captured in Java by Fruhstorfer, but now in my collection, which bears a 

 strong resemblance to the P. (Appias) Nebo from Upper Birmah, figured by 

 Grose Smith (Rhopaloccra exotica III). The yellow ones are not known as 

 living in Java; I saw, however, such a pale yellow c? of Nero from Perak in 

 the collection of Ch. Oberthur, and another one from West Borneo in the 

 Leyden museum. This French lepidopterologist, just mentioned, also presented 

 me with a yellow c? of Zarinda, which for this reason I figure here also. 

 Dr. Hagen mentions a verj' pale orange specimen from Sumatra, which colour 

 may be a transition to this yellow; among the specimens from Borneo the 

 under-side also is always almost yellow already. On the upper-side of the 

 wings of the d a beginning of the tendency to get darker by the increase of 

 the black, is to be noticed in the particularly thick and black indication of the 

 veins in the wings in some specimens, while even some — as Bingham also 

 mentions of the British-Indian ones — show some irroration of black scales near 

 the apex of the wing. But in the 9 whose ground colour on the upper-side 

 is also paler already than that of the d, the black shows itself in a much 

 higher degree ; not only by the extension along the margins and the appearance 

 of the spot in the interspace between veins 2 and 3 on the fore-wings, 

 already spoken of in the Introduction but especially very distinctly by the 

 hooked stripe which so well characterizes the beginning of this increase, and 

 about which I also spoke there, which stripe in this species, it is true, is not 

 strongly hooked, but somewhat rounded, but which can, however, easily be 

 recognized as the same. I also possess a 9 on which this black has still much 

 more increased, so that it resembles much some 9 of the form Zarinda Bsd, 

 the more so, as also the red of the upper-side has already turned into orange. 

 I also give here a figure of it (PI. II, fig. i), because I do not think it impos- 

 sible that it was caught in Java, as I found the specimen in a box which 

 contained only butterflies caught by me in Java. It is true, however, that this 

 specimen bore no special label, so that it may after-all prove to be an error. 

 In that case this specimen is probably from S. E. Borneo. 



The under-side of the 9 is always much paler than the upper-side, this is parti- 

 cularly the case in 9 from Nias (Ramosa Fruhst.) and from Palawan (Pala- 

 wanica Stdgr.) ; in the Zarinda 9 from Celebes the colour-evolution has proceeded 

 much further still. Some of those resemble the 9 of Nero, but with a stronger 

 increase of the black, and the orange having remained still very bright. In 

 others on the contrary the black has already extended over the whole upper- 

 side with the exception of some pale orange spots on the same places, in 

 which there is still a bright orange in the first-mentioned 9, and which therefore 

 are undoubtedly remnants of it. When 9 are still further advanced, this orange
