run parallel with the ribbing, in a few hours. The egg is very dis- 

 tinctly ribbed longitudinally with about IG ribs, some of which, 

 however, unite before reaching the top. There are many fine transverse 

 ribs crossing the longitudinal ribs, and the spaces between. The apex 

 of the egg is very rounded, and formed of concentric rings of delicate 

 cells, in the centre of which is the micropyle. The latter forms a very 

 distinct stellate structure, even when observed under a low power. 

 [Described July 29th.] 



Acidalia iiiniiKtata. — The eggs of a delicate greenish-yellow colour 

 when first laid, with 10-12 prominent shiny, transparent, longitudinal 

 ribs. In two days the eggs become of a bright coral colour when 

 observed with the naked eye, but of a delicate pink, with scattered 

 crimson spots, under a lens. In shape the eggs form an almost perfect 

 cylinder, with ends only slightly rounded ; length : breadth : : 5 : 8. 

 There is no trace of a depression on the upper surface, and the trans- 

 verse ribbing is exceedingly fine. The longitudinal ribs form around 

 the edge of the micropylar area an external ring of raised points, 

 enclosing a series of concentric cells, with which the micropylar area is 

 covered. [Described July 29th.] 



Acidalia caricaria. — Oval in outline, the micropylar end much 

 broader and more flattened than its nadir ; length : width : : 5 : 8. 

 Some of the eggs are laid on the long side, others are attached by the 

 narrow point, the micropyle at the top of the egg. The colour is of a 

 pale apple green ; the shell is shiny, with 9 or 10 longitudinal ribs 

 reaching from base to apex, and crossed by many fine transverse ribs. 

 The terniini of the longitudinal ribs form a raised boundary sur- 

 rounding the micropylar area. The micropyle is very finely reticu- 

 lated, and is composed of radiating cells. [Described July 27th.]] J3y 

 July 29th, these eggs had changed to a pale straw colour, with a 

 slight greenish tinge, speckled with bright red. 



Xi/i/aena carniolicu. — Eggs laid on side of box, in close contact 

 with each other, on their long sides. Oval in outline, length : 

 breadth : : 3 : 2, with a large shallow oval depression in centre of 

 upper surface. Colour, dull yellow, with traces of longitudinal ribbing 

 evident. No other structure can be made out with a two-thirds lens 

 used as a hand glass. [Described July 29th.] 



Zi/(/aena tramalpina. —Figgs laid on long side in close contact with 

 each other, as a lower layer, a second layer being placed above. The 

 eggs are bright yellow in colour, somewhat oval in outline ; length : 

 breadth : : 3 : 2, with an oval depression on the upper surface. The 

 eggs are somewhat plumper (fuller) than those of Z. caniiolira. 

 Under a two-thirds lens the eggs look almost uniformly pale yellow, 

 but rather brighter towards the micropylar end, and somewhat trans- 

 parent towards its nadir. [Described July 29th.] 



Ox THE PUPA OF Chrysophanus amphidamas (heli.e). — I havc some 

 twenty-five pupae of this species before me, which I received from 

 Herr Voelschow, of Mecklenburg. Two are attached by the cremaster 

 to a slight silken pad, spun on a piece of leaf ; the others are quite free 

 of attachment. There is no trace of a girth, and the ventral surface 

 is so flat that the loose pupa almost always rests on that surface. 

 There appears to be considerable variation in the depth of the ground 

 colour, some being of a pale, almost transparent, grey, ventrally, and 

 dorsally on the thoracic segments, the abdominal segments being
