DERiEOCORIDiE. 331 



We have only seen 2 examples of this insect, both of which are 

 very imperfect, and the description is, therefore, necessarily impaired. 

 Dr. Fieber, from whom we borrow the following part of the diagnosis, 

 has seen and determined one of the specimens. Of the (^ he says 

 that there is a " longish black streak in the hinder angle of the 

 corium, and another at the apex of the anterior margin. Sternum 

 ferruginous yellow, its sides and the middle of the Mesosfernum 

 blackish. Abdomen black underneath, base and sides red ; the anus 

 with 2 large red spots." 



One specimen in the collection of Mr. Dale, the other taken by 

 Mr. Reed in Leigh "Wood, Bristol. In neither case can we give the 

 date.
