4 APPLE. [1900 



of the chrysalis, which previously I had not been able to find recorded, 

 or to describe in detail myself. 



The Rpecimen of larva, or caterpillar, which I especially examined 

 was lying in its tunnel beneath a bunch of buds, together with "frass," 

 that is, the dirt and powdery results of its larval workings. The 

 caterpillar was, as nearly as possible, a quarter of an inch in length, 

 and, at a general view, of a brownish colour. When seen magnified, 

 the head was darkish, black at the back ; the next segment greyish 

 above, with a light line along the middle ; the succeeding segments 

 pale ochrey, or yellowish, with a transverse band of chestnut colour 

 above. This band was very little observable on the foremost segment, 

 but increased in width until at about the fourth segment from the tail 

 extremity the segments above were wholly brown ; the caudal segment 

 dark brown or black above. Spiracles chestnut colour, with slight 

 markings of same colour beneath them. Under part of the body pale ; 

 sucker- feet dark. 



In the various specimens of larvae which I examined there was a 

 slight difference in colouring, presumably from difference of age. In 

 one instance in which the larva was somewhat injured in withdrawing 

 it from its burrow, all that was noticeable was quite similar to the 

 above. In another, the larva, which was presumably younger, was 

 similar to the two above in colouring of head, next segment, and also 

 tail segment ; the intermediate segments paler, and colour along the 

 back similar. 



In about eleven tunnelled shoots which I examined, sent me from 

 near Worcester about May 23rd, a larva was present in its tunnel in six 

 instances. 



In such specimens of attacked Apple shoots as I opened from about 

 two dozen sent me from Polegate, Sussex, on May 28th, I found the 

 caterpillar present in several instances, and with somewhat greater 

 variety in size and tint of colouring. In the largest specimen the 

 reddish colour was more generally prevalent, and the four pairs of 

 sucker-feet beneath the body, which showed plainly, were pale or 

 white ; in a quite young specimen the four pairs of sucker-feet were 

 only just visible. 



In a supply of attacked shoots sent me from near Hereford on 

 June 5th, I found the caterpillar present in one instance, but I did 

 not find any chrysalids present up to this date. From the circumstance 

 of various of the shoots from different localities which I opened having 

 been obviously bored by the larva and deserted, I presumed that in 

 these instances the larva had, as is its occasional habit, turned to 

 chrysalis stage partly exposed at the outer end of its burrow, and had 

 fallen out.
