HUPHINA. 187 



underside it can be recognized at once, as the suft'usion of yellow 

 on both fore and hind wings is restricted just as it is in the d ; 

 the apex of the fore wing, however, is also tinged with yellow. 

 Antennae, head, thorax and abdomen as in the d 1 . 



Dry-season brood. d $ Very similar to specimens of the dry- 

 season brood of nerissa, but always smaller. So far as the 

 markings go, both on the upper and under sides, it is so similar 

 that size alone is the criterion. 



Exp. d $ 52-63 mm. (2-02-2-48"). 



Hab. Recorded, so far as I know, only from Burma. 



Race lichenosa, Moore. d . Upperside : white. Fore wing : 

 basal half of costal margin tinged with greenish yellow and 

 irro rated sparsely with black scales ; apical third of the wing 

 obliquely from the costa to the tornal angle jet-black, the inner 

 margin of this irregular and more or less sinuous ; an obscure 

 whitish subterminal spot on the black area in interspace 3 ; vein 4 

 and the lower discocellular sometimes slightly marked with black 

 scales, the rest of the veins on the basal two-thirds of the wings 

 more or less of the same tint as the ground-colour. Hind wing : 

 terminal margin anteriorly black, the terminal portion of the 

 anterior veins very finely black. Underside : white. Fore wing : 

 the costal margin very broadly and the apex suffused with greenish 

 yellow ; median vein on the inner side broadly bordered with 

 dusky-black, continued along the basal half of vein 4 and then 

 transversely downwards as a black band, diffuse below vein 3. 

 Hind wing : so densely suffused with greenish yellow as to leave 

 only obscure elongate spots of the ground-colour apparent in the 

 anterior interspaces ; the whole surface of the wing more or less 

 closely irrorated with black scales. Antennae black, speckled with 

 white on their inner side ; head and thorax with long greenish 

 hairs ; abdomen greenish white ; beneath : the palpi and abdomen 

 white, the long hairs on the former tipped with black ; thorax 

 greenish yellow. $ . Similar to the d both on the upper and 

 under sides, but darker owing to the broad dusky-black border to the 

 veins on both the upper and under sides. Antenna?, head, thorax 

 and abdomen as in the d 



Exp. d $ 60-70 mm. (2-35-2-78"). 



Hab. Andamans. 



Leaving lichenosa out as a fairly well marked and distinct insular 

 race, very constant in its markings, H. nerissa and its varieties are 

 most puzzling forms. I have examined the genitalia of typical 

 males of nerissa, pliryne and dapha, and they seem to be identical. 

 I am not certain, however, whether the test of identity in the 

 shape and structure of the male genitalia is an entirely reliable 

 one. Provisionally I have placed pliryne and daplia as varieties 01 

 nerissa, till careful breeding experiments can determine whether 

 the above three are mere varieties, one of the other, or distinc 

 forms, for their distribution is peculiar. H. phryne, for instance
