example, which is represented exactly by one of our Mexican

 Primaries angulated at extremity of third median branch ; 

 discocellulars angulated ; the lower radial emitted from the 

 centre of the discocellulars ; second and third median branches 

 separated at their origins : secondaries with an acute angle at 

 extremity of third median branch ; first subcostal branch emitted 

 before tbe end of the cell ; discocellular veinlet concave ; second 

 and third median branch.es emitted sej)arately as in the primaries :

Nepheloleuca, gen. nov. (Plate IX. figs. 11, 12.) 

 Form of Gonorthus, and with very similar neuration, excepting 

 that the subcostal branches of the secondaries are not emitted 

 quite at the same point, that the second and third median 

 branches are also separated by a short space at their origins, and 

 that the radial is very oblique and subangulated towards the 

 anterior angle of the cell : antennae very different, not pectinated 

 in the male, but with fine short cilia along the anterior margin. 

 Type N. politia.
