IQO LLOYD'S NATURAL HISTORY. 



of E. hesperidis are narrower and proportionately much longer 

 than those of E. cardamines, while the whole appearance of the 

 wing is much more even, and not nearly so rou^h as is the case 

 in the latter species." 



This form occurs in Surrey; Sussex; Church Stretton, Salop 

 (where Mr. Newnham finds it much rarer than E. cardainines 

 and apparently restricted to a small area), Llandago (common 

 and generally distributed : A. Nesbitt), Glamorganshire, Hasle- 

 mere, Pembroke, &c. 



Further observations are much needed to determine whether 

 tins insect has any real claim to be regarded as distinct from E. 

 cardamines or not. One point must not be overlooked. That 

 E. cardamines sometimes appears in a dwarf form in some 

 localities is certain ; and yet it is quite possible that E. hes- 

 peridis may be a distinct species, normally smaller than E. car- 

 damines. It would therefore be necessary, before attempting to 

 decide the point, to make sure that our specimens are really what 

 are called E. hesperidis^ and not simply dwarfed E. cardamines. 



Dr. Scudder proposes to restrict the name Anthocharis, 

 Boisduval, to the small American and Japanese group impro- 

 per y called Midea by Herrich-Schaffer. The two principal 

 species are A. genutia (Fabricius), from North America (the 

 type), and A. scolymus, Butler, from Japan. They are white 

 species, with an orange sub-apical spot on the fore-wings of the 

 male above, and the hind-wings marbled with green and white 

 beneath ; b it they differ from Euchloe in the longer fore-wings, 

 which are strongly po'nted at the tips.
