and young and full-grown larvae can usually be found at any time, so 

 that the broods are not clearly defined. 



Control is easy. The adult females may be caught as they are ovi- 

 positing, or the positions where eggs have been laid may be seen and the 

 eggs destroyed, or the larvae may be hand-picked. 



The life-history and damage done are shown in a coloured plate

This species is distinct from the Shillong rose sawfly, having a reddish 

 thorax (black in the Shillong species) but acts in an exactly similar 

 manner, the eggs being thrust into tender stems of cultivated rose, 

 whose leaves are defoliated by the larvae. This species is common at 

 Dehra Dun, and at Ramgaih (Kumaon District) in August 1918 I found 

 a rose-twig which had had eggs deposited in it in the manner charac- 

 teristic of these species, so that the Dehra Dun species probably occurs 

 along the central Himalayas generally. 



In Dehra Dun this sawfly is scarcely a pest, as we have to cut Mr. Beesoa. 

 back the rose-bushes periodically. 



It certaimy seemed to occur in large numbers when I was at Dehra Dun Mr. Fletcher. 

 last August. In the case of the Shillong species, whose habits seam 

 exactly similar, certainly every leaf on a rose-bush may be eaten and 

 the Vv'hole bush left leat^ess.

This species has been recorded from Nagpur, larva in juar stem, 

 and from Coimbatore, larva in juar, wheat, varagu {Paspalum scrobi-
