1918. | BASHAMBAR Das: The Aphididae of Lahore. 235 
Such relations, I have reason to suspect, exist in Lahore also, though the question 
has not been thoroughly investigated yet. 
Very few eggs were observed to be laid on portions of the plant above the soil, as 
is the case with so many other Aphids. 
In June as noted above most of the plants die, but some of them even at this 
time put forth fresh shoots which remain green throughout the rainy season. On such 
twigs early in June some eggs were observed to have hatched into stem-mothers and 
the first generation were yellow; afterwards their progeny acquired the normal 
green. :
