The material consists for the European species, twelve specimens 

 (Germany, Austria, Switzerland, Alsace) especially selected for 

 the collection out of a very large number and representing all 

 varieties in size, color and pattern, which I was able to observe; 

 and one P. hospiton. The material for the Asiatic species (from 

 East India, Amballa, Koolloo, Himalaya, about 6000' high, Jal- 

 loree-pass, Himalaya, more than 10,000' high) thirty specimens 

 especially selected out of about 500 specimens as representing all 

 varieties. I possess only one male from Tokio, Japan. Finally 

 a couple collected by Mr. Chas. Wright at Owaska, Kamschatka, 

 probably fr. Wilkes' Exp. 



Exp. alar. 



European spec, male, 72 to 88 mm., female 82 to 92 mm. 



Asiatic spec, male, 72 to 96 mm.; female 78 to 96 mm. 



Kamschatka spec, male, ^2 mm.; female 84 mm. 



The tail of the hind wings. 



European spec, length 5^ to 9 mm.; breadth i to 13^ mm. 



Asiatic spec, length 5 to 10 mm.; breadth i to i^ mm. 



Kamschatka spec, length 5 mm.; breadth i mm. 



The main average of the size of P. machaon is smaller than in 

 P. 07'cgoniiLS and similar to P. Zolicaon, though there exist males 

 of P. oregonius of the same size of P. machaon. The tail of P. 

 oregonius is mostly broader, but not longer. 



The description of the var. ASIATICA Menetries quoted by 

 Mr. W. H. Edwards stated " the submarginal border of the 

 hind wings to be very broad, with the inner edge straight, 

 and reaching nearly the end of the cell." In my Asiatic 

 specimens this border is broad 4 to 7 mm., and in the Euro- 

 pean specimens 4 to 6 mm. The inner edge of the border 

 of the Asiatic is mostly less concave than in the European ones, 

 and exceptionally nearly straight ; others show the same curve 

 as the European ones. In specimens from Switzerland the inner 

 edge of the border goes as near to the cell as commonly in the 

 Asiatic ones ; and other Asiatic specimens show the cell even 

 more distant from the border as commonly as the European ones. 

 The final note by Menetries, "the marginal border of the Hima- 

 layan specimens is very much larger," belongs, apparently, to a 

 comparison with those of Kamschatka, as the words before the 

 N. B., " de r Himalaya et Kamschatka," prove. Indeed the lat- 

 ter have the marginal border of the male 2^ mm. broad, of 

 the female 4 mm. As the specimens from Himalaya and from 

 Kamschatka mentioned by Mr. W. H. Edwards were communi- 

 cated to him out of the collection of the museum, m}' remarks 

 cover the same specimens. 



The remark by Mr. Felder (Wien. Z. B. Gcs , IV., p. 363, Mr. 

 Edwards quotes the pamphlet edition, p. 75) " var. asiatica dis- 

 crepans alis adhuc brevioribus posticisque in regione anali magis 

 productis," is refuted by the measures given above. Mr. W. H.
