STAUROPUS PAGI. 67 



following morning. They seem to have fed on the 

 chaffy stipule of the beech leaves. 



On the 8th the first larva had moulted and the second 

 on the 9th ; the cast skins having the long anterior 

 leg-cases spread out to their full extent. On the 15th 

 I found that the one which was first hatched had died, 

 it seemed not to have fed since its moult. The other 

 was very lively having eaten two long pieces out of a 

 beech leaf, between the side-ribs down to the mid-rib, 

 it had also eaten a piece out of an oak leaf ; the larva 

 was very dark brown and glossy. 



This larva after its second moult fed remarkably 

 well up to the 18th, and on the 20th it had moulted on 

 the leaf-stalk, its old skin lying behind it on the stalk, 

 and had made a good meal after the operation ; it had 

 been laid up the day before with the second segment 

 very tumid. After its moult its head was darker than 

 ever. On the 25th it had grown to be rather over a 

 quarter of an inch in length exclusive of the erect tail, 

 the colouring very dark brown and extremely glossy. 



On the 21st of July the Rev. B. Smith kindly sent 

 me two more eggs of fagi of a different brood, they 

 had already changed colour and by the morning of the 

 23rd one was hatched and had eaten its shell, the other 

 had done so by the following morning. I kept them 

 separate placing both on beech leaves ; both had 

 moulted when I looked at them at noon on the 28th ; 

 one had only just completed its moult, for as I looked 

 at it I saw it withdrawing the filaments of the tail ; it 

 became very quiet and motionless lying along the 

 edge of the leaf, as though the operation had been 

 exhausting. 



On the 6th of August the first larva was laid up 

 preparing to moult, the second segment very tumid, 

 larger than the head ; at 11 p.m. it remained the same, 

 but when I looked again at 11.50 p.m. it had moulted 

 and was much lighter in colour than before. 



On the 29th of A-ugust one had been preparing to 

 moult for twenty-four hours or longer ; the real head,
