situation not being favourable, they were laid in the 

 form of a wheel, of which her body was the radius, 

 as represented in the following figure : 



The rim of this wheel was about a quarter of an 

 inch broad, and regularly sloped like a candle shade, 

 and had down laid all around it in an imbricated 

 manner. Another of these captives, although in a 

 box of the same size as the other, instead of forming 

 a wheel, laid the eggs in a conical form, like a little 

 mound. The Professor conceives that this form 

 might have been assumed in consequence of the 

 moth, in all probability, having laid part of the eggs 

 before being captured, as it did not contain above a 

 sixth of the number which the other deposited. The 

 same general slope was, however, preserved, and it 

 was as regularly thatched as the other, as represented 

 in the following figure : 



These eggs produced, when in the possession of Mr 

 Rennie, in April, 1830, a numerous brood of 

 caterpillars.
