BUTTERFLIES. 119 



Burmah, Malay Peninsula and Sumatran form he calls Danisepa rhada- 

 7nantkus, Fabricius, and places " Papilio " diocletianus, Fabricius, which 

 ■was first used of the two names for this butterfly, as a synonym. I am 

 unable to draw any line of division either between the specimens them- 

 selves (as they gradually grade the one into the other) or geographically 

 between the whitest form of the species from Nepal and the darkest 

 form from Sumatra, so the oldest name is here adopted for the species ; 

 which may, however, to be precise, be known as E. diocletianus, local 

 race ramsayi. 



13. EuPLCEA (Pademma) klugii, Moore. 



A very rare species in Sikhim, occurring only in the Terai and in 

 the low outer valleys. I have recently pointed out (Journ. Asiat. Soc, 

 Bengal, vol. Ixi, pt. 2, page 237, 1892), how excessively variable this 

 species is. Two local races are found and meet in Sikhim, E. kollari, 

 Felder, and the typical form, E. klugii, Moore. The former is but 

 slightly blue-glossed on the upperside, the latter brilliantly so. There 

 is every gradation between the two forms. Colonel Swiuhoe has 

 recently added to the very extensive synonymy of this species by 

 describing a Pademma hamiltoni, var. nov., from the Khasi Hills. 

 This "new variety" is not only an inconstant form of E. klugii, but 

 it is more than that, being an absolute synonym of Pademma rcgalis, 

 Moore. 



14. EuPLCEA (Isamia) eogenhofeki, Felder. 



Very rare, and occurs only in the low outer valleys and in the 

 Terai from April to November. It is found more commonly in Baling 

 and Bhutan. 



15. EuPLCEA (Stictoploea) hareisii, Felder. 



This is another protean species, as I have pointed out recently in 

 the Proceedings Asiat. Soc, Bengal, 1892, page 158. The Sikhim 

 form is fairly constant, and may be known as a local race as E. 

 binotata, Butler. It is by no means common in Sikhim, and is found 

 only in the lowest valleys. 



Subfamily Satyrin^. 



16. Anadebis himachala, Moore. 



Wholly a forest butterfly, occurring only at low elevations rather 

 locally. It is found also in Assam and Upper Burmah. 



17. Mycalesis (Vii-apa) anaxias, Hewitson. 



Not uncommon at low elevations. Seasonal dimorphism occurs 

 in this species, but not to a very marked extent. 



18. Mycalesis (Gareris) sanatana, Moore. 



The dry-season form of this species (true M. sanatana) occurs com- 

 monly in forests at low elevations in the spring, while the wot-season 

 form (if. gopa, Felder) is found in the same places during the
