 Descriptions of some new Species from India. By GILBERT 

 J. Arrow. 



Although the Madagascan species are now excluded from 

 the genus Oniticellus, its geographical distribution is still 

 peculiar and many of the species are very abundant and 

 wide-ranging. This is the case with several of the European 

 species, whose correct nomenclature is in some disorder owing 

 to the imperfect knowledge of their distribution and of the
