on dorsal and lateral surfaces, grayish-yellow beneath ; in $ with the 

 dorsal surfaces of the first three segments shining black, elsewhere yellow- 

 ish-gray, with a row of dark spots along the dorsum. Hind femora dark 

 sooty brown above, with a i&w small light spots along dorsal surface, the 

 dark colour extending down irregularly over about half or more of the 

 inner and outer surfaces, where it is more or less broken into blotches ; 

 elsewhere pale testaceous, lighter internally. Legs dark sooty brown, 

 variegated with pale testaceous. Ovipositor about as long as the body, 

 and about one-fourth longer than the hind femora, nearly straight, stout, 

 the apical blades tapering evenly to a fine point, the teeth sharp, promi- 

 nent, and nearly equidistant.

12 ^ c?, 13 ? ?. Toronto, Au^. 16, Sept. 8, 1902 ; Sarnia, Aug. 

 16, 1901 ; De Grassi Pt, , Lake Simcoe, Aug. 3, 1903; Sept. 15, 190 1. I 

 have a single long-winged female, taken at High Park, Toronto, Aug. 

 16, 1902. 



This is a well-marked species, easily distinguished from IV. fasciatus 

 by its much smaller size, grayish coloration, more distinct dark mark- 

 ings and longer ovipositor. It has the longest ovipositor of any of our 

 species. 



It occurs only on sandy soil, where the vegetation is somewhat scanty. 

 I have never taken it in large numbers, but in High Park, where all my 

 Toronto specimens were taken, it is by no means scarce when looked for 

 in the proper kind of locality. Its pale colours renders it very inconspicu- 

 ous against the sand. 



The chirp of the male is a feeble, continuous trill, more high-pitched 

 than that c>i fasciatus or angusticol/is', and much shorter than either.
