Pierine Butterflies of the Genus Delias. 147 



whitish and small (female figured by von Mitis, Taf. ii. fig. 5, 

 as D. mindanaensis ?). Luzon. 



3. Secondaries with fewer scarlet spots two to three in 

 male, three large and two very small in female (male D. min- 

 danaensis, fig. 4). Mindanao. 



4. Apex of primaries above crossed by more or less con- 

 fluent broad white streaks, forming a belt crossed by black 

 veins; secondaries below with six scarlet spots. D. pala- 

 wanica, Palawan. 



5. Secondaries below with second and third spots small 

 and whitish. Mindoro. 



That any of these forms is constant to locality may be 

 doubted.

c?. Upperside resembling D. Stollii (autonoe, Stoll, not

 white, with black veins slightly expanded on the outer border 

 of the primaries, and so much so on the secondaries as to 

 form a continuous narrow sinuated border ; internal third of 

 secondaries pale chrome-yellow ; no red submarginal spots.

Six examples, of which two were in the Godman and Salvin 

 collection ; the species is easily recognizable by the second- 

 aries on the under surface being almost wholly yellow, 

 combined with very small scarlet submarginal spots, bordered 

 externally by a yellow edging, which separates them from 

 the black of the outer border.
