I (^ > 3 ?• — California; San Francisco, CaL, Edwards. 

 This species differs from the Mexican ,5*. vicinus, to which it appears 

 to be most nearly allied, in its dorsal colouring, smooth gense, stout and 

 non-sulcate hind femora, the fewer spines on the outer carina of the hind 

 tibiae, and its longer, inequal calcaria. 



Ajiostostomata. 



To this group the United States can furnish but a single genus. 



Cyphoderris Uhl. 



As stated above, this genus was accidentally omitted from my Guide 

 to the . . . N. A. Orthoptera, but its position therein is here indi- 

 cated.* It falls in the vicinity of Pherterus Brunn., found in the Antilles 

 and Brazil. It is the only one of our Stenopelmatinse which is not 

 apterous. 



7. Cyphoderris monstrosa Uhl. — Oregon. I have seen only Uhler's 

 types. Thomas records it from Wind River, Wyoming. 



Rhaphidophorini. 



Represented in the United States and on the Pacific Coast by two 

 groups, Tropidischiae and Ceuthophili. 



Tropidischice. 

 The sole representative of this group occurs only on the Pacific 



Coast. 



Tropidischia Scudd. 



A remarkable long-legged form, the hind tibiae quadrangulatc, with 

 spines on each margin, and represented by a single species. 



8. Tropidischia xafithostOJtia'Sicudd. — Crescent City, Del Norte Co., 



Cal., Agassiz ; Mendocino, CaL, Behrens ; Philomath, Benton Co., Oregon, 



Sept. 15, A. P. Morse. 



Ceuthophili. 



This group contains the bulk of the Pacific Coast, and indeed of 

 North American, Stenopelmatiuce ; most of them will be found in my 

 paper on the North American Ceuthophili (Proc. Amer. Acad. Arts Sc, 



*It is well to state here that I also' overlooked Uhler's genus Camptonotus, 

 described in the same paper with Cyphoderris. It is identical with Brunner's genus 

 Neortus, and has priority.
