emergence, that between 5 and 6 much less so. The imago emerged 

 some tmie during the day (June 11th). 



Length of larval life of Emydia cribrum. — It may be of interest 

 to you to know that some hliuijdia crihnun larv«, which I took hist 

 Easter, three parts fed, are still feeding. One pupated a week ago. —

Egg of Epunda lichenea. — Eggs laid closely side by side, but not 

 overlapping. Somewliat globular in shape (depressed sphere), and 

 pale yellowish in colour ; the more advanced eggs with a broad dull 

 orange band round the centre, and a dull circular patch at the apex. 

 About 36 well-developed transverse ribs running from micropyle to 

 base. Under a one-sixth lens the ridges stand out as distinct bead- 

 like bands, each adjacent pair becoming united towards the apex of the 

 Qgg, so that only about one-half the number of ribs passes over the top 

 into the micropylar depression. Faintly marked transverse ribs unite the 

 raised points of the longitudinal ridges. The micropyle is exceedingly 

 small, forming a tiny rosette of minute cells at the base of the 

 micropylar depression. A dark point is in the centre of the micropyle. 

 Egg described September 16th. Eggs hatched October 6th. I am 

 indebted to Dr. Chapman for the eggs. — J. W. Tutt. 



Egg of Epunda nigra. — -The eggs laid closely side by side, with- 

 out overlapping. Under a two-thirds lens they appear smaller than 

 those of E. lichenea. In shape, a depressed cone, the base to height 

 as about 3 : 2, so that the broad base narrows rapidly to micropylar 

 depression at the top. Colour of the egg, purplish, its upper half dull 

 orange below (a more advanced egg looks blacker) . Eibbed longitudinally 

 from apex to base, with transparent shiny ribs, the latter glassy- white 

 and shiny. The micropylar depression distinctly marked at apex, the 

 micropyle forming a raised central rosette of minute cells at the bottom 

 of the depression. Under a one-sixth lens, the colour resolves itself 

 distinctly into a yellowish basal area, with purple patches, and a 

 purplish upper area. There appear to be about 12 ribs passing over 

 from the sides into the micropylar area, and these are continued down 

 the sloping sides of the micropylar depression. These 12 ribs are 

 formed from a much larger number, which, running up from the base 

 towards the apex of the egg, unite in couples before they reach the 

 rim of the micropylar area, and then again in couples as they go over 

 the rim, thus making a total of about 4(S ribs, starting from the base. 

 These longitudinal ribs are raised bead-like ridges, with transverse 

 sculpture running between them. The egg-shell itself is perfectly 

 transparent. The larva eats its way out at the upper edge of the 

 egg, directly below the micropyle, which is not disturbed or injured by 

 the operation. I am indebted to Mr. Tunaley for the eggs. He 

 informs me that they were pale yellow when first laid. The eggs were 

 described on October 4th, and one larva hatched the same day. —

Egg of Pamphila comma. — Attached by base, which is somewhat 

 flattened. In shape it is a truncated cone, Avhite in colour, with a 

 conspicuous slaty-coloured, basin-shaped, micropylar depression. The 

 shell, under a two-third lens, apparently smooth ; under a one-sixth 

 Jens, minutely pitted ; the micropylar depression is edged with similar
