PBOCEEDINGS OF THE NATIONAL MUSEUM. 



a very natural and compact little group with a somewhat disconnected 

 distribution, though it is probable that future explorations may bridge 

 the gaps. One species, H. ceylonensis, is said to occur in Ceylon and 

 Java; another, E. typus, is from Sumatra; a third, H. crepuscularis, 

 occurs in the New Caledonian Islands, and the fourth, the one here 

 described, has thus far only been found in the Hawaiian archipelago.
