" Hose and black white-tailed Fritillary " (R. C). 



This form varies, not only in the width of the black apical 

 patch of pi-imaries, the position of the second spot of the central 

 transverse series, the width of the black border of the secontlaries 

 with its more or less detlned submarginal spots, but, curiously 

 enough, the terminal two-fifths of the abdomen may be either 

 ochreous or snow-white. As in the variety axina ( J , nero) the 

 submarginal spots of the primaries are wanting. The specimen 

 now received bears a strong general resemblance to A. natalica. 



In his paper, published in the 'Proceedings' for 1891, Mr. 

 Triiuen lays stress upon the absence of the submarginal spots 

 as a good character for the discrimination of A. axina fi*om 

 A. douhledaiji : I am sure that his earlier decision was the correct 

 one, and that this character cannot be relied upon ; in A. cceciliu, 

 var. sfenobcea ( 2 ^=li(/tis = albomaculala) the submarginal spots are 

 sometimes present, sometimes absent \

With our present e.xteusive series it is impossible to keep 

 A. pseudegina distinct from A. natalica, oP which it is only the 

 Western phase, the two extremes are completely linked by inter- 

 grades.

1 gave the correct synonymy of this species (if species it be) in 

 the ' Proceedings ' for 1893, p. (557. I, however, strougly suspect 

 it to be merely a seasoaal development of A. cmcilia, var. slenobma, 

 from which it chiefly differs in the broad black apical patch on 

 the primaries.

 confirmed by Prof. Aurivillius duriug his recent visit (Aug. 1895).
