EMMELESIA BLANDTATA. 15 



seldom for some time until they had acquired a certain 

 amount of growth, and until the necessity for more 

 food compelled them occasionally to come outside and 

 attack fresh capsules, when they could be better 

 observed ; especially was this the case after their last 

 moult, when (like the larva of E. unifasciata, Ent. 

 Mo. Mag., Jan. 1870, VI, 187), they assumed a hand- 

 some dress admirably designed in harmony of aspect 

 with the food-plant for their protection, whilst living 

 for the remainder of their larval existence more or less 

 exposed ; for often they remained with their heads 

 buried in the seed capsules, and the greater portion of 

 their bodies resting outside, and motionless for hours 

 during the daylight; but the succession of brilliant 

 little flowers given forth by the plants seemed quite to 

 divert the eye from the larvae, and, moreover, their 

 assimilation to the stems and leaves was so perfect, 

 that even when one knew they were present on a 

 shoot, it was with difficulty they could be detected. 



The two most advanced in growth moulted the last 

 time in the evening of the 1st of September, the 

 others at intervals later, and the first entered the 

 earth on the 10th, more followed soon, and the last 

 on the 18th. 



The only moth bred as yet, a male, appeared on the 

 14th of August, 1881, and enabled me to make sure 

 of the species, though probably more will emerge in a 

 future season in conformity with the habit of some of 

 its congeners. 



Again, during this last August Dr. T. A. Chapman 

 most kindly sent me from Switzerland, amongst other 

 things, a good supply of euphrasy shoots (gathered 

 near Engelberg, some twelve or fifteen miles as the 

 crow flies from the spot where Mr. Hellins had seen 

 his moth the year before) on which he had detected 

 eggs, and from these Mr. Hellins has succeeded in 

 rearing to full growth about a dozen larvas evidently 

 of the same species, and has thus enabled me to sup- 

 plement my description drawn from the examples I
