350 THE ENTOMOLOGIST. 



with a number of longitudinal keels; when one is removed from 

 the capsule, and cautiously, I may say judgmalically, pre- 

 sented to the larva, he will instantly recognise it, and, grasping 

 it firmly in his six legs, will consume it while still in that 

 position, just as a squirrel does the kernel of a nut that has 

 been cracked for him. On the lOlh of August, Mr. Bryant, 

 so well known as a careful observer of insect economy, pre- 

 sented me with eggs of this very pretty species ; but I was 

 then entirely ignorant of the food-plant of the larvae, which 

 died almost as soon as they emerged from the egg-shell. 

 Subsequently Mr. Bryant has carefully searched the seeding 

 spikes of the Euphrasia which he observed was growing 

 abundantly near the Caterham habitat of the moth, and 

 succeeded in taking the nearly full-fed larvae, which, with 

 his customary kindness, he has presented to me, and thus 

 enabled me to describe a larva totally unknown both in 

 England and on the Continent of Europe : the larvae were 

 full-fed on the 19th of October. — Edward NewDian. 



Description of the Larva of Pterophorus zophodactylus, 

 Dup. {P. Loew a, ZcW.) — Larva half an inch long, rather 

 stout : colour light yellowish green, semitransparent (to the 

 naked eye pubescent), with three rows of spines on each 

 side of the dorsal line, which is a very narrow, claret-coloured, 

 streaky mark, commencing on the ^nd or 3rd segment, and 

 dying away as it approaches the anal segment ; subdorsal 

 and spiracular lines not visible in some specimens, in others 

 slightly so as light streaks : spiracles dark rings : head 

 small, slightly darker than the body and retractile : the larva 

 tapering towards the head and anus. Pupa purplish flesh- 

 colour ; the wing-cases change to dark purple-brown about 

 two weeks after making up, and the moth emerges a few days 

 afterwards : the larvae feed upon the common centaury in 

 July, August and September ; but it is remarkable, alike of 

 this and some other plume-moths, that they differ fully a 

 month in their time of appearance ; thus, last year I bred 

 the species early in August; to-day (Sept. 19) my first per- 

 fect insect appeared, and I have still larvae not full-fed. —
