I9I7-] F- F. LAIDI.AW : Indian Dragon/lies. 325 



Under Calvert's rubric {loc. cit.) this species should fall into 

 the genus Wahnesia of Forster, This genus cannot stand ; its t5^pe 

 species has not been described. As, moreover, Dr. Ris is not dis- 

 posed to subdivide the genus Argiolestes on our present imperfect 

 knowledge, the present species is best left as before, though it is 

 probabl}^ generically apart from the Australian species. 



No other representative of the ' Legion ' has been recorded 

 within the limits of the Indian Empire ; and S. India and Ceylon 

 are at present, I beheve, the only large tropical continental areas 

 without such representation. 



Legion II. Platycnemis. 

 Diagnostic table for the Indian genera. 



A. Upper side of quadrilateral shorter than lower side by at least one-fifth of 



the length of the latter in the fore-wing, usually by more than this, 

 i. Wing petiolated to the level of Ac. 

 Wing relatively long and narrow ; usually 2 or 3 cells between 

 the quadrilateral and the sub-nodus. 



COEUCCIA, Kirby. 



Type : Coeliccia memhranipes (Ramb.). 

 Distribution : Himalaya, Formosa, Malaya, 

 ii. Wing ceasing to be petiolated before the level of Ac. 

 Wing' relatively long and narrow, 4 cells between the quadri- 

 lateral and sub-nodus. Reticulation very dense (over 300 cells 

 on the hinder-wing-). 



/XDOCXEMIS, n. gen. 



Type : Indocnemis kempi, n. sp. 

 Distribution : Assam, ? W. China. 



Wing '2 relatively broad and rounded, 3 cells between the quadri- 

 lateral and sub-nodus. Reticulation on the fore-wing not so 

 dense (not more than 250 cells on the hinder-wing). 



Calicxemis, Selys. 

 Type : Calicnemis eximia, Selys. 

 Distribution : Himalaya, Burma, Tonkin. 



B. Upper and lower sides of quadrilateral nearly equal. 



Third joint of antennae equal in length to second joint. 



COPERA, Kirby. 



Type: Copera margiiitpes (Ramh.). 

 Distribution : Oriental Region, Madagascar. 



It may be added that the larvae of A (probably) inhabit quick 

 running streams, of B, so far as is known, slow moving or still 

 water. 



Genus Indocnemis, nov. 



The genus is to some extent intermediate between Coeliccia 

 and Calicnemis, and probably more primitive than either. 



' Indocnemis, hind-wing length to breadth, 68 : 12. 



■^ Calicnemis, hind-wing length to breadth, 57 : 12 (in C. pitlvenilans).
