262 ORTHOPTERA OF NOVA SCOTIA. PIERS. 



identified them as ohscurum, which, as we have said, is now 

 held to be merely a stouter variant of angustum. On speci- 

 mens being finally submitted to Mr. Rehn, the latter positively 

 determined them as A. arenosum angustum, not ornatum. 

 In a letter to me of 7 Nov., 1917, after having once more 

 carefully examined our specimens, he reaffirms this, and 

 says they are perfectly typical when compared with numerous 

 specimens in the Hebard and other collections from the 

 higher regions of North Carolina and northern Georgia, 

 north to Pennsylvania and New Jersey, and that he has 

 also before him material from Massachusetts ard New 

 Hampshire. Knowing the high standing of this gentleman 

 as an authority on North American systematic orthop- 

 terology, and the very extensive collections to which he has 

 access, we accept his decision. Personally I may say that, 

 after comparing specimens with Hancock's original descrip- 

 tion, I consider Mr. Rehn's identification to be correct, 

 our form being merely a more robust variant of angustum, 

 such as Hancock termed injiatum. 



No New England writer, I think, has included A. 

 arenosum angustujn in his published list, Scudder in 1900 

 mentioning only granulatum and ornatum, the short form 

 of the latter being his triangulare. The present finding, 

 therefore, has a bearing on conditions in New England, 

 where angustum has probably been included in ornatum. 

 * There is, of course, no reason why the latter species should 

 not occur here also, and it should be looked for. 



F. Walker in 1871 (Cat. Dem. Salt., v, 813) reported 

 "Tettix ornata Harris" as occurring in Nova Scotia, from 

 a single specimen collected, probabl}^ about 1821, by Lieut. 

 Redman. This specimen is still in the British Museum, 

 and B. M. A. Cummings informs me that it is correctly 

 determined as T. ornatus. Walker's name must refer to a 

 long-pronotumed form, as he also recognized and listed 

 T. triangularis, although not reporting the latter from Nova
