260 PKMPELIA CAKNELLA. 



plainer through September and October, when some 

 of the leaves and stems were spun to bits of stick, 

 placed there to keep the sprays upright, and prevent 

 their straggling over the margins of the pots. 



The plants became very dry, and so remained 

 through an unusually severe winter and spring, until 

 April, 1879, when a few fresh green shoots of the 

 Lotus, and, by chance, a few of Medico go lupdina and 

 Trifolium repens appeared round the outside of the old 

 dry portions of the former plants ; but it was as late 

 as the 15th of May when I first found a larva had 

 moved from its winter quarters, in the pot of Helian- 

 themum, where there also chanced to be growing a 

 young clover plant, of whose few leaves an unopened 

 one arrested my attention to two minute holes near 

 the top. On examination, a young P. carnella larva 

 was within a web which had held the leaf folded 

 together ; soon after this another larva was found 

 feeding on one of the leaves spun against the Helian- 

 themum, — facts pointing to a leguminous plant as the 

 proper food. On the same day Mr. Jeffrey examined 

 two or three dry old leaflets spun together, which I 

 had cut from the Lotus and sent to him, and within 

 them he found enclosed, in a tough white silken fusi- 

 form hibernaculum, a larva of P. Cornelia, alive, 

 though accidentally killed during the investigation. 



During a gleam of sunshine on the 19th of May, I 

 had great satisfaction in seeing that the small family 

 on the Lotus corniculatus had awaked from their six 

 months' sleep, as evidenced by five separate spinnings 

 of excessively fine glittering silk threads, one on an 

 entirely new stem with leaflets drawn over, hiding the 

 little tenant in possession, the others holding fresh 

 leaflets to old dry stems, with minute specks of fresh 

 frass clinsfino- to them. 



In the centre of the pot, old dead stems and leaves 

 were numerous, and amongst them silk threads began 

 to accumulate, and extend to many little new sprays of 

 the plants, so that by the 22nd there were two rather
