The median facial carinae join together near the apex. 

 This should be placed in Ilhumia and not Alolia. This neces- 

 sitates giving a new name to Nesosydne ivailupensis Muir, for 

 which I propose Ilburnia neo wailupensis, new name.

 ()l_vm])iis, Oahu (Timherlake, September 1918). The large,
