hibernation (some dozens), and were placed in cellar, dead, 

 except five individuals of which two were of those in fourth 

 instar and three those in third. These larvae had left the 

 leaves on which they had laid up and were on muslin and 

 paper in a jar, which was covered with muslin and paper, 

 so that not much change of air probably occurred, and the 

 outer jar contained a small glass of water, so that desiccation 

 could hardly occur. On the other hand, there was hardly 

 any mould anywhere. About a dozen larvae in this jar had 

 died. In other receptacles under different conditions all 

 were dead. These surviving larvae do not seem of any high 

 vitality, and do not seem hopeful. Some opening buds 

 of Colutea were, however, found and supplied to them. 



March 6. — Found four of the above five larvae had died, 

 but one seemed alive and well. It was put on the plant 

 of Astragalus on which a living larva was seen late in the 

 autumn and the plant brought indoors. 



March 8. — The larva has taken its station on a very 

 small young shoot of the Astragahis, and another larva, 

 probably the one seen last autumn, is resting on the 

 ground close hy. 



March 11. — The larva wintered indoors is making itself 

 at home and eating a little on the young Astragahis shoots. 

 The other larva appears to be dead, though it looked 

 all right a few days ago. 



March 26. — The larva looked very sickly for some days, 

 and on 24th actually dropped off its perch, showing that 

 it had made no silken carpet, and it lay on its side 

 on the moss in the flower-pot where I placed it after 

 looking at it and feeling some doubts as to its condition. 

 This morning the empty skin, well distended as before 

 moulting, lay on its side, as I had placed the larva, but 

 the larva had emerged from it and had found some 

 growing material about two inches distant. 



March 29. — Tiie larva is now freely eating the half- 

 expanded leaflets of the Astragalus. It is 7'5 mm. long, and 

 is much darker than any autumn specimen at this stage, 

 almost as dark as the darkest autumn specimen at any 

 stage ; there is a dark dorsal band, then a greenish stripe, fol- 

 lowed by the dark lateral oblique bands which dominate the 

 rest of the slope and sides. The whole larva has a brown- 

 ish-grey effect, with green only on the broad subdorsal band, 

 which is not however continuous, but rather a series of 

 large patches one on each segment. The larva is probably
