Eastern Pier idee, 387 



although It differs so remarkably in structure. I have not seen a 

 specimen. 



8. Piioneris pfnlonome, Boisduval. 

 Picris philonome, Bd. Sp. Gen. p. 453, $. 

 Hab.— Java (Coll. Payen). 



A rare species, allied to P. clemanthe and P. VoUenhovii by the 

 curious hairy red patch at the base of the lower wings beneath. I 

 have not seen a specimen. 



9. Prioneris autothisbe, Hiibner. 



Pieris autothisbe, Hiibn. Samml. Ex. Schmett, ii. tab. cxxiii. ; Bd. 

 Sp. Gen. p. 452 ; Voll. Mon. Pier. p. 20, pi. 3, f. 5, $. 



//a*.— Java (Wall.). (B. M. $.) 



I took this species at 4,000 feet elevation on the mountains of 

 West Java. Vollenhoven has made known the female, which by 

 its black upper wings shows its affinity with P. thestijlis. 



Eronia, Hiibner. 



The Eastern species o^ Eronia form a compact and homogeneous 

 group of very closely allied forms, several of which are hardly 

 more than slight geographical modifications. These insects fre- 

 quent most generally the dry and open forests and plantations. 

 They fly tolerably quickly, with an undulating movement, and 

 often settle upon flowers. The clear blue tints with which the 

 males are adorned render them striking objects in the forests of 

 the Malay Islands.

 Eronia avatar, Moore, Cat. Lep. E. 1. C. p. 61, pi. ii. a, f. 1, $ . 



Hab.—N. India, Darjeeling (Coll. Wall.). 



Female. — Apex rather more rounded than in the male ; dusky, 

 with the spaces between the nervures whitish, as in E. Valeria and 

 iobcea, but leaving only the nervures and outer margin (enclosing 

 the submarginal row of spots) dusky. Beneath, silvery, with the 

 nervures obscurely dusky, the median nervure and its branches 

 on the upper wing broadly blackish (Coll. Moore). 



This fine species seems to be an extreme development of the 

 Valeria type.
