K0.1124. BEVISIOX OF TUE MELAyOPLI—SCUDHEli. 377 



interspace between uiesoaternal lobes umch (male) or a little (female) 

 longer than broad, the metasternal lobes attinj-ent (male) or approxi 

 mate (female); portion of metasternum behind the lobes about twice 

 as broad as long and about half as broad as the greatest brea<lth of 

 the metasternum. Tegmina either abbreviate, broad lanceolate, a<umi- 

 nate, attingent, slightly longer than the i>ronotum, or fully develo)>ed, 

 surpassing the hind femora, rather broad and ecjual, well rounde<l at 

 tip, hardly tapering in the distal half, at a distance from the ai)ex 

 eiiual to the breadth of the tegmina as broad as the metazona, the 

 intercalaries and cross veins of the discoidal area everywhere few, the 

 venation in general loose, irregular, and ill-detine<l, the humeral vein 

 broadly sinuous, terminating on the costal margin at least as far before 

 the apex as the breadth of the tegmina, nowhere running closely par- 

 allel to the costal margin nor gradually merging into it, the area inter- 

 calata not reaching the middle of the tegmina. Hind femoia long and 

 Blender, the genicular lobes pallid with a transverse basal fuscous 

 stripe, the hind tibiae glaucous, sometimes yellowish, with eleveii to 

 thirteen spines in the outer series. Abdomen compressed, medially 

 carinate, apically clavate and recurved in the male, the subgenital 

 plate narrow and long, with lateral margins ampliate at base, the 

 ai»ical margin niesially i)inched but not elevated, the apical face with 

 no subapical tubercle; furcula delicately dev^eloped ; cerci compressed 

 styliform, rather small; ovipositor of female normally exserted. 



This genus is very closely related to Mdanoplus^ from which it is to 

 be distinguished by its large tumid head and subsellate equal prono- 

 tum, as well as bj' its substyliform cerci, though the last characteristic 

 is found in some degree in a couple of species of Melanoplus. The 

 neuration of the tegmina, when the latter are developed, also differs to 

 a certain degree, pointed out in the* descriptions. Bruner' has already 

 expressed the opinion that this tyjie should be geuerically dissociated 

 from other Melanopli. 



A single species is known, found in the western Mississippi basin 

 and bevond its latitudinal limits from Alberta to Mexico.
