LITHOCOLLETIDAE 
One single species of this large family of leaf miners has been described 
from New Guinea before. The discovery of several hundreds more can be 
expected in future. Hr. L. J. Toxopeus told the author that he observed 
very numerous leaf mines of different lands during the Expedition, but 
had no opportunity for breeding them.
