02 SMALL WHITE. 



The caterpillar feeds on the cabbage, f Brassica oleracea.J 



The expanse of the wings varies from one inch and three- 

 qiiarters, to nearly two inches and a half: a singularly small 

 one, captured some years since, by my brother Frederick Philipse 

 Morris, Esq., is figured in the plate. The colour of this insect 

 is milk-white; the fore wings have a dusky or black mark, 

 irregularly defined at the tip, extending along part of the mar- 

 a-in ; and there is a black spot near the middle of the wing, and 

 a second indistinctly visible. The hind wings, have a dull dusky 

 black mark in a line Avith them, about the middle of the fore 

 edge. Underneath, the mark at the tip shews through, of a pale 

 yellowish colour, and there are two black spots near the centre; 

 in fact the same as those, one of which only is apparently visible 

 on the upper surface. The hind wings are yellowish, thickly 

 irrorated, principally near the base, Avith minute dots. 



The female has two black spots near the centre of the upper 

 side of the fore wings, and in many instances an elongated 

 patch of dusky black on the lower margin. There is a dull 

 black mark toward the centre of the fore margin of the hind 

 wings, in a line with the two on the upper wings. Sometimes 

 the whole upper surface is of a pale buff or yellowish colour. 



The eggs are placed singly. 



The caterpillar is pale green, with a narrow line of yellow 

 along the back, and an interrupted line of yclloAV on the loAver 

 part of each side. The head, feet, and tail are entirely green. 

 The body is slightly striated across with the segments. 



This is a most variable insect, especially in the size of the 

 sj)ots on the upper wings; in some, in flxct, they are wliolly 

 obliterated, and in others they are very large. I have a whole 

 row in my cabinet, no two of which are exactly alike. 



The figures are taken from some of them — one the singularly 

 small one already spoken of.
