evening sweeping at the edge of the cliffs ; this very rare British species I once 

 found at Hurst, Sussex, and again, subsequently, at Caterham. Ehyparochromus 

 sabulicola : sparingly, in short moss, in a sandy place. Miridius quadrivirgatus : 

 sweeping along the cliffs, rarely. Teratocoris antennatus : both sexes, rarely, by 

 sweeping Arundo, Carex, Jtincus, &c., iu a partially dried up piece of marsh ground. 

 Nabis lineatux : not uncommonly, with the preceding. Cardiastethus testaceus : a 

 single example, by evening sweeping at the edge of the cliffs. — Q-. C. Champion,

Pachytylus migratorius, Linn4, in Lincolnshire. — Yesterday I received for identi- 

 fication a living female P. migratorius, L., from Mr. H. Wallis Kew, of Louth, 

 Lincolnshire, who asks me to record its capture. It was said to have been taken in 

 a field of stubble at Withern, eight miles from Louth, and was brought by a little 

 girl to the local taxidermist, from whom Mr. Wallis Kew obtained it. — Eland Shaw, 

 St. Mary's Hospital, W. : Oct. \6th, 1886. 



On the moulting of the larvcv of Pygara bucephala. — I have lately had an 

 opportunity of seeing a batch of these larvje undergoing their last moult, and was 

 much struck with the prolonged interval which elapsed between their being laid up 

 for the moult and the actual transformation taking place. 



It was on Thursday, September 16th, that I first noticed the larva ; they were 

 then taking up their position on an oak-twig, which was most conveniently situated, 

 as it was just the right height for the eye, and it was in a place that I habitually 

 passed a dozen times a day. 



On the Friday, September 17th, the larvse were all fixed in position, and I could 

 see by the amount of silken carpet spread over the leaves that moulting was 

 intended. They remained in this state all Saturday, all Sunday, and all Monday, 

 except that on the Monday one solitary individual banged its head about from side to 

 side, which I thought was a hopeful symptom. On Tuesday morning I must confess I 

 was somewhat surprised that not a single larva had yet moulted, though they had 

 begun to take up their position the previous Thursday, and, of course, had not tasted 

 food since then. 



Shortly after noon on Tuesday, the fii-st moult took place, the newly-moulted 

 larva was at once conspicuous by its pale yellow head, all the unmoulted larvae had 

 black heads, and the anterior legs were even paler than the new heads. The man- 

 dibles were jet black directly, and contrasted very strongly witli the pale yellow heads. 



Returning in half an hour, I found that two more had moulted, and I stayed 

 persistently watching them for some time, in hopes I should see the actual com- 

 mencement of a moult. Such tilings never will happen whilst you are watching for 

 them ; though I think I remained there motionless for three-quarters of an hour, no 

 fresh moult occurred. My contemplative position appeared, however, to have 

 attracted the attention of a robin, and he came and perched within two feet of me 

 and eyed me very keenly. 



At 1.30 p.m., I was obliged to leave my larvae for a while, but iu little more 



than half an hour I returned to them, but, alas ! that wicked robin had ; at any 



rate, the three newly moulted larva) had all disappeared, and a few of the others.
