Show 130 MR. A. G. BUTLER ON [Feb. 16, on one side is concealed and on the other broken, the latter is of the same sex ; it has the last joint of the palpi much more slender and of nearly twice the length of that of D. fenestrina. When it is proved beyond question, by careful breeding, that dissimilar forms are varieties of one and the same species, the sooner they are put together the better ; but this guesswork, especially when concealed under the guise of an authoritative declaration, is a positive hindrance to the acquirement of accurate knowledge. In many cases where Mr. Meyrick has stated his conviction that a long series of described forms belong to one variable species, he has been subsequently obliged to alter his opinion ; surely he cannot claim that his first action advanced science, since he must know of a truth that it only retarded it. DURDARA ROBUSTA. Durdara robusta, Warren, in litt. The type of Mr. Warren's unpublished description is from Sarawak; it is just possible that Walker may have described it as an Anisodes or a Capnodes in his Supplement, or in one of the papers published in the Linnean Journal; but I cannot venture to attempt its identification. PHARAMBARA VINOSA, n. sp. (Plate VI. fig. 8.) Pale vinous-brown; wings reticulated with darker brown: primaries crossed by six imperfect darker bands, the outer edges of which, and the inner edge of the third one, are defined by blackish lines; the fourth and fifth lines are inarched towards the costa ; the sixth, which is submarginal, is abbreviated and cuts off the apical half of the external border ; on the secondaries there are about three black-edged, ill-defined, abbreviated bands from the costa, the central one is acutely elbowed and bounded on each side near the centre of the wing by a hyaline, subquadrate, white spot; on the under surface all the markings are more sharply defined, and on the primaries is a subcostal, basal, shining, pearly tuft covering the base of the frenulum. Expanse of wings 26 millim. A single male example. The species does not appear to be very closely allied to any named form. U R A P T E R Y G I D ^ E. S Y N G O N O R T H U S , n. gen. Allied to Gonorthus : of the same form and with similar neuration ; but the nfale antennae much shorter and with very short fine ciliations instead of being strongly pectinated. SYNGONORTHUS SUBPUNCTATUS, n. sp. (Plate VI. fig. 9.) Pale creamy stramineous, slightly sericeous; the wings irrorated with greyish argillaceous; the primaries crossed by two nearly parallel, straight, transverse stripes of the same colour ; outer margin and fringe forming a third stripe rather more ferruginous in tint |
