LuCASii; some specimens are growing much paler and then the colour is 

 really j-ellowish. In the form Leptis this getting paler has proceeded much 

 further, and the under-side of the hind-wings of the d has already got pure 

 white, whereas those of the 9 are a little more yellow whitish {pcJiroIaiats), in 

 some specimens even still a light yellow, and in that case approach the palest 

 specimens of the form Lucasii. On the upper-side the three forms differ only 

 in the already mentioned extension of the black; for the rest they are always 

 white; in the collection Fruhstorfer I, however, saw a ? from the Gedeh 

 mountains in W. J., the upper-side of which was yellowish. 



W. J. I never found this butterfly in lower localities than Tjampea (i6o) 

 and Buitenzorg (265), and then even the butterflies which were caught there, 

 all belonged, if I well remember, to the form Leptis Felder, which seems to 

 form a separate race there; in the higher localities (1400 — 1700) of the Gedeh-, 

 the Salak- and the Wajang mountains on the contrary', only the type and the 

 form Lucasii Wall, were found, the type at least in great numbers. On the 

 mountain-pass (1482) of the Megamendoung, on the frontier between the pro- 

 vince of Batavia and the province of Prajangan, they are generally seen to be 

 sitting on the wet sand drenched with urine. 



A more extensive knowledge of the early stages of these mountain butter- 

 flies than I have been able to obtain, will solve the question whether the 

 form Leptis Felder must be considered to be a race of this species or a 

 distinct species. 



C. J.? 



E. J. Fouspa (630) in the Tengger mountains and in Banjouwangi. 

 Fruhstorfer found the butterfly very common in E. J., also in the form 

 Leptis Felder, but the latter also never higher than at 700 metres. At Tjampea 

 I found the caterpillar of the form Leptis Felder on Taraktogenos Blumei 

 Hassk., it was, however, just going to pupate, and so perhaps the colour had 

 already turned a litde paler. It was smooth, pale yellow-whitish {ockrokucus), 

 with many black spots ; on the skin there were small sharp spines. The pupa 

 had the common Pieris type, pale yellow, also with many black dots. On the 

 head there was a hooked projection bent backward ; on the middle of the back 

 of the thorax there was a transverse yellow ridge of only small height; while 

 on each side of the back of the foremost abdominal segments there were three 

 projections of a yellowish colour like the head-process, but with a black extremity 

 and black margins. 



On the y^ of April the pupation took place and on the 7"' of April the 

 imago emerged from the chrysalis.
