LEPIDOPTERA. 
Cirphis (Leucania) includes two very common species known as 
pests in the plains. C. unipuncta, Haw., is the destructive “ Army worm” 
of world-wide distribution, whose larvse feed upon rice, maize, juar and 
other crops, occurring often in very great abundance. There is a 
voluminous literature regarding this insect, one of the best accounts being 
Try on’s (Queensland Agric. Journ., 1900, p. 135). He states that the 
moth lays 500 to 700 eggs, there being two broods yearly in Australia • 
abundant enemies and parasites check its excessive multiplication nor¬ 
mally. The larva may be known by the plate over the base of each 
suckerfoot, a character not found in other Indian injurious Noctuids. 
C. loreyi, Dup., is also found upon cereals, but the larva occurs also under¬ 
ground, feeding upon the roots of plants or coming out at night to feed. 
C. fragilis, Butl., is reported as having been destructive to wheat in 
Chindwara, but has not been found since that time as a pest. 
Borolia is most commonly represented by B. vencdba, Mo., whose 
larva feeds upon rice leaves. 
Polia (Hadena) is a large genus of moths superficially like Agrotis ? 
but with hairy eyes and tufts on the abdomen. P. consanguis, Guem>
