the itiuer carina with similar but uniform spinulation, none so large 

 as on the outer carina (J') or with a few minute spiuules on the 

 apical half (9 ), the intervening sulcus not very broad. Hind tibiae 

 feebly undulate in the basal half in the male, slender in both sexes, dis- 

 tinctly but not greatly longer than the femora, armed beneath with a 

 single preapical spine or occasionally with two minute unaligned 

 spines besides the apical pair ; spurs rudely opposite, the basal at the 

 end of the proximal third of the tibia, more than half as long again as 

 the tibial depth, set at an angle of about 40° with the tibia and divari- 

 cating 90-100°, their tips incurved; inner and outer middle calcaria 

 sube(|ual, more than twice as long as the others or as the spurs, and as 

 long as the first tarsal joint. Hind tarsi about two fifths as long as 

 the tibiae, the first joint shorter than the rest together, the second twice 

 as long as the third and with it longer than the fourth. Cerci stout 

 in the proximal half, tapering beyond, about two thirds as long as the 

 femoral breadth. Ovipositor nearly two thirds as long as the hind 

 femora, shaped and armed as in G. terrestris.
