 Alpine species of Ziji/aoia.

Eggs of Lepidoptera. — Fiihniia cunsiiiciuita. — Attached by flat 

 side, in crevices, or against the roughnesses of the box in which the 

 eggs are laid. A flat oval in shape ; the micropylar end rather 

 narrower. Length : width : height : : 4 : 3 : 2. A rather deep de- 

 pression, markedly cellular in appearance, occupies the greater part 

 of the central area of the upper surface. Colour green, with a series 

 of raised longitudinal ribs running the whole length of the egg, and 

 crossing the central depression. Fifteen of these can be counted on 

 the upper half of the egg. They are apparently made up of a large 

 number of raised whitish points, arranged longitudinally, and united 

 transversely by short raised ribs running obliquely between the 

 longitudinal ones, so that the egg in some positions appears to be 

 honeycombed all over. The shell is shining, and white ; the embryo 

 within of a distinctly darker green colour. The micropylar area does 

 not present a very distinctive appearance. It is composed of a rosette, 

 formed of the endings of the longitudinal ribs, the micropyle proper, 

 consisting of a smaller but similar rosette, situated centrally within 

 the outer one. [Eggs laid April 22nd, described April 26th, 1897, 

 under a two-thirds lens.] 



Xiuiwria pnlceraria. — Uf a plump oval in outline; length : breath : 

 height : : 4 : 3 : 2|, with an oval depression on the upper surface, 

 occupying about half the upper surface. The shell reticulated with 

 delicate hexagonal pittings, the pits arranged somewhat longitudinally, 

 and more distinctly developed in the oval depression of the upper 

 surface. Colour pale yellow, to the naked eye, pearly white under 

 lens. The micropylar area is at the narrower end, not easily distin- 

 guished. It is composed of slightly elongated cells, arranged concen- 

 trically, with the narrower end of each cell pointing towards the 

 micropyle ; two rows of such cells visible, the inner one smaller. 

 The micropyle proper is a very minute delicate stellate structure, 

 situated in the centre of the micropylar area. The eggs (received from 

 the Rev. C. R. N. Burrows) were laid indiscriminately, but singly, on 

 the leaves of the food -plant and surface of a chip box, on April 25th. 

 [Eggs described April 26th, under two- thirds lens.] 



Aleuci-s pictaria. — Two eggs laid in the fork of a twig of sloe, a 

 single egg in another fork. To the naked eye they appear to very 

 closely resemble the colour of the bark of the sloe. Under a lens the 

 eggs are seen to be almost covered with a number of tiny, short, stiff, 

 pieces of transparent material resembling coarse silk, intermixed with 

 black particles, probably broken scales, but with a distinct superficial 

 resemblance to particles of coal dust. The eggs are so far covered 

 that the structure is entirely obscured, and the eggs have to be washed 

 for description. The egg is cylindrical, with rounded ends, the 

 length : breadth : : 3 : 2. It is of a pale yellowish colour, becoming 

 redder as it approaches maturity. The egg-shell is shiny, transparent, 

 the contents of the egg examined (well advanced in development) of 

 an almost uniformly blood-red colour. The central area of the egg is 

 exceedingly minutely pitted, but at the two ends the pitting is much
