something like that of a poppy-seed, with its promi- 

 nent ridges and irregular hexagonal pits (fig. 20S), 

 but there is not the dull opacity of the seed, and as 

 a type of insect eggs should have a place in every 

 cabinet. 



Fig. 209. Polyummatus Cnrydon. 



The Blues again afford another showy type of 

 egg, of which we figure that of Polyonimatus Corydou 

 (fig. 209). This egg is represented as seen from 

 above, and the prominent angles with hexagonal 

 pits present an elegant appearance, in fact the most 

 elegant of any here figured. Those of some other 

 Blues we have examined are very similar. 



These must suffice for the Butterflies, to which 

 we will add a selection from a long series of the 

 eggs of moths, kindly furnished by Mr. Norman, of 

 City Boad, who has given special attention to the 

 mounting of eggs of insects, as witness those of 

 parasites in a previous number of this Journal.

Fig. 210. The Buff Tip. 



The Buff Tip (Pt/ffcera bucephala) is a common 

 insect. The eggs are flattened spheres, covered 

 with a delicate minute tracery which scarcely de- 

 serves the name of markings. The base is quite 

 tUt and translucent, whilst the upper portion is of 

 a dull opaline or porcellanic whiteness. The surface

is probably glutinous at first, since small scales and 

 hairs are usually adherent. 



The Cabbage Moth (Mamestra brassicci) is only 

 too common. The eggs are nearly globose, with a 

 papillate apex (fig. 211). The longitudinal and 

 transverse ridges forming quadrilateral pits, which 

 arc more distinct than in the Cabbage butterfly. 



Fig. 212. The Willow Beauty. 



The Willow Beauty {Boarmia rliomboidaria) has 

 long cylindrical eggs with rounded ends, the surface 

 traversed by longitudinal ribs connected by trans- 

 verse ones which form irregular quadrilateral.ipits 

 or areolae. 



Fig. 213. The Canary Thorn. 



The Canary Thorn (Punomos tiliaria) has very 

 peculiar eggs of an angular form, nearly square at 

 the ends, with four parallel long ^rectangular sides. 

 The texture is delicate, of a rather clouded trans- 

 parency, faintly and minutely reticulated.

The Common Magpie Moth {Abraxas grosmla- 

 riata) has oblong eggs, which are hyaline and beau-
