Euchloe carda77i?nes. — On hedge-garlic, yellow when first laid, 

 but turns scarlet after a day or so. The transverse ribs are distinct 

 lines. 



Colias ediisa. — On clover, from Mr. Prideaux. 



Pvrameis atalanta. — Represents the Nymphalids, together with 

 the two following examples. Specimens from Mr. Prideaux. The 

 larva emerges at the micropyle. The egg is very beautiful under 

 the microscope. It has nine ribs, and traces of transverse ribs. 



Argynnis aglaia. — A^ery finely pitted between the transverse ribs, 

 and resembles a Noctuid egg in the manner in which the longitudinal 

 ribs run into each other towards the apex. 

 Brenthis se/ene on Viola odorata. 



Chionobas jutta. — Represents the Satyrids. From Mr. Tutt's 

 specimen. 



We now come to twelve photographs of eggs of the Lycaenida^. 

 Although they present, at least in some species, apparently but 

 slight difference in structure, I think it is quite possible for a careful 

 observer to name the species from the egg, bearing in mind also 

 that difference in size is of material help. 



Polyommatus bellargus. — Laid on Hippon-epis. 

 Polyommatus coiydon. — On a Lotus leaf. Sent by Mr. Tutt from 

 Abries ; laid on August 12th, hatched on September 14th. ^ 

 Polyommatus icarus. — On rest-harrow. From Mr. Prideaux. 

 Plebeius cegon. — On Erica cinerea. Is a large egg, has a waxy 

 appearance, and the angles of the network very indistinct. 

 Cyani?-is argiolus. — On holly. From Mr. Montgomery. 

 Cupido niiiiima. — On AutJiyllis vuliiei'aria. The smallest of the 

 Lyceenids. 



Nomiades semiargus. — On red clover. From Dr. Chapman. 

 Taken at Guurda. 



Chrysophanus phlceas. — On Rumex. 

 Callophrys rubi. — On gorse buds. 



Thecla w-album. — On elm twig. This egg was exhibited at a 

 meeting in 1898 by Mr. Dennis. In shape it resembles a meat 

 pie ; the central portion is of a greenish colour, and is provided 

 with minute hairs. 



Zephyrus betuke. — From Mr. Montgomery. The base of the net- 

 work is a circular depressed hole, and, contrary to the usual run 

 of the LyCcenid ova, the protuberances are larger as they approach 

 the micropyle, which latter is much depressed. The base of this 

 egg also has a fine network, the angles of which are not prominent 

 and do not form protuberances. 



Zephyrus quercfts. — From Mr. Carpenter. Is the largest of all the 

 Lycsenid eggs. The area surrounding the micropyle is raised, and 

 in this respect is unlike the other Lycjenids,
