which the species surya, Moore, and prabha, Moore, were founded. I have 

 failed completely. L. arcuata from Ceylon I have not seen. There seems to 

 be no doubt, as de Niceville surmised, that all the Indian insects represent 

 only one inconstant species. 

 Deudorix epijarbas. Moore. 



An aberrant specimen from Shillong has all the f asciee on the underside 

 of both wings placed on a white ground. 

 Papilio mayo. Atkinson. 



A very distinct variety from the type of the male is to be found. In 

 this the internervular streaks on the upperside of the forewing and the red 

 basal patch on the underside of the same wing are completely absent ; and 

 the red basal patch on the underside of the hindwing is very much 

 reduced. The most striking variation is, however, the absence, on the 

 underside of the hindwing, of the red subterminal ocelli in interspaces 1 

 and 2 and the red scaling on the disc. In place of the latter there is a 

 very prominent set of pure blue lunular markings, set on a deep blue black 

 ground, and extending in a curve from the costa to the dorsum. Of five 

 males received from the Andamans, three were of this type, the other two 

 being normal. 



Col. Bingham was slightly in error when he stated that the cilia of the 



forewing were black throughout. They are touched with white between 



the veins, though not nearly so conspicuously as in the hindwing — in fact, 



the white cilia cannot be seen at all, unless the wing is looked at edgewise. 



Papilio axion. Felder. 



Bingham places all the North-East India and Andaman insects under 

 axion ; but the forms from the two localities are clearly distinct. His des- 

 cription of axion applies properly only to specimens from the Andaman 

 Islands ; insects from Sikkim and Assam (where the species is very common) 

 are, as a rule, rather smaller and differ somewhat in f acies. The discal 

 pale green band is, in the N. E. form, always narrower and less compact, 

 and very irregular exteriorly ; and there are always present, along veins 

 6 and 7 on the upperside of the hindwing, one or two pale linear streaks 

 interior to the submarginal row of spots, which are not present in any of the 

 Andaman insects I have seen, either in my own collection or in the 

 long series in the Indian Museum collections. On the underside of the 

 hindwing, the pearly sub-basal streak from the costa is always extended 

 evenly to coalesce with the discal band in typical axion this streak is some- 

 what irregular, macular and invariably well separated from the discal band ; 

 the crimson markings beyond the discal band are small and variously 

 shaped — in axion they are fairly large and regularly quadrate ; the 

 black discal spots are also very small and placed on the red markings, and 

 never completely fill up the base of the interspaces, separating the red
