Cirphis unipuncta [“ South Indian Insects,” p. 376, tab. 18] is 
widely distributed throughout India and is often a major pest of rice. 
We have examples reared on rice-plants from Poona, Pusa, Chittagong, 
Mymensingh, Goalpara, Dibrugarh, and Kamrup, but it also occurs 
throughout Madras, the Central Provinces and Burma. 
Control is difficult and I do not think that any standard method 
can be laid down, largely because this species usually appears suddenly 
in large numbers, whence it has been called the “ Army Worm.” Un- 
attacked areas may be protected if possible by trenches and oiling of 
intervening ditches. The caterpillars hide during the day time under 
clods and in cracks of the soil and pupation occurs in similar situations. 
When fields are badly attacked it is advisable to plough them as soon as 
possible after the crop is removed, to kill the pupe remaining in the 
ground. 
With reference to the sudden appearance of large swarms of this 
caterpillar, there is a note by Laurent in the Entomological News for 
January 1915 [Vol. XXVI, page 36] on an outbreak of C. unipuncta 
in Philadelphia in 1914, and Laurent states that it has often been 
“noticed that the army worm oftimes becomes a plague when a wet 
season follows a dry one, and this was just the condition of affairs around 
Philadelphia in 1914.” In that case spraying with Lead Arsenate 
and sieving of dry slaked lime over the infested areas were found effec- 
tive control measures ; but such methods are hardly practicable in the 
case of rice areas in India, as a rule. It would be interesting to know 
whether there is any general rule in India governing the appearance 
of swarms of these caterpillars and in this connection exact informa- 
tion of any such outbreaks will be very useful. 
In Burma Cirphis unipuncta is very serious in some districts. Mr. Shroff, 
In Assam Cirphis unipuncta appeared last year just after the floods. Mt. Gupta. 
In Southern India, Cirphis unipuncta has been observed to appear M. Ramakrishna 
after heavy rains. ATvae:
