SEASONAL POLYMORPHISM. 141 



figured a female in Bho/i. Pal., pi. xxxii., fig. 20, under the name of 

 minima, Vrty., which I mention at p. 143. I used the same name at 

 p. 154 for tiny individuals of P. iiianni, Mayer, but these fall under 

 that of nana, Vrty., p. 166, and the name nrininia, first used for the 

 definite summer Beyrout generation of '^pi, should stand for the 

 latter. 



Summarising the conclusions of the above remarks, I find that the 

 seasonal and geographical variations of F. napi, L., in Europe, as far 

 as they are known to me, work out as follows : —

 the Alps and chiefly in the Eastern Alps. 



Race hryoniae, 0. : Single generation at very high altitudes in the 

 Alps. 



Race napaeae, Esper : I. gen. bryoniae, 0. ; II. gen. napaeae, Esp. 

 Described from high altitudes in the region of Geneva.

 in Central Europe.
