Utakwa River ; numerous female specimens. 



A series was taken showing considerable variation in colouring and in certain other 

 respects. Some of the phases have possibly received distinctive names, but our 

 specimens are all of one sex (female) and insufficient for a trustworthy conclusion as 

 to the significance of the vaiiation.

Mimika River and Launch Camp, Setakwa River ; 3 J , 5 S . 



Certain specimens show a transition to L. soror Kr., and may possibly be specitically 

 distinct, but the species of Lomaptera are so variable that the description of isolated 

 forms is only creating obstacles to the necessary revision of the whole group.

A single female of a species closely related to L laticoUis Heller.
