I tak(> pleasure in luimino- this handsome insect in honor of Dr. 

 Marcus Benjamin, the editor of the Proceedings of the United States 

 National Museum. 



SCHISTOCERCA CARINATA Scudder. 



Recently Doctor Kunze submitted to me for identification a pair of 

 this species taken b}" him at Phrenix, Arizona, October 11 and 18. 

 They are now in the National Museum. 



SCHISTOCERCA SHOSHONE Thomas. 



One female, Huachuca Mountains, August '1\)\ altitude, 8,000 feet. 



SCHISTOCERCA VEGA Scudder. 



Three males, Huachuca Mountains, August 22 to 27; six males, four 

 females, Nogales, June 21' to July 11»; four females, Oracle, June It to 

 12; two females, Catalina Mountains, June 6; one female, Patagonia 

 Mountains, May 15. 



While the females of this species seem quite uniform in size the 

 males are quite variable in this respect. The extreme measurements 

 exhibited l)y the males in this series, which perfectly intergrade, are as 

 follows: Pronotum, <> mm. to 8.5 imn.; elytra. 33 nun. to 44 mm.; 

 posterior femora, 16. 5 mm. to 22 nun. 



Aside from the maculate lateral lobes of the prothorax and the 

 more heavily maculate elytra, rHjn is very similar in appearance to 

 *S'. carl IK it a. 



SCHISTOCERCA VENUSTA Scudder. 



One female, Huachuca Mountains, August 15. 



This species is very similar to S. shosJione, and should probably be 

 considered as but a variety of it. The separating character, the 

 median stripe of the pronotum, varies from conspicuous, t3'pical 

 veniista^ to absent, typical -^hoslione. 



CONALCAEA NEOMEXICANA Scudder. 



One male, Huachuca Mountains, August 17. 



The antennje are nearly as long as the posterior femora and are 

 infuscated at the base arid tip, the median portion reddish. The inter- 

 space between the mesosternal lobes is nearly twice as long as broad. 

 The measurements of this specimen are as follows: Antennae, 12 mm.; 

 thorax, 5 mm.; eh'tra, 4 mm.; posterior femora, 13.5 nmi.
