ACRIDIIDAE ACRIDIINAE 47 



at a distance from the apex equal to the 

 breadth of the tegmina distinctly narrower 

 than the metazona, the intercalaries and cross- 

 veins of the discoidal area relatively numer- 

 ous, at least in the apical fourth and usually 

 throughout, the venation in general sharp and 

 clearly defined, the area intercalata distinctly 

 defined by the adjustment of the veins at its 

 distal extremity, the humeral vein straight and 

 apically arcuate, nearly always terminating 

 either on the apical margin or but a short dis- 

 tance before it, running for some distance 

 almost exactly parallel to the costal margin or 

 merging insensibly into it ; cerci of male very 

 variable, very rarely styliform, and then the 

 subgenital plate is either exceptionally broad 

 or only moderately narrow, and the apical 

 margin elevated. . . Melanoplus Stal. 

 i*. Head large in proportion to pronotum, 

 nearly half as long again as the long prozona ; 

 pronotum faintly subsellate, feebly flaring in 

 front to receive the head ; tegmina, when fully 

 developed, broad and subequal, hardly tapering 

 in the distal half, at a distance from the apex 

 equal 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 and ill defined, 

 the area intercalata not distinctly marked by 

 the adjustment of the veins at its distal ex- 

 tremity, 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 parallel to that margin 

 nor merging into it ; cerci of male styliform, 

 the subgenital plate very narrow, the margin 

 not apically elevated. Phoetaliotes Scudder.
