throughout the distribution-area of this species: Europe, Central, West and North Asia, North Africa and 



the adjacent islands. However, certain districts (the higher mountains and higher latitudes) harbour special, 



endemic, forms: — intermedia Krulik., from South Russia, South Siberia, West Asia and the Altai Mts., intermedia.

of Asia Minor; the <f of the latter is rather more narrow-winged than napi-d'd', not bearing any markings 



on the forewing above except the blackish apical and basal areas; the ? has a yellowish ground-colour, 



which is however more or less suppressed by the great extent of the dark scaling situated along the veins. 



Among the ?? there occur specimens in which the discal spots and the vein-streaks of the forewing are 



strongly obsolescent, there being consequently no prominent marking; we name this form ab. obsoleta nor.; obsoleta.

As sabellicae >^teph. {= nigro-venosa iSr/z/.s) are to be regarded those sharply marked specimens in which sabellicae.

and again in August there flies in Tuscany meridionalis Riihl ; a larger form, less marked with black, the meridionalis.

orientis Oberth. (21d), from the Amur, Central China and the island of Askold, is much larger than orientis. 



European specimens; in the cf the hindwing beneath is not chrome-yellow but chamois-colour with a slight 



admixture of greenish; the ? resembles the bnjoniae-'i very closely, but the ground-colour is not yellowish 



but white. This butterfly is on the wing in May. — heptapotamica Krulik. is very similar to orientis, but hepta-

orientis; in cf the veins are broadly edged with greenish black beneath; it has not yet been ascertained if 



sifanica is really different from orientis. — The North American forms hukla Edw., from Alaska, and frigida 



Scudd., from Labrador, will be dealt with among the American Pierids. — Larva of najn dirty green, 



densely short-hairy, with a yellow stripe above the legs, small white tubercles and black dots, stigmata 



black edged with yellowish; feeds on cabbage and Reseda. Pupa greenish yellow, with black spots and 



dots. Egg pear-shaped, greenish, deposited singly. Appears in 2, sometimes 3 broods.

7. Genus: IJeilCOChloe Bober, gen. nor. 



This genus differs from Picris in the subcostal having 3 branches, from De/itis in 2 of tiiese veins 

 branching off proximaUy to the angle of cell and in the antennal club being nearly button-shaped. Only 

 2 Palaearctic species. — We find it necessary to introduce a new name for this genus. Type of the 

 Hiibnerian genus Synchloi-, in which genus dapJicide has hitherto been placed, is cidlidiee ; however, dup/idice 

 is not congeneric with that species. CJdoridice, which hitherto also stands in SijnMoe, doubtless also does 

 not belong there, agreeing in neuration much better with the genus EucJdoe.
