    SO far as the 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 epis borne, 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. See also Selys, Ann. Mus. Gen.

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 Coenagrions that are at all abundant. ^Onychargia atrocyana Selys.
