480 Mr. B. P. Uvarov— Records and CORRODENTIA. Psocus acourti, sp. n. (Fig. 50.) Wing about 3 mm. long, pale grey with fuscous veins ; stigma pale luteous. Fie. 50. Psocus acourti, sp. n. H. 836. Essentially similar to modern species. LVIII. — Records and Descriptions of Indian Acrididae (Orthoptera). By B. P. Uvarov, F.E.S., Assistant Ento-mologist, Imperial Bureau of Entomology. The 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/ I. Bolivar, in his recent publication on the Indian Acrididse *, 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 * " Contribution al conocimento de la fauna Indica. Orthoptera (Locustidse vel Acrididw)," Rev. R. Acad. Cien., Madrid, t. xvi. no. 6, 7, 8, & 9, pp. 278-412.
