Three £,2 $, 1 immature $, Coronado, Calif., July 24, on salt- 

 marsh; collected by A. P. Morse. 



Xiphidium occidentale, sp. nov. 



Fastigium of vertex very broad, at least one-half as wide as the 

 distance between the eyes, blunt, convexly rounded in front ; viewed from 

 before, as wide as deep, the sides very strongly divergent. Lateral lobes 

 of the pronotum usually longer than deep, the hind margin straight or 

 nearly so, passing into the hind margin of the posterior process with but a 

 slight sinuosity. Dorsum of the pronotum with the front and hind margins 

 truncate or slightly convex, the front margin sometimes slightly excavate. 

 Tegmina of the male covering two-thirds or three-fourths of the abdomen, 

 rarely all but the cerci, of moderate width, rounded at the apex ; those of 

 the female covering about one-half of the abdomen, in var. camurum 

 reaching apex of the hind femora, the distal portion wide, with well- 

 rounded apex. Wings equalling tegmina except in camurum, in which 

 they exceed them about 2 mm. Spines of the fore tibiae 5 or 6 pairs. 

 The hind femora unspined, the genicular lobes pointed, scarcely spinose. 



Cerci of the male long, stout, the apex regularly tapering, acuminate 

 and very slightly depressed at tip, the lateral outlines slightly sinuous, 

 the usual stout, inwardly-directed tooth present near the base. Ovipositor 

 of the female two-thirds to seven-eighths as long as the hind femora, 

 slightly curved upward in both margins, tapering very gradually to the 

 slender tip. 



Brown above, with brown or green sides, and usually with a broad 

 dark-brown median band on head and pronotum (often also on exposed 

 portion of abdomen of female), bordered on each side by a pale yellowish 

 stripe; the dorsum of abdomen of young with a broad fuscous band.
