72 Psyche [June 



cocoon at the bottom of the jar beneath the felt, next to the glass. 

 The underside of the cocoon was incomplete and the larva was in 

 part visible through the glass. November 11, conditions about 

 unchanged. November 14, larva within cocoon beneath felt had 

 moulted (skin disposed as in the case of the other) ; soon after it be- 

 came comatose and remained so, as far as could be observed, until 

 the following May. November 18, the remaining and active indi- 

 vidual was still at cocoon-making, but this time in still another 

 location — at the bottom of the jar beneath the felt. November 21, 

 could not be located, but when jar was brought closer to the 

 light to facilitate the observation it came out of one of the previ- 

 ously constructed cocoons. November 25, within a more or less 

 incomplete new cocoon, close to the one which it forsook the 21st. 

 November 28, had moulted again; came half way out of cocoon 

 during observation but backed in again. December 2, left cocoon 

 during observation. December 5, again within one of its former 

 cocoons, and forsook it while observation was made. December 

 9, moving about freely. December 12, ditto. December 16, 

 within a rather loosely-constructed cocoon on bottom of jar, 

 beneath felt, like its comatose companion. December 19, 

 cocoon more dense. December 24, had moulted once more — third 

 time since its confinement. December 30, apparently comatose. 

 Both larvae, it should be said at this point, moulted once, in addi- 

 tion, after they had apparently become torpid, just when the 

 writer cannot say, the cast skins, evidencing this, being found in the 

 cocoons — at the hinder ends — the following spring, after the 

 emergence of the adults. It is interesting to note that in the final 

 moult the cephalic portion of the skin remains attached to the 

 rest of the skin; the dorsal or upper surface of the former splits 

 medianly and longitudinally and the larva either wriggles out, or 

 else pushes the skin off over its anal end. The interior of the 

 cocoons are lined with white silk. 



The moth which developed from the more active larva emerged 

 first and proved to be a male. It was first observed May 14 (1918). 

 It died May 23. The other moth (female) emerged between May 

 24, and May 26. In both cases, the empty pupal skin projected in 

 greater part beyond the end of the cocoon, as figured by Riley 

 (Ins. Life, II, 1890). 



Eggs were observed June 2, a. m., and they were numerous then.
