Ranr^e Admiralty Islands and Ruk Island, southern 

 Bismarck Archipelago. This would seem to involve occur- 

 rence in the other islands of the Bismarck Archipelao-o • but 

 as these are occupied by D. pradatrix, a species of about the 

 same size but of quite another group, it is possible that the 

 range ot Z>. a«o?«r5^ni- is really interrupted, and onlv covers 

 the two islands first mentioned.

This species is in size intermediate between D. exoleta SimX 

 moluccensis, and Hlls up the gap between " a. Much smaller " 

 and "/..Much larger" in Dr. Andersen's synopsis of the 

 species (Cat. p. 459). It is also readily distinguishable from 

 any of the other species of the section by its very much 

 darker colour. 



I have named the species in honour of Dr. K. Andersen in 

 recogniLion of tlie striking monograph of Doksonia contained
