A. helvola: In my opinion this egg is alxolutt'ln different from 

 waeilenta, pisitacina, and circellaria. It is twice the size of uiac'dnita. 

 35 ribs, absolutely straight, very sharply raised, more so than vircel- 

 laris. Stellate area all but aljsent (or else (?) vertical on sides of 

 niicropyle) ; main ribs dip a great deal at this spot, but rise again and 

 run straight on to micropyle. Cross ribs very weak, straight, low, 

 more like the roof of a house than ribs. Micropyle very much raised 

 and fcrif irri/ small compared with inacilmta. But in spite of its small 

 size the micropyle has 20 (! !) pear-shaped depressions, which run in a 

 far steeper funnel to the centre. Length almost equal height : : 

 4 : 3i|. Colour yellow inside, mottled with red towards shell, specially 

 top half. 



Sminiiar!/. — The egg of A. jn'staciua is like, but far more degraded 

 than, > ). niacili'nta. M. cifccllaris is like, but slightly more specialised 

 than, (>. marilt'Hta. That of A. litnra seems a very elementary form. 

 A. Itiivola seems of quite a distinct class.

Eggs of Lepidoptera. — Callapliri/s riibi. — The egg is roughly 

 circular in outline and spheroidal in shape, being depressed or 

 fhittened at both poles ; the surface covered with a rather coarse net- 

 work that is roughly polygonal, the polygons having from five to nine 

 sides, although the greater number are hexagonal. The micropylar 

 ai-ea forms a comparatively large; depression at the apex, the sides of 

 the depression being much more finely reticulated than the remainder 

 of the egg, but still maintaining its polygonal character. The reticu- 

 lation, although irregular, suggests a certain amount of vertical ar- 

 rangement. The egg is uniformly green in colour, the ribbing paler, 

 somewhat transparent, glassy, almost silvery in hue. [Description 

 made on May 2Gth, from egg laid May 28rd, 1898, belonging to Mr. 

 I'^iler.]— J. W. TuTT. 



The eggs of Calloiihrys ruhi described above were laid on the petals 

 of Ult'.r furopat'ux, and on the leaves of Udianthoiiuiii luh/ari'. They 

 are globose, flattened ; the micropylar area depressed, covered with 

 reticulation of raised white lines ; the egg of a pale sea-green colour ; 

 diameter -Q^T to ^028 of an inch. In none of my specimens could 1 

 find the double white lines described ])v llcllins; the reticulation wa.-
