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 beneath which the small head can be withdrawn ; the ventral surface is flat.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 Membracidae.
