 cribes the egg of A. straminata .~\ 



Egg of Acidalia trigeminata. — Of a distinct oval in shape, laid on 

 its long side, the long side to the short side apparently as about 

 ■1 : 3. Very pale pearly-white when first laid, changing to a dull 

 leaden colour before hatching. The surface is completely covered 

 with regular pits somewhat hexagonal in shape extending from the 

 depression in the upper face to the base in oblique curves. This cen- 

 tral area forms a comparatively large depression on the centre of the 

 upper face, somewhat irregular in shape, its sides formed of 

 minute cells. The eggs were laid on June 21s.t. 



Egg of Acn)ALiA maeginepunctata (promutata). — The eggs are laid 

 somewhat irregularly, but glued so firmly that they cannot be removed 

 from the object to which they are attached without injury. The qqq 

 is somewhat oval in shape, with the micropyle at one of the narrow 

 ends. It is usually laid flat on its long side, but sometimes tilted by 

 overlapping an adjacent Ggg. The length : breadth : height as G : 8 : 

 2. With the naked eye the mature egg appears to be of a deep salmon 

 colour. Under a two-thirds lens, the Qgi^ is pale yellowish in colour, 

 with so much pinkish marking as to give the idea of an almost entirely 

 pink egg. It has a depression on its upper surface placed towards the 

 base, /.('., the narrow end opposite that which bears the micropyle. 

 This depression occupies about one-fourth of upper area, and gives to 

 the egg (viewed from above) a distant resemblance to a slipper. About 

 13-15 longitudinal ribs can be counted, running from micropyle to 

 opposite end. The micropylar end forms a terminal rosette, pale yellowish 

 in colour, in the centre of which the tiny micropylar cells are barely 

 distinguishable (under a one-sixth lens). Under a one-sixth lens, the 

 resemblance of the egg of this species, especially if it be tilted as it 

 were on another egg, so that its base (end opposite micropyle) partly 

 rests on the ground, to that of a Pierid, is very remarkable. The 

 depression on the upper surface is not strikingly conspicuous. There 

 is a slight narrowing from the middle towards the micopylar end, and 

 the longitudinal ribs in view are about 13-15. 8ome of these unite 

 and so lessen the number in the micropylar area, i.e., at the true apex 

 of egg. The longitudinal ribs are faintly crossed with transverse ribs. 

 If the depression mentioned above as occurring on the upper surface 

 could be removed, and the egg set up on end, instead of on its side, we 

 should have an Qgg very like the nine-pin egg of some Pierids. The 

 empty egg-shell is perfectly transparent. [Eggs laid about August 

 19th ("pale straw colour when first laid," H. E. Page), described 

 August 29th, hatched September 3rd.] .—J. W. Tutt. Awjmt, 1896.

P2gg-laying of Ccenonympha pajipiulus.— Eggs of ('. paiiip/iilus are 

 easily obtained, as the species lays very freely in captivity. I doubt if 

 the food-plant is even necessary, they seem to neglect it so. Most of 

 the eggs obtained this year were laid on the netting on the top of the 

 case. At first they are of a pretty green colour, and as, in captivity 

 at least, they always seem (when they do lay on grass) to select
