ENDOTEICHA FLAMMEALIS. 63 



help from a powerful lens ; the head is rather darker 

 than before, the papillae are pale and translucent, the 

 collar-plate is blackish-brown, all the legs are pale 

 greyish-drab and rather transparent; the anal plate is 

 blackish on the front and side margins, brownish-grey 

 behind; the belly has a brownish-ochreous tinge, and 

 somewhat of this modifies the darker chocolate-brown 

 of the back, assimilating well with the few old decaying 

 leaves in spring that can yet be found lingering on in 

 the haunts of the insect. 



The cocoon, formed by the larva that was prema- 

 turely full-fed, on withering leaves of sallow on the 

 10th of November, was of a roundish oval figure, 

 composed of greyish-drab coloured silk, spun on the 

 under-side of one of the leaves and joined in part to 

 another; the silken surface exposed to view became 

 in course of the night following finished off with a 

 number of small particles of greenish leaf sprinkled 

 irregularly, over it, which adhering, gave just the 

 speckled aspect the under-side of the sallow leaf pre- 

 sented so often at that time ; both leaf-stalks were 

 fastened to the twigs with thick moorings of silk, and 

 one end of the cocoon being attached to the vessel 

 wherein it was kept for observation, seemed suggestive 

 of an innate habit under favouring circumstances of 

 securing the cocoon to some fixed object; a day later 

 it became needful for its removal to sever this attach- 

 ment, causing a hole exposing much of the larva to 

 view, and allowing me to note its already changing 

 colour; but it was quite equal to the mishap, for 

 within a few hours it spun a quantity of silk over the 

 hole and prevented any further observation. 



The above exceptional instance induces me to add 

 that all the other larvae of E. flammealis remaining 

 alive in spring spun themselves up during the last few 

 days in May, both with Mr. Jeffrey and myself, and 

 that one of mine was in an oval cocoon of 13 by 

 6 mm. diameters, covered with particles of earth and of 

 dead leaf, half sunk in the soil and attached to a dead
