The coloration of the wings in all three specimens is exactly as in de Meijere's 

 figure, and it seems to me quite probable that when the species of Psilopus are more 

 closely studied the difference in marking indicated by van der Wulp and de Meijere 

 will prove to be of specific value. Both these writers record the species from New 

 Guinea.

Eecorded by de Meijere from various localities in New Guinea. Walker's P. ex- 

 tendens, also recorded from New Guinea, is very similar, but is somewhat larger, the 

 dark markings on the wings are somewhat more extensive, and the front femora are 

 dark at the tip.

In this specimen the hind-femora and tibiae are entirely yellowish, except towards 

 the apex of the latter, which is dark. In Walker's type of P. henedictus (from 

 Waigiu) the hind-tibias are all black, while the type of P. persuadens (from Amboina)
