assarica, Crm., respectively. We are led to a similar 

 conclusion by receiving a long series of both sexes of two 

 different forms from Biak. The zoilus form is represented 

 by mysoriensis, Stgr., and the assarica form is undeseribed. 



Heer Van Eecke in his report of the Rhopalocera collected 

 by the Third Dutch Expedition, follows Frnhstorfer in 

 treating all the forms as belonging to one species ; he further 

 supposes that the whitest Eorm was the most primitive 

 and that a darkening process has been going on. 



We have examined a large number of specimens, including 

 those in the Tring Museum, and, as far as pattern goes, 

 find three characters which, though not entirely constant, 

 hold good for the majority of specimens representing 

 zoilus, Fbr., and assarica, Crm. These characters may be 

 thus tabulated : — 



ZOILUS. ASSARICA. 



Fore-wing — Fore-wing — 



Apical spots separated. Apical spots joined to form a 



hand. 



No spot below vein .'> or only A spot below vein '.) generally 



a dot. \\i 11 marked. 



Hind- wing below — Iliml-wing below — 



A second basal spot below No basal spot below the 



the median. median or only a few white 



scales. 



In a few specimens bearing the fore-wing characters 

 of assarica we have found a well-marked second basal 

 spot on hind-wing below. A series of 2>s typical assarica 

 from Ceram in the Tring Museum have all only 1 basal 

 spot on hind-wing. The form we now describe also agrees 

 in 1 his respect without exception ; on the other hand, every 

 specimen of the zoilus Eorm received from Biak possesses 

 two basal spots. 



If Tellervo contains two species a proper definition of 

 them has still to be given.
