Measurements: Male — Length of body, 19 mm.; of tegmina, 32 

 ram.; of hind femora, 21 mm.; of pronotum, 5.5 mm.; width of 

 tegmina, 10 mm. Female — Length of body, 19 mm.; of tegmina, 

 27 mm.; of hind femora, 20 mm.; of pronotum, 5.5 mm.; of ovipositor, 

 6.5 mm.; width of tegmina, 9 mm. 



Pistillata is a species of northern range, its general distribution 

 being "Northern United States and Canada east of the Great Plains." 

 It is a scarce insect in Indiana, having, up to the present, been taken 

 in small numbers only about the peat bogs and borders of lakes in 

 I'ulton and Kosc-iusko counties. Mr. Scudder, in his revision of the 

 group, was mistaken in referring the species described in my former 

 paper under the name of furculaia to pistillata; as the measurements 

 in my paper will prove. They belonged to curvicauda as at present 

 limited, and are so placed in this paper.

This is the smallest, and at the same time, our most common 

 species of the genus. The general color is a dark leaf green, the 

 head and pronotum paler; the latter without trace of yellow on its 

 carinse. The anterior margin of the pronotum is but slightly nar- 

 rower than the posterior, whereas in the three preceding species the 

 difference in width is plainly perceptible. The notch of the supra- 

 anal spine of the male is deep and rounded, forming a curious fork- 

 like appendage, the lateral processes of which are much swollen.
