07-chellmum graciie, n sp. — A slenderer and somewhat smaller insect 

 than either O. vulgare or O. concinnum, from both of which it differs in 

 the form of its pronotum and of the ovipositor. The tubercle of the 

 vertex is short, broad, and has the apex rounded. The tegmina and wings 

 are of moderate length, very delicate in texture, and in the male furnished 

 with an inconspicuous musical apparatus very similar in proportions to that 

 of agile and iongipennis. Legs slender, the posterior femora not quite 

 reaching the tips of the closed tegmina. Terminal segment of the male 

 abdomen quite broad ; the anal cerci stout and acuminate, with the in- 

 ternal tooth minute ; subgenital plate broad and long, reaching beyond 

 the tips of the cerci. The ovipositor unusually long, broad, nearly straight 

 and fine pointed. 



In colour it is pale transparent-green with a broad reddish-brown 

 band upon the head and pronotum, continuous from the tip of the vertex 

 to the posterior transverse indentation of the pronotum, somewhat paler 

 in the middle ; upon the latter, rather broadly bordered by yellowish-
