cent paper on the genus (Proc. U. S. Nat. Mus., xxiii, p. 398 399) 

 is quite inexplicable. Stal (Recensio Orthopt., i, pp. 134-135) 

 founded the genus on maritima and ptacida, the latter regarded by 

 McNeill (p. 411) as a synonym of ochraceipennis Blanchard. The 

 reviser of the genus placed these two species in a new subgenus 

 Agonozoa, and uses Trimerotropis s. s. for another subgenus. As is 

 quite apparent Agonozoa is a synonym of restricted Trimerotropis, 

 and a new name is necessary for McNeill's subgenus Trimerotropis. 

 To supply the deficiency I propose Fseadotrimerotropis. 



Circotettix verriiciilatiis (Kirby). 



1837, Locusta verruculata Kirby, Fauna Bor.-Amer., iv, p. 250. 



Two % , one 9 ; Ricketts, Wyoming Co., Pa. ; collected by Stew- 

 ardson Brown, September 1, 1900. Two 9 ; Bellasylva, Wyoming 

 Co., Penna. ; collected by Otto Behr, August, 1900. One 9 ; North 

 Mountain (Ganoga Lake), Sullivan Co., Pa. ; collected by C. W. 

 Johnson. 



The above mentioned specimens, in the collection of the writer, 

 are the first published records of this specimens from Pennsylvania. 

 The southern boundary of the Transition (Alleghanian) fauna 

 probably constitutes the limit of this species.
