I feel pretty sure that the Pseuderesios here described are 

 not the only new ones that I have lately discovered, but I 

 await further material, which I hope to find before very long. 

 They need a deal of hunting, as their haunts are in shady 

 places and they are most difficult to capture on the wing —

 too high up, but they need much looking for ; they rest on 

 twigs and creepers bare of leaves, but, excepting one or two 

 species, seem to be distinctly uncommon.
