388 ON THE DRAGOXFLIES OF THE " SKEAT EXPEDITION." [DeC. 2, 



SO far as tlie male is concerned, in being somewhat larger, in 

 having segments 8-9 of the abdomen blue or brownish blue, and 

 in addition having a black epistome, and no black carina on 

 segment 1. 



It is, however, scarcely advisable to name this supposed new 

 species until definite evidence as to the female of the typical 

 A. nigricans is forthcoming.

Two males and a female of the orange variety from Khota

The rose-colour of the latter only extends to the fifth abdominal 

 segment.

The members of the above genus are the smallest known 

 Odonates. The length of the hind wing of a male of A. incisa 

 is 9 mm. and of the abdomen 16 mm. Both this and the 

 preceding genus [Argiocnemis), as well as the two following, are 

 found, so far as my experience goes, chiefly in cultivated low- 

 lying land near the coast. Certainly I never saw specimens of 

 any of them " up-country," whilst in the big rice-fields about 

 Kelantan and Tringganu they are the only Ccenagrions that are 

 at all abundant.
