first pair having the carina elevated into a sharp, the sec- 

 ond into a dull, point at the middle ; first two pair of 

 femora mostly wanting spines ; hind femora thick and 

 heavy, turned inward at the base, channelled beneath. 

 Ovipositor generally rather long, nearly straight, but a 

 little concave above, rounded off somewhat abruptly at 

 the extremity to the sharp, upturned point. 



This genus differs from Rhapidophora in the much 

 shorter legs, in the comparative length of the joints of the 

 maxillary palpi, in wanting the terminal spines of the first 

 two pair of femora, and the unusual development of the 

 terminal spines of posterior tibiae, as also those upon the 

 first tarsal joints, in the non-compressed joints of the tarsi, 

 and the shortness of the cerci.
