24 PIERIS DAPLIDIOE. 



tion, and from being interrnpted at each segmental divi- 

 sion ; it passed over each ventral leg. The spiracles 

 were flesh colour, with paler whitish centre, very incon- 

 spicuous and situated on the yellow stripe upon the 

 second subdivisional ring of each segment. The belly 

 along the middle was glaucous and paler than the green 

 beneath the spiracular stripe. 



These larvae were fond of lying at full length along 

 the flower spikes, and several crowded together at the 

 summit in amicable companionship ; often they would 

 have the head downward, sometimes with the anterior 

 segments hanging free. Their movements when feeding 

 were slow and very graceful, as their flexible bodies 

 accommodated themselves readily to any inequality of 

 surface over which they glided ; they covered the stems 

 and other parts with fine silk threads, which proceed- 

 ing rendered their footing more secure. They seemed 

 quite as partial to the flowers as to the leaves and thus 

 varied their food. 



On the 28th of September one pupated on the leno- 

 cover of a cylinder and another a day or two later. 

 From that period, owing to the setting in of colder 

 weather, the remaining larvae became torpid and 

 seemed unable to move, and though a few fed a little 

 occasionally and spun themselves up, yet they only 

 became abortive pupae, dying in one or two instances 

 after the larval skin had burst, and whilst the ridge of 

 the pupal thorax was developing ; others dropped off 

 the stems unable to retain their hold, whilst a few 

 remained on the stems in their natural positions for 

 some days after they were dead. 



It was evidently proved by this experiment that 

 Dajplidice is quite unsuited to our climate, and is an 

 insect belonging to a warmer country. 



The pupa measures 7 J lines in length, being thickest 

 across the thorax and near the end of the wing covers ; 

 the head bears a projecting taper-point in front ; the 

 thorax is sharply keeled and humped on the back. 



When first disclosed the colour of the pupa is almost
