836 THE ENTOMOLOaiST's RKCORD. 



SyrichtliKs alveus. — Base quite flattened ; shape about three-fourths 

 of a sphere, somewhat flattened at the apex ; pale yellowish in colour, with 

 the slightest possible green tinge ; with 22 longitudinal ribs reaching 

 from base to apical area, 7 pairs anastomosing just above the shoulder 

 of the egs,, the ribs somewhat acutely-edged, but showing distinctly 

 the very numerous fine transverse ridges that surround the egg from 

 the base to the edge of the apical area. This latter consists of a well- 

 marked but iTiinute circular depression within the terminations of the 

 longitudinal ribs ; medially in this there is a distinct raised micro- 

 pylar stella. [Eggs described August 18th, 1903, dissected from a ? 

 captured at Chamonix the same day.] 



Paniphila cniiima. — The egg is hardly more than a hemisphere, the 

 base quite flattened, the apical area depressed, the micropyle forming 

 a raised point in the centre of the depression ; the colour is, when 

 newly exposed, pearly-white, but it changes almost directly to a 

 shining chalky- white, the apical depression alone retaining the paler 

 coloration. The whole of the surface of the egg is minutely pitted, 

 and, under a lens, has the look and apparent texture of the shell of a 

 hen's egg. There is no trace whatever of longitudinal or transverse 

 ribbing, and the egg is as dissimilar as possible from that of the well- 

 ribbed egg of Si/richtJiiix alreux, with which it was compared. [Eggs 

 described August 18th, 1903, dissected from a $ , captured at 

 Chamonix the same day.] 



Lithmia luridcola. — The egg is of a pale pearly-yellow when laid, 

 becoming of a more or less transparent pearly-grey as the embryo is 

 matured ; it is almost hemispherical in shape, the surface shining and 

 somewhat iridescent, with a suspicion of minute surface pitting, under 

 an ordinary hand lens. No trace of the micropylar structure can be 

 discerned with the power at disposal. The eggs are laid in little 

 batches side by side, and touching each other. [The eggs described 

 on August 10th, were laid in the collecting-box by a $ obtained at 

 Useigne on July 28th, 1903, and described August 10th. j 



Litluma lutarella (the typical golden -coloured mountain form). — 

 Pale pinkish or flesh-coloured in tint, rather more than a hemisphere 

 in shape ; what should be normally the base occupied by a deep 

 circular depression, which appears to have the same kind of surface 

 structure as the rest of the egg ; this surface-sculpture appears to 

 consist (under power at disposal) of exceedingly tine pits (it might be 

 an exceedingly delicate reticulation under a higher power), but I am 

 not able to make out any ribbing. The surface is exceedingly shiny, 

 and the bright areas (due to reflected light) obscure any minor detail 

 that may be present. ,1 was astonished to find that the eggs were 

 laid loosely, although having the characteristic shape and appearance 

 of the allied eggs that are attached. Those described were laid by a 

 5 captured at Hauderes on July 29th, 1903, in cop., which laid during 

 the following days a few eggs each day, up to and including August 

 11th, when the ? still appears to be lively and healthy, and capable 

 of laying many more eggs. The description was made on August 7th.] 



(K)iistis (jHodra. — The eggs are laid most regularly side by side in 

 large batches. The eggs are exceedingly small for the size of the 

 moth, and of a pale pea-green colour. The egg is somewhat less than 

 a hemisphere, considerably flattened at and towards the apex, covered 

 over with small but conspicuous pittings. The micropylar point
