Show 500 MR. A. G. BUTLER ON [Nov. 4, without palpi, which would readily account for its being placed in the Anthophilida, though I fail to see any great similarity of this species to Xanthoptera. H. obacerralis varies not a little in the ground-colouring of its wings, the African specimens being usually (though not always) more luteous towards the base than those from Ceylon. HERMINIID^E. 77. H Y D R I L L O D E S INSIGNIS, sp. n. Basal three fourths of primaries black, terminated by an elbowed white stripe from costa to inner margin; a broad cream-coloured belt across the basal third; external fourth sandy-brown, with two costal apical black quadrate spots, connected with the outer one of which is a >-shaped marking on external border, and below this again three black marginal dots ; fringe cream-coloured ; secondaries leaden-grey. Head and thorax black ; metathoracic tufts and base of abdomen shining whity-brown; second to sixth abdominal segments leaden-grey with whitish posterior edges ; anal tuft sordid testaceous ; under surface yellowish, the upper surface markings almost obliterated. Expanse of wings 21 millim. Aden. Quite distinct in colouring from any species known to me ; it somewhat resembles, both in colour and the general arrangement of its markings, Heterochroma leucographa, Snellen, from Sumatra. ENNYCHIID^E. 78. E N N Y C H I A ARABICA, sp. n. Upper surface deep purplish brown, almost black; primaries with a submarginal cream-coloured stripe, slightly widening and incurved towards the costa; a dentated jet-black marginal stripe produced by the confluence of a series of conical black spots ; fringes of all the wings metallic leaden grey ; palpi and collar below white; legs below, excepting the tarsi, whitish ; wings nearly as above, excepting that the black dentated marginal stripe of the primaries is replaced by a slender black line, and consequently the submarginal stripe is wider. Expanse of wings 15 millim. Aden. Not nearly allied to any known species. ASOPIID^E. 79. D E S M I A AFFLICTALIS, Desmia afflictalis, Guenee, Delt. et Pyral. p. 190, n. 125. Aden. Described from an Abyssinian example ; also found on the western coast of Africa. 80. HYMENIA FASCIALIS. Phalana-Pyralis fascialis, Cramer, Pap. Exot. iv. pi. 398. fig. 0 (1782). Aden. This species seems almost cosmopolitan. I have not seen |
