PLECOPTERA REFLEXA. 95 
Life History. 
The larva hatches out about the middle of April and spends 
some weeks feeding upon young sissu plants, It descends to the 
ground and changes into a pupa beneath the surface of the soil 
towards the end of June. A week is spent in this stage, the 
moths appearing at the end of June and on into July. These 
moths lay eggs, probably on the young shoots of the sissu 
plants, a second generation of larve appearing at the beginning 
of August. This is as far as observations of the life history 
have at present been carried and from them we see that there 
are at least two generations of the pest during the year. 
The notes on the life history from 26th June onwards were 
made by Mr. B. O. Coventry in 1899. The writer found the 
young larve in the plantation in April tgor. 
Localities from which reported. 
This insect has been reported from Northern India, Poona 
and the Andamans. Mr. B. O. Coventry reported it from the 
Changa Manga Plantation near Lahore in 1899. 
Relations to the Forest. 
As far as is at present known, the larve confine themselves 
to defoliating young sissu growth. They do not apparently affect 
the older trees. With reference to the damage done Mr. B. 
O. Coventry wrote:— 
“ The larve do very considerable damage, as this year at least 100 acres 
stocked densely with one year old sissu coppice were denuded of every 
leaf ....... Thisisthe first year this plague has been noticed by 
me, although in the Changa Manga working-plan aay is made of 
larve having appeared in sissu coppice ... . 
Protection and Remedies. 
Until the full life history of the pest is known it is not 
possible to prescribe remedies. In this connection it is especi- 
ally important to discover the stage in the life history in which 
the winter is passed through. 
Points in life history requiring further observation :—

deposited.
