G. macrurus and G. guttatus, like il, have long bind tibia?, but in these 

 two species the spines are much siouier. G. macrurus agrees with it also 

 in the prothorax, which is sliuhtly narrower in front, and in the head, which 

 is rather smaller than that of the more typical species.

Male. Black, shining. Fore part of the head and sockets of the 

 antennae tawny. Eyes, palpi and antennae piceons. Abdomen beneath 

 towards the base and pecius tawny. Cerci much shorter than the abdomen. 

 Legs blackish ; femora partly tawny beneath ; hind femora with oblique 

 tawny streaks; bind tibiae with five tawny spines on each side. Fore wings 

 piceous, extending very little beyond the abdomen ; apical part thickly 

 reticulated. Hind wings not developed. Length of the body 7\ lines. 



The smaller spines on the hind libias of this species and their reddish 

 colour distinguish it from G. alratus.

Mas. Testat'eus, nitens ; caput nigro fascia turn ; palpi picei ; prothorax 

 transverse impressus ; femora postica substrigata ; alee anticcecinerece, 

 abdomen paullo superantes, villa testacea, spatio subcostali diaphano ;

Male. Testaceous, shining. Head with a black band between the 

 eyes, which are lurid. Palpi piceous. Prothorax with a transverse 

 impression at a little behind the middle. Hind femora with slightly indi- 

 cated darker streaks. Fore wings cinereous, extending a little beyond the 

 tip of the abdomen; a testaceous stripe along the mediastinal vein: 

 anterior space pellucid. Hind wings not apparent. Length of the body 

 Q lines. 



The specimen described is injured, and the number of the spines of the 

 hind tibiae cannot be ascertained. The hind tibiae are much shorter than 

 those of G. guttatus and of G. posticus.
