On a small Collection of Lepidoptera sent from Nyasa in 

 1895 by Mr. R. Crawshoy. By ARTHUR G. BUTLER, 

 Ph.D. &c. 



ALTHOUGH the present consignment includes only one new 

 species, it is exceptionally interesting, not only as comprising 

 several links between described species, but on account of the 

 important additional evidence afforded by the careful dating of 

 the captures ; so that now it is possible, by comparing these 

 with Mr. Crawshay's previous consignments, to prove con- 

 clusively that several very distinct forms declared to be 

 seasonal and conspecific occur together repeatedly in various 

 months of the year that, in fact, they are not confined to any 

 particular season, and have no more evident claim to be called 

 forms of one species than our European Vanessa c~album or 

 V. polychloros have to be called forms of F. urticce* 



1. Melanitis leda, var. solandra.
