placed upright, with the micropyle at apex. The egg in about four days 

 turns deep yellow, inclining to a brownish tint. [Laid April 7th, 

 1897. Described on the 11th, from eggs obtained at Cannes.]— J. W.

Two INDEPENDENT DESCRIPTIONS OF EGOS OF ChESIAS RUFATA (oBLI- 



quaria). — The eggs are laid on the leaflets and flower-buds of Lieninta, 

 sp. ? singly, on their flat surfaces. The egg forms an almost perfectoval 

 in outline. Length : breadth : thickness : : 3 : 2 : 1, but slightly thicker 

 at the micropylar end than at its nadir. The colour is of a delicate 

 orange, approaching salmon colour. There is a large and rather deep 

 depression in the centre of the upper surface. The micropyle is placed 

 at the centre of one end, a small area being flattened, and slightly 

 depressed centrally. The shell is very faintly pitted, the edges of the 

 pits giving the surface a whitish and hoary appearance. [Described 

 under a f -lens, on July 7th, 1898, from eggs laid May 25th-27th, by 

 a $ taken at Wanstead ; received from Mr. Bacot.] Two eggs laid 

 loosely in a box by a captured $ ; the eggs themselves, however, 

 adherent to each other. Very pale yellow in colour ; and very small 

 for the size of the moth. May be said to be of ordinary Geometrid 

 form, oval, with a slight depression on upper surface, but bears a 

 distinct resemblance to an upright Acidaliid (or even a Pierid) egg. 

 The shell is apparently smooth, and under a low power (f-lens, used 

 as an eye-glass) no markings whatever are decipherable, but under a 

 more powerful lens a faint polygonal network is observable. The long 

 axis : width : height : : 7 : 3 : 2. [The eggs were laid on April 17th, 

 1898, by 5 taken at Cannes, and described the same day.] N.B. — 

 My two sketches of these eggs suggest considerable difl'erences, so 

 much so that one suspects a difterence of species. At any rate the 

 descriptions should be checked. — J. W. Tutt. 



Newly-formed pupa of Scoliopteryx libatrix. — On August 16th, 

 1901, I was fortunate enough to see a pupa of this species that had 

 just changed from the larval stage. All the appendages — legs, wings, 

 antennae, eyes, as well as the head and thoracic segments — were quite 

 bright pea-green. The pro- and metathorax quickly changed to a 

 brownish tint, the niesothorax also changing to the same tint dorsally. 

 The 1st to 7th abdominal segments were greenish-brown, the terminal 

 segments blackish. [This was from a larva taken, with several others, 

 near Villar, in the early part of the month.] — J. W. Tutt. 



Notes on Pyg^era pigra.^ — Owing to lack of careful observation 

 of the earliest stages of this moth, some rather grievous errors crept 

 into my former notes published in the Ent. Record, vol. xvi., p. 203. 

 Even these additional remarks on the subject are not fully satis- 

 factory, although rectifying several mistakes, and a careful study 

 of all the stages will be necessary in the spring to clear up the matter 

 finally. My inability to secure perfectly satisfactory results from the 

 second brood was due largely to the abnormal length of the pupal 

 period. In central Germany, P. pigra is normally double-brooded, the 

 second brood appearing in July and early August. As my first brood 

 had all pupated before the middle of June, I naturally looked for 

 emergences in July. However, with the exception of one or two 

 isolated specimens in the beginning of the month, nothing put in an 

 appearance, and that in spite of the intense heat. As by the middle 

 of August the pup» gave no sign of producing the imagines, I con- 

 cluded that the brood would pass the winter in this condition, and
