160 Dr. A. G. Butler on the 



in ground-colour but with the markings more or less run 

 together into streaks. The D. Horsfieldii form occurs both 

 in India and China, as also does typical D. belladonna. The 

 more or less development of yellow patches on the upper 

 surface of the secondaries is certainly an unreliable character 

 and not of specific value ; otherwise both D. ithiela and 

 D. patrua would have claims to separation. I shall consider 

 this species under its varieties.

Sixty-six specimens in B. M. and coll. Hewitson as 

 follows : 



Var. 1. D. Jlavalba. 



Darjiling. Three in B. M. Three (not labelled) in coll. 

 Hewitson. Two of our specimens from the Godman and 

 Salvin collection. One of Hewitson's examples is almost 

 wholly white above, the white spots running completely 

 together almost to the outer border, and therefore more 

 aberrant than in the following : 



Var. 2. D. lativitta, 



Ta-chien-lu, Moupin, Bernard my o in Burma (Leech). 

 Not in the Museum series at present.
