THANAOS TAGES. 129 



top, they began to spin threads of silk and to pucker 

 up the leno into a fusiform shape ; the foundation 

 threads were very strong and thick, spun parallel to 

 each other, in a little transverse series at each end of 

 the retreat. The larva that was first on the leno con- 

 trived to complete its hybernaculum ; but the other, 

 after spinning the two bundles of parallel threads to 

 form the two ends of its intended winter quarters, was 

 unable to find the leno slack enough for puckering 

 into the required shape, and began again the next day 

 at another part, but was again defeated, and finally 

 relinquished its attempt on the leno, and went below 

 among the plants. Some weeks afterwards I found it 

 on the earth killed by mildew. The same fate befel 

 the one which I had sent to Mr. Hellins. 



The other slumbered safely through the winter, until 

 early in April, 1869 a ray of sunshine reached it, and 

 I saw the larva coming out as though in distress to 

 escape either the warmth or the strong light ; where- 

 upon I shifted the glass to a pot containing a violet 

 plant, and the larva crawled down the sides till it found 

 the violet leaves, and then selecting two near the 

 bottom in a shady position, in an hour it had spun a 

 retreat between them as they lay horizontally one below 

 the other. But I suppose this operation exhausted its 

 strength, for when, after waiting in vain for the 

 butterfly to appear at the proper time, I pulled the 

 leaves asunder, I found it had died without having 

 become a pupa. (W. B., 1, 70; E.M.M. VI, 233.)

On the 7th of June, 1883, I received from Herr 

 Heinrich Disque, of Speyer, a batch of eggs laid by a 

 female butterfly of this species on Glechoma hederacea. 

 "Why he had given her this plant on which to lay, I 

 cannot say. The shape of the head is hemispherical,
