Ther sites. 



Dec. 18, 1913. Brought up from refrigerator two larvae hibernat- 

 ing in 3rd instar. 



Dec. 21. One of these has commenced eating. 



Dec. 25. The first has been feeding regularly and has eaten the 

 parenchyma of a good share of 3 or 4 small leaves about 5 mm. long ; 

 it does not show any very definite difference in size and appearance. 

 The second began to eat yesterday in the same sparmg manner as 

 the first began; they leave the upper cuticle of the leaf. Brought 

 up a 4th instar larva from refrigerators yesterday. 



Dec. 26. Two first larvae feeding, the third does not look very 

 happy, but moves about a little ; it has not commenced to eat. 



Dec. 27. No. 3 began to eat last evening and has by this evening 

 made a considerable mark (^ to ^) on a leaflet over half an inch 

 long, it leaves the upper cuticle. The other two are quiescent (for 

 moult?). 



Dec. 30. One of the two did some further eating on 28th. The 

 4th instar specimen made inroads on two small leaves last night; 

 so far as apjaears this evening all are resting. 



Jan. 2, 1914. 10 a.m. One of the smaller larvae has moulted 

 into 4th instar. The larger specimen (laid up for moult) is very 

 cryptic. I have not been able to see it for several days. To-day 

 removed leaves from box one by one and couldn't see it, nor on 

 going over them again ; but finally saw it under a small leaflet, with 

 which it agreed in size, and with the adjoining ones in tint and 

 colour. 



Jan. 4. 4th instar larva found this morning moulted into 5th 

 instar, colour dark greyish or olive green, with longish pale silky- 

 looking hairs rather abundant along dorsal and lateral flanges, also 

 below flange and some rather shorter ones extending down slope 

 a little way from dorsum, rather in the incisioias. No definite dorsal 

 or lateral lines. 



Jan. 9. 4th instar larva is now a good size, when contracted 

 11 mm. long, 4*3 mm. wide, and 3*5 mm. high. Very uniform in 

 colour, a deep blue green, a barely darker dorsal line, and a very 

 fine yellow thread deeply placed as lateral line; the silvery hairs 

 are still a feature of the larva, but are now sjiread enough not to be 

 conspicuous. 



The second larva appears to be laid up for last moult. 



Jan. 11. Large larva seems nearly full grown, it is at least large 

 and skin tight and shining. The yellow lateral line is more visible 

 than it was (more so from below), and is very slender. The colour 

 is a bluish green, it is 11 mm. long (retracted) and about 5 mm.
