190 W. Dolicrty— r/ie Butlerjiles of Sumla and Sauihawa, Sfc. [No. 2, 



100. ApPIAS* PAULINA, Or. 



Two forms of this very poizzling' group occurred botli in Sumba 

 and in Sambawa. One was all white, with only a slender dark marginal 

 line, resembling A. albina. The other had the hind wing and the apex 

 of the forewing bright ochreous-yellow below, resembling A. lankapura, 

 but without the dark apex. It generally had a black or gray discal 

 spot on the forewing. 



I have dubiously recorded Ajopias lyncida from Sambawa, and from 

 Sumba a female which I supposed to be that of A. (Saletara) nathalia. 



101. NePHBRONIA VALERIA, Or. 



Sumba, Sambawa. The submarginal spots are wholly absent. N'o 

 yellow female was taken. A diffei-ent species is, I think, also found in 

 Sumba. 



margin to the lower angle ; the rest black, its inner border serrate. Hindwing with 

 the black border rather wide and equal. Belo^u, forewing black with four (five in 

 helisama) orange snbapical streaks, the lowest obsolescent j a broad oblique orange- 

 streak borders the disco -cellular veins, the cell and median veins are outlined with 

 pale orange, the rest of the cell irrorated with black scales, the hind-margin broadly 

 whitish. Hindwing orange like the npperside, the red area darker than in belisama 

 and much larger j the inner Innnlar band more continuous, a marginal yellow line 

 (nearly obsolete in belisama), the inner half of the wing, including most o-f the cell, 

 and on the disc from the hind-margin to beyond the middle median vein, densely 

 irrorated with black scales. Expanse 3^ inches. From D. helisama this may be 

 distinguished by the much smaller black area of the upperside of the forewing, and 

 the large orange areas of the underside of the same wing. The male of D. helisama 

 is also usually white, or white tinged with lemon, or yellow with a slight ochreous 

 tinge. From D. nakula, recently described from Java by Mr. H. Grose Smith, I>. 

 aurantia differs in its larger size and rich orange colour. 



This fine butterfly is not uncommon on Mount Arjuno, Eastern Java ; I did not 

 take it below 2,500 feet elevation, and it is found at any rate up to 5000 feet. D. 

 belisama is also common there,, ranging from the low country up to about 3000 feet, 

 so that there is a zone where both are found. When flying together I)-, helisama 

 could always be distinguished by its sm<aller size, East Java specimens being 

 apparently smaller than West Java ones, and under three inches in expanse. On 

 visiting the great volcano of Smeru further east at a diiSerent season, I found 

 helisama common, but did not see aurantia at all. 



At 5000 feet on Arjuno, I took a single faded specimen of a Delias only If inch 

 in expanse. It was white, the outer half dark, the forewing with a subapical bar 

 and a row of five subapical spots. The hindwing had the margin broadly black 

 with five yellow (?) spots in it below only. This species does not resemble anything 

 known to me. 



* This is one of Hiibner's silly genera, grounded on nothing whatever. I use it 

 most unwillingly as the equivalent of Mr. Wallace's Tachi/ris. Mr. Distant includes 

 the species of Huphina (Mr. Wallace's Pieris) under Appias,. for which I ca,u see uo- 

 reason. Catophaga necessarily falls before Appias.
