LVIII.—Records and Descriptions of Indian Acridide 
(Orthoptera). By B. P. Uvarov, F.E.S., Assistant Ento- 
mologist, Imperial Bureau of Entomology. 
HE present paper is based upon a part of the collection 
of Orthoptera sent long ago by the Agricultural Research 
Institute, Pusa, Bengal, to the late W. F. Kirby, and only 
partially worked out by that specialist while compiling the 
corresponding volume of the ‘Fauna of British India.’ 
T. Bolivar, in his recent publication on the Indian Acrididz™*, 
has already mentioned that this book, which ought to be a 
standard work for the study of the Indian Fauna, contains 
many errors, owing probably to the fact that the manuscript 
was not completed at the time of Kirby’s death. A few of 
these mistakes are obvious even from the descriptions and 
drawings, and they have been corrected by Bolivar in the - 
paper referred to, but the clearing up of many questions 
of systematics and synonymy is quite impossible without 
studying the type-specimens. I should say, even, that the 
serious study of Indian Orthoptera is almost impossible 
anywhere else except in the British Museum, since the 
majority of known Indian species have been described by
