150 Records of the Indian Museum. [Vol.. XIX, 



The markedly rectangular character of the venation should be 

 noted. Like Megalestes this Himalayan form, with an allied 

 species, has been recorded by Martin {loc. cit.) from Tonkin.

Recorded by de Selys also from Hainan. I have identified 

 the specimens listed above as L. umhrina, Selys with some mis- 

 givings. The 9 specimen in the collection named by de Selys 

 himself has largely influenced me in so doing ; but unfortunately 

 the specimen is very imperfect. I would point out, however, that 

 there is a considerable resemblance between these specimens and 

 the description of the species L. concinna, Selys {Bull. Acad. Belg. (2) 

 xiii, p. 321 ; 1862), a resemblance to which de Selys has not called 

 attention in his account of L. umbrina. Further, there are speci- 

 mens in the British Museum of a Lestes apparently identical with 

 the examples before me, collected by Everett in the Philippines, 

 which have been labelled L. concinna by Kirby. So that it seems 

 to me at least on the evidence available that the two names may 

 be synonyms. On the other hand Selys' measurements of the hind- 

 wing of his L. concinna show discrepancies, possibly due to a 

 misprint. He gives the length of the hind-wing cf 28-31 mm., 

 of the 9 19-22 mm.; and states that the colour of the pterostigma in 

 the adult male is black, paler at the side and end. The specimen 

 described was from Batavia. All the Indian Museum specimens 

 have the pterostigma yellowish-brown except a very adult and 

 imperfect specimen (? sex) from Waltair in which it is dark brown. 



Unfortunately the accounts of the two species given by Selys 

 are neither of them at all detailed. 



The following description is based on spirit specimens from 

 Nagpur, C.P. : — cfHead: Under surfaces, bases of mandibles, and 

 genae yellowish- white ; the rest of the head and the eyes sandy 

 yellow. In dried specimens the eyes have a dark brown colour. 



Prothorax and synthorax almost uniformly sandj'- yellow, 

 distinctly paler on the ventral surfaces, and in the most mature
