and young and full-grown larv^ 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

{V nidentified Tenthredinid). 



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 larvK. 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. Beeson. 

 back the rose-bushes periodically. 



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

 last August. In the ease of the Shillong species, whose habits se^m 

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

 the whole bush left leafless.

 This fly, as noted in the reference given, has occurred in South Kanara 

 and Malabar as a pest of toddy, spoiling the juice.

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

 ■and from Coimbatore, larva in juar, wheat, varagu (Paspalum scrobi- . 

 culatum), Panicum frmnentaceum, maize and broom corn (a kind of 

 cholam).
