more nearly allied Japanese species is now proved 03' breeding to be distinct), that

 1875, p. 247. — General aspect of C. macromera, but duller; primaries above golden- 

 olivaceous, with the two oblique bands and border dull greyish-pink ; secondaries 

 with basal half dull black, external half dull pink, fringe whitish ; body altogether 

 duller ; wings below bright rose-red, costa ochreous, a central grey-brown transverse 

 line ; basal half of primaries brown, clothed to first median branch with ochreous and 

 pink hairs ; body below rose-red, abdomen with lateral white dots. Expanse of 

 wings 3 inches 2 lines. Simla (coll. F. Moore), N. India. 



Egglaying. — Usually laid singly, or more rarely two or three 

 together, on the underside of the leaves of Galium palustre, usually 

 attached just where the leaves join the stem. Eggs found by 

 searching at Potter Heigham, June iQth-2oth, 1896 (Bacot). Laid 

 singly on the underside of the leaves of Galium palustre, Epilobium 

 angustifolium, and more rarely on E. hirsutujn ; sometimes two 

 eggs are found on one leaf, and once I found two in contact, but 

 as a rule they are placed singly. Eggs found by searching, July 

 1 5th-i6th, 1 90 1, on which date, besides three smaller larvae, one 

 about three-quarters grown and another 3 inches in length were 

 found, a sufficient illustration of the difficulty of fixing any par- 

 ticular date for the time of egg-laying, even in a single year. 

 The plants must be most carefully examined or the eggs may very 

 easily be missed (Ransom). Eggs taken on wild balsam at 

 Godalming on July 8th, 1901, young larvae being found on same 

 date (Latter, in lift.). Enclosed $ on a bunch of Galium palustre, 

 she oviposited in due course, the similarity of the eggs to the 

 seed-pods of this plant is noticeable ; the egg-stage only lasted 

 7 days (Butler, in lilt.). In the Reading district the eggs appear 

 usually to be laid two or three together on a leaf (Holland) ; laid 

 singly at the end of June on the leaves of Epilobium hirsutum 

 and Circaea luietiana, also, in London gardens, on the several 

 varieties of fuchsia (Newman). 



Ovum. — i^mm. in length, i.'jmm, in width, i'2mm. in height; 

 rather a short, rounded oval, colour green (less vivid than that of 

 the Amorphid eggs) matching w ? ell the colour of the leaves of 

 Galium palustre ; the surface shiny ; the surface reticulation faintly 

 but clearly marked (Bacot). Of a pale green colour, almost 

 circular in outline, but still just a little longer than wide ; the shell 

 apparently smoo h, but covered with a faint surface reticulation ; 

 a distinct depression on the upper surface of egg ; the micropyle 

 is very indistinct and consists of a finely pitted depression at one 

 end of the egg. When the embryo is fully formed, the eggshell 

 is transparent and has an iridescent gloss (Etit. Ecc, ix., p. 237), 

 1 -5mm. in length, 1-25111111. in width, oval, approaching circular in 

 outline, somewhat flattened on upper surface ; colour bright green, 

 becoming yellow-green as development proceeds ; surface faintly 

 reticulated, the reticulations much clearer towards the two ends, 

 especially the micropylar, which is somewhat broader than its 

 nadir. The micropylar depression is marked and the stellate 

 centre is discernible i/lAitt, July 9th, 1901. Eggs on Impatient). 

 The eggs are nearly spherical, but somewhat compressed, of a 

 grass-green colour, a little lighter and somewhat larger (1 -2111111.) 

 than those of Uyles euphorbiae. During the development of the 

 embryo the eggs first became yellowish-green and finally yellowish 

 (Weismann).
