New Forms of the Genus Delias (Pieridae) 309 



veins 2 and 3, and further indicated by a yellow streak in lc. Marginal 

 yellow spots smaller and absent before vein 2. 



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

 Kunupi, 6,000 feet, November to December ; Djalan Eiver, May and 

 June. A series of 3 3 and a small series of both ? forms from 

 Menoo Kiver and Mount Kunupi. 



11. Delias phaeres Jord. approximata subsp. nov. and ? f. rectimargo 

 f. nov. 



This species was regarded by Dr. Jordan (Nov. Zool. xviii, p. 588, 

 1911), as a race of aroae, which was a quite justifiable conclusion upon 

 the evidence then available. We have however received a race of 

 aroae from the same locality as phaeres, and these must be treated 

 now as distinct species, although they are remarkably alike. The 

 present race presents some of the characters of aroae, but is distin- 

 guished by the extension of the black distal area of the forewing to 

 the discocellulars on the upper side and into the cell on the underside. 



3 . Upperside of fore wing with the black entering the end of the 

 cell but slightly, and mostly bordered by the discocellulars. The white 

 patch in 3 mostly larger than in the type form. Hind wing as in the 

 typical form. 



Underside of fore wing with a white cell-stripe as in aroae and not 

 reaching the discocellulars. The white area in 3 larger than in the 

 type form, and the black distal margin narrower on veins 2 and 3. 

 Hind wing with discal band a little broader than in type form. 



? . There are two forms as in aroae, and these present similar 

 characteristics. The typical form differs on the fore wing above and 

 below in the extended white area as in the 3 , and the hind wing is 

 similar to the 3 . 



2 f. rectimargo. Similar to the form brevifascia of aroae, but pre- 

 sents the characteristic broad black margins of phaeres. Underside 

 of hind wing with discal band reaching lc, where it is greatly narrower. 

 Marginal spots small. 



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

 Kunupi, 6,000 feet, November to January. A series of 3 3 , a small 

 series of typical 5 ? , and three specimens of /. rectimargo. 



12. Delias nais Jord. 



Nov. Zool., xviii, p. 587 (1911) (Mount Goliath). 



This species was fairly plentiful on the Menoo Eiver and Mount
