been inflicting considerable damage to the young sowings of chil 

 and bamboos, in the Kangra Division. 



The insects belong to two distinct species of Acrididse^ namely, 

 Tryxalis turrita, Linn., and Oxya velox, Burm.. They have been 

 previously recorded in the pages of these Notes as the species 

 amongst other Acridid% in connection with the damage done to 

 crop by so-called locusts in Ganjam both in the year i8go and 1891. 



10. Bamboo Coccid, — Planchonia sp. — Some blighted bamboo 

 leaves were received in June 1898 from Mr. D. Hooper, Curator of 

 Economic Museum, who wrote :— * 



" While exploring in North Bengal I was shown a clump of bamboos that 

 were dying. I examined these and could find no fungus on them, but a minute 

 insect was seen on the leavesi As this may be the cause of death, I send a 

 tube to you in order to see if the insect can be recognised and, if possible, said 

 whether or not it could be the cause of the destruction." 



The insects proved to be a Coccid, and new to the Museum 

 collection, Mr. W. M. Maskell to whom specimens were submitted 

 for examination, replied ; — 



" Your insect on bamboo in Northern Bengal is clearly a Plan- 

 chonia : and is probably P. solenophoroides. Green, MS. But I must 

 wait for Mr. Green's published description before I can definitely 

 give you the species, 



'* I think you may be sure of i]\Q genera at least of the insect. "

 PREVIOUS YEARS, etc. 



I. Specimens of a red-ant sent to the Indian Museum by Mr. A. E. 

 Lourie, of the Forest Department, as infesting a house in Coorg. 

 These have been determined by Dr. Forel as belonging to the species 

 Dorylus fulvuSj Westw. var., labiatus, Shuck. 



2. In the case of a mite found infesting flour in one of the Calcutta 

 Bazars, Mr. A. Michael wrote : — 



" This appears to be our common cheese mite, Tyroglyphus stro, 

 which is quite as abundant in flour as in cheese, the specimens which 

 you send are rather smaller than the English specimens, but I do 

 not rely much on size, and moreover, contrary to what might be ex- 

 pected, where a species of Acarus is common to both temperate and
