oblique and twice waved ; fifth a little longer with its nervule almost 

 straight ; sixth with an acutely oblique long basal nervule which runs 

 back from the base of the preceding; seventh broad, shorter, with 

 its basal nervule directly transverse, but curved backward ; eighth 

 short, broad at base, produced backwards in an acute angle. Ven- 

 ter dark, and with longer pubesence, particularly at the tip. The 

 male has an acute thorn superiorly beneath the apical middle of the 

 superior segment of the anus, and each side of it there is a long slen- 

 der stylet; the inferior segment of the anus is broadly oval, subtrun- 

 cated at tip. 



Length, 26 mm. ; width of pronotum, 12 mm. ; expanse of fore 

 wings, 73 mm. 



One male from the basin of the lower Amazons, perhaps near San- 

 tare m. 



After much hesitation, I characterize this species ; since I can find 

 no description which fits it satisfactorily. Nevertheless, it may yet 

 prove, upon comparison with types, to be one of the species pre- 

 viously described by Mr. Walker.
