The specimen figured contained twenty -four embryos 
in various stages of development. 
This species feeds on many plants, particularly 
Lactuca oleracea, Lactuca scariola (garden lettuce), 
Sonchus, Crejpis^ and other plants. It also may be found 
on the leaves of both Bihes grossularia and Bihes nigrum. 
The branching of the wing-veins is somewhat variable, 
and the length of the antennse also differs in some 
individuals. 
The insect is commonly met with throughout the 
whole summer. It does not answer to the description 
given by Koch of his S, lactucce, which certainly must 
be a different species.
