New Forms of the Genus Delias (Pieridae) 315 



Mount Kunupi, 6,000 feet, November to January ; Menoo River, 

 3,500 to 8,000 feet, November to January. A small series of both sexes. 



21. Delias marg'uerita sp. nov. 



Quite distinct from any known form but probably allied to alepa 

 Jord. 



3 . Upperside almost exactly as in ale-pa Jord., the black marginal 

 line of the hind wing being broader than in alepa alepa and just as 

 in alepa hunupiensis. 



Underside of fore wing as in alepa alepa except that the subapical 

 spots are much larger in cellules 4 and 5. Hind wing with the red 

 subbasal stripe shortened distally and the space between it and vein 8 

 filled in by a white stripe reaching to just before the end of vein 8. The 

 red stripe is not of the same red tone as in alepa, but is nopal red (i). 

 There is a narrower stripe of the same colour in lc from below cell 

 at base to the postdiscal line, and partly represented in phippsi by an 

 oblong spot. Cellule lb is filled in with pale olive-grey (1) from base 

 to marginal line, and la is ecru-olive (xxx). The outer edge of the red 

 stripe is narrowly edged with black to a variable degree, the red scales 

 overlaying a black ground. At the distal end of the stripe this black 

 scaling becomes broader and bends at right angles to form a postdiscal 

 line, which is nearest the cell on vein 3 and does not generally reach 

 vein 4. This line varies in w T idth, becomes thinner anteriorly and in 

 one specimen reaches vein 5, by a distal curve. The outer edge of the 

 postdiscal band is bordered with red which continues as a thin sub- 

 marginal line from vein 4 to just before vein 7, being parallel to the 

 margin from below vein 5 to its termination. The basal area between 

 lower edge of cell and middle of costa and discally to vein 7 is black ; 

 this area is continuous with the black scaling in lc, and postdiscal band. 

 Discal area of wing within postdiscal band laved with straw-yellow. A 

 marginal black border as on the upperside. 



Length of fore wing : 23 mm. 



Menoo Eiver, 4,000 feet, December to January, twelve 3 3 . 



All taken at one spot within a few days. 



22. Delias phippsi sp. nov. 



Allied to alepa Jord., but very distinct. 



3 . Upperside of fore wing with black distal area extending along 

 costa to base, to the discocellulars, to vein 4 before its middle and 

 obliquely to the end of 2. Hind wing with black marginal border about
