British Guiana, Bartica and Georgetown, from Decem-

(J. 37-41 mm., $ 48-52 mm. Head, palpi, and thorax dark 

 brown ; palpi in (J extremely long, recurved, reaching to extremity

Peru, Chanchamayo, 3500 feet, and Oconoque, 7000 feet, 

 in February ; fourteen specimens. 



Acrolophus rupestris, Wals. 



I have examples of this species from Jamaica with veins 

 2 and 3 of forewings well separated, as well as others with 

 them stalked; and therefore the genus Apodisis, Wals., 

 founded for this species on the latter structure (Biol. Centr. 

 Am. IV, p. 380) also lapses into a synonym, like his eleven 

 others.
