Euclidia glyphica. — The eggs described were laid side by side on 

 cover of a box. Almost spherical in shape, except for the flattening at 

 the basal attachment, and a still slighter flattening at the apex. Of a 

 pale green colour when first laid, with opaque whitish patches running 

 round the egg transversely ; becoming darker green later. There are 

 about 30 faint, pale, longitudinal ribs running from base to apex, 

 ending just short of the apex on the ridge surrounding the micropylar 

 area. The micropylar area forms a shallow depression, at the bottom 

 of which the micropyle forms a tiny rosette. [Described August 1st, 

 from eggs laid by a $ captured at Aix-les-Bains. These eggs proved 

 infertile.] 



Acontia luctuosa. — The eggs described were laid singly on the inside 

 of a box. The Qg^ forms rather more than half a sphere laid on its 

 flat end. The newly-laid egg is of a pale yellow colour to the naked 

 eye, but under a lens the basal area is whitish, and the upper half 

 more yellow in colour. It is very finely ribbed longitudinally from 

 base to apex, with about 26 fine (but conspicuous) white, shiny ribs, 

 some of which unite before reaching the micropylar area, which 

 consists of a small reddish-broAvn depression at the apex of the eg^. 

 Two or three days after deposition the egg becomes entirely whitish, 

 with a row of red-brown spots just above its equator. The ten or 

 twelve surviving ribs form a very distinctly marked corona round the 

 edge of the micropylar area. [Described August Gth, from eggs laid 

 by a $ captured at St. Michel de Maurienne.] 



Phlltometra viridnria. — The eggs are laid closely side by side. 

 Each egg forms rather more than half a depressed sphere, but the 

 basal area is somewhat rounded. The newly laid egg is (August 20th) 

 of a clear pearly-white colour, covered with two sets of fine oblique 

 lines running from the micropylar area to the base, and dividing the 

 egg roughly into diamond-shaped spaces (with the long diagonal 

 extending in direction from apex to base), at each point of which 

 there is a distinct large, red-brown spine, standing perpendicularly to 

 the surface of the egg. The micropylar area is quite white, slightly 

 depressed, and very finely reticulated, with no spines. In a day or 

 two (August 22nd) the egg becomes very striking. It is now 

 surrounded with bright claret-red rings, one of which surrounds the 

 micropylar area, and another the shoulder of the egg, the remaining 

 parts of the egg remaining white'-'' in colour. The micropylar area 

 also remains white. The red bands are so far irregular, that cross 

 pieces occasionally unite the upper band with the lower. The lower 

 half of the egg is not coloured with red. By August 27th, the red 

 parts had much increased, although arranged distinctly as two separate 

 rings (with an occasional junction), and a red spot here and there now 

 occurs on the lower half of the egg. The spines are at this time very con- 

 spicuous, and each is seen to have a stumpy octagonal pyramid for 

 base, the eight sides of the pyramid being continued to form the sides of 

 the rhombi, previously described. There is a distinct secondary 

 ribbing ^ transverse) noticeable. This divides each rhombus into two 

 triangles by means of a slightly raised Avhitish thread, forming the 

 shorter diagonal. [The description was made under a two-thirds lens, 

 from observations made on August 20th, 22nd and 27th. Eggs laid by 



* The white parts look quite cream-coloured under a lens of low power. Under 

 a high one they a^jpear to be quite white. — J.W.T.
