 a little broader. Underside of fore wing as in tessei, in some specimens 

 the white area more or less completely laved with yellow. Hind wing 

 with long subbasal streak, half white and half yellow as in tessei. The 

 discal patch more or less washed with straw-yellow. The red sub- 

 marginal line mostly with a narrow and straight costal spot and more 

 curved at vein 5. One specimen has the distal patch on the hind wing 

 sprinkled with orange-red scaling in the cell. 



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

 Kunupi, 6,000 feet, November to January. A series of both sexes, 

 mostly found on Mount Kunupi. 



18. Delias campbelli sp. nov. 



Distinct from any known form but apparently allied to hapalina 

 Jord., and distinguished by the black hind wing below. 



3 . Upperside almost as in hapalina, the distal black on the fore 

 wing broader apically, and with a straight edge from vein 2 to 6. 



Underside of fore wing with subapical yellow spots as in hapalina, 

 and distal black area as on upperside. Hind wing black. A subbasal 

 stripe of lemon colour (iv) larger than in hapalina. An apico-costal 

 triangular white patch between veins 6 and the margin, bordered 

 heavily with red on the inner edge. A little distad of the red edging 

 to the white patch is a thin red line from vein 6 to lb, curved out- 

 wards to vein 5, inwards to vein 2, and downwards to lb. 



? . Upperside of fore wing with much broader black, reaching end 

 of cell, or with a little white powdering outside in the cell. Hind wing 

 with broad black outer margin intermixed with white scaling and 

 inner edge nebulous. 



Underside of fore wing as above. Yellow subapical spots as in 3 . 

 Hind wing as in 3 , but the apical white patch reduced on its lower 

 edge, and more or less powdered with black. 



Length of fore wing, 3 27 mm., 2 28 mm. 



Menoo Eiver, 3,500 to 5,000 feet, November to January. A series of 

 both sexes. Mostly found at 4,000 feet, and rare at a higher elevation. 



19. Delias mariae J. and T. menooensis subsp. nov. 



Distinguished chiefly by the white area of the fore wing not being 

 clouded over.
