gradually works downward until it encounters the brown sheath. It then 

 begins on a new needle. In the laboratory the caterpillars frequently ate 

 all the needles of a cluster, and showed no disposition to wander from the 

 first shoot supplied to them, frequently cleaning up the very last bit of 

 food before they sought another shoot. In nature I have never found 

 more than three or four neighbouring bundles which showed signs of 

 attack, and when the needles had grown to a length of an inch or more and 

 had begun to diverge, seldom more than one of them in any bundle had 

 been eaten. This would argue that the larvte move about so that their 

 depredations, by not being too marked in any one place, may be the less 

 easily noticed. 



My records show some discrepancy in the number of moults. The 

 larvoe brought from Lakewood moulted four times before pupating, and yet 

 I am certain that I had a memorandum of only three moults passed by the 

 Albany larvje raised some years ago. The loss of my material makes it 

 impossible to compare the size of the heads of the two sets of caterpillars, 

 but I shall endeavour to verify this observation at some future time. In 

 the last two stages the feeding habit is quite unique, and has resulted in 

 a structural modification. The caterpillar clings to the side of a needle 

 and bends its head and first segment at right angles to its body, as 

 illustrated in fig. 4. The structure of the first thoracic segment of most of 

 the Lyccenidcc is rather pecuhar, the anterior edge being greatly swollen, 

 the posterior half partially concealed by the segment behind. Just in front 

 of the thoracic shield the segment is deeply creased. In iiiphon this 

 crease is almost obliterated, and the white shield is drawn out from the 

 protecting second segment so as to be entirely visible.

 lunata is preoccupied by Friese for an African species, in Wiener
