464 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxviii. 



Bureallx^ represented by two females from Colorado, is scarcely dis- 

 tinguishable from minoi\ the pronotum of the female being somewhat 

 less tuberculous than in typical inlnor. The female elytra also seem 

 slightly more elongate in the specimens before me. 



The length of the elytra of these insects varies considerably in the 

 males, the maximum being 22 mm. and the minimum 16 mm. The few 

 specimens ])efore me, however, exhibit a complete gradation from the 

 greatest to the smallest measurement. The females have the wings 

 inf uscated mesially for nearh" their entire width. As a rule the females, 

 being inseparable, must V)e placed according to their locality unless 

 associated with the males. A sufficient amount of fresh material would 

 very probably justify the reduction of one or more of these species to 

 the rank of variety. 



STAGMOMANTIS LIMBATA Hahn. 



Nine males, Nogales, June 15, August 3; one male, one female, 

 Huachuca Mountains, June 29, August 13. Two immature females, 

 Catalina Mountains, June 6. 



This species is readily distinguished from Carolina by the female 

 having the costal area of the elytra much broader and by that of the 

 male being opaque instead of transparent or translucent, as in carol ma. 



BACTROMANTIS VIRGA Scudder. 



Four males, Huachuca Mountains, August 15. Four males, Nogales, 

 June 15, July 19. 



These specimens are larger than a single male specimen in the U. S. 

 National Museum from Phoenix, Arizona. The elytra of this latter 

 measures but 21 mm. and the pronotum 9 mm., while the elytra of 

 the former measure 24 to 26 mm. and the pronotum 11 mm., except 

 one of the specimens from Huachuca Mountains, which is scarcely 

 laro;er than the one from Phoenix.
