226 Mr. H. Eltringham's Monograph of the 



Between the nervules are elongated triangular orange ochreous 

 markings, their bases occupying the whole internervular space 

 at margin and their sides outlined with black. H.-w. like that 

 of ^ except for the marginal border. This is rather broader 

 as far as nervule 5, where it becomes still wider nearly reaching 

 end of cell. From 5 to the inner margin its inner edge is not 

 straight but convex. The nervules on the border are blackish. 

 The triangular marginal spots are large, whitish, and edged 

 with black. This black edging is produced inwardly in a 

 double internervular ray, and all the internervular spaces- 

 beyond the marginal spots are dusted with brown. 



$ , f . 4, Ground-colour much duller than in ^ and apical 

 patch yellowish. The h.-w. marginal border on the upperside 

 is almost double the width of that in the ^ , and there is rather 

 more basal black. A broad yellowish suffusion about the inner 

 margin, and yellowish marginal spots. Underside of h.-w. like 

 that in cabiroides but marginal border still wider, reaching the 

 cell and only very little narrower towards apex. 



In addition to the above forms many intermediates 

 occur. An interesting example now before me is perfectly 

 intermediate between tcnelloides and cabiroides, having the 

 pale areas of the upperside nearly as yellow as in the 

 former, whilst the h.-w. underside exhibits a similar 

 pattern, but somewhat less developed than m the latter. 



A. bonasia banka, subsp. 



This, the Abyssinian subspecies, is distinguished by having, 

 rather more black on the upperside, and the inner marginal 

 basal black of the f.-w. is slightly produced upwards so as to 

 touch nervule 2. The dark areas of the underside are quite 

 black, and in the h.-w. the subbasal spots are large and 

 coalescent, forming an almost continuous black band. 



Forms intermediate between bonasia and alicia are 

 rare, but a $ example from Toro now before me has the 

 f.-w. inner marginal basal black slightly produced upwards 

 though not quite reaching nervule 2. 



$^ from the Kikuyu Escarpment generally have the 

 h.-w. yellow on the upperside, with the usual black mark- 

 ings. In a note on the species (P. Z. S., p. 922, 1900), 

 Butler states, quoting from a letter from Mr. Crawshay, 

 that the insect "does not succumb to 90 per cent, cyanide 

 in an hour — cyanide which suffocates every other Lepi- 

 dopteron in twenty-five to thirty seconds." It is to be
