Conclusion
The above description of the male genitalia of some of the important forms belonging to Amblycera and Ischnocera, infesting Indian birds, shows in some degrees the extent of variation and modification undergone by the biting-lice in their male genital structures. It will also serve to emphasise the importance of the male genitalia in the taxonomic study of Mallophaga of both the above mentioned sub-orders. The study of homologies of the various structures is a difficult task until the development of male genital armature has been followed in important groups. Yet the author believes that for the time being they can be persued along the lines of Ewing who has studied the male genitalia of Anoplura or the sucking-lice.
Another inference which can be derived from the above study of the male genitalia of Amblycera and Ischnocera is that in the Amblycerans the male genital structures are of more generalised type and have gone less modification, whereas in Ischnocera we find that the male genitalia are much specialised along various divergent lines.
