hind femora, the body relatively slender. The pro- 

 notum when seen from sides often depressed at 



principal sulcus, with small, uninflated prozona 6 



Interspace between mesosternal lobes sub-quadrate or 

 distinctly transverse (Fig-. 44b). Species with rela- 

 tively stout bodies, swollen prozona, and tegmina not 

 passing hind femora 7 



6. Prosternal spine nearly cylindrical, the tip bluntly 



rounded, often bulbous (Fig-. 41a). Cerci once and a 

 half times or twice as long as wide, sharply pointed, 

 somewhat acuminate, the sides slig^htly concave. Ovi- 

 positor seen from the side with the basal part of the 

 scoop longer, the angle between the scoop and stem 

 more obtuse (Fig. 42b). Hind tibiae red. Hind 

 femora largely or wholly lacking transverse dusky 

 bands except on dorsal part of inner face. Mid- 

 carina of pronotum frequently distinct on prozona 



femur-rubrum 

 Prosternal spine tapering, the tip pointed (Fig. 41b). 

 Cerci shorter, only about one and one-third times as 

 long as wide, rather dull at tip, the sides straight or 

 often convex. Upper valves of ovipositor with scoop 

 shorter, the angle at junction with stem more pro- 

 nounced (Fig. 40b). Hind tibise either glaucous or 

 red. Hind femora usually with conspicuous, dusky, 

 oblique bands. Median carina of pronotum seldom 

 distinct on prozona atlanis 



7. Tegmina about reaching end of hind femora. Inter- 



space but little transverse 8 



Tegmina reaching but one-half to two-thirds the length 

 of the hind femora. Interspace rather strongly trans- 

 verse (Fig. 44b). Very little angulation at junction 

 of scoop and stem of ovipositor ., f asciatus 



8. Scoop of ovipositor very short, deeply concave, with a 



single denticulation or none at base of outer edge; 

 lower valves with the tips correspondingly short and 

 decurved (Fig. 45b). Hind tibiae usually glaucous 

 but often red. Tegmina flecked with dusky and pale 

 spots, hind femora obliquely banded. Lateral carinae 

 of pronotum usually bordered below on the prozona
