THE CANADIAN ENTOMOLOGIST 209 



Scudderia furcata ranges as far north as North Bay, Lake Nipissing, 

 where I captured a single specimen in September, 1900. This is probably 

 near its northern limit in this part of the country. 



28. Xiphidion fasciatum, De Geer. 



This widely-distributed insect was found in small numbers at Fort 

 William, Nipigon and in the Temagami District. 



At Nipigon it was the only Orthopterous insect, except Mecostethus 

 lincatus, occurring in the open marsh surrounding the island in the river. 

 Both species were rare, the vegetation being coarse and unsuited to the 

 development of many Orthoptera. At Temagami this species was 

 occasionally met with in long grass growing in sphagnum-bogs. 



29. Idionotus brevipes, Caudell (PL 7, figs. 3, 3a). 



Syn. Platycleis Fletcheri, Caud. 



Four males of this species were taken while stridulating in the open 

 grassy plains east of the river at Fort William. One of these (PI. 7, fig. 

 3a) is macropterous, the others brachypterous. Another macropterous 

 male was seen, but not captured. All were taken in rather long grass. I 

 first determined these specimens as /. brevipes with some doubt, owing to 

 the statement in Caudell's description of this species, that the lateral 

 carina? of the pronotum are well developed and somewhat acute. I sent 

 a specimen to Mr. Caudell, who wrote me that it was the male of his 

 Platycleis Fletcheri, described in his recent Revision of the N. A. 

 Decticinse from a single female. Shortly afterwards, while at Washington, 

 Mr. Caudell kindly showed me the type of P. Fletcheri, and I was satisfied 

 that it belonged to the same species as mine. The close agreement 

 between my specimens and the description of Idionotus brevipes was, 

 however, again brought to my notice while making a further study of the 

 insect, so I sent a specimen to Professor Morse, who kindly compared it 

 with the type of /. brevipes in the Scudder collection and found them 

 identical. The type specimen is somewhat shrunken from immersion in 

 alcohol, and the lateral carinas of the pronotum thus appear sharper than 

 they are in life. 



Although I have no specimens of the type species of this genus, /. 

 Brunneus, Scudd., the descriptions and figures of Scudder and Caudell 

 have led me strongly to the belief that /. brevipes is generically distinct 

 from it, probably constituting a new genus. It does not appear to me to 

 be closely related to Platycleis, as shown by the much larger and more
