from that species in the short tegmina and the very different pronotum 

 which has the median carina cut a little behind instead of a little in 

 front of the middle, and the lateral lobes not higher than wide and 

 much narrower below than at the lateral carinae. This species also 

 lacks the longitudinal median stripe generally present on the head and 

 pronotum and tegmina of S. hriDincus, and there is scarcely a trace of 

 a median carina on the vertex. 



Described from numerous specimens in the United States National 

 Museum which are labeled Gomphocerns shastanus, Scudd. 



Hab. Salmon City, Idaho. 



XXVI. BRUNNERIA, n. gen. Fig. 26. 



Vertex broad, the distance between the eyes being equal to the width 

 of one of the tegmina at the base, very nearly horizontal, convex, not at 

 all sulcate, with the boundary walls in front straight raised lines which 

 meet in an angle a little greater than 90 degrees (male). The lateral 

 foveolse are deeply impressed, plainly visible from above, rhomboidal, 

 four or more times as long as wide, and with heavy walls which are ap- 

 proximate at the tip of the vertex. The frontal costa viewed from the 

 side is generally arcuate and moderately oblique. It is plain throughout 

 or very slightly hollowed below the ocellus with a single row of distinct 

 punctures on either side. It is rather abruptly acuminate at the apex, 

 suddenly and considerably expanded opposite the antennae, decidedly 

 contracted again at the ocellus, and below rather rapidly expanding. 

 The antennae are slightly depressed, filiform, and considerably longer 

 than the head and pronotum combined. The pronotum has the disk 

 very gently rounded from side to side, a little longer than the top of 

 the head. The anterior margin of the disk is very slightly angulate, 

 the posterior margin is straight or very slightly angulate. The median 

 carina is a moderately heavy raised line, equally distinct throughout, 

 cut once a little behind the middle by the principal sulcus. The lat- 

 eral carinae are slight, moderately sinuate, and cut by the principal 

 sulcus only. The lateral lobes are about as high as long, with the 

 anterior margin nearly perpendicular and the posterior margin consid- 

 erably inclined and the posterior lower angle angulate. The tegmina 

 are abortive and the posterior femora slender. 



This genus is closely related to Stenobothrus, but is distinguishable 

 in having the posterior. margin of the pronotum straight, the lateral 

 lobes not higher than broad, and the elytra abortive.
