Grasshoppers of Kansas.

One male and one female. Sidney, Neb. Bruner collection. 

 This species is unique among the red-legged Trimerotropis for its 

 plain tegmina. 



It seems quite doubtful if this species is distinct from citrina. The 

 tooth on the lateral lobes of the pronotum by which they are separated 

 vary from small, scarcely noticeable projections to quite long points, 

 while the lobes in citrina vary from not a sign of a point to quite a 

 pronounced angle.

Trimerotropis citrina Sc. 

 Bui. U. S. Geol. Sur. Terr., 2, 265; 1876. 



Ash gray, blotched with dark fuscous; foveola? of the head moderately 

 distinct, a slight, lozenge-shaped, flat depression at the tip of the 

 fastigium; antenna? yellowish-brown; obscurely annulated with fuscous. 

 Median carina of the pronotum distinct only on the front lobe, and on its 

 anterior part somewhat elevated, deeply cleft by the transverse sulcations, 

 and sometimes below the general level of the surface at the hindmost 

 sulcation; front lobe corrugate, hind lobe nearly flat, granulose, with a 

 few small, scattered tubercles, the posterior margin recangular. Tegmina 

 and wings extending far beyond the abdomen, the former as in T. 

 vinculata Scudd., but much more uniform, the transverse ashen bands 

 being more infuscated and very rarely so distinct as in that species; 

 wings rather pale lemon yellow at base, pellucid, with black nervules at 

 apex, and near the middle furnished with a broad, blackish, or very dark 

 fuliginous band, shaped as in T. vinculata Scudd., but a little broader; 

 beyond it, half way to the apex of the wing, the space between the 

 anterior two veins is more or less distinctly castaneous. Hind femora as 

 in T. vinculata Scudd., hind tibia? rather pale coral red, becoming very 

 pale at the base, the spines black tipped. 



Length (of average specimens), male 23 mm., female 28.5 mm.; of 

 antenna?, male 12 mm., female 10.5 mm.; of tegmina, male 27.5 mm., 

 female 31.5 mm.; of hind femora, male 12.5 mm., female 15 mm.
