probably characterizes the same species, at least so far as we 
know no other species which could answer their description 
occurs.* If this is correct the synonym will stand.

Professor Uhler, in the Standard Natural History (vol. II, 
p. 248) gives the range of the species as from Massachusetts to 
Eio Janeiro in Brazil, thus covering the territory indicated by 
the three descriptions. 
GYPONA GERMAR. 
Although the Gy 2 ^onas have never been recorded as grass- 
feeding species the observations this season show that for one 
of them at least this is an exclusive habit, and for others 
apparently a normal one. 
The species are widely variable in color and size, and the 
genus needs a thorough revision in order to reduce to consistent 
species the long list of so-called species which has arisen from 
the characterization oi these numerous varieties. 
Structurally the species are very constant and present defi- 
nite characters in the shape of the head, the venation and the 
genitalia.

This is the longest and one of the narrowest species in the 
genus, on account of its loog, narrow elytra, much exceeding 
the abdomen. It varies in size from large females eleven or 
twelve mm. long by three mm. wide down to the smallest males 
only seven or eight mm. long by two mm. wide. The vertex is 
two-thirds as long on the middle as the width between the eyes, 
front margin very thin, round ingly produced. Ocelli small, 
slightly behind the middle of the vertex; elytra long and nar- 
rowed to a blunt point behind. The venation is indefinite, con- 
sisting of fine reticulations on the apical half, and sometimes 
including the whole surface except the base of the costa. 
* A series of thirteen specimens of this insect from Cuba, kindly sent by Mr. Robert 
Combs, shows most perfect agreement with Iowa specimens, and no other species of 
the genus is represented in his collecting.
