The present paper brings the number of species to seventy-four and that of the genera to forty-three. Lachnus titabarensis nov. spec. Apterous viviparous female. — Body pyriform, about 2.4 to 2.6 mm long, with about 1.3 to 1.5 mm as maximum width.

Some changes had to be effected in the systematic arrangement, so that at present six genera (old and new) are recognised in the group, together including five subgenera. In spite of repeated attempts not all the species so far described could be examined, accordingly in a final chapter notes are added on the species that were not available. The project for carrying out research work on Aphididae could be realised through the kind help of Mr. D.... |
