BUTTERFLIES COLLECTED IN THE TAVOY DISTRICT. 125 
the two sexes I caught on Pagaye and Kalataung appear to be the same, 
only the female has the ground colour whitish. It appears strange that I 
should have caught so large a number of two opposite sexes and yet for them 
not to be the opposite sexes of one species. The blue markings on the up- 
perside of the males are very variable, hardly any two specimens being alike. 
The extent and distribution of the blue colouring of the male is said to be the 
same as in P. hewitsoni, Moore, the difference bring that in P. hewitsoni, the 
blue changes to emerald green in some lights; this I find is not the case as I 
have three specimens in which the blue does change to green. The males are 
quite distinct from that sex of P. hewitsont on both surfaces and are easily 
recognisable. 
252. Poritia phalia, Hew. 
This is a rare species and seldom met with. Seven males and four females 
only taken on Pagaye and Kalataung, 600’ to 1,500’, between November and 
February. The males are indistinguishable from the same sex of P. pediada 
on the upper surface, but P. phalia is said to be larger. On the underside 
both are rufous-brown, but P. phalia is said to be of a brighter tint. I must 
have caught well over 20 males of different sizes, so it is difficult to say 
which are pediada and which phalia. On examining the undersides I find 
that the larger specimens are not in every case brighter than the smaller ones 
and they appear gradually to intergrade. The females of P. phalia are yellow 
and those or pediada, brown, on both surfaces, but the shape of the wings 
are much alike. The markings on the undersides of the females are the 
same, the only difference being the colour. 
Iam much inclined to think that these two species are one and the same 
and that the female is dimorphic. The distribution of the markings and 
colouring on the uppersurfaces of the males is very variable and it does not 
seem possible to distinguish between the males of these two species. 
253. Poritia pediada, Hew. 
Several males and afew females taken on Pagaye hill, 600, and on Kala- 
taung, 1,500’, during December and January 1919-20. As noted previously 
I am unable to distinguish between these males and those of P. phalia. The 
females of course are brown and appear to mimic abisara echerius angulata, 
Moore. 
254. Poritia phalena, Hew. 
Of this species I have only been able to secure a pair; the male on Pagaye 
hill, 600’, on 23rd November 1917, and the female on 22nd December 1919, on 
Kalataung, 1,500’. The male on the upperside has the spots lustrous sea-green 
in some lights and blue in others. Theshape and disposition of the markings 
are the same as in P. phalia and P. pediada, but it differs entirely on the un- 
derside in that it has a broad white band crossing both wings, about the 
middle, besides which there are several whitish transverse streaks on the 
forewings and the rufous-brown markings on the hindwings are outlined with 
white. The tuft of long appressed hairs on the pale costal area on the upper- 
side of the hindwings is not peculiar to this species but is also possessed by 
the other two species mentioned above. The female is brown above as in 
that sex of P. pediada, Hew., but on the underside it is rufous, rather paler 
than the male. The broad white fascia on the underside of the male is re- 
placed by a narrow whitish line across the forewings only. The whitish trans- 
verse streaks on forewings and the white edging to the rufous-brown mark- 
ings on the hindwings are wanting. 
255. Zarona jasoda, DeN. 
A rare species of which only three males and four females have been 
caught ; a male at Yeawing in February 1919; two males and two females 
on Pagaye hill, 600’, in December and two females on Kalataung, 1,500’, in 
December 1919.
