This species does not differ in any respect from G. bore- 

 alls, save in the greater size and comparatively greater 

 breadth of the wing-covers, which cover rather more than 

 half the abdomen, and in the much greater length of the 

 wings, which extend considerably beyond the extremity of 

 the abdomen ; there is a very slight ditTerence in some of 

 the prominences of the anterior trochanters ; in coloration 

 and general proportions and absolute size it does not differ 

 from tlie preceding ; it has much the general appearance of 

 G. hexadactyla, Perty, from which it differs in being some- 

 what stouter, in having the teeth of the anterior tarsi long 

 and slender, and in that the ocelli are oval and not subro- 

 tund. Length, 1.33 inches.
