The specimen figured is from Sikkim, and has been kindly lent to mo 

 by Mr. Paul Mowis. The left-hand side of the insect is much smaller 

 than the right-hand side, so that at first sight it appears to be 

 a bilateral gynandromorphous specimen ; but on examination closely 

 the forelegs are found to be both masculine, and there is the usual 

 male brand on both forewings in the middle of t!ie submedian inter- 

 space, the brand on the smaller left-hand wing being only 4 mm. 

 in length, while that on the opposite wing is 9 mm. long, or more than 

 twice the length of the other. The number of spots on both pnirs of 

 wings on the upperside is the same, but on the underside the larger 

 forewing has three additional violet spots, one each in the first and second 

 subcostal, and the third in the lower discoidal, intei^paces. On the 

 larger hindwing also there are five additional violet spots, a large 

 apical one in the subcostal interspace, and seven instead of three, 

 placed one in each interspace beyond the discoidal cell. The specimen' 

 is altogether a very remarkable one ; it is not an ordinary aberration 

 or " sport," nor is it gynandromorphous, -so it is difficult to know how 

 to clas-sify it. Owing to the diff'orence in the size of the white markings 

 on the upperside of the forewing, the smaller left-hand wing may be 

 said to be true E. core, while the larger right-hand wing, with its dispro- 

 portionally larger markings, is a typical E. vermiculata, Butler, the latter 

 name applying in the writer's opinion to the dT3'-season form of E. core, 

 true E. core being the wet-season form {vide this Journal, vol xi, 

 p. 214, n. 7(1897).
