Dictyophara belongs in the tribe Dictyopharini of the subfam- 

 ily Dictyopharinse and may be distinguished from the only other 

 two genera, Scolops Schaum. and Phylloscelis Germ, of the same 

 tribe which occur north of Mexico, by its triangularly produced 

 vertex. 



This paper is based upon a large series of specimens in the col- 

 lection of the U. S. National Aluseum.

Dictyophara may be characterized as follows : Vertex pro- 

 duced triangularly with three carinje, the median one in certain 

 species ending before the middle; three frontal carinse more or 

 less parallel : pronotum short and emarginate on posterior border : 

 forewings long, greatly exceeding the abdomen and more or less 

 reticulate. Species usually bright green with but slight color 

 markings or variations. The logotype of the genus is europcea 



Linn. 



Key to the Species. 



1. Transverse veinlets of the forewings forming three nearly regular 



bands dioxys Walk. 



Transverse veinlets of the forewings in no regular pattern 2. 



2. Length of vertex twice or more its basal width microrhina Walk. 



Length of vertex slightly longer than its basal width 3. 



3. Frontal carinse meeting in an obtuse angle and tinged with black. Fe- 



male plates short, extremely broad and rounding florens Stal. 



Frontal carina meeting in an acute angle and not tinged with black. 

 Female plates long and narrow lingula VanD.

 , of Hom., Suppl., p. 61, 1858; Nersia ciirviceps Stal, Bidr. Rio 

 Jan. Hem., p. 64, 1861. 



This species may easily be separated from the other three 

 species by the cross veinlets of the forewings forming three more 

 or less regular bands. The vertex is hardly twice as long as wide 

 and in this respect would come between microrhina and lingula. 

 It is known to occur from New Jersey south and west through 

 Texas.
