A male and a female from the Fiji Islands. 



The nearest ally o{ this rsn-e sipecies is Actaeodes Richtersii 

 de Man, from Tahiti. As regards the general form and 

 structure of the cephalothorax , these two species closely 

 resemble one another. The regions of the upper surface , 

 which is somewhat convex in the anteroposterior direction 

 and slightly also transversely , are as little defined as those 

 of Act. Richtersii, at least in these two specimens, one 

 of which has been kindly determined for me by Milne 

 Edwards. The sutures defining the gastric region are absent, 

 so that the quoted figure in the »Nouvelles Archives", in 

 which they have been figured, is perhaps not exact. I observe 

 only the median frontal furrow, which is divided itself as usual 

 in two furrows, but these two furrows are short and do 

 not reach to the lateral borders of the gastric region. The 

 grooves defining the gastric and cardiac regions are indeed 

 quite absent in these specimens , and only two small im- 

 pressed points , placed in a transverse line near one another ,
