Enprnctis chri/sorrhaa : The conspicuous egg batches of this species 

 are to be found on sea buckthorn, in July and August, in the form 

 of small bundles of brownish fluff wrapped around the twigs, the 

 eggs being completely covered with hairs from her anal tuft by the 

 parent insect. One of these bundles which I measured was fin. in 

 length and over |in. thick. When removed from the protecting 

 covering the ova will be found nearly globular, flattened at top and 

 bottom, and honey yellow in colour, with a smooth shell. Diameter 

 •8mm., and thickness -Gmm. 



Stil/motia salicis lays her ova in small batches on the bark of 

 poplars, enclosing them with some material having the appearance 

 of hard white froth. Patches of this may often be seen iin. long 

 and looking very conspicuous on the dark coloured bark. They 

 should be obtainable in July. The actual ova are globular, 

 flattened above and below, and olive-green in colour with a smooth 

 shell. Diameter -Qmm., and thickness -Smm. 



Malacoftnma nenstria oviposits in a highly specialized manner, the 

 ova being always found wild in the form of a ring or band about 

 fin. wide, encircling a small twig of hawthorn, sloe, plum, etc., 

 where the}' remain all the winter. They are cemented together 

 very firmly indeed, and can, with little trouble, be detached from 

 the twig and slipped off entire ; hence, no doubt, the rustic name 

 of " fairy rings " which has been given to them. 1 have seen a 

 batch around the stalk of a pear in a fruiterer's shop. The material 

 used to unite the ova is dark brown in colour, and is most difficult 

 to clear away for examination ; but, so far as I can make out, the 

 actual colour of the egg is a dirty white, with the micropylar area 

 lighter than the sides. In shape, they are flattened ovoid bodies, 

 with the micropylar end flattened. The shell is smooth, and has a 

 central depression containing the micropyle, this appearing to be 

 surrounded with a fine ring of darker colour. They are deposited 

 standing on their tails so to speak, the side of one egg being fixed 

 to that of the next, and all the micropylar ends, flattened and light- 

 coloured, facing outwards. In size they are l-2mm. long, -Smm. 

 wide, and -Tmm. in maximum thickness. 



Kriot/aster lanestris lays batches of eggs in March and April on 

 the higher twigs of hawthorn and sloe bushes, covering them com- 

 pletely with slatey-brown hairs from her anal tuft. They are not 

 placed in a compact mass, but often spread along and around the 

 twig for nearly a couple of inches. When separated from the mass 

 the ovum is found to be oval in shape, flattened on both sides, and
