330 THE YOUNG 



COLIAS HYALE. 

 The Pale Clouded Yellow. — An 

 insect of very irregular and uncertain 

 appearance. Probably only occurs 

 here when a migratory swarm or part 

 of one has reached our shores. When 

 it does occur it is found in the more 

 southern counties, and never strays 

 northward beyond the midlands. 



COLIAS EDUSA. 



The Clouded Yellow. — Much 

 more frequent in appearance than the 

 last^ but equally irregular, and it is 

 probable that this species only keeps 

 its place by immigration. Sometimes 

 it is exceedingly abundant, and though 

 always more abundant in the south, it 

 occasionally, as in 1877, strays far 

 north, and even reaches Scotland. The 

 perfect insect hybernates, but a second 

 brood sometimes occurs. 



ANTHOCAEIS CARDAMIlNES. 



The OiiANGE Tip. — A common but- 

 terfly in almost all parts of the country, 

 appearing in the early part of May in 

 the south and rather later further 

 north. The female is rarer than the 

 male, and is without the orange patch 

 at the tip of the fore wings. It may 

 often be found at rest on -umbelliferous 

 flowers, and the resemblance between 

 the underside of the hind wings and 

 the umbelliferse on which it rests, will 

 strike the least observant. The larva 

 feeds on Cuckoo flower [Cardamine pra- 

 tense)i called also milkmaid " in some 

 places ; on Hedge mustard {Sisi/m-

hrium alliaria), &c. The pupa is long, 

 slender, and much curved, and remains 

 over the winter.

 The birds composing this genus are all of 

 moderate size. The beak rather large, upper
