 By R. Shelford, Oxford. 



The majority of the species described in this paper are con- 

 tained in the Hope collection , Oxford University Museum and 

 unless otherwise stated the type-specimens are deposited in this

 Staudinger and Bang-Haas for the generous donation of 

 several new species, most of which are now described. 



Sub-fam. Eciobiinae.
