Two species previousl}' known only from localities south of the 

 United States are here recorded from north of the boundary line, while 

 two are described as new. 



MANTID^. 

 Stagmomantis graoilipes n. sp. 



Type: o^ ; Baboquivari Mountains, Pima County, Arizona, I'DOe 

 (F. H. Snow). [Coll. University of Kansas.] 



Allied to *S. venusta, heterogcwna, montana and androgyna Saussure 

 and Zehntner and limhata Hahn. From venusta, limhata and andro- 

 gyna it can be immediately separated by the slenderer pronotum and 

 limbs, particularly the cephalic femora; from heterogamia it can be 

 separated by the much greater size, narrower supra-coxal expansion 

 of the pronotum and the comparatively longer limbs ; from montana it 

 differs in the smaller size, except the length of the cephalic femora 

 which is about the same in both forms, in the nar- 

 rower costal margin of the tegmina and in the wings 

 being strongly marked and not vitreous. 



Size medium; form slender. Head broad, the 

 depth but little more than half the width. Prono- 

 tum slender, the greatest wudth contained nearly 

 six times in the length; cephalic margin rounded, 

 the collar with parallel sides, the expansion slight, 

 shaft compressed but slightly expanding caudad, 

 margins of the collar slightly crenulate, shaft dis- 

 tinctly carinate. Tegmina slightly more than twice 

 the length of the pronotum; costal field moderately 

 expanded proximad, not appreciable in the distal 

 third, coriaceous; stigma linear, longitudinal, not 

 sharply marked. Wings not exceeding the tips of 

 the tegmina when in repose. Cephalic limbs quite 

 slender, coxae slightly less than two-thirds the 

 length of the pronotum, distinctly but not strongly 

 spincd on the cephalic margin with two grades of 

 spines, caudal face with the surface rugose owing 

 to the presence of short spiniform tubercles, between which the 

 surface is uneven; cephalic femora very slightly shorter than 

 the pronotal shaft, the principal discoidal spine being situated very 

 near the middle, lateral margins armed with five spines, one of which is 

 small and genicular in position, internal margins armed with fourteen 

 to fifteen spines, one small and genicular and the remainder divided
