In tlio liindwiug tlie discocclliilars are also very slender, the upper 

 rather loug ; the second bifurcation of the median'vein ia'cppositej the 

 end of the cell. The apex of the forewing is rather rounded, the upper 

 part of the outer margin being strongly rounded. The markings of the 

 tiuderside ai'e annular and exceedingly variable. The sex-mark at the 

 base of the hindwing of the male is a conspicuous tuft of black hairs on 

 a dark ground. The hindwing of the female is less angled outwardly 

 than in Masmga. 



60. PORITIA PnEAATtOA, How. 



Morgui, common. My females have the ochreous'areas small, even 

 less than in Mr. Distant's figure. Mr. de Niceville has one from the 

 Malay Peninsula in which the hindwing is more than half ochreous. 

 The male is very variable, but I have no specimen so green, or with so 

 large and solid a coloured area as in Mr. Distant's figure. There is in 

 all my specimens a triangular dark jjatch below the cell and a macular 

 blue band across the apex. 



61. PoEiTiA nEwiTSONii, Moore, var. tavotana, nov. 



Myitta, Tavoy, common. The males are remarkably vn.riable ; many 

 are vrhoUy indistinguishable from those of phraatica. I have taken 

 every variation from those resembling Mr. Distant's figure of phraatica, 

 to those with an irregular blue area below the cell, wholly separate from 

 a long submedian streak and a solid oblir^ue subapical band. The under- 

 side varies greatly and does not differ from that of phraatica. The 

 female is pale blue over fully a third of the forewing, and has more 

 resemblance to the male than to the northern female with its small blao 

 area. lu the Tavoy form this extends from the cell to the hind margin, 

 projecting in the interno-median space within an eighth of the outer 

 margin ; there is a blue spot in the cell and a variable sabapical band 

 sometimes obsolete. The blue area on the hindwing is variable but 

 usnally considerable. The ochreous discal spot of the forewing is oc- 

 casionally present, though obscure. 



Genus Massaga, nov. 

 I described this genus in 1 886, the typo being M. clorinda, which 

 now turns out to be the male of Poritia pofina, Hewitson. Lately, being 

 dubious of its generic value, I asked Mr. de Niceville to omit it in his 

 " Butterflies of India," which he accordingly did. Subsequent exami- 

 nation and the discovery of the female have reassured me as to its dis- 

 tinctness. 



In the forewing the upper radial originates a little beyond the cell, 

 so that there is no trace of an upper discooellular vein ; the middle dis- 

 coooUular is rather stout and oblique, the lower distinct, sinuous. lu
