I have followed Kothschild in treating the form of machaon 

 found in the N.W. Himalayas as a race, and identical with var. 

 spliyms, Hiibuer = var. asiatica, Menetries, but as a matter of 



fact the variation in a 

 wide-ranging insect like 

 machaon is so great that 

 the description below 

 taken from Simla speci- 

 mens might well stand 

 for individuals procured 

 in the fens of Cambridge 

 or on the Continent. 



d 1 $ . Upperside : fore 

 wing dull black irrorated 

 on its basal third with 

 yellow scales, which also 

 form a transverse diffuse 

 postdiscal baud and a 

 diffuse prespical spot ; a 

 broad band across the 

 middle of the cell, another 

 narrower similar band at 

 its apex, a narrow streak 

 at base of interspace 9, a 

 quadrate spot near base 

 of interspace 8, a trans- 

 verse discal series of broad streaks that decrease in length 

 towards the costa in interspaces 1 a to 7, and a transverse 

 subtermiual series of crescentic spots, cream-yellow ; the streak 

 in interspace 7 with a superposed irregular diamond-shaped 

 black spot. Hind wing: the cell and broad streaks beyond, 

 divided only by the black veins and a narrow black edging to the 

 discccellulars, cream-yellow. These streaks are variable in length
