 Indigens Series. 



I am inclined to place here an interesting species'i^ sent to me by 

 Dr. Hancock from the mountains of Arizona, although it differs con- 

 siderably from the single species formerly placed here and will require 

 some modification of the characters given to the series in my former 

 table (Revision, p. 125), and in the text (p. 210), in that the anal 

 cerci, though broad and long and subequal, do narrow considerably in 

 the basal half, and in the middle are distinctly narrower than the 

 frontal costa, and are incurved and apically angulate, while the apical 

 margin of the subgenital plate is not elevated to a blunt tubercle; 

 furthermore its abdomen is distinctly clavate at tip and the supraanal 

 plate does not have the lateral margins mesially notched. The points 

 of distinction between the two species may be tabulated thus:

(7i. Tegmina slightly distant ((j^); abdomen of male hardlv clavate at apex; 

 supraanal plate with lateral margins mesially notched; cerci straight, 

 scarce'y tapering in basal half, broader than the frontal costa, apically 

 rpunded or subangulate ; subgenital plate considerably elevated apically 



into a slight rounded tubercle indigens Scudd . 



d^. Tegmina attingent ((^) or subattingent (9); abdomen of male dis- 

 tinctly clavate ; lateral margins of supraanal plate entire ; cerci incurved, 

 tapering distinctly in basal half, narrower than the frontal costa, apically 

 produced and angulate ; subgenital plate with the apical and lateral mar- 

 gins in the same plane, without tubercle femiir-mgrwn sp. nov. 



Melanoplus femur-nigrum sp. nov. 



Plate Vlf., Figure 4. 



About or rather below the medium size, dark fuscous above, pale 

 flavous beneath and with pale flavous markings, conspicuous in a stripe 

 following the lower margin of the outer face of the hind femora, and 

 an oblique metapleural stripe. Head not ])runiinent, plumbco-testaceous 

 infuscated above, the vertex gently convex, slightly elevated above 

 the pronotum, the interspace between the e)'^es fully as wide as (d^) or 

 considerably wider than (9) the first antennal joint; fastigium steeply 

 declivent, distinctly sulcate, at least in the male; frontal costa sub- 



* I am not able at the moment to compare this directly with the species on which the 

 series was founded.
