 series of 2 cJ cJ ami 113 '? ? from same locality, Jan. to 

 March 1014. 



The following three aberrational I'orms are contained iu 

 the series : — 



Milionia xanthica, ab. n'ujra. 



This form is representeil by a single ? , and differs in the 

 complete absence of the band on the fore wing above. Below 

 the band is wider than in the typical $ , but may be much 

 reduced, leading to the following form. 



Milionia xanthica, ab. hipuncla. (PI. XIL tig. 4.) 



The band on the fore wing is here reduced to two ill-defined 

 spots, one between veins 2 and 3 near tlieir base and a larger 

 one below it. These spots are better defined on the underside. 



This specimen shows an increase of black at apex of hind 

 wing, the spot on vein 7 being merged with the costal black. 



Type (a ? ) the oidy specimen. 



Milionia xanthica, ab. extensa. (PI. XIL fig. 5.) 



The band on the fore wing is much widened distally and 

 extends to upper margin of cell. Its outer edge is ill-defined, 

 and yellow scales are mixed with the groiuul-colour almost 

 to outer margin, the yellowish tini^e extending to vein 5 ; 

 this is much better defined below. The yellow of the hind 

 wing is more extended on both sides, so that the basal black 

 does not reach beyond middle of cell, and its edge is irregu- 

 larly defined. 



Type (a 9 ) the only specimen.
