19. Delias albertisi discus Hour. 



Delias discus Hoiirath, Bed. Ent. Zeitschr. xxx. p. 1.30, t. 5, f. i (1886) (Sekar). 



As neither Oberthiir nor Hom-ath stated the sex of their types, D. discus was for many 

 years put down as the ? of D. albertisi Oberth. When, however, 1 received the large 

 cries collected by A. S. Meek on the Setekwa River we at once saw that this was not 

 the case. There are in reality 3 distinct local races of this insect : albertisi albertisi 

 from Arfak Peninsula with entirely black forewings above ; albertisi neyi from British 

 New Guinea with the basal ^ of forewing white ; and albertisi discus with from \ to f 

 of the forewing white. Below, the black patch in the disc of the hindwing is, though 

 variable, largest in a. discus, medium size in a. albertisi, while in a. neyi it is reduced 

 to a dot or entirely absent. The sex of both Oberthiir 's albertisi and Honrath's discus 

 is female, while Sir George Kenrick has described the S of albertisi, though unfortu- 

 nately giving it a new name, africanus.
