From this time their beliaviour was most satisfactory. Luckily 

 they were all of different ages, though all in their last moult, and I 

 was able, without anxiety for the others, to devote my whole energies 

 to one at a time ; and so in turn they all sat to me — or rather I may 

 say ate before me — during eight days while I was closely at work, and 

 never sulked or shraiik wlieu the sun shone on them, or when for 

 closer inspection I took them in my hand : only as each matured, and 

 ceased feeding, it grew active and lively, and exhil)ited its capacity of 

 walking at a great pace for a day or two before settling down to its 

 change. 



The smallest of the four had, apjiarently, just undergone its last 

 moult when it i-eachcd me, and it was then just one and a quarter inch 

 long ; the dates for their making up Avere respectively August 8th, 

 14th, 17th, and 18th. The earliest pupa Avas figured on the 21st of 

 October, when, on searching for the others, the latest larva was found 

 to have died without turning, although it had made a perfect cocoon. 



Emboldened by a former success in forcing several galii to per- 

 fection in 1870 — 71, I resolved to hazard the three pupae of eupliorlice 

 in a similar experiment. On the evening of the day in which I had 

 disturbed them, I packed them in the forcing box with moss, and 

 placed them at first on the iron plate of a kitchen stove over the 

 boiler ; here the situaiion was warm through the greater part of the 

 night, and quite hot by day, when the bottom of the box was elevated 

 two inches above the hot plate by aid of two strips of wood on which 

 the box rested ; Iiere they were damped witli lukewarm water twice a 

 day ; on the 23rd November, a fine and perfect moth came from the 

 earliest pupa, but after that my efforts were baffled ; the two remaining 

 pujjSB continued lively, but the moths would not appear ; I moved the 

 box to a place before my sitting room fire, but without effect ; and at 

 last I came to the conclusion that I ought not to have hegun the forcing 

 till the iceather had become dry and frosty ; then the heat woiild have 

 had due effect, but as it was, the great liumidity of the atmosphere 

 had prevented this, and sullicient heat had not reached the pupa; to 

 develop the imago in them at once. 



After continuing my forcing till tlie end of December, I put tlie 

 pupa? aside to wait for suunuer, but before that time came they had 

 died. 



Of course I can say nothing of tlie larva when young, but I may 

 notice the appearance of tlic two smaller ones when they first came 

 to me. The ground coloin- of Ihe smallest was black ; the next in 

 size was blackish-green, and with a muUitude of small bright yellow
