LIMEXITIS SIBYLLA. 35 



At first they ate the young and tender shoots of 

 honeysuckle [Lonieera perwlymenum), and then the 

 lower leaves, reascending to the top of the bare stem 

 to undergo the process of moulting, with the exception 

 of one small larva, that spun the edges of a leaf together 

 and moulted within it ; thev then ate their wav down- 

 wards as before, and kept on the sunny side of their 

 food. They appeared to spin much silk along the stems 

 during their career, and to partly secure the leaves by 

 it in a suitable position to steady them during their 

 repast, and, in consequence, their long spines in front 

 became, in some of them, clogged and entangled or 

 tied together bv the silk in their twining* progress 

 among the leaves, though they appeared never wholly 

 to trust themselves from the stem, as their anal pro- 

 legs at least were always attached to it . As they reposed 

 along the spiral stem or bent aside to feed they were 

 verv eleeant creatures, assuming- the most graceful 

 positions. They seemed to like the sunshine, and 

 when exposed to it, appeared to be active and 

 hungry. 



In structure the body is of nearly equal width, the 

 second and anal segments being the smallest, the 

 divisions and transverse wrinkles well-defined, the 

 whole upper surface covered with transverse rows of 

 minute raised points, and on the third, fourth, and 

 sixth segments, a pair of long, tapering, branched, 

 subdorsal spines ; similar pairs, but rather shorter, are 

 on the eleventh and twelfth, while on each of the other 

 segments, except the second, are a pair of very short 

 similar spines, and two minute pairs of them on the 

 thirteenth : a row of exceedingly small spines are visible 

 above the spiracles. The spiracular region is distended, 

 forming a projecting ridge below, armed with very short 

 branched spines, a row of short simple spines above the 

 feet, and a ring of them round each proleg, and on the 

 ventral surface of each segment a central transverse 

 row of them. The head has the crown elevated, and 

 face sligvhtlv convex, the whole surface covered with
