Euchloc airdamines. — 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. — Very 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 selene on Vio/a odorata. 



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

 specimen. 



We now come to twelve photographs of eggs of the Lycaenid?e. 

 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. 



Polyommatiis bellargus. — Laid on Hippoa-epis. 

 Folyommatiis coiydoii. — On a Lotus leaf. Sent by Mr. Tutt from 

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

 Polyommatiis tca?'us. — On rest-harrow. From Mr. Prideaux. 

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

 appearance, and the angles of the network very indistinct. 

 Cyauiris argio/iis. — On holly. From Mr. Montgomery. 

 Ciipido minima. — On A/it/iy//is vuliwraria. The smallest of the 

 Lyceenids. 



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

 Taken at Guarda. 



Chrysophanus ph/ceas. — On Rumex. 

 Callophrys rtibi. — On gorse buds. 



Theda iv-albiim. — 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. 



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

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

 of the Lycaenid 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 querciis. — 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 Lycaenids.
