Descriptions of Indian Acrididee. 481 
Walker and the correct location of Walker’s species is 
possible only by studying the types, his descriptions being, 
in most cases, useless. Most authors, therefore, simply 
ignore Walker’s species, which results in multiplying 
synonyms. ‘Thus, the study of the collection now before 
me revealed that many species described by Brunner v. 
Wattenwyll, I. Bolivar, ete., are doubtless synonymous with 
species of Walker’s, and further descriptions of new Indian 
Orthoptera, regardless of Walker’s species, will only add 
to the confusion in nomenclature and synonymy, which is 
already too great in Orthoptera. 
The identification of the part of Pusa collection which 
has not been worked out by Kirby has enabled me to 
describe a number of new forms, the types of which are 
incorporated in the British Museum collection. 
Subfamily Acrrprmwx. 
1. Acrida exaltata, Walker. 
1859. Truvalis exaltata, Walker, Ann. & Mag. Nat. Hist. (8) iv. 
999 
pp. 222. s 
1893. Tryvalis brevicollis, Bolivar, Aun. Soe. Ent. Fr. lxx. p. 588. 
1902. Acrida lugubris, Burr, Trans. Ent. Soc. London, pp. 157, 170. 
W.F. Kirby, in the ‘ Fauna of British India’ (Orthoptera, 
Acridide, 1914, p. 99), correctly synonymized drevicollis, 
Bol., with evaltata, Walk., since the only difference between 
these two species, according to Bolivar himself, is in the 
coloration of the wings. The large series of specimens 
before me shows most clearly that this character is subject 
to individual variability, and it is easy to find all the gradual 
transition-forms between the two extremes; Burr’s species 
has the most infumated wings, while evxaltata, Walk., is 
intermediate between it and brevicollis, Bol., which has the 
wings entirely hyaline. ‘The difference between evaltata, 
Walk., and the South European turrita, L., is also very 
minute, and it is possible that evaltata is but a geographical 
form of ¢turrita. 
This species seems to be very common in India, since the 
Pusa collection contains a large number of specimens from 
different localities. 
2. Acridella nasuta, L. 
Bilaspur, Central Provinces, ii. 1907; Surat, Bombay, 
12. vi. 1904. 
The Indiau specimens are quite typical.
