MORGAN HEBARD 135 



Chopard's guyanensis is very closely allied, the male hav- 

 ing the facial scutelliim moderately tri-sulcate, both sexes, when 

 compared with infuscata, showing a greater development of 

 the characteristic irregularities of the head, pronotum and ab- 

 domen. The male tegmina are much as in infuscata, but with 

 marginal field broader, as in hogotensis. The striking limb colora- 

 tion, as described by Chopard,'^" is probably the same in all these 

 species; being similar in the males of all before us and showing 

 the identical remarkable coloration in females of infuscata and 

 guyanensis, the only species of which we have material of this 

 sex. 



It would appear very possible that the four known forms of 

 the genus will be found to represent geographic races of a single 

 species.

This species was selected as genotype of Miopteryx by Rehn in 

 1904,^1 and Giglio-Tos' Promiopteryx,^'^ with granadensis selected 

 as genotype, consequently falls under Miopteryx.

This specimen closely resembles a female before us of M. simoni 

 Chopard, from Cariaquito, Venezuela, from which place we also 

 have a male of that species. '^^' These individuals show that 

 females of the present genus lack tegmina and wings; weak convex 

 production of the latero-caudal angles of the mesonotum and 

 metanotum, even less decided than in Fseudomiopteryx, alone 

 being indicated. 



Without males from Cincinnati the determination can not l)e 

 made with certainty, as the female sex has not been described of 

 granadensis or Giglio-Tos' species, simplex (from Venezuela) and 

 fallax (from Bogota, Colombia). The insufficiency of the color
