52 NEW NORTH AMERICAN MELANOPLl (oRTHOPTERA) 



111 the present series the width of the eaudal femur is; cf , 4 to 4. 1 ; 9 , 4. 8 

 to 5 mm. The tegmina slightly overlap in the Laredo male, in the others the 

 interval between these organs is .25 to .35 mm. 



Larger series are needed to determine whether the tegminal differences, 

 which appear to aid in separating the races of this sjjccies, are constant in this 

 race and Jiiodistus modestus. 



General color ochraceous-buff (individually tinged with ochraceous-tawny, 

 varying to yellow-ocher), with a conspicuous round spot of ochraceous-buff 

 hit(!rad near base of tegmina. Head marked with blackish as follows: medio- 

 longitudinally on the dorsal surface in a band which is divided by a pale line 

 caudtul, with a postocular streak, flecks on the genae and with a transverse 

 band on each side beneath the antcnnal sockets terminating at the margins 

 of the frontal costa. Pronotum with medio-longitudinal band continued on 

 prozona, there dividing and then converging and forming a very narrow oval, 

 thence quickly becoming obsolete on the metazona; medio-longitudinal carina, 

 sulci and prozonal portion of lateral lobes pictured with blackish, the sutures 

 of the pleura and periphery of the pale spot also blackish. Tegmina with 

 tlie multitude of minute veins ochraceous-tawny, the minute interstices 

 mummy-brown. Abdomen with proximal tergites irregularly suffused with

 genicular lobes which is yellow-ocher; internal face of caudal femora antimcmy 

 yellow, tinged with coral-red ventro-proximad and crossed by the more distal

Like Hhabdok'ttix, this species is thaniiiopliilous and usually 

 found in llioiii bushes, l)ul it is also frefiiunitl}^ encouiitcred in 

 other ve}z;el at ion alTording security. I'lu; c();(n])ai'ative scarcity 

 of the ]>resent I'ace, in the small ])()iiion of the Uni((>d States in 

 wliicji it occui's, causes us to Idiexc thai, in adjaccMil northern

 wider distribution, occuning there much more ubiuidantly.
