width of third segment of maxilla; base of hind tibia without a dorsal 



pale brown area 12. albicaligata (Walsh) 



Temple flat or weakly concave or convex; lower part of occipital carina about 

 1.0 as high as width of third segment of maxilla; base of hind tibia usually 

 with a dorsal pale brown area 13. exulans (Cresson) 



7. Coxae fuscous or blackish, the front and middle coxae often marked with

 usually entirely ferruginous, sometimes more or less fuscous or black in 

 T. semiruhra and T.fuscata 10 



10. Temple at its upper 0.3 fiat, concave, or faintly convex; occipital carina at 



its lower 0.3 very high, as high as the width of third segment of maxillary 

 palpus (these two characters should be used together, with some allowance 



for variability) 11 



Temple at its upper 0.3 weakly to moderately convex; occipital carina at its 

 lower 0.3 usually not so high, usually not as high as the width of third 

 segment of maxillary palpus 13
