under surface, which become double towards the tip ; the inner 

 valves of the ovipositor have five teeth growing longer and more 

 curved towards the tip, where they are very long and slender. 



Length of body, .8-9 in.; of hind femora, .68 in.; .56 in. ; 

 of ovipositor, .33 in. ; of antennse, about 1 in. 



This species was taken by Mr. Kennicott at Red River, and I 

 obtained it in northern Minnesota, upon the Red River trail, leap- 

 ing about in the grass, at mid-day.

This species varies very much in size and in the proportions of 

 the wing-covers. I obtained it at Red River, and have seen it also 

 from most of the N. England states, where it is somewhat abundant. 



[I enclose the two succeeding species in brackets, because I 

 have very strong doubts whether the specimens obtained by m^ 

 are referable to the species mentioned, and I only place them 

 there now in order to indicate their affinities.

I have this species in large numbers IromNew England ; those 

 obtained at Red River diff"er from these in having a larger body, 

 and a longer ovipositor. 



X. BREVIPENNIS, UOV. Sp. 



This species as found in New England maybe characterized thus: 



Size of X. fasciatiim, with which it agrees in coloration through- 

 out, except that the wings are a little darker, the dorsal band is 

 a little broader and is of a reddish brown throughout, while in 

 X.fasciatum it is green at the base : wings .08 in. shorter than 

 the wing covers, both shorter than the body ; ovipositor nearly 

 equalling the hind femora in length : in these respects it diff"ers 

 very much from X.fasciatum. 



Length of body, .5 in.; of wing covers .33 in.; of hind fe- 

 mora .43 in. ; of ovipositor .4 in. 



The single specimen I have from Red River is smaller than 

 any I have seen elsewhere, has no wings, and the wing covers but 

 .14 in. in length.]
