colourod sj)ot tmvanls the iiuuT inar^'iii opposite the trianguiur 

 spot on the custa. \Viii<2;s smoky hyaline, with nifo-testa- 

 ceous ncrvuiea tuwaida the costa and brown ones elsewhere ; 

 the transverse nervures are whitish : or the wings are 

 frequently pale subhyaline, with l)rown borders. Logs 

 black, with black or red spines ; coxaj often bordered by a 

 pale line. In some varieties the legs are red, or the whole 

 under surface of the body is black, or the under surface of 

 the abdomen is transversely banded with black, or the red 

 markings of the tegmina are reduced to a streak at the base 

 of the costa, a streak or spot below the subcostal area oppo- 

 site the end of the basal area, and a spot on the lower part of 

 the costal area at threo-tit'ths of its length. Nothing seems 

 constant but the colour of the antennaj and pronotum, and 

 even the reddish hind border of the pronotum is interrupted 

 behind in some specimens. But all these variations grade 

 into each other too much to allow of their being regarded as 

 distinct species.
