There is considerable difference in size, and, in series, the $ s look 

 distinctly smaller than the $ s, and the very high mountain specimens 

 less than those of the lowlands ; often the size is indicative of race, as 

 noted in our account of var. array emends and var. hispana, and one 

 observes that the very high mountain race of the Hautes- and Basses- 

 Alpes, from Abries, Larche, etc., averages only 35-5mm., whilst the race 

 from Bourg St. Maurice averages fully 42mm., some c? s reaching 46mm. 

 Our $ s from the Saleve measure from 37mm. -40mm., and the £s 

 35*lmm.-37 , 5mm., $ s from Useigne 46mm., 5 s from Berisal, Col de 

 Forclaz, Saas-Fee 40mm., and from Weesen Marsh 41mm. Blachier 

 notes the largest $ that he has from the Geneva dist. as 42mm., and 

 the largest 2 40mm. Occasional large examples come from most 

 lowland localities, e.g., Bourg d'Oisans 44mm., Clelles 44mm., Gresy- 

 sur-Aix 44mm., Digne 42mm., Fontainebleau 42mm., Bourg St. 

 Maurice 46mm., Val Anzasca 44mm., whilst an example of albicans 

 (from Granada) reaches 48mm., a $ arragonensis (from Albarracin) 

 46mm., a $ caticasica 44mm. Our largest $ albicans measures 42mm., 

 a large 2 from Gex 40mm., from Digne 41mm., from Bourg St. 

 Maurice 40mm., from Fontainebleau 42mm., from Trafoi (several) 

 40mm. -42mm., San Salvatore, 42mm. Anything above 40mm. should 

 be considered ab. major. Occasional small examples of both sexes 

 appear to occur almost anywhere, and those below 30mm. look exceed- 

 ingly tiny. We have a $ from Clelles 29mm., another from above 

 Pre St. Didier 27mm., from Courmayeur 27mm., Val Bigontina 29mm., 

 etc. Blachier records both $ s and ? s of 30mm. expanse from Valais, 

 Val Maggia, Versoix, Simplon, Val Anzasca, and the Saleve, all 

 districts that usually produce well-developed examples. Reverdin notes 

 his smallest $ as coming from Brides-les-Bains, and $ from 

 Saas-Fee. Anything below 32mm. is certainly ab. minor. Pickett 

 has, in his collection, a considerable number of both sexes (from near 

 Dover) below 30mm., and some $ s under 25mm. (measured from
