however, to attack the plant in all stages of its growth, and at all 

 seasons of the year The caterpillar, however, which appears on the 

 matured plant during the manufacturing season is, according to my 

 experience, the green variety. Though these do not kill the plant, 

 they strip it of its leaves, and render it practically unfit for manufac- 

 ture." This report is published in u Indian Museum Notes/' vol. iv, 

 n. 4, pp. 195, 196 (1899). One specimen of the moth appears to 

 have been reared, and drawings of the caterpillar, pupa, and moth 

 were made which are reproduced on Plate xii., Figs. 5, imago ; 5 a, 

 larva ; 5 b, pupa, all x 2. It is noted in "Indian Museum Notes" 

 that the material was insufficient for identification, but the moth 

 appears to me to be a stunted specimen of a species of Caradrina, 

 Subfamily Tvijinae, Family Noctuidse. 



From March 19th to 27th, 1901, I made Mozufferpur, Behar, my 

 head-quarters, visiting the surrounding Indigo Concerns in search 

 of " The Indigo Caterpillar." During these eight days I met with 

 but slight success, as I was able to find only three newly-hatched 

 caterpillars at the Ottur Concern, which I was not able to rear. 

 The season was unusually backward owing to the cold and late 

 spring ; moreover, all the indigo had to be resown, as rain fell early 

 in March and destroyed all the crop. Searching the indigo fields at 

 night with a lantern in the expectation of finding the moth oviposit- 

 ing was also unsuccessful, no noctuids whatever being seen ; four 

 species of Pyralidas only were captured. The season was altogether 

 unfavourable for the indigo caterpillar, the wind being always from 

 the west and therefore a dry wind, there being no easterly moist 

 winds, which are said to be favourable for the insect. 



On 5th April, 1901, Mr. E. Macnaghten, Secretary, Behar 

 Planters' Association, Mozufferpur, sent a few indigo caterpillars 

 from the Pipra Concern, Tirhut, to the Indian Museum, Calcutta, two 

 of which produced moths, and from this material the larva, Plate XII, 

 Fig. 5a, the pupa, Fig. 5b, and the imago Fig. 5 were drawn. 

 The caterpillars pupated on May 1st, and emerged as moths on May 

 20th. 



From April 17th to April 24th, 1901, I again visited Mozufferpur. 

 At this period the indigo caterpillar had nearly disappeared, but I 

 succeeded after much searching in finding a few at the Bhichanpur 

 Indigo Concern, which I reared to the pupa stage, when they all 

 unfortunately died, producing no moths. Whether or no they were 

 Agrotis segetis I cannot say, but most probably they were. I was 

 informed that these caterpillars were more numerous about ten days 

 or a fortnight before my arrival, but that they have not been at all
