before the larva emerges. There are usually 38 bold vertical ribs, 

 which are carried well up to the top before they unite in pairs, so 

 that only about half the number extend up to the edge of the 

 micropyle, and between these the hollows are divided up by many 

 horizontal rungs. The diameter is -SSmm., and the height 

 •4.5mm. 



Mauiestra persicaritr. — Similiar in habit to B. brassictt, a batch 

 of about 50 ova was found on June 18th, on a gooseberry, and 

 another on May 30th, under a leaf of Lijchnis dioica. The ovum 

 is similar in shape and markings tc that of B. brassiccc, but the 

 number of vertical ribs is usually rather smaller, about 30 on the 

 sides, of which fifteen are carried right up to the micropyle. The 

 diameter is •7mm. and the height -Smm. 



Dianthu'cia capsincola. — I have found this ovum laid singly on 

 the pistil of a flower of Lychnis dioica. It is upright, oval, and 

 white in colour when fresh. The sculpture appears to be in the 

 form of a fine network of raised hexagons of very small size, 

 extending all over the shell. Length •9mm., width •75mm., thick- 

 ness -Gmm. Altogether a most surprising ovum to be found 

 amongst the Koctuidic. 



Diantlmcia cnciibali: Ovum found in July and August, laid singly 

 on buds and flowers of Silene infiata. Once on a leaf. Silvery-white 

 when newly laid, yellow-brown later, and pale claret when mature. 

 Nearly spherical, but flattened. Shell shiny, but under magnification 

 it shows a very minute hexagonal network all over. Upright form. 

 Length -BSmm., width •5mm., thickness •35mm. Almost as great 

 a curiosity as that of capsincola. 



Diantlufcia carpophaf/a : Singly on capsules of Silene maritiwa, in 

 May and June. White when newly laid, later pale rosy-brown, 

 and finally purplish. Hemispherical, with flattened base and 42 

 vertical ribs, bold and well defined, of which about half are carried 

 right up to the micropyle. Form upright. Diameter •65mm., 

 height •4mm. A remarkable contrast to those of cucubali and 

 capsincola. 



Fachetra leiicophaa : Laid in large masses near the top of tall 

 seeding grasses; sometimes on the seedhead. Time, early June. 

 Opalescent greenish-white at first, they afterwards develop a central 

 spot and outer ring of dark purple. Dark slate colour just before 

 hatching. Upright form. Hemispherical in shape with flattened 

 base. Sculpture, 44 vertical bold ribs, of which about half are 

 carried right up to the micropyle. Well defined lateral rungs 

 between. Diameter •8mm., height -Smm.
