104 Mr. H. Eltiinghatn's Mono(jraiih of the 



serrated though this is largely due to the depth of the white 

 internervular fringes. The discal spots of h.-w. are well 

 developed and the ground-colour tends to invade the niarginnl 

 black along the nervules. 



A. adriycra, f. hrunnea. PI. I, f. 4 ( ^^ ), f. 3(9). 



The rosy red and orange of the astrigera form is here replaced 

 by dull brownish oclireous, and the two sexes are alike in colour. 

 In Angola examples there is sometimes a more or less distinct 

 white subapical bar on the uj^perside of the f.-w. The f.-w. 

 apical and hind-marginal black may be broader, suffused, and 

 bear marginal yellowish marks. H.-w. discal spots often larger 

 than in typical form. 



It is not without mucli consideration that I have arrived 



at the conclusions embodied in the above synonymy. 



Isolated examples of tlie different forms Avould provide 



comparatively little evidence of specific identit}^, but I have 



been fortunate enough to secure from various sources a 



fine series numbering between thirty and forty examples, 



the localities ranging from German E. Africa to Angola. 



There are males and females of each furm (except f. emini), 



and a series of preparations of the genitalia shows no 



differences of structure. Weymer assumed that his Acraea 



emini Avas a ^, though owing to the imperfection of the 



specimen he was unable definitely to decide. It is larger, 



a little brighter in colour than the ordinary ^ of the form 



astrigera, and has more rounded wings, but cannot be 



specifically separated. Moreover I have before me a $ 



which agrees precisely in shape, depth of colour, and in 



every detail of pattern with Weymer's description and 



figure of Acraea emini. This specimen is accompanied 



by two ^ $ which, except for a slight difference in depth 



of tint of the ground-colour, agree precisely with astrigera. 



Suffert, on the assumption that Weymer's specimen was 



a male, recorded (/. c.) an example of the female which he 



described as very similar to the supposed male. From 



these facts I conclude that Weymer's A. emini is a female, 



anil further that it is a ^ form oi psendoli/eia astrigera. 



An examination of the dates borne by examples before 

 me shows that the different forms are not seasonal. The 

 geographical distribution is somewhat peculiar. The 

 red and orange form seems only to occur at the eastern 

 end of the ranp-e of the species, but it is accompanied
