One of the female specimens under study (Lungsen, 11. xi.1976), has a lateral black patch on synthorax, on ferruginous background. The mark is more evident along the humeral suture and around the spiracle but becomes more distinct when the surface Is moistened with benzene. Dr. M.A. Lieftinck kindly confirmed its identity as C. s. servilia (Drury) , so that the presence of such a mark appears to be an individual variation, although not mentioned in the description of this subspecies b y Fraser (1936). It may be noted that the presence of a V-shaped lateral black markon synthorax has been considered as one of the distinguishing characters for Crocothemis indica Sahni ( Sahni, 1965, Lahiri et. al, 1972).

Distribution: Ranging from Mesopotamia to Japan, Philippines, Malaysia and Indonesia.
