38 LIMENITIS SIBYLLA. 



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 is 

 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. 



The ventral surface is bluish-green at the divisions, 

 and grass-green across the centre of each segment, and 

 whitish-green on the two or three last segments ; the 

 prolegs are tipped with pinkish. 



The head is pale pinkish or greenish, with a crimson 

 or brown stripe on each side of the face ; the mouth 

 pink, with the mandibles black; the whole face is 

 thickly studded with yellowish obtuse spines, with a 

 few black ones, the longest pair on the crown black. 



The subdorsal spines are reddish, crimson at the 

 tips, where they are branched with black, and below 

 they are yellowish. 



When full-fed the larva becomes rapidly paler, 

 and then suspends itself by the anal prolegs to a 

 stem* of the honeysuckle or other surface, and hangs 

 with its body downwards in a sinuous curve, with its 

 head bent a little upwards facing the abdomen ; it then 

 remains motionless for three days, becoming whitish 

 on the abdomen and remaining very pale green on the 

 thoracic segments. 



In the course of the third day the creature seems to 

 wake up, unbends its head, swings itself to and fro a 



* In order to ascertain the natural habitat of the pupa of this species 

 Mr. C. G. Barrett visited Woolmer Forest on the 14th of June, 1867, 

 and in the course of several hours' search found four pupae and two 

 suspended larvae of Limenitis Sibylla. Of these, five were spun up to 

 leaves of honeysuckle, and one to a leaf of Rhamnus frangula growing 

 contiguously, and in every case were firmly suspended to a button of 

 silk on the underside of the midrib of the leaf. Not a single specimen 

 was found attached to a stem or branch. — H. T. S. [E.M.M. iv, 35.]
