STEMPFFER excised, the manner of the attachment of the valves is the same as in vininga and the vinculum is similarly prolonged to form a stout saccus. The ends of the valves are obliquely truncate, with a serrate margin. In aura and pandora the uncus is only weakly excised above and the penis is less elongate than in vininga and lamborni. The genus Aslauga belongs to the sub-family Liphyrinae, sharply characterized by the five-segmented male fore tarsus, the morphology of its pupae and its larvae. The early stages of A. vininga and A. lamborni were the subject of the remarkable observations of Dr. Lamborn (1914, Trans, ent. Soc. Lond., 1913 : 446-7) and the pupae of the same species have been described by Eltringham (1922, Trans, ent. Soc. Lond. 1921 : 473, pi. 12, figs 4 and 5) and by Bethune Baker (1924 : 214-7, pis 17 to 24). I give below only a brief summary of these researches. The caterpillars, seen from above, are oblong with the sides sloping downwards and outwards ; the dorsal skin, which is tough and covered with rough tubercles, forms a kind of carapace beneath which the small head can be withdrawn ; the ventral surface is flat. They feed on Coccidae and are cared for by ants of the genus Crematogaster, which erect around the caterpillars small shelters made of particles of bark and other vegetable debris. The carapace enables the caterpillars to withstand any casual attacks from the ants. The chrysalis bears branched hairs of a complex structure ; some are like the flower of a water-lily with a long pistil, others like small balls on a short stem. Eltringham calls these hairs " chitinanths ". The caterpillar of A. purpurascens Holland has been described by T. H. E. Jackson (1937, Trans. R. ent. Soc. Lond., 86 : 207) ; it also has a kind of carapace and feeds on Please note that these images are extracted from scanned page images that may have been digitally enha
