STERRHA SACRARIA. Ill 



cords the capture of a female of this species near 

 Worthing on the afternoon of the 19th of August. 

 That same day she laid seven eggs, which were forth- 

 with entrusted to me, and I am happy to say I can 

 now give a good account of six of them, one unfortu- 

 nately having been crushed in the quill during its 

 journey. 



The larvae were hatched on the 29th of August, 

 reached full growth and spun up between the 20th 

 and 30th of September, and the six pupae at the 

 present date look lively and well. 



The shape of the egg is singular — a very long 

 narrow oval, with the under side flattened, and, when 

 seen under an inch lens, it appears to be finely dotted 

 all over, as well as ornamented with rows of hexa- 

 gonal network ; its colour when first laid is a pale 

 greenish -yellow, changing in a day or two to a bright 

 coral-red, and from that to a smoky-grey a few hours 

 before the escape of the larva. 



The larva on its first appearance is translucent and 

 whitish, with a broad (that is broad in comparison to 

 the bulk of the tiny creature) purplish-red lateral 

 stripe, as pretty a youngling as I ever made the 

 acquaintance of in my experience of lepidopterous 

 larvae. 



At the end of a week the length was about five- 

 sixteenths of an inch ; the white colour changed to a 

 soft grey, the lateral stripe brownish-red, and com- 

 paratively narrower than at first. 



After another week the length was about nine- 

 sixteenths of an inch, the lateral stripe gone, and the 

 colour either a pale green or greenish-brown on the 

 back, with the belly grey. 



About the middle of the third week the last change 

 of skin took place, and the larva began to put on its 

 mature appearance. 



When full-grown the length is a full inch. The 

 shape is slender, cylindrical, tapering very gradually 

 towards the head; the skin smooth with a few bristles,
