with a flattened base, which admits of its being firmly 

 cemented to either bark or leaf. The egg is beautifully 

 reticulated, the ribs are slightly raised from the membrane, 

 and connected with each other by cross-bars ; they run from 

 a marginal ring in regular order to the base, and a series of 

 fine lines radiates from the central spot to the border. The 

 gg of the Pheosia dictcea, or Swallow-prominent (Fig. 4), is 

 spheroidal, slightly flattened at the poles, and, with the 

 exception of one spot, the surface is a continued series of 

 regular indentations, reminding one of those fine reticula- 

 tions, or markings, seen on some of the Guiano shells. The 

 colour is a very delicate pink. That of the Ennomos erosaria, 

 or Thorn moth (Fig. 5), is of an elongated square form, one 

 end of which is slightly tapered off, while the other is flat- 

 tened. The empty eggshell gives a fine opalescent play of 

 colours, while that containing the young worm appears of a 

 brownish yellow colour. The Diaerisia russula, or Buff- tiger 

 moth (Fig. 7), lays an exquisite little globular egg, the ex- 

 ternal membrane of which is covered by a fine network of 

 irregular hexagons. It has all the appearance of an irides- 

 cent minute glass globule, and is so translucent that the 

 young worm can be seen through it. The egg of the Erannis 

 defoliaria, or Mottled-umber moth (Fig. 8), is in every par- 

 ticular very beautiful. It is ovoid, with regular hexagonal 

 reticulations, each corner being studded with a white raised 

 knob or button. The space within the hexagon is 

 finely punctuated ; and the play of colours is exqui- 

 sitely delicate. That of the Hylopliila prasinana, or 

 small Silver-lines moth (Fig. 9), is yellow brown, in form a 

 truncated pyramid. A series of raised ribs are set in regular 

 order around the sides, and the cross-bars, which connect 

 them, presenting a pretty basket-like pattern. The egg is 

 flattened out at the base, apparently for the purpose of 

 securing it more firmly to the leaf. The Centra linula or 

 Puss moth (Fig. 10), lays a large spheroidal shaped egg, 

 having, under the microscope, the appearance of a fine ripe 

 orange. The surface of the egg is finely reticulated, or 

 rather has the appearance of a piece of netting stretched
