PIERIS CRATVEGI. Schrank. Steph. Kirby. 

 Black-veined White Butterfly. 



Wings rounded entire and white with the veins 

 black : the under side resembles the upper, except 

 that the black veins are somewhat stronger. The 

 caterpillar of this species feeds on the white thorn 

 but is not common. We have occasionally taken the 

 pupa? attached to this plant as represented beneath 

 the figure of the underside, (5-5) of this elegant spe- 

 cies ; and we have seen the perfect insect in some 

 profusion near Brockenhurst, in the new forest in 

 the month of June; and J. G. Children, Esq. has 

 received a great number of specimens from Wittlesea 

 mere. It appears that the caterpillar is occasionally 

 found on other trees, as Mr. Kirby says "in 1/91, in 

 some parts of Germany, they stripped the fruit-trees 

 in general of their foliage." 



At this season most of the garden species of white 

 butterflies make their appearance and the walks in 

 our garden on a fine morning will enable us to " ob- 

 serve the motions of that common white butterfly 

 which you see flying from herb to herb. You per- 

 ceive that it is not food she is in pursuit of; for flow- 

 ers have no attraction for her. Her object is the 

 discovery of a plant that will supply the sustenance 

 appropriated by Providence to her young, upon 

 which to deposit her eggs. Her own food has been 

 honey drawn from the nectary of a flower. This,
