GLYPHIPTERYGIDAE 
This family is rather scantily represented in the present collection 
which is strange, as a considerable number of species has been described 
already from New Guinea, especially of the genus Imma, and one would 
expect a larger number of new forms. These insects may be more numerous 
along the coast and in low country and many species are of diurnal habits ; 
perhaps these are the reasons that only a moderate number of species 
have been collected by the Expedition which explored more elevated 
regions and collected moths chiefly with lamps.
