8. Cerci roughly sock-shaped (Fig. 47). Hind femora 

 robust, not transversely dusky-banded. A large 



robust species with unspotted tegmina bivittatus 



Cerci terminating in a transverse, oval, tumid lobe 

 (Fig. 48a). Hind femora slender, transversely 

 banded. A medium-sized species with the tegmina 

 more or less distinctly spotted punctulatus 



Females* 



1. Tegmina at most but little longer than pronotum 



(Fig. 38) 2 



Tegmina much longer than the pronotum 3 



2. Interspace between mesosternal lobes usually distinctly 



transverse. Mid-carina usually obsolete or faint on 

 prozona. Lateral lobes of pronotum considerably 

 longer than deep the lower half very pale, contrast- 

 ing strongly with the dorsal half. Tegmina shorter 



than pronotum, sub-oval (Fig. 38) mancus 



Interspace quadrate. Median carina of pronotum con- 

 spicuous, equally developed throughout. Lateral 

 lobes about as deep as long, their surface dark brown. 

 Tegmina sub-lanceolate, tapering towards apex, about 

 twice as long as wide (Fig. 38) scudderi 



3. Large, robust; hind femora 16 mm. or over (usually 



18-19). Dorsal area of closed tegmina separated 

 from lateral area by a pale streak which sometimes 



suffuses entire dorsal area bivittatus 



Smaller species ; hind femora not over 14 mm 4 



4. Lower valves of ovipositor about straight, the lateral 



tooth nearly or quite obsolete (Fig. 48b). Interspace 

 between mesosternal lobes transverse. Tegmina 

 dusky-spotted. Hind femora conspicuously banded 



on outside and cherry-red within at base punctulatus 



Lower valves of ovipositor with the apex more or less 

 distinctly decurved and with a distinct lateral tooth 

 midway of the lower outer margin 5 



5. Interspace between mesosternal lobes longitudinal or 



quadrate (Fig. 43). Tegmina usually passing the
