278 Mr. G. T. Betlmne-Baker's 



Anatossa, gaika, lysimon, mylica, lucida, atrigemmala 

 and unigemmata all belong to tlie Zizeeria group, and have 

 been most ably and effectively dealt with in the Trans- 

 actions of the Entomological Society of London, 1910, 

 p. 479, by my esteemed and much-missed friend, the late 

 Dr. Chapman. 



I figure (Plate XXV, fig. 63) the genitaha of Cafochrysojys 

 strabo to enable my readers to see the very marked differ- 

 ence in the whole formation of these organs, and I would 

 draw attention to the simple furca of this genus compared 

 with the much more extensive organ obtaining in Neo- 

 chryso'ps and its allies. Lycaenopsis (?) micyclns and 

 togara I also figure, to show that these are quite evidently 

 distinct species (Plate XXV, figs. 64 and 65). 



As is usual with this family, we have some range of 

 colour differences, blues of various shades toning down 

 almost into white. Browns in both sexes are not uncom- 

 mon; whilst there is one species, cupreiis Neave, which is 

 a very beautiful and unusual coppery brown with a fine 

 blue female. Sexual dimorphism is very rare in the group ; 

 in malatliana, in cupreus, in victoriae we find brown or 

 brownish males with blue femiales, the same also occurs 

 in necwei, but these with one or two more are quite 

 exceptional, the general characteristic being that both sexes 

 are more or less the same colour, though the area of blue 

 is less in the female than it is in the male ; and we have 

 no case at all in which the males are blue and the females 

 brown, a dimorphism that is very common in the palae- 

 arctic region and elsewhere. There are, however, several 

 species in which both sexes are brown. 



The androconia or battledore scales are interesting; 

 for species ranging so large in size as these do they are 

 very small indeed, there being only one species with these- 

 scales of any considerable dimension; they are of great 

 assistance in separating closely alHed species. I showed 

 some years ago (Trans. Ent. Soc. Lond., 1913, p. chx) 

 that androconia were not confined to species with blue 

 coloration, but that they also obtained in some quite 

 brown ones; this is confirmed by this genus, for all the 

 brown males with two or three exceptions have well- 

 marked androconia (battledore scales), whilst there is one 

 blue one that has none of them. These scales, however, 

 sometimes differ in development, and I have figured several 

 abnormal examples to show this process (Plate XXXII).
