jointed. Sec. 3, Pemphigini. 
Section 1. 
SCHIZONEURINI. 
i 
This section corresponds with Buckton’s sub-family Schizoneurinm, 
and is distinguished by the following characters: Third discoidal vein 
once forked; antennae six-jointed. In a complete synopsis of all the 
known species it might be useful to divide the section into two sub¬ 
sections based upon the number of branch veins in the hind wings; 
but this is unnecessary here, as I have included all of our species ol 
which I have any knowledge under two genera, each representing one 
of these sub-sections. 
Genus SCIIIZONEURA. 
The characters of this genus are partly given above in describing 
the section. In addition to what is stated there may be added the 
following characteristics: Posterior wings with two branch veins, 
which usually originate close to each other, sometimes in contact. 
The three branch veins of the front wings, and especially the first 
and second, approximate at the base or point of junction with the sub¬ 
costal vein; the third is often obsolete at the base. 1 he antennae are 
short, those of the winged individuals seldom extending beyond the 
end of the thorax; while those of the apterous individuals usually 
reach only to the end of the prothorax; the third joint is longest. 
There are no visible honey-tubes. 1 lie body is usually rather broad, 
elliptical in the winged and broadly ovate in the apterous individuals. 
The colors are usually black, brown or reddish. The beak rather 
long and slender.
