The abundance of the common corn plant-louse m all the fields 
of sorahum and broom-corn visited has already been noticed. This 
vevv common and widely distributed species has received from ento- 
Xl far less attention than its importance would warrant 
having in fact been studied only bv Fitch, Walsh and Thomas ’ as 
for ns 8 the nublished literature of the species indicates It seems 
lw common consent to have been left in the genus Aphis, to which 
•it was assigned by Fitch, but the form of the lioney-tubes assimi¬ 
lates it to the genus Ehopalosiplium of Koch, and ^ stinet ^ se P n

liardly be considered’real, however; and nothing is to be gained by 
disturbing the nomenclature of the corn plant-louse, especia y as 
1 as the leneral aspect of a true Aphis. The honey-tubes, swollen 
in the middle and* dilated at the tip, will serve to distinguish the 
species from any other of our Aphides. 
DESCRIPTION. 
The following description of this species given merely to render 
rA hie its distinction from the other plant-lice infesting these 
kops is quoted fn part from the Eighth Report of the State Ento- 
“Mr. Walsh describes those he found infesting the roots [see 
Plntp TV FiV 8 1 as having the general color, both of the pupa ana 
ner ect insect pale green the female pupa usually has three short, 
transverse^ dark lines on the thorax, and three similar ones on he 
abdomen. ’ The antennse are unusually short, scarcely reaching the 
tip of the thorax; the honey-tubes are also rather short; the fi^ 
discoidal vein is farther from the second than the second is from 
the third, and the stigma is prominent and pointed at eac en 
He states that the pupa is dusted oyer with a whitish bloom 1 
that of a plum, and with dusky markings.
