312 Neiv Forms of the Genus Delias (Pieridae) 



16. Delias hypomelas Jord. rubrostriata subsp. nov. 



This form is distinguished from hypomelas hypomelas Jord., and 

 from h. conversa Jord., by the red streaks on the hind wing below. 



3 . Upperside as in conversa, the black margin of the hind wing 

 a little wider between veins 4 and 6. 



Underside of fore wing as in the other forms. The black post- 

 cellular shade more as in the type form and not reaching below vein 4. 

 The white inner margin does not extend above the submedian except 

 for some scattered white scales in some specimens. Hind wing with 

 ground-colour as in the other forms. Postoellular black spot smaller 

 than in conversa and more as in the type form, between vein 4 and not 

 quite to vein 6, and more or less extending into the cell where it joins 

 a more or less defined black cell-streak. The cell-streak forms an ovate 

 spot in the cell, scaled with red. White marginal spots as in the other 

 forms. Streaks of nopal red (i) on a black ground in cellules lc, 2, 3, 

 4, 5, 6 and 7, those in 4 and 5 short and indistinct, the one in 7 the 

 longer and most heavily marked. In some specimens the red streaks 

 are reduced to some scattered red scaling, and in all worn specimens 

 they are obsolete. It seems that these red scales are easily lost and 

 may represent quite a recent development in comparison with the other 

 markings. 



? . Upperside as in conversa but with a distinct yellow tinge on the 

 inner margin of hind wing. Underside as in the $ , but the white 

 inner margin of fore wing broader as in conversa S . 



Menoo Eiver, 3,500 to 5,000 feet, November to January ; Mount 

 Kunupi, 6,000 feet, November to December — a series from both. Types 

 from Mount Kunupi. 



17. Delias hapalina Jord. conspectirubra subsp. nov. 



This race approaches tessei J. and T. from the Wandammen Moun- 

 tains, but the distal black area on the fore wing is much more extended. 



? . Upperside of fore wing with black area reaching to just before 

 the discocellulars. Hind wing as in the other races. 



Underside of fore wing with broader black than in the other races, 

 and edge of white area only reaching vein 6. Hind wing with the 

 black band thicker than in the type form and less wide than in tessei. 

 The postdiscal part of this band not edged with red or only very slightly 

 so, the red spot always present in lc. The black marginal border 

 reaching to the fold in cellule 3, narrower than in tessei. In a few 

 specimens the postdiscal black line is narrower than in the type
