15. P. agamemnon L. 



— agamemnon (L.), cT — Sungai Kumbang (Kurintji) ^- 8/1915. 



— lasius subspec. nova, 7 cTc? and 5 99 — Pulu Lasia — 9/1915, 

 When I received anno 1914 one female specimen from Sinabang (Simalur), 

 I saw at a glance, that the specimen was much darker than those from 

 Sumatra and Nias, but I feared to name a subspecies on a single type. As 

 however a dozen specimens from Pulu Lasia seem to be constantly much 

 darker like the subspecies atropictus Fruhst. from Engano, I dare to name 

 a melanistic insular race. Except the brownish black colour and the little 

 submarginal and discal spots of the upperside, the underside shows more 

 distinguishing characters. All the spots, which are yellow in agamemnon 

 from Sumatra and Nias, are white in lasius, except three basal spots in 

 the cell of the forewing and partially the basal striga of the hindwing. 

 The two white spots between the costal, subcostal and upperradial ner- 

 vules are transparent ; the transcellular black spot between the costal and 

 subcostal nervule, which spot borders upon the transparent white one, 

 is largely developed. The prime-colour is very dark redbrown like on 

 the figure of plate VII.
