HoMOPTERA, Boisd. 



The type of this genus is H. putrescens, generally admitted 

 to be identical with H. liinata of Drury, although the description 

 would do equally well for two or three other species. The 

 H. limata of Cramer is a distinct species = H. viridans, Guen. 

 (Cramer's locality alone, apart from differences in the pattern 

 between his figure and Drury's insect, would indicate this). 



Walker's H. edusa is not the well-known variety of H. lunata, 

 figured by Drury, but is = H. adycanthata. 



Homoptera lunata.

The specimen referred by Walker to H. viridans, Guen., is 

 H. lunata. 1 do not understand why Grote has given the variety 

 edusa priority over Drury's earlier name. 



Homoptera minerea.

This is like a smaller form of H. limata ; the costal margin 

 of the primaries is comparatively shorter, but the coloration, 

 pattern, and variation are almost identical. 



Walker's variety sexplagiata was also identified by him as 

 H. minerea and H. obliqua, Guen., though the white patches on 

 the primaries are not mentioned in either of that author's 

 descriptions. 



H. exhausta of Walker (not Guenee) is H. viridans, Guen. 

 The two species are nearly allied ; but, I think, distinct. 



Homoptera viridans.
