2 TRYXALIS NASUTA. 

passes through during the year, where the eggs are laid and 
how long it spends in the young wingless larval stage. 
Localities from which reported. 
The distribution of the insect in India would appear to be 
a somewhat wide one. Madras and Bombay have reported 
the pest as causing considerable injury to crops. In 1897 the 
Deputy Conservator of Forests sent the locust from the Kangra 
Division in the Punjab, where it had inereased insome numbers, 
In Madras it formed one of the locusts which gave so. much 
trouble in the invasion of 1878. It, with several other species, 
probably breeds locally there as also in the other parts of the 
country it affects, 
Mr. Mollison, now Inspector General of Agriculture, sent 
the insect from the Bombay Presidency, where it had injured 
crops in the vicinity of Poona in 1893. Next year it did 
injury in Satara. This insect is also common in the Cape of | 
Good Hope, Senegal, Egypt- 
Relations to the Forest. 
This Zryxalis is said to have done considerable injury 
during the year 1897 to young plants of Pinus excelsa and 
bamboo (species?). Sowings of these species had apparently 
been made in various portions of the Kangra Division, and it 
was found that the locusts were biting off the young seedlings 
and either wholly or partially consuming them. The insect 
_ was accompanied by a companion named Oxya velox, these 
two being responsible for all the damage done. 
Protection and Remedies. 
It is not possible to prescribe with any certainty of success 
remedies for insects about whose life history so little is at 
present known, but where the operation is feasible, 1 would 
recommend that the young plants be dusted over a few times 
in the evenings with a mixture of quicklime and ashes. If the 
arsenic compound Paris green is available, a good mixture can 
be made with one ounce of the Paris-green, one “ounce of 
unslaked lime and three pounds of ashes. Powder the sub- 
stances together very finely, place them ina thin calico bag 
znd dust over the plants.
