60 NEW NORTH AMERICAN ACRIDID.E — BRUNER, 



suer. When the sky is overcast with clouds and during early morning 

 it is very sluggish and can readily be taken. Its presence is easily de- 

 tected by the sharp stridulating sound produced by the males, which 

 closely resembles that produced by some of the Stenobothri and allies. 

 Although of medium size, so closely does its color resemble the plants 

 upon which it lives that it is difficult to find, even though you are aware 

 of its presence upon a particular plant that is quite isolated. 



Pedioscertetes pulchella sp. uov. [PL I, Fig. 10.] 



Olivaceous, variegated with pinkish-yellow streaks and mottlings. 

 The middle two fifths of the wings crossed by a fuliginous baud. Ex- 

 ceedingly hirsute. 



Occiput moderately long, ascending rapidly to the fastigium of the 

 vertex, which is acute ; vertex between the eyes a trifle broader than 

 the shortest diameter of the pyriform eyes, convex; frontal costa very 

 narrow and prominent above the base of the antenna?, where it suddenly 

 diminishes in height, sulcate throughout, the lateral walls gently and 

 evenly diverging, coutiuuous to the clypeus. Antenna? somewhat flat- 

 tened, rather heavy, considerably longer than the head and pronotum 

 combined. Pronotum short, the posterior lobe greatly divergent; an- 

 terior lobes nearly equal, rounded above ; transverse impressed lines 

 rather faint, the posterior one about the middle ; median carina distinct 

 throughout ; lateral carina? present only on posterior lobe as sharp 

 shoulders; anterior margin rounded, ascending upon the occiput; pos- 

 terior margin also rounded, marginate. "Legs slender, somewhat heavi- 

 est in the female ; posterior femora a little surpassing ( S ) or not quite 

 reaching the tip of the abdomen ( 5 ); posterior tibhe as long as the 

 femora, gently bowed downward, the spines minute, slender. Tegmina 

 of moderate width, broadest in middle, the anterior edge somewhat 

 arcuate, posterior edge nearly straight; wings rather narrow, the cross- 

 veins unusually faint and distant. Last ventral segment of male ab- 

 domen acuminate; the preceding segment furnished beneath with a 

 cordate depression, which is margined by sharp carinse that meet and 

 continue as a median ridge to the apex of last segment. Valves of the 

 ovipositor rather large and exserted. 



General color olive green, the male somewhat brightest, streaked and 

 mottled with dull pinkish-yellow. The entire insect covered to a greater 

 or less degree with a whitish powder, which, together with the hair- 

 covered surface, gives it a sort of hoary appearance. The pinkish lines 

 are arranged as follows: On the back of the head, one on each side; 

 another from the lower edge of the eyes obliquely backwards to the 

 back margin of the cheek, where it continues as a border to the lower 

 corners, the carina? of the face, and borders of the clypeus and labium ; 

 on the pronotum as an entire border, on each side of the disk in place 

 of the lateral carinse, and a short backward projection from the middle 

 of front edge of sides to first transverse impressed line; on the teg-
