to the Gold Coast, and that Southwards its range had passed from Cape Gardafui 

 through the interior to the Nyanza, and thence, still avoiding the coast, had continued 

 downwards to the Orange River. In Asia L. chri/sijiptis occurs commonly, but is 

 not accompanied by L. Alcijjpus. On the other hand, a very similar form, L. Alcip- 

 poides, has been described as occurring in India, of which the authors of Butt. Ind. 

 say, " Its appearance is so erratic over a large extent of country that in distribution 

 as well as in inconstancy of the extent of white, the idea of its being only a casual 

 variety of L. chrysippus is suggested;" and looking to this fact, together with the 

 paucity of specimens taken, their co-existence with abundance of L. chnjsippiis, and 

 the probability that an ancestral form would sometimes occur where the entire 

 difference was one of colour, I should have no hesitation in regarding L. Alcippoides 

 as a case of reversion. On the other hand, I believe that the tetramorphic type found 

 at Aden represents L. chrysippus in its ancestral character, probably preserved 

 through the immigration from time to time of the Afi'ican forms which occur on 

 the Somali Coast." 



Major Yerbury, in his Notes, says, " I have taken L. dorippus and L. chrysijjpus 

 in coitu so often that I have given up catching them as a curiosity. I have raised 

 caterpillars; there seemed no difference between the caterpillars which turned to 

 chrysippus and those that turned to dorippus. The chrysalids were of two colours, 

 green with gold spots, and light waxy purple with gold spots." 



Some of these intermarried specimens are noted in Mr. Butler's paper (P. Z. S. 

 1884, 480) as follows: — "Typical female. Chrysippus taken in coitu at Aden, 

 February 26th, 1883, with Indo- African type {L. Klugii); a typical female L. Dorippus 

 taken in coitu with Indo-African type, Aden, February 29th ; a male of the Indo- 

 African type {L. Klugii) taken in coitu at Aden, February 26th, with typical L. Chrysip- 

 pus, and a male of the Indo-African type taken in coitu at Aden, February 29th, with 

 typical L. Doripjms." 



Parasites of L. Chrysippus. — King (SymboHcge Physics, pi. 37, fig. 9) describes 

 and figures, a species of Chalcis (C. albicrus), as being parasitic on L. Chrysippus.
