NOVITATES ZOOLOGICAE XXV. 1918. 69 



of this I should have agreed with him and included these Bhutan-Sikkim 

 specimens under imperialis ; but there is one point of difference that seems 

 constant, namely, the supra-tornal yeUow patch, both above and below, is 

 larger and extends further into the wing than in any Assam $? I have seen, 

 many amongst which have this patch much reduced and almost absent. I thus 

 recognize 3 subspecies.

Armandia lidderdalii (Atk.). 



Atkinson in describing this very remarkable insect was unaware of the pre- 

 vious description of thaidina by Blanchard, and founded on it the genus Bhti- 

 tanitis. Those genus splitters who go entirely by shape and outline maintain 

 the two genera, but structurally Dr. Jordan could find nothing to warrant the 

 separation. There are two subspecies, one only being \\\ t! e Tring Museum.
