160 Dr. A. G. Butler on the 
in ground-colour but with the markings more or less run 
together into streaks. The 1). 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. tthiela 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

Var. 1. D. flavalba. 
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, Bernardmyo in Burma (Leech). 
Not in the Museum series at present.
