form of the elytra in the several species in this genus (and also in 
Campylostira hrachycera) is only the result of an arrest of development, 
although the perfect form of some of the species is not known ; and 
this view is strengthened by the fact that when the elytra are short the 
wings are wanting.

Notes on the transformations of Limenitis Sibylla. — I am very much indebted to 
the kindness of Mr. Barrett, who most obligingly sent me, on the 14tli of May last, 
several examples of the larva of this species to figure, varying from half-an-iuch 
to their full growth of one inch and a-quarter in length. 
At first they ate the young and tender shoots of honeysuckle (Lonicera peri- 
clymenum), and then the lower leaves, re-ascending 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 ; they then ate their way 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 by the silk in their twining process among the leaves, though they ap- 
peared never wholly to trust themselves from the stem, as their anal prologs at 
least were always attached to it ; and as they reposed along the spiral stem, or bent 
aside to feed, they were very elegant creatures, assuming the most graceful posi- 
tions. 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, sub-dorsal 
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, two minute pairs of them on the thirteenth ; a row of exceedingly small 
spines are visible above the spiracles. The spiracular region 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 prolog, and on the 
ventral surface of each segment a central transverse row of them. The head has 
the crown elevated, and face slightly convex, the whole surface covered with raised 
points and simple obtuse spines, with a longer and sharper pair on the crown. 
In colour the back is of a bright full green, blending gradually into a paler 
tint at the sides : the minute raised points yellowish ; a white spiracular stripe 
conspicuous from the sixth to the anal segments, with a central yellow blotch on 
each segment ; the edging of branched spines white, beautifully relieved by a 
crimson or red-brown stripe beneath, beginning on the sixth, or generally the 
seventh, and ending on the tenth segment.
