54 THE entomologist's record, 



notes were made : — The egg is roughly oval in outline, looked at 

 from above, inclining somewhat to brick-shape, owing to the square- 

 ness of the ends, the flattening of the sides, and the distinct oval 

 hollow that appears after a day or two on the upper face. The 

 micropylar end is larger, bulkier, much thicker, and more flattened 

 than its nadir, a character easily recognised when the egg is tilted 

 on another, and that, perhaps, gives the upper face of the egg the 

 appearance of sloping upwards from the nadir to the micropylar end 

 more than it really does. Although of a beautiful green when first 

 laid, these eggs rapidly become tinted with coral-colour, inclining later 

 to crimson, and, in a short time, assume a definitely bright pink-red 

 hue, these two colours being those which we associate with many pine- 

 feeding larvae and imagines resulting therefrom, and which, strangely 

 enough, are the colours of the two forms of the imago of the species 

 under consideration. The way in which the eggs are laid is very 

 interesting. They are placed closely together (end to end) in almost 

 straight lines from 6 to 12 in a line. Those most regularly laid are 

 tilted up at an angle of about 60°, the first laid flat or only showing 

 its natural slope, and then the thick micropylar end of each successive 

 one resting on the base (nadir) of its predecessor in the series, although, 

 in a few scattered examples, laid singly, a few of the eggs are almost 

 perpendicular, whilst one or two are almost flat. [Forwarded to Dr. 

 Chapman for further report on August 27th.] — J. W. Tutt. 



Gnophoii obfiiscata. — The eggs, which are green in colour when first 

 laid soon became dingy-brown to the naked eye. They are oval in 

 outline, length to breadth about 5 : 4, with one of the long sides 

 slightly depressed, and show all the characteristics of flat eggs, yet are 

 laid as upright ones, the micropyle at the apex, the attachment being 

 at its nadir. The sides are covered with a somewhat regular series of 

 shallow, longitudinal ribs, crossed by transverse ones, forming a sort 

 of ladder-like sculpture, reaching from the base to the sculpture, and 

 becoming modified over the apical area into a reticulation composed of 

 concentric series of cells surrounding the micropyle. After the egg has 

 changed colour the raised sculpture becomes shining-grey, through 

 which the reddish-purple tint of the egg shows, the apex being much 

 redder than the rest of the egg. [Eggs laid August 22nd, 1903, by a 

 $ taken at Chamonix on the preceding day, described August 28th. 1 —

Cossiix cosKiis {li<iinperda). — These are laid in four rough masses, 

 heaps or blobs of eggs, with a few scattered singly. They have 

 apparently been laid between the folds of a piece of stift' paper, and 

 are attached to one surface still. They are cemented together any- 

 how, side to side, end to end, end to side, etc., apparently in every 

 possible position. When laid singly they are on the side, but if, as I 

 surmise, they have been thrust into the crevices of folded paper, this 

 does not go for much in deciding if they are flat or upright ova. The 

 eggs are evidently laid soft and squeezed together, and are con- 

 sequently somewhat irregular as to outline ; but when not greatly 

 compressed, they show an ovoid outline on the long diameter, and a 

 circular or almost circular one on the shorter. The pointed end is 

 the micropylar one : the blunter, the base. They are, I should say, 

 upright or eggs of two diameters, and the position and character of 

 the ribbing suggests this also. Length, l-3mm., diameter, 1mm.,
