pupa suspended by the naked anal spike, but I do not 

 think this can be correct. 



Mr. G. F. Mathew informs me that he has watched 

 the female of this species dropping her eggs at random, 

 as she fluttered above some coarse grass. (J. H., 7,

HlPPARCHIA TlTHONUS. 



Plate Y, fig. 2. 



On 21st August, 1873, I captured some butterflies, 

 which at once laid eggs ; the larvse hatched September 

 15th ; they moulted about the middle of October. On 

 January 21st, 1874, they were about 3^ mm. in 

 length, on March 16th about 6 mm. ; by April 25th 

 they had grown to 12 mm. ; June 4th, some measured 

 19 mm., and were full grown ; the first imago was bred 

 August 18th. In 1885, June 20th, Mr. Bignell sent 

 me a larva taken with some Galathea larvae in the New 

 Forest ; it was then 18 mm. in length, and in a day or 

 two became 19 mm.; on July 1st it suspended itself 

 by the tail for pupation, became a pupa on July 5th, 

 and the imago appeared July 26th. I fed the larvse on 

 Poa annua, Dactylis glomerata, and other common 

 grasses. 



The egg is cylindrical, standing on end, the top flat, 

 but rising in two shallow steps, the sides with sixteen 

 ribs separated by wide grooves, the ribs continued over 

 the top to an irregularly- shaped central spot filled with 

 reticulation, the transverse lines shallow but regular, 

 the shell glistening, at first all over very pale yellow, 

 becoming in four or five days whitish with light chest- 

 nut brown blotches ; of these there is a large central 

 one on the top, and a strong band of them round the 

 egg near the top ; the rest are scattered. Just before 

 the larva is hatched the egg becomes pale purplish, on 

 which the markings are darker but not plain.
