on comparison proved to heDiatracz saccharalis as doubtfully named 

 by Mr. E. C. Cotes, an insect that commonly bores into sugarcane in 

 India. 



To clear the doubt that has long existed as regards the correct 

 identity of the insect, specimens were submitted to Sir G. F. Hamp- 

 son, who very kindly identified them as belonging to the species Chile 

 simple x> Butl. He describes the species as follows : — 



Male : yellowish brown suffused with fuscous. Fore wing with the 

 costal area rather darkest ; traces of dark specks below middle of cell 

 and at lower angle ; the veins of outer area slightly streaked with 

 fuscous: a marginal series of black specks Hind wing whitish with 

 slight fuscous tinge. 



Female paler : the hind wing white. 



The form partellus has on the fore wing of male a highly curved 

 antemedial series of short fuscous streaks, a slight yellowish patch in 

 end of cell, an oblique series of diffused fuscous streaks from apex to 

 middle of inner margin, and a sub-marginal series of specks ; female 

 with some diffused fuscous from apex round lower angle of cell, or 

 sometimes nearly evenly suffused with fuscous, with a dark fuscous 

 patch beyond cell. 



Hab. Japan ; Chusan ; Formosa ; Punjab ; Karachi. Exp. 22

Helivthis avmigera, Hubn. 



In April 1898, from the Sub-divisional Officer, Naogaon, Were 

 received some samples of ganja plants injured by insects. He 

 wrote : — 



" I have the honour to advise despatch by rail of one wooden box containing 

 ganja plants infested with insects called 'Hirkati,' spider, etc., and affected by 



diseases locally called ' Bhuachatta ' or ' Ambola,' etc I mav 



mention here that ' Bhuachatta ' or * Ambola ' is a sort of disease, which, when 

 appears in plants causes the resinous portion to disappear from the plants and in 

 consequence of which no ganja is produced." 



The samples reported to be suffering from ' Ambola ' or ' Bhua- 

 chatta ' and 'Hirkati' all appeared to be atacked by caterpillars of 

 one species, namely, He Ho this armigera. Hubn., which has previously 

 been recorded as attacking crops such as paddy, hemp, poppy, etc., 

 in almost all parts of the world. Accounts of it may be found in the 

 pages of these Notes.
