166 THE ENTOMOLOGIST. 



submitted to the late Mr. Birchall, who decided that they were 

 not minos ; but he was unable to say what they were. Cornwall 

 would, however, be a very probable locality for the insect to be 

 found ; but we are not aware that the matter has yet been 

 investigated. 



Among the species casually taken in England is Sijntomis 

 jjliegea. It is a Mediterranean species, extremely local in Central 

 Europe north of the Alps, though it may be extending its range 

 in that direction. Being a gregarious day-flying species, found 

 setthng on tall flowers, or flying about bushes, the specimens 

 taken singly in England can only have been casual importations. 



Callimorpha HERA. — Tliis species is probably a recent intro- 

 duction to the country. It is a day-flying moth, long known as 

 an inhabitant of the Channel Islands, and latterly found in some 

 quantity in Devonshire. Entomologists, unlike botanists, do not 

 recognise the Channel Islands as part of the British Islands, and 

 hence this species had to wait its turn to take its place in our 

 British list^. 



Deiopeia pulchella. — The comparatively large number of 

 specimens of this species which have been taken in England of 

 late years, as compared with its former excessive rarity as a 

 British species, illustrates the present tendency of the Medi- 

 terranean fauna to extend its limits northwards along the coasts 

 of Western Europe. D.]jidchella is an almost ubiquitous species 

 in the warmer parts of the Old World. 



ON THE REARRANGEMENT OF THE FABRICIAN GENUS 

 COLIAS, AND THE PROPOSAL OF A NEW GENUS 

 OF PIERINiE. 



By John Watson. 



The secondary sexual characters of Rhopalocera have always 

 been of the utmost importance in classification, possessing as 

 they do such constant lines of demarcation of genera, and being 

 as constant as any system of classification based upon neuration 

 alone ; and though I do not wish it to be thought I desire to extol 

 an arrangement based upon these characters alone, above one on 

 neuration, yet at the same time the consistency of such an 

 arrangement is undoubted, and more particularly where it 

 applies to such a heteromorphic collection of species as are at 

 present included in the Fabrician genus Colias. 



This fact has never been brought home to me more forcibly 

 than when checking my arrangement of this genus with that of 

 Mr. Kirby's ' Catalogue of Diurnal Lepidoptera ' ; and a careful 

 examination of my own and other collections of palaearctic 

 Bhopalocera brings me to the conchision that the assemblage of
