[Read 6th May, 1886.] 



Many of the insects characterized in the following paper were 

 collected in the Eastern Archipelago by Mr. A. R. Wallace. 

 Types of all the species mentioned are contained in my col- 

 lection. 



Genus Aulacophoea. 



Many of the species of this genus, more especially those 

 described by the older authors, are in a state of great confusion, 

 arising to some extent from the great similarity in general 

 appearance and coloration of many of them ; but principally 

 from the brief descriptions given by the various authors and from 

 the total absence of any reference to structural characters. 



In the present paper I have attempted to work out some of 

 these species, pointing out the structural characters by which 

 they may be separated. I have retained, in most cases, the old 

 names, although I cannot be sure in every instance that the 

 species to which they are assigned were those from which the 

 descriptions were originally drawn. 



I have not attempted to work out the whole genus, many 

 species sufficiently characterized by their respective describers, as
