New Forms of the Genus Delias (Pieridae) 307 



discal series of intranervular streaks in le, 2, 3, 4 and 5, with some 

 faint yellow scaling on either side of them and a faint distal edging of 

 white, outlining a band which would occupy the same position as the 

 band found in jordani. A submarginal series of six yellow spots. 



Length of fore wing : 28 mm. 



A larger species than jordani. 



Menoo Valley, 6,000 to 8,000 feet, January, 1921, one $ . 



7. Delias cunningputi Eibbe, citrona subsp. nov. 



Allied to G. fascelis, Jordan, from Mount Goliath. Distinguished 

 by the yellow proximal area of both wings. 



S . Upperside of fore wing with basal area as in fascelis but citron- 

 yellow. Two subapical yellow dots. Hind wing with proximal area 

 citron-yellow and but slightly incurved between veins 4 and 6. Fringes 

 worn. 



Underside of fore wing as in fascelis, but the subapical spots darker 

 yellow, and discal shading yellowish and more extended. Hind wing 

 much as in fascelis. The postdiscal band is much broader both in its 

 yellow and white portions. Submarginal spots deeper yellow. Cellules 

 2 and 3 with yellow powdering between the band and submarginal spots. 



Menoo Valley, 3,500 to 5,000 feet, December and January, one <? . 



8. Delias microsticha Eoths. 



Nov. Zool. xi, p. 315, pi. 2, figs. 18, 19 (1904) (Aroa River). 



A series of this species was obtained in the Weyland Mountains, 

 between 3,500 and 6,000 feet, November to January. We have also 

 a specimen from the Wandammen Mountains, farther north, at 6,000 

 feet, November. 



It is interesting to note the great range of this form. The race 

 Ravopicta Jord., is confined to the Arfak Mountains. 



Two of the three female forms were obtained in the Weyland 

 Mountains, and specimens transitional to the other form with S -like 

 hind wing and yellow discal area on fore wing. 



9. Delias lecerfi sp. nov. 



This appears to possess no near ally, but may belong to the group 

 represented by aroae and phaeres. 



3 . Upperside of fore wing with basal two-thirds white, the outer 

 edge of this area curved inwards to costa at vein 6 and oblique from 6 

 to submedian. Hind wing white with a thin black marginal line. 

 Fringes black.
