ZeGRIS — PlERIS. 7 



GENUS III. — ZEGRIS (RAMB.). 



Antennae very short, abdomen rather short and stout, thorax stout, very hairy ; pupae with 

 a short, obtuse spike in front, and a sort of arched tail behind. The only species is Z. EiipJieme 

 (Esp.), which is white, with a large black lunule at the end of the cell of the fore-wings, which 

 are green or grey at the tip, and marked with an oblong orange streak, bordered with black on 

 the inside. The hind-wings are yellow beneath, with greenish streaks, and several white spots. 

 Expands from li to if inches. It is common in meadows from April to June in Spain, South 

 Russia, and Asia Minor, but is always scarce in collections. Specimens from these different 

 localities vary a little, but are probably not distinct, though they have received different names. 

 The larva is yellow, with a white stripe and three rows of white spots on each side. It feeds on 

 Sinapis incana. 



GENUS IV. — PIERIS (SCHRANK). 



This genus contains the White Cabbage Butterflies, three species of which are abundant 

 everywhere. The antenna are rather long and slender, with a distinct knob at the end, and the 

 wings are white, with black tips and spots. The pup^ are not pointed. 



* I. P. Daplidice (Linn.), {Bath Wliitc). — Wings white above, with a large black spot in the 

 middle of the costa of the fore-wings, which are more or less bordered with blackish markings, 

 enclosing distinct white spots. The markings of the under side show slightly through on the 

 hind-wings, which have blackish marks near the edges in the female. The hind-wings are ^reen 

 beneath, with two rows of broad white spots beyond the middle and on the margin. It is found 

 in spring and autumn, the butterflies of the autumn brood being the largest and commonest. 

 Expands from li to 2 inches. It is common in most parts of South and Central Europe, North 

 Africa, and Western Asia, but is a great rarity in the south of England. In Germany I have 

 usually taken it in stubble fields in autumn, and its flight is low and heavy. The larva, which is 

 greyish-green, with yellow stripes on the back and sides, lives on cabbage, weld, &c., in June and 

 September. The butterfly is figured at PI. 4, Fig. 6. {P. Chloridice, Hubn., a scarce insect 

 found in various parts of Russia and Turkey, resembles this, but the dark markings on the hind 

 margin are much less extensive in both sexes, and there is much more white on the hind-wings 

 beneath.) 



2. P. Callidice (Esp.). — White, the hind margins more or less bordered with black, and a 

 black spot at the end of the discoidal cell of the fore-wings. Hind-wings green beneath, with 

 whitish spots shaped like arrow-heads. Size of Daplidice. Found in July and August on high 

 mountains, up to the snow-line along all the central ranges from the Pyrenees to the Himalaya. 

 Larva deep greyish-blue, with white stripes. Feeds on Alpine Critciferce in August and September. 



3. P. Krueperi (Stand.). — White, fore-wings with some black spots on the hind margin, a 

 black spot on the costa near the tip, and a second below it, at about half the breadth of the wing. 

 Hind-wings with a black spot on the costa. Under side of fore-wings white, yellowish at the 

 tip, with only the two spots marked : the first is greenish, and the second black, larger than 

 above. Under side of hind-wings dull green, with the outer third of the wing and a very large 

 blotch near the costa paler. Expands 2 inches. It inhabits the mountains of Greece and Asia 

 Minor. It is not a variety of the Indian P. Canidia (Sparrm.), as some writers have supposed. 



*4. P. Napi (Linn.), [Grcen-veiiicd White). — White, fore-wings with the tip dusky, and with 

 one black spot in the male, and two, and a black dash on the inner margin, in the female. 

 Hind-wings with a spot on the costa above ; beneath yellowish, with very broad greenish veins. 

 Expands from lA to 2 inches. Common from April to August throughout Europe and Northern
