orbicular elongate, with a dark streak from it to the reniform ; the 

 claviform very elongate, and filled in with black. Habitat: South 

 Africa ; North-Western Himalayas ; the Punjab ; Sikkim ; through- 

 out the Bombay and Madras Presidencies; Ceylon, Expanse: 38 

 millim. [1*45 inches.] In the Indian Museum, Calcutta, are speci- 

 mens from Karachi, and Kulu and Solon in the Western Himalayas. 

 Hampson gives three synonyms, Agrotis exigua, Kollar, A. spiculi- 

 /era and A. aristi/era, Guene'e. 



The one species of butterfly and ten species of moths which follow 

 were all bred by me at Seeraha, Champaran, Behar, during the months 

 of August and September, 1901. They weie all found on indigo 

 plants of considerable height, which were being cut for manufacture 

 of the dye at the end of the mohran and beginning of the kunti 

 mahai. Though many of these species were brought in in large 

 numbers in the caterpillar stage, none of them can be said (at any 

 rate at Seeraha and in the present season) to be doing any consider- 

 able damage. They all eat the leaves of the indigo and thus reduce 

 the produce, but as the plants grow very thickly the damage done is 

 hardly apparent. Nevertheless they must reduce the quantity of dye 

 produced to a certain extent, and it is quite possible that in years 

 favourable to them they may do very considerable damage. 



6. Chilades trochilus, Freyer. Family Lycsenidse. Sub-order 

 Rhopalocera. Order Lepidoptera. 



This little butterfly has a very wide range, being found in South- 

 Eastern Europe, almost throughout Africa, Syria, Arabia, Persia. 

 Trans-Caucasia, the Pamirs, throughout India, Ceylon, Java, Bali, 

 Sumba, Sambawa, and in Australia. In India the larva has been bred 

 previously on Zornia diphyl/a, Pers , Natural Order Leguminosse, and 

 Heliotropium strigonum, Willd, Natural Order Boraginex ; it has not 

 previously been found to eat indigo. It has several synonyms, 

 Lycsena />&//*, Kollar, Lycsena isophthalma, Herrich-Schaffer Lycsena 

 parva, Murray, Lycsena glioma, Snellen. The following description 

 is taken from specimens found on indigo \*~ Larva : Length when 

 walking -4 of an inch ; onisciform, of equal breadth throughout, both 

 ends rounded ; pale green in colour of the exact shade of the young 

 indigo leaves on which it feeds ; a slightly darker dorsal line edged 

 with lighter green, also some similarly-coloured very faint diagonal 

 lateral lines each crossing two or three segments; a prominent lateral 

 continuous whitish line ; the whole surface shagreened and sparsely 

 covered with fine black hairs ; the head very small, black, usually 

 entirely retracted beneath the second segment; the constrictions 

 between the segments shallow ; apparently no mouth-like organ in
