 and body together with all the femora green. The usual 

 reddish-brown stripes on occiput and pronotum narrowly 

 edged with whitish. Tegmina reddish-brown; in the fe- 

 males exceedingly short and pad-like, or well developed and 

 reaching almost to knees; when the former, a little longer 

 than the wings; when the latter, 5 mm. shorter than the

 w^hat less than half the length of the abdomen. There is a 

 reddish-brown band on the dorsal surface of abdomen, 

 darker where it meets the green on sides. Ovipositor pale 

 red, straight, one and a half times the length of the posterior 

 femora. Cerciof male long, the apical half acuminate, curved
