, at middle of posterior lobe 6 ; length of tegmina 57, to stigma 21 ; breadth of tegmina 24, of marginal field 8 ; length of stigma 3, breadth of stigma 0*9. Described from two alcoholic specimens. A dried specimen in British Museum obtained at the same time measures total length 80 millims., and has the coxal callosities shrunken or less developed. Hab. One of the islands in Torres Straits. The specimens were obtained by the Rev. M'Farlane. Obs. The lamellar fore margin of the tegmina toothed. HIERODULA (RHOMBODERA) TAPROBANA.

ARCHIMANTIS MONSTROSA, n. sp. (PlateXXXVI. figs. 1,1 a, 1 bi) Mantis monstrosus, Bates, MSS., in coll. Brit. Mus. 2 . Closely allied to A.armata,W.-M., 2 » differing in its greater size, in its proportionally longer tegmina (which are fully equal to the prothorax in length), in the form of the pronotum (which is dilated at the setting-on of the fore legs, so as to be conspicuously 1 These coloured femora serve, in all probability, to allure or fascinate the prey. 2 I first met with this curious structure of the tegmina in the Empusidce, in all of which it occurs in both sexes alike. |
