368 FAUNA HAWAIIENSIS 



Fam. MALACODERMIDAE. 



The two Insects of this family discovered by Mr Blackburn thirty years ago 

 apparently hold their own at Honolulu, where both have recently been found by 

 Mr Perkins. I suppose both of them to have been introduced, but they have not yet 

 been found elsewhere, and it is within the bounds of possibility that they may have 

 formed part of an old precinctive lowland Fauna now nearly extinct.
