When describing the female of this species Wallace 

 commented upon its differences from M. Lucas's description 

 and figure, and indeed admitted that the latter was " hardly 

 recognizable" as the same insect. As subsequently evidenced 

 by Herrich-Schaffer's second figure and by three typical 

 females now in the Museum, the illustration criticized by 

 Wallace was an accurate one, and therefore not the same 

 insect as the female figured by himself from New Caledonia. 



Group 3. Saletaka, Dist. 



The species all have acutely triangular wings with tolerably 

 regular external blackish borders and a good deal of yellow 

 of various shades on the under surface ; the females vary a 

 good deal in the colouring of the upper surface, the differences 

 being probably seasonal ; there seems, however, very little 

 to distinguish the supposed seasonal phases of the males 

 excepting in 8. mgerrima. 



This group was erected into a genus on the ground that in 

 some of the species the males show an extremely short 

 terminal furcation of the third subcostal branch. This 

 character, however, is not. only valueless for generic, but for 

 specific differentiation, inasmuch as males of the Malayan 

 representative of S. panda sometimes have it well marked 

 and sometimes show no trace of it, proving clearly its unstable, 

 individual, and therefore utterly unreliable nature. As a 

 group, however, it is a natural one, but characters have yet 

 to be discovered which will warrant its being called a distinct 

 genus.
