THE CANADIAN ENTOMOLOGIST. 201 



THE XIPHIDIINI OF THE PACIFIC COAST. 



BY A. P. MORSE, WELLESLEY, MASS. 



In the summer of 1897 I devoted several weeks to a rapid 

 Orthopterological reconnaissance of the Pacific Coast, collecting 

 material at various points from Yuma to Victoria, B. C, and the 

 following paper is based upon the specimens secured at that time. At 

 the request of Mr. Scudder, to whose collection and mine the types 

 belong, 1 have studied the material, with the results given below. 



So far as I am aware, no species of this group has hitherto been 

 recorded from west of the Rocky Mountains, although it is exceedingly 

 improbable that specimens are not to be found in entomological collections 

 from that region. In the following paper, four well-defined species are 

 noted, one of them extending entirely across the continent. Two others 

 are of especial interest, from the great variation presented by them accord- 

 ing to locality, and students of the group will do well to collect material 

 in considerable series. 



Orchelimum agile, DeGeer. 



One V , Sisson, Calif., Sept. 3. Identical with New England 

 examples ; taken among the grasses and sedges of a springy meadow. 



Xiphidiian spinosum, sp. nov. 



Fastigium of vertex of moderate width, rather more than one-third of 

 the width between the eyes, the sides divergent when viewed from in front. 

 Pronotum with the hind margin convex, the lateral lobes as deep as long, 

 their posterior margin nearly straight, a distinct sinus at the shoulder. 

 Tegmina narrow at tip, passing the hind femora 1 to 2 mm. and exceeded 

 by the wings by about the same amount. Fore tibiae with 5 or 6 pairs of 

 spines. Hind femora bearing on the under side from 2 to 5 (usually 4) 

 strong black spines, the genicular lobes distinctly bispinose. Subgenital 

 plate of the male truncate, the cerci of moderate length, straight, bearing 

 the usual inwardly-directed tooth at the basal third, the distal two-thirds 

 broad, with subparallel sides, the apex blunt and strongly depressed from 

 above. 



Testaceous, with a dark median band on top of head and pronotum. 

 reaching tip of the fastigium. Antennae rather short, brownish fuscous. 

 Femoral and tibial spines black, or nearly so.
