 In a forthcoming paper we intend to make some detailed 

 comments on this species, its relationship and distribution.

 Independencia, Parahyba. (Mann and Heath.) Two fe- 

 males. 

 Aside from the Peixe Boi representation, all of these specimens 

 have been immersed in alcohol and in consequence have lost much 

 of their original color tones. The disk of the wing is either dis- 

 tinctly, or shows traces of being washed with yellowish in the 

 specimens which have been in liquid preservative, while the Peixe 

 Boi male has a pale bluish and the female a glaucous tint to the 

 same area. One of the Para females has a yellowish wing colora- 

 ation, which apparently has had a minimum of alteration, and it 

 is very similar in this respect to British Guianan material. 



There has been so much confusion regarding the relationship 

 of the very closely allied forms of this genus, that a good portion 

 of the distributional data published in the past has little value 

 on account of the strong [)rol)ability of erroneous determinations. 

 We feel that this genus is very closely related to Abracris, and 

 should not be placed in the isolated position generally assigned to it. 

 The present species appears to range from Golonibia to eastern 

 Brazil, to the upper Amazonian region.
