I have grouped these specimens in two series, the reason for 

 which action I will explain in the sequel. 



Dealing with series A in the first place. These specimens are 

 all evidently typical examples of L. cyanea. 



Below I give a short account of a male and female from the 



Simla Hills C^) taken in May. 



Pterostigma black, antenodals on front wing 12-13. 



cf Head : Upper lip and anteclypeus with bases of mandibles 

 and genae pale bright blue, othewise dorsal surfaces black. Eyes 

 gray-blue above passing to pale olive colour below. 



Prothorax : Black dorsally, with a small median spot of bright 

 blue, and a pair of lateral spots of the same colour. Ventrall}^ 

 greenish-white. 



Synthorax : The dorsum is bronze-black with violet reflex. 

 The mid-dorsal carina is finely marked with greenish-blue.

There is a narrow ante-humeral band of bright blue, limited 

 externally by the humeral suture, and incomplete above. Later- 

 ally the colour is blue marked with a bronze-black band running 

 upwards obliquely from the anterior half of the mesinfraepis- 

 tenite, bounded anteriorly by the humeral suture. At its summit 

 this band turns backward past the wing bases giving off a fine 

 branch, which descends as a narrow black blue along the second 

 lateral suture. The black band also encloses a small blue mark 

 immediately behind the top of the humeral suture. 



The wing bases themselves are marked with spots of blue; 

 the under surfaces are pale greenish white. 



Abdomen : Segments 16 vivid blue above, paler beneath, and 

 marked with black as follows : — 



Segment i has a transverse basal line dorsally, and a pair of 

 black lateral lines incomplete posteriorly ; separating the bright 

 blue of the dorsum from the paler ventral colouring.
