from the Amazons d)C. 617 



One of the specimens has a mass of eggs adhering to the 

 abdomen. 



I have tliought it necessary to rename this species, which 

 is well described and figured by Pictet ; for Palingenia 

 dorsalis, Burm., is described as having three sette as long as 

 the body, and the head, thorax, back of abdomen, and 

 nervures black. It can hardly be even congeneric with 

 Pictet's insect.

 coniis, Walker, from Georgia, with which it agrees in its
