No material variation in structure or coloration seems to be 

 represented by the above series of paratypic specimens. 



Some species now classed in the genus Bndacusta are very 

 surely wrongly placed. Thus the B. dispar of Redtenbacher 

 from the West Indies, having winged females, probably do not 

 belong here. 



Oecanthus peruvianus Walker.

This specimen probably represents Walker's peruvianus, 

 though the original description furnishes few clews for the cor- 

 rect placing of the species. This female is very slender and 

 the color is greenish, except the tip of the ovipositor, which is 

 black. The wings are caudate, extending about 3 3^ mm. be- 

 yond the tegmina. The antennae are without markings of any 

 kind, the basal segment being concolorous beneath and with- 

 out swellings. The measurements are as follows : 



Length : entire from front of head to end of wings, 18.5 

 mm. ; tegmina, 1 1 mm. ; posterior femora, 8.5 mm. ; ovipositor, 

 5 mm.
