THE CANADIAN NATURALIST. 



ROYAL TIGER-MOTH. 



(Arctia Virgo.) 



F. — The lustre of the spots and marks on many moths 

 and butterflies, rivals the glitter of the precious metals : the 

 silver spots on the wings of the Spangled Orange moth are 

 exactly like those on some of the Fritillaries. 



C. — Some of the Zebra Hawk-moths, which I enclosed in 

 a box, laid several eggs, which were round, rather flat, 

 pearly white, of about the size of a small pin's head. They 

 were not deposited all in a place, like those of a Phalcena, 

 but singly, all about the box, slightly stuck on. In about 

 seven days they produced the young caterpillars, which, when 

 hatched, were about one-fourth of an inch long, all white, 

 except the anal horn, which was black, straight, and half as 

 long as the body. Not knowing their food, I tried them 

 with a great variety of leaves, and at length found that they 

 would eat those of the ash ; and I afterward found a solitary 

 egg of this kind attached to the leaf of an ash tree. I sus- 

 pect the caterpillars would have very materially altered in 

 form and colour, as they became mature ; but I had not the 

 satisfaction of proving this, as every one died in a day or 

 two after being hatched.
