82 JURINIA XITIDA. 



gentine republic , sent to me by Prof. Weyenbergh in 

 Cordova. 



The species is closely allied to J. hicolor Wied. (Auss. 

 Zweifl. 11. 282. 3) , and I would have identified it with 

 this , had not Wiedemann mentioned a pattern on the tho- 

 rax , of which hardly anything is visible in my specimens, 

 though they are in general well preserved. He moreover 

 describes the anus as being a little transparent and reddish.
