342 Mr. H. Eltringham's iMonof/rajih of the 



extremely variable that it is not always easy to find two 

 examples exactly alike. 

 A. jolindoni f. conftma. 



F.-w. brown black. The pale spots as in typical form but 

 white. H.-w. as in typical form but basal patch pale ochreous. 



The 5 resembles the ^ . 



This is the commonest form of A. joltnstuni and it is rather 

 unfortunate that the previous form should have become the 

 type since it is in reality a rather rare variety. A variety of 

 the confitsa form has the h.-w. basal patch white as well as the 

 f.-w. spots. I have figured this form in Trans. Ent. Soc, pi. 1, 

 f. 13 (1911). , 



A. juhndoni f. fiavescens. 



In this form the f.-w. spots are pale ochreous the same as the 

 h.-w. patch. 



A. jolinMoai f. spmialliescois. 

 The f.-w. spots are white and the h.-w. patch is tawny yellow. 



A. jollllAtdnl f. flih'f.irc))^. 



The f.-w. is tawny yellow, the spots only a shade paler, and 

 there is a blackish apical and hind -marginal border. The 

 h.-w. is tawny yellow a little paler over the area wliich in 

 confusa is pale ochreous. A more or less well-defined but 

 narrov.- blackish hind-marginal border. 



A. ji)]tnsf(>ni f. (ictdhdJia. 



The spots of f.-w. and basal patch of h.-w. are tawny yellow 

 instead of white and pale ochreous. 



A . jolinstoni h}ifh'ri, su1)sp. 



Basal half of f.-w. purplish red with a slight blackish 

 sufl'usion at Ijase, beyond the red colour is a very irregular 

 band of rather tawny yellow its inner edge comparativel}' 

 straight as far as area 4, projecting sharply inwards in area 2, 

 and continued as a submarginal patch in llj and sometimes 

 also in la. Below area 3 the outer edge of this band is often 

 much suffused. Beyond the band the apex and hind margin 

 are brown black. H.-w. basal patch white to dull pink 

 followed by a broad blackish hind-marginal band. 



The tawny yellow band in the f.-w. of this form is so vari- 

 able in shape that it is not easy to find two examples alike. 



The 9 resembles the (^, but may be rather larger and less 

 richly coloured. 



The larva of A. jolinstoni has the body yellowish beneath 

 and brownish black above, each segment with a ring of
