In last month’s 
coloured plate we 
gave pictures of 
the Small White 
(Pieris rape) and 
its larva and pupa. The female could be 
distinguished from the male by 
its two spots on the upper 
wing, while the latter has only 
one, and occasionally none at all. This 
month we are able to give a photograph 
(by Mr. Hugh Mair) of the Green-Veined 
White (Pieris napi) immediately after its 
emergence from the chrysalis stage. Like 
the small white, the male of the Pieris napi 
has only one round spot (instead of two as 
in the female) on the fore-wings. “The 
nervures on the upper wings are darker 
ordinarily, and the tip a stronger black in 
the female than in the male, but the 
strength of colouring varies very much in 
different individuals. It is an insect, too, 
that fluctuates a good deal in size; but, as a 
general rule, we find that the female is some- 
what larger than the male. The eggs are laid 
on cabbage, turnip, horse-radish, watercress, 
and other cruciferous plants, and the resulting 
caterpillars are of a delicate green colour. 
like those of the large white, they are

vigorously attacked by a special parasite, 
the Hemiteles melanarius. This butterfly is 
double-brooded, one generation appearing in 
April or May and another in July or August. 
They remain in the pupal state about three 
weeks before emergence. The specific name 
napt is bestowed on the species from the 
botanical name for the turnip, Brassica 
napus, one of the food-plants of the larvee. 
A variety of the green-veined white is 
sometimes found in which the colour of the 
wings, instead of being white at all, 1s of a 
beautiful canary colour, the veiming, soft 
shading, and definite spots and tips of the 
wings being, as normally, black. It is a 
very striking and beautiful form, and, 
entomologically, is the variety known as 
flava. We sometimes also get very dark 
forms and other modifications from type, 
such as the bryome, sabellice, and nape 
varieties: these were formerly given full 
specific rank, but are now accepted as being 
merely variants. Though called the green- 
veined white, the veining is often really 
grey. When the ground-colour of the wings 
is white the grey asserts itself; but this 
ground-colour varies a good deal, and when 
decidedly yellow the minute black scales 
that form the fringing of the nervures, 
blending with this yellow, appeal to the 
eye as green.’ —From “ Butterflies and Moths
