Remarks. Examination of the syntype series of Agallia biplagiata Melichar , A. campbelli Distant and A. janaka Distant clearly indicated that they are conspecific. This is a very widely distributed species in south India and Sri Lanka with considerable variation in color. Coloration of male tends to be darker than in female. It was generally collected on grass mixed with dicotyledenous plants. H. biplagiata resembles H. plotina in coloration but differs in having an arrowhead shaped aedeagal tip compared to a simple tip of the aedeagus in H. plotina .
