A. rubra, therefore, proves to be a beautiful addendum to the 

 hitherto described species.

A NEW GENUS AND SOME NEW FORMS OF NORTH 



AMERICAN ZYG^NID^. 



By Hy. Edwards. 



Penthetria. Hy. Edw. Nov. gen. 



Similar to the Fabrician genus Procris, but differing in 

 having the antennae slender and non-pectinate in both sexes. 

 The abdomen, too, is without the anal tuft in the female. The 

 genus Procris, as originally indicated by Fabricius, included Ino. 

 Leach and Aglaope. Latr., and it is doubtful if we have any true 

 representatives of either in the United States fauna, the species 

 recognized by Harris under the name of Procris having been, by 

 common consent, placed in Acoloithus and other genera. 



Penthetria Majuscula. Hy. Edw. n. sp. 



$ . Greenish black throughout, with a metallic lustre, want- 

 ing along the costal edge of secondaries. Abdomen with the 

 anal segment golden yellow. 



Exp. wings, 0.90 inch. Georgia. H. K. Morrison. Type. 

 Coll. Hy. Edwards. 



S . Similar to the $ , but a trifle larger and with the anal seg- 

 gent of the abdomen concolorous with the rest of the body. 

 Type. Coll. F. Tepper. 



Penthetria Parvula. Hy. Edw. n. sp. 



Primaries smoky black, with purplish reflections, rather 

 darker about the margins. Secondaries smoky, semi-transparent. 

 Thorax, abdomen, legs, and antennae [concolorous. Under side 

 similar to the upper. 



Exp. wings, 0.60 inch. 



I 6. Indian River, Florida. 



I ? . Georgia. 



Types. Coll. Hy. Edwards. F. Tepper. 



Gnoph/ela vermiculata. G. & R. 



n. var. Continiia. Hy. Ed. 



A form oi G. verjuiadata, probably -common, in which the 

 cuneiform whitish patches of the primaries and the sub-marginal 

 spots are joined together, the whole central portion of the wing 

 being thus sub-diaphanous, exeept a large costal patch behind the 

 cell. In the typical form, a broad band of black crosses the 

 wing, clearly dividing the whitish spaces.
