PAPILIO.

centralis. In the course of his remarks on this variety Dr. Staudinger * 

 makes the astonishing statement that macilentus, Janson, is a form of 

 P. machaon. 



This species attains its maximum of size in the var. hippocrates, some 

 examples of which measure over 120 millim. in expanse. Dwarf specimens 

 are not of infrequent occurrence, and I have such examples from Kashmir 

 and China. 



Distribution. All the temperate parts of the Old World. In California it is 

 represented by P. zolicaon, Boisduval. 



Papilio podalirius.

" Diffcre de podalmus par Textension plus grande de toutcs les bandes ou flammes noires aux ailes 

 superieiircs en dessus. Do plus le trait fauve qui, a la face inferieure des seeondes ailes de 

 podalirius, descend du bord costal, a cote d'un trait blanchatre, entre deux lignes noires et 

 s'arrete a Fextremite de la cellule, est remplace dans podalirinus par una epaisse ligne 

 carmine, et cette ligne carmiuee est reproduite en dessus an milieu d'une bande uoire trcs 

 elargie. Le croissant fauve qui surmonte dans podalirius la taehe anale noire pupillee do 

 bleuatre, est remplace dans podalirinus par un croissant plus acccntue et egalement carmine. 



" Podalirinus est sans doute la forme thibetaine ([e podalirius." (OhertJiiir, I. c.) 



The Chinese form of P. j^odalirius, described by Oberthiir as above, differs 

 from the type in having all the transverse black streaks or bands on primaries 

 wider and more continuous and the central area of these wings suffused 

 with dusky ; on the secondaries there is a bright reddish band between the 

 central black streaks, and the lunule above the anal spot is of the same 

 colour. 



Appears to be very rare and local. M. Oberthiir's type was from Tse-kou, 

 and I have one example which was taken at a considerable elevation in the 

 neighbourhood of Ta-chien-lu. 



* " Die in letzteren beiden Gebieten vorkommenden Machaon-Formen sind zum Tlieil unter 

 eigenem Xamen bescbrieben und als verscbiedene Arten angesehen worden. So Macilentus Jans, 

 aus Japan, Oregonius aus Xordamerika etc. ; doch sind diese fast weniger von typiscben euro- 

 piiiscben Macbaon verscbicden als die vorliegende var. Centralis, die icb besonders aus der 

 TJmgegend von Margelan, abcr aucb aus der von Samarkand erbielt." (Staudinger, 1. c.)
