As I bave not seen this species, I am unable to decide its true 

 position. Dr. Wallengren compares it to I. marianne ; but I think 

 it possible it may prove to be an Eronia.

Timor {Wallace). 



I have not examined specimens of the above ; but I suppose its 

 position to be next to I. balice. 



The two following species will have to be referred also to this 

 genus, although in many respects they resemble the species of Te- 

 racolus : —

White Nile. Type, B.M. 



The type having lost its abdomen, I have been unable to deter- 

 mine its sex ; I believe it to be a female.
