Not until very careful breeding experiments have been carried 

 out will it be possible to ascertain for certain whether under the 

 above references I have included three * allied but distinct forms, 

 or whether, as I am inclined to think and as I have treated them 

 here, these represent but one extremely variable insect that to a 

 certain extent, irrespective of seasonal influences or environment, 

 ranges in colour from the very dark A. ayathon to the com- 

 paratively pale-coloured A. phryxe. Had the habitat of these 

 three more or less distinguishable varieties or forms been separate 

 and restricted, they could have been treated as fairly well-marked 

 races, but this is not the case, for Mr. Mackinnon, I understand, 

 has taken all three flying together on the same day and on the 

 same spot at Mussoorie. 1 think it quite probable that were the 

 whole region over which agathon or its varieties occur thoroughly 

 searched, one or two, if not more, specimens of each would 

 be found. 



Typical form, A. agaihon, Gray. <$ $. Upperside: black; fore 

 and hind wings with the following white or greenish-white streaks 

 and spots in the discoidal cells and in the interspaces. Fore 

 wing : a broad streak in cell, two more or less confluent streaks 

 obscurely divided by a diffuse blackish line below it in inter- 

 space 1, followed by an upper discal series of five short lines in 

 interspaces 3, 4, 5 and 10, and a subterminal complete series of 

 elongate narrow spots ; both the discal and snbterminal series are 

 curved inwards anteriorly. In most specimens the streaks in 

 interspace 1 and in cell are irro rated with black scales. Hind 

 wing: a broad streak along the dorsum divided by vein la, two 

 narrow long streaks in interspace 1, a much broader elongated 

 oval streak in cell, with another elongate broad streak above it in 

 interspace 7, a discal series of five narrow elongate spots beyond 



* Mr. Moore holds that there are four, not three, distinct "species"; but, 

 even allowing the distinctness of A. agathon, A. caphusa., and A. phryxe, 

 A. ariaca, Moore, is so very close to A. agathon. that in any large series it 

 would be impossible, to separate the former from the latter. "
