OBSERVATIONS. 



This species frequently occurs in various 

 parts of the United States, in fungi. It is very 

 distinct from any other know^n insect of the 

 genus. The thoracic processes, as well as that 

 of the head, afford very good and striking cha- 

 racters. We have never heen so successful as 

 to ohtain the ahove quoted work of Panzer, 

 and we therefore refer to it through other 

 authors. 



The two upper figures of the plate represent 

 the male in different positions. 



The lower right figures exhibit the female. 

 The lines show the natural length.
