racters of these disputed forms, without venturing to pronounce 

 any opinion of my own. 



L. Shiapis (L.) White, with an ash-coloured apical blotch 

 reaching quite to the tip of the fore-wing: hind-wings beneath 

 with extensive dusky green markings. 



L. Diniensis (Bd.) Differs from Sinapis in the apical blotch 

 not extending to the tip of the fore-wing : the hind-wings are 

 almost immaculate beneath. Occurs in England and France. 



L. Erys'imi (Bkh.) This form, which is now allowed on all 

 hands to be a variety, is entirely without the apical blotch. Same 

 localities. 



L. Lathyri (Hiib.) Differs from all the rest in the base of the 

 wings being yellowish. Underside of the hind-wings greenish, 

 with two white spots. Occurs in France and Germany. 



L. Amurensis (Men.) Differs from the other forms in the 

 shape of the wings, which are less rounded, and in other minor 

 particulars. This form replaces Sinapis in the more southern 

 parts of Amoorland, and I believe is also met with in Europe. 



Genus Colias. 



A genus of moderate size, the species of which have generally 

 a very wide range, and are most frequent in the north temperate 

 zone. C Palceno and Phicomone occur in the mountains of 

 South Europe : but their polar sub-species are common to Lap- 

 land, Siberia and Labrador. C. Edusa ranges from England 

 throughout Asia, and occurs in North America. C. Chrysotheme 

 occurs in Eastern Europe and North America, but Boisduval 

 doubts whether the American specimens are not distinct. Me- 

 netries also gives Irkutsk as a locality for this insect. C. Hyale 

 is a more widely dispersed species than any we have yet noticed. 

 It is met with from North Russia to the Cape of Good Hope, and 

 from England to Siberia and California. 



Genus GoNEPTERYX. 



G. Rhamni ranges eastwards to Amoorland and California. 



Genus Danais. 

 The only European species of this Indian group is Danais 

 Chrysippus, which occurs all over Africa, India and South China. 

 In Europe it only occurs in Greece and Turkey. 



Genus MeliTjEA. 

 This genus appears not to occur in South Africa; and if any
