This species is readily distinguished from all other N. 

 England species, by the great length of the wings, which, 

 surpassing in length the wing-covers, hang over the ex- 

 tremity of the abdomen ; contrary to the supposition of 

 Serville, this is true of the male as well as of the female. 



Length of ovipositor in seven individuals, .29-.39 in., 

 average .35 in., length of hind femora, .20-.245 in., 

 average, .225 in.

This and G. luctuosus, Serv. are our largest species ; it is 

 remarkable for the great length of the ovipositor of the 

 female ; the wing-covers are generally dark, bordered with 

 light brown, though sometimes they are quite pale through- 

 out ; they generally quite cover the abdomen. I have never 

 seen this species north of Cape Cod, and am inclined to 

 think it a more southern form, the insect fauna of Cape 

 Cod being closely allied in character to that of Pennsyl- 

 vania. 



Length of ovipositor in seventeen individuals, .34-.42 

 in., average, .37 in.; length of hind femora, .21-.23 in., 

 average .22 in.
