the winter, and are not difficult to find if carefully searched for. 

 They are upright, hemispherical, and pale purplish-brown in 

 colour, becoming much darker as they mature. The sculpturing i& 

 very bold and simple. A small depression in the centre contains 

 the micropyle, and twelve well-defined vertical ribs are carried 

 right up to this from the base. These ribs appear to be rather 

 lighter in colour than the body of the egg itself. Diameter 

 •75mm., and height 'Smm. 



Ochria anrar/o. — 1 have seen this §gg once wild laid singly on 

 a leaf-scar, near the tip of a beech twig. In shape it is similar 

 to that of C. citrarjo, but has fourteen or fifteen vertical ribs, and 

 six or seven of these (individuals vary) stop a little before the 

 rest. Between the ribs are many lateral rungs. Colour purplish- 

 brown, and rather shiny, with the raised parts of the sculpturing 

 distinctly lighter. Diameter -TSmm., height -Smm. 



Xantliia fulvayo may be found laid singly at the base of buds 

 of sallow, or between the bud and stem ; frequently several on the 

 same twig. They are similar in shape to those of C. citrat/o, but 

 have many more vertical ribs. The number of these varies 

 between 28 and 30, so far as I have observed, and about half of 

 them are perceptibly shorter than the others. Colour, pale purplish- 

 red, darkening with maturity till they appear to match the 

 surrounding bark. Diameter -Gomm., height -imm. 



CticiiUia verbasci. — I have found these ova, early in June, laid 

 singly on buds, stalk, and base of young leaves of mullein. They 

 are upright, hemispherical, and pale greenish-white in colour, 

 developing brown spots, scattered apparently at random, over the 

 surface of the shell. The sculpture is not very bold, and consists 

 of 30 vertical ribs, which unite before reaching the micropylar 

 area, only fifteen being carried right up. The diameter is •8mm. 

 and the height -Smm. 



Plunia moneta. — I have only found these in July, laid singly on 

 the flowers and calyces of monkshood. They are upright, hemi- 

 sperical, and pale orange-red in colour, developing a dark central 

 blotch, and becoming deep purplish just before hatching. The 

 sculpture is moderately bold, and consists of 28 vertical ribs with 

 lateral rungs between, and a well defined micropyle. Of the 

 vertical ribs ten are short, twelve more unite in pairs a little 

 further up, continuing as six, and only twelve eventually reach the 

 micropylar area. Diameter •7mm.,- height •45mm. 



Nemoria viridata. — The late Dr. Hodgson supplied me with wild 

 laid ova of this insect. They were deposited singly on the leaves
