Delias hallstromi Sanford & Bennett, 1955

( Figs 19-22 )

Delias hallstromi is a common species in central PNG however the female is rarely encountered. Parsons (1998) illustrates a specimen in the ANIC from Marifunga in the Eastern Highlands. On Mt Hagen, females were frequently seen at locations 1 and 2 feeding on flowering plants. Individual variation is seen in the width of the discocellular bar on the forewing underside and the extent of white markings on the forewing upperside.
