NEMOBIUS, Serv. 

 Nemobius, Serville, Hist. Nat. des Ins. Orthopteres, p. 345 (1839), et auctores. 



A genus including small species of brown or brownish-testaceous colour, with 

 variable markings. Some species have long, caudate wings ; others do not possess 

 hind wings, and have abbreviated elytra. The principal specific characters of the 

 species, apart from this, are to be found in the form of the ovipositor — straight or 

 somewhat curved, — and in the denticulation of the end of its superior margin.
