GROUP 2* 

 Species with " marmorated " wings, under 20 millim. long. 



* It is quite beyond the bounds of possibility to tabulate the very closely 

 allied species in this group. A reference to the figures in Plate V, in con- 

 junction with the descriptions, is necessary. The species are reposifa, Walk., 

 himalayensis, tessellatipennis, robust a, marmoratipennis, quasimarmoratipennis, 

 striatipennis, subtincta, elegans, griseipennis, and nigrotibialis, all Brunetti.
