320 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, thigh ; — the whole work of raising the body is thrown disadvan-tageously upon the long muscles of the back of the thigh. The possibility of raising the body on the legs is rather permitted by circumstances generally favourable than brought about by direct means. It is in the comparative shortness and lightness of the head and anterior part of the trunk : the length without undue weakness of the hind limb : above all, as it appears to me, in the imperfect isolation of the several muscles which enables them to act in certain directions with combined strength that we must find an explanation of the power possessed by this lizard of simulating the gait of a cursorial bird ; certain it is that in its muscular system it has no feature relating it to anything higher than its fellow reptiles. Decriptions of Australian Micro-Lepidoptera. By E. Meyrick, B.A. IX. Oecophoridae — (Continued.) The following additional species of Eulechria (besides others) were obtained since my last paper left my hands, and are therefore not included in the analytical table of that genus ; but as they are closely related to the concluding species, they may be added here without disturbing the systematic arrangement. The first alone is of somewhat doubtful affinity ; the second belongs to tiie group of Eul. scopariella ; the remaining four form a single peculiar group, with the forewings more elongate and generally narrower than in any others, except Eul. perdita. 108. Eul. leucophanes, n. sp. Media, alis ant. niveis, nitidis, margine costali basini versus angustissime fusco ; post, dilute albido-fuscis ; thorace griseo. $ 17-20 mm., ? 24 mm.
