108 POLYOMMATtJS (lYOJENA) ADONIS. 



whitish-green, soon becoming a full but dull green ; 

 all the warts furnished with hairs which produce a 

 downy appearance. During the winter months the 

 green is replaced by reddish-brown, and again in the 

 early spring the larva becomes pale purplish-brown, 

 with the dorsal humps and the subspiracular ridge 

 showing pale ochreous-brown. After a moult, about 

 the end of March, the dull greenish hue comes back, 

 the paler marks becoming yellowish, and the hairs 

 black. 



The full-grown larva is about five-eighths of an 

 inch long, and a quarter of an inch wide, onisciform, 

 with the head small and retractile beneath the second 

 segment ; the segments deeply divided. There is a 

 double dorsal row of eight humps or segments three to 

 ten inclusive, enclosing a slightly hollow space, which is 

 broadest on three, and thence tapers gradually to ten ; 

 the side spreads out to a rounded ridge running round 

 the body, and hiding the legs from view when the larva 

 is at rest. 



In colour, the head is very dark brown ; the body 

 is deep full green, covered with tiny black specks, bear- 

 ing little blach bristles, which are longest on the dorsal 

 humps and sub-spiracular ridge ; on the top of each 

 of the eight pairs of dorsal humps is a deep bright 

 yellow longitudinal dash, somewhat wider behind than 

 in front ; these dashes form in effect two yellow stripes 

 interrupted by the deeply sunk segmental divisions ; 

 along the rounded edge of the sub-spiracular ridge is a 

 stripe of bright and very deep yellow going all round, 

 save a slight interruption on the sides of the second 

 segment ; on the second are two yellow dots just 

 above the head, and above them again two small 

 black spots ; on the third there is a very faint yellowish 

 dot half way between the dorsal and sub-spiracular 

 stripes ; just above the feet is a row of yellow longi- 

 tudinal dashes, brightest on the feet-bearing segments, 

 and in one example these dashes were curved upwards, 

 and united at the end of each segment to the yellow
