Moth destructive to the Cotton Crops in India. 285 



Dcpressaria Gossypiella, m'tli't. 



Dark fuscous brown, the head and thorax somewhat h'ghter in 

 colour. Anterior wings with an undefined round blackish spot 

 on the disc a little above the centre, and a fascia of the same 

 colour crossing the wings a little above the apex, which itself is 

 black. Under wings of a silvery grey, darker towards the hinder 

 margin. Legs and tarsi black-brown, with the joints light. 

 Length 4-10 inch. 



The larva in the dried state is about 4-lOths of an inch long, 

 largest just behind the head, of a dull red colour, with the head 

 dark brown. 



Li the foregoing extract from Dr. Barn's letter it is interesting 

 to remark, that the cotton grown from American seed is attacked 

 in preference to any other, and that the cotton pluit when grown 

 upon "black soil" remains free from injury. The former fact 

 may be accounted for by the American cotton being of a different 

 species to that usually grown in Lidia, and probably offers seeds 

 which are more suitable to the development of the larva. The 

 latter fact, however, I cannot account for, but it is of much 

 interest, and I trust Dr. Barn will throw some light hereafter on 

 the subject. Wliere there is disease, it is natural to look for a 

 remedy, and if any member present could suggest one in the pre- 

 sent case, which is likely to be effectual, I should feel much 

 obliged. The case is evidently attended with much difficulty, but 

 could any plan be hit upon to destroy the moths before the eggs 

 are laid, a cure might be effected, but how to manage this on a 

 large scale I must leave to more practical Entomologists, seeing 

 no remedy which would be within the means of the cultivator.
