THE YOUNG NATURALIST. 



Pieris Brassioe. — Mr. Gregson has a very curious example of this 

 species with the veins in the middle of the hind wing distinctly green, making 

 it appear to be streaked with that colour. This is believed to be caused by 

 a rupture of the veins ere they have stiffened. I have a specimen in bad 

 condition, with the margins of the hind wings blotched with green and doubt- 

 less from the same cause. 



Pieris Rap^e. — No varieties of note, but Mr. Gregson has one expanding 

 just over an inch. 



Pieris Napi. — Of this species he has a still smaller specimen, and Mr. 

 Capper has a very extraordinary example, in which the ground colour, instead 

 of being greenish white as usual, is ochreous yellow, not unlike the hue some- 

 times assumed by Eapa, but of a deeper shade. 



Anthocaris Cardamines. — Besides a hermaphodite, with the orange 

 patch on one side only, and a female with a streak of orange on the right 

 forewing, Mr. Gregson has one a rather bright yellow over all the wings, like 

 the continental Eupheno or Euphenoides. Mr. Capper also has a male, with 

 the patch on forewing, a pale yellow instead of orange, another without the 

 black disc spot, and a third with the disc spot very large. 



Leucophasia Sinapis. — Mr. Gregson has some very fine examples of the 

 var., Diniensis, in which the tip blotch does not reach the margin of the 

 wing ; also var. Erysimi entirely without the blotch. 



Gonepteryx Rhamni. — A very curious aberration with a bright carmine 

 streak on the wing is in Mr. Gregson' s collection. 



Colias Edusa. — The best variety of this species Mr. Gregson has, is one 

 with an unusually broad black border, the inner edge of which gives a toler- 

 ably correct outline of the face of King George the Third, Mr. Gregson, 

 therefore, calls it "Le Roi." Mr. Capper has a specimen intermediate 

 between the well-known variety Helice, and the type. 



Colias Hyalk. — This is a very constant species. Mr. Gregson's collec- 

 tion has one with the black at the tip of the fore-wing much less extensive 

 than usual. 



Thecla Rubi. — The genus Tkecla does not afford much scope for varia- 

 tion. Mr. Gregson has the only example I have seen, a specimen of Rubi 

 with pale blotches on the wing. These are not alike on both sides, and 

 probably result from the same cause, whatever it may be, as the well known 

 pale blotches on Janira. 



Polyommatus Phl;Eas. — Half-a-dozen var. Schmidtii grace this collection. 

 Two others with fore-wings silvery, and one with only one wing white are 

 still more interesting. These he calls var. Semi- Schmidtii. Dark suffused
