 as Nysius tnunticuld Dist., none of which it can by any possibility be. 

 It agrees closely with the illustrations of Nysius emenlitun of Distant 

 and is doubtless that species. An adequate diagnosis was not presented 

 by Distant, who mentions none but color and other characters which 

 are common to other forms. I have no doubt but that it will be found 

 the same as some of the species previously described from the West 

 Indian Islands.
