During the spring of 1894 the following additional notes were 
made: 
On April 12th large numbers of a ScMzonmTini-Uke louse, 
which resembled the large wingless forms taken the preceding 
fall (Sept. 25) on roots of “Drop Seed” were found in an ant’s 
nest {Lasius latipes?), stored under an old rotten stick. Roots 
of ‘ ‘ Blue Grass ” covered and penetrated this stick. A few were 
apparently attached to the roots. The majority were old fun- 
datrici, apparently full of pseudova. A few specimens of 
larval forms were present. April 18th the same louse, appa- 
rently, was found with the same species of ant on strawberry 
roots. They were also found on roots of Bine Grass, with another 
species of ant {Lasius flavins?). Specimens of each were con- 
fined to root cages, but no winged specimens were obtained. 
April 18th, found eggs of plant lice stored in chambers of the 
nest of Lasius flavins? The color was such that they closely 
resembled the light brown “mite” that is to be found on roots, 
especially around decaying and diseased roots. These were 
taken to the laboratory, where on April 23d they hatched into 
:ScMzoneura-l ike Aphids. 
April 24th, found what is apparently the same larval root 
form of louse, as bred from eggs obtained in ants’ nest, on roots 
of Simrtina cynosuroides Lasius flavins? AJso found a few 
eggs. These differ slightly in color from the larval forms found 
earlier in April on Blue Grass roots and under the decaying 
stick. They are not as light colored, and are more hairy. A 
few days later these larval forms were quite plenty on roots of 
annual Panic Grass, or Setarias. 
May 24, found pupal winged form and fundatrici of what, 
appeared to be the same ScJiizoneura as taken the previous 
spring on roots of Setarias. Winged specimens similar to these 
latter were obtained on roots of Panicum, Mulilenbergia, and on 
(Enotliera biennis in field June 2d, 8th and 26th. 
Apparently none of the Schizoneura corni which were colo- 
nized under netting during the fall of 1893 survived. In fact, 
this species was very hard to find in any locality during the 
spring. A few colonies were located on some low protected 
cornus shrubs. Winged specimens were obtained from these 
colonies as early as May 28. A few winged specimens were 
found as late as June 15. Perennial grass roots were watched 
from the last of May till the middle of July, and the nests of
