DtsPH^A LiMBATA Selys. 



Dysphma limbata, Kirby, Cat. Odonata, p. 110. 



Seven males fi'om the Aring River some way above Kwala 

 A ring. Known also from Borneo. 



This species is regarded by Selys as a local race of B. dimidiaia 

 Selys, described from Borneo. In all my specimens the black 

 mark at the base of the fore wing extends just beyond the level 

 of the nodus and its margin is straight, at right angles to the 

 anterior margin of the wing. On the hinder wing the black 

 basal maik reaches halfway between the nodus and pterostigma 

 and its outer margin slopes inwards a little, 



Selys has remarked on the scarcity of the females of this group 

 (Bvill, Ac. Belg. (2) xxxv. p. 487). From my own experience I 

 am sure that this scarcity in collections is not due to their being 

 overlooked by collectors. I can safely say that I never saw a 

 female of this species or of Euphcea impar, whilst the males were 

 at times abundant.

Hhinocypha fenestreUa, Kirby, Cat. Odonata, p. 113; Selys, 

 Ann. Mus. Genov. (2) p. 491 (1891). 



This species, which is closely allied to R. qimdrimacuJata of 

 India and R. spuria of the Khasia Hills, ranges from Biirmah as 

 far south as Penang. It is fairly common on the Kelantan River, 

 and Mr. Evans took some specimens in Patalung. There are two 

 specimens in the British Museum from Province Wellesley, taken 

 by Mr. Ridley. 



Rhinocypha biforata Selys, 



Rhinocypha Inforata, Kirby, Cat, Odonata, p, 113. 



This species occurs rather more abundantly than the last on 

 the Kelantan River, 1 also found it fairly common near the 

 foot of Gunong Inas.
