batch bred from the eggs sent me by ]\Ir. Doubleday. It had the ground colour 

 of a pale pea-green, with dorsal and subdorsal lines like the last, only on each of 

 the fifth, sixth, seventh, eighth, and ninth segments, it had a longish dash of dark 

 brown immediately below the sub-dorsal line. 



The third variety was also peculiar to the brood from Epping. It had the 

 ground colour of a very pale drab, dorsal and sub-dorsal lines pure white ; on each 

 side of second segment, behind the lobes of the head, was a blotch of dark brown ; 

 down the back, in the centre of each segment, was a dark brown triple wedge-shaped 

 mai-k, and at each segmental division a black spot ; the sub-dorsal line bordered 

 below, throughout its length, with dark brown dashes. 



One might indicate several more varieties, but I shall include the rest under one, 

 as they have the same markings, and differ chiefly in depth of colour. 



Ground colour yellowish-green, full green, sometimes dark olive ; dorsal and 

 subdorsal lines varying also with the ground colour, in the darkest specimens 

 becoming much suffused, and interrupted at the segmental divisions by a dark 

 brown transverse band ; second segment with the two large round dark spots j on 

 the back of each of the other segments a dark brown mark, compared by 

 Mr. Buckler to two leaves pointing forward, with a short stem between them, and 

 preceded by two black dots; sub-dorsal Hues bordered below with dark dashes. —

Offer of Zenzera mscuU. — Having about a couple of dozen duplicates of this 

 insect in fair condition, I shall be happy, on receipt of a suitable box and return 

 postage, to supply (until my stock is exhausted) any Entomologist who may be in 

 want of the species. — J. B. Lynch, 6, Leighton Crescent, Camden Koad, N.W., 

 May, 1865. 



Larva of Cwnonympha Davus. — Through the kindness of Mr. Joseph Chappell, 

 of Hulme, near Manchester, I have received three fine healthy larvae of Ccenonym' 



pha Davus, feeding on Aira — ?. They are from 10 to 11 lines in length ; grass 



green, with dorsal vessel darker green, bordered on each side by a yellowish-white 

 line ; and with slender yellowish- white sub-dorsal and spiracular lines ; the bicuspid 

 caudal prolongations are in a line with the sub-dorsal lines, yellowish-white at the 

 sides, but tipped with pink ; the head is green, but dull and lustreless, with much 

 the appearance of the head of a saw-fly larva ; the belly, legs, and prologs are 

 green. 



When examined through a lens, the entire surface of the body is seen to be 

 dotted all over with extremely minute white dots. 



The movements of the larvas are extremely slow and deliberate. — H. T. Stainton, 

 Mountsfield, Lewisham, May I7th, 1865. 



Further notes on thatch — Great part of the last summer has been so hot, with 

 bright sunshine day after day, that I have been quite unable to obtain as much 

 knowledge of the summer thatch-frequenting L&pidoptera as I should probably have 

 done had there been more cloudy or stormy weather. I have, however, devoted 

 a great deal of time to collecting from thatches, and, in the latter part of the season 

 with very fair success.
