Grasshoppers of Kansas. 11 



Localities. Finney, Rooks, Sedgwick, Russell, Clark, Lane, Stevens 

 and Douglas counties. 



This species is rather common in the state, and is usually found among 

 the Chenepodiaceae. 



Campylacantha Scudder. 



Body somewhat compressed, rather densely pilose. Head rather 

 prominent, especially in the male, the genae being rather tumid and the 

 summit strongly arched and distinctly elevated above the level of the 

 pronotum, the fastigium descending rapidly, but the face moderately re- 

 treating; interspace between the eyes rather broad (male) or broad 

 (female), the fastigium feebly if at all sulcate, the frontal costa dis- 

 tinctly broadest between the antennae, where it is nearly as wide as 

 (male) or still much narrower (female) than the interspace between the 

 eyes, percurrent, sulcate at least below the ocellus; eyes not very promi- 

 nent nor very large, longer in proportion to breadth in female than in 

 the male, and yet in the female hardly, in the male distinctly, longer than 

 the anterior infraocular portion of the genae; antennae rather coarse, 

 more than half as long as the body of the male, distinctly longer than 

 the head and pronotum together in the female. Pronotum subequal 

 (male) or distinctly and very gradually broadening posteriorly (female) 

 with a rather slight median carina, sometimes interrupted between the 

 sulci, the disk very broadly subtectate, passing by a rounded angle, with- 

 out forming lateral carina, into the vertical (female) lateral lobes, the 

 front margin subtruncate, in no way flaring, the hind margin obtusely 

 angulate, the impunctate or very feebly rugulose prozona nearly or quite 

 half again as long as the punctate or distinctly rugulose metazona, its 

 transverse sulci moderately distinct, that in the middle straight, and fol- 

 lowed a third of the way to the metazona by a similar but arcuate sulcus. 

 Prosternal spine blunt conico-cylindrical, more or less retrorse; inter- 

 space between mesosternal lobes nearly twice as long (male) or half as 

 long again (female) as broad, the inner margins of the lobes nearly 

 straight; metasternal lobes attingent (male) or subattingent (female). 

 Tegmina abbreviated, generally, but not always, a little longer than the 

 pronotum, rounded or subacuminate at tip, their inner margins overlap- 

 ping or separated. Fore and middle femora distinctly gibbous in the 

 male; hind femora variable, as also the coloring of the inferior genicular 

 lobe ; hind tibia with nine to ten, generally nine, spines in the outer series. 

 Abdomen of male very feebly clavate, very feebly upturned, the lateral 

 margins of the subgenital plate not ampliate at the base, the apex bluntly 

 angulate at tip, with a distinct but not very large tubercle, extending 

 beyond the inner side of the apical margin; furcula consisting of a pair 

 of slightly rounded, feebly projecting lobes. 



This genus is closely allied to Hypochlora, but is composed of gen- 

 erally stouter forms, in which the antennae are longer, the pronotum is 

 usually rugulose rather than punctate, and the males of which have more 

 tumid anterior femora, besides the differences pointed out in the table of 

 genera. — 1. c. SCUDDER.
