the middle of face below the center of eyes ; vertex narrow, trans- 

 verse, a little elevated above the eyes. Pronotum very long, in our 

 species forming two-fifths the whole body, its apical third wider, 

 with edges carinate and, in female, armed with minute distant 

 teeth. Tegmina of female broad, opaque and bearing a spot or 

 stigma of different texture near the center; teguiina of male nar- 

 row, longer than abdomen, with stigma often indistinct or want- 

 ing; wings of female, when expanded, of the form of a quarter 

 circle, those of male longer and narrower. Abdomen of female 

 large, more or less dilated; that of male narrow, the supra-anal 

 plate small, its apex rounded; subgenital plate very large, its 

 apical third much narrowed, styles very short. 



Stagmomantis is an exclusivery American genus, 20 species, 

 mostly from Central and South America, having been recognized 

 by Kirby (1904, 252). A number of these are now known to be 

 synonyms but several have since been described. Only five are 

 known from the United States, and of these but two occur east of 

 the Mississippi, the other three ranging from Texas to California.
