EMMELESIA ALBTJLATA. 5 



next day I looked for and found some more laid at 

 large on plants of yellow-rattle in the same locality. 



These eggs are oval and yellow, paler at first, and 

 becoming richer in tint afterwards, deposited on the 

 flower bracts. 



On the 9th of June the little yellowish larvae with 

 dark heads appeared, and a few days afterwards I 

 captured several others feeding in the green and tender 

 seed-pods of their food-plant. It is easy to detect a 

 larva, as the seed-vessel containing it looks discoloured; 

 but I could not perceive that they spun together any 

 covering for themselves, all I noticed being completely 

 hidden within the seed-pods. After a change or two 

 the larvae became dirty whitish in tint, the head, plate 

 on second segment, and tip of tail being dark. 



About the 30th of June they were full-fed, and were 

 then of a uniform pale primrose-yellow — no lines — but 

 the ordinary dots very small, brownish, with a few 

 bristles, the head brown, the horny plates on the 

 2nd aud 13th segments scarcely tinged with brown ; 

 spiracles brown. 



Soon after this date they changed to pupae, but be- 

 fore doing so, as far as I could see, they all left their 

 food and entered the earth ; and although I searched 

 diligently, I failed to find any pupae in the ripened 

 plants where I had previously taken the moths, eggs, 

 and larvae. (John Hellins, 5th October, 1865; B.M.M.,

The insect was abundant in a plantation at Grimes- 

 car, about a mile out of Huddersfield, in the middle 

 of June last (1867) ; and I derived considerable satis- 

 faction from watching them deposit their eggs ; they 

 flew from one flower-head to another^ staying but a
