298 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxii. 



abdominal segment and infracercal plate of male shaped as shown in 

 iig. 7, the projecting portion of the lattei' scared}' longer than broad 

 and their combined width scarcely as great as that of the former. 

 Ovipositor short, rarely more than two-thirds as long as the posterior 

 femora, about as broad or considerably broader than the fastigium 

 and gently curved upward, the tip armed with a dozen or more sharp 

 elongate teeth on the upper margin and a lesser number below. 



General color, light brownish, with darker mottlings, sometimes 

 uniformly yellowish; lateral lobes of the pronotum usually infuscated, 

 the disk unicolorous or marked with longitudinal dusky stripes; ante- 

 rior and intermediate tibia? and femora usuall}" with one or two more 

 or less conspicuous broad black bands, besides other smaller mottlings; 

 posterior femora longitudinally infuscated on the outer face, some- 

 times with the color bi'oken by three or four light spots; abdomen 

 almost always with a pair of broad dark-colored sul)dorsal stripes ex- 

 tending from the pronotum back across the basal half of tlie al)domen 

 and then deflexing toward the sides, where they meet an indefinite 

 area of infuscation that envelopes the sides of the apical portion of 

 the abdomen. Ovipositor brownish, usuallj^ about the same shade as 

 the ground color of the body.

Type. — In the British musevmi in London. 



Specimens examined. — The National Museum contains three adult 

 males, four females, and several nymphs. These are from Seattle, 

 Washington, Palo Alto, California, and Humboldt and Siskiyou coun- 

 ties, California. Also four females from Wellington, British Colum- 

 bia (To3dore). The Palo Alto specimen, one male, was taken in 

 November; an adult from Seattle was taken in August. The nymphs 

 were taken in March at Seattle and in June in Humboldt county, 

 California. 1 have also specimens taken at Eureka, California, and 

 nymphs taken at Sierra Madre, California, on Ma}' 30, 1906. 



I am indebted to Messrs. Kirby and Waterhouse for notes on and 

 drawings of the type of earhiata. From a rough sketch sent the 

 pronotum is seen to be more bowed out posteriorly than usual, some-

This Pacific coast species is said to extend east to Texas. Scudder 

 mentions a specimen lal)eled as having been taken in Nebraska by 

 Suckley, but he thinks it wrongly labeled, as it is not elsewhere 

 recorded from that region, and Suckley also collected in the North- 

 west. 



Cari iiata is the commonest species of the genus. The Scudder col-
