 I cr' vSilonibari. 



Length of abdomen i8'5 mm. 

 ,, hind-wing 22'5 mm. 



,, pterostigma 3 mm. 



Slightly smaller than the typical race from Ceylon. The basal 

 golden-brown mark on the hind-wing is less extensive also, reach- 

 ing only to one cell beyond the triangle, whilst its outer border is 

 regularly convex, thus differing from the specimen figured by Dr. 

 Ris from Ceylon. 



Examination of a sufficient series will probably prove these 

 specimens to represent a geographical race of the species recog- 

 nizable from that inhabiting Ceylon and southern India.
