identical with the male of 0. genoveva, Hew., while the silvery- 

 blue colour reminds one of the three preceding species, but the 

 colour is a much paler silvery-blue, and also the anal angle is 

 produced. The underside is much paler in colour, and the blue 

 in the cell is more pronounced than in any of the species hitherto 

 found. The female of this species is at present unknown.

My description of this species was taken from seven specimens 

 (<? 6, 9 1), all of which had been caught on the wing. Mr. F. 

 Brown has lately discovered larv?e and pupae of this rare species, 

 so that I am now enabled to give a fuller description, especially 

 of the female. 



(J. This sex shows very little variation from the original 

 description. The margins of bred specimens are on the upperside 

 quite black. Among themselves all the bred specimens show no 

 variation except as to size, the average size being about 34 mm., 

 and they vary from 30-36 mm. 



9. As mentioned in my former description the type female is 

 slightly smaller than the average size, and I have specimens 

 varying from 33 to 42 mm. 



Upperside. ForpAving : The central area in bred specimens 

 is a rich yellow (much deeper than the type), and below the apex 

 along the costa is often a variable yellow splash. The end of cell 

 is markedly black. Hindwlng is A^ery variable, hardly two speci- 

 mens being alike in regard to the size and position of the central 

 orange suffusion; this may be merely absent as in the type, or 

 may occupy quite half of the wing; sometimes it only shows in 

 the cell, and often separate from the central spot is a splash of 

 orange below the subcostal nervule. 



Underside. Forewiyrg as in type, but with the blue margins 

 to the spots more prominent. Hindiving with a white line 

 extending from the middle of costa to basal portion of abdominal
