a been tunable to find any record of the insect having 
tn taken in Pennsylvania before, although Dr. Smith records 
ron several neighboring states and says “It is quite prob- 
that the species will be found throughout the United States 
rever the food plant (Typha) occurs.” 
¢ situation in which the larvae were found consists of a 
RSG cenad by the seroovel of clay foc ie 
of a brickyard in operation nearby. These pools are bor-

Bon healthy pupae were found in one stem. The plants in

75 per cent. of the plants in the marsh seemed to be 
infested, but some animal seems to have a special fondness for 
othe fat pupa, as more often than otherwise it had been extracted 
thr a hole broken in the side of the stem. In some cases 
this seemed to be the work of a rodent, judging from the drop- 
F that were found about such places. Observations lead me 
to believe that this species does not feed below the water line 
in its burrows. In cases where the water had receded from the 
[ - base of the plant, the larva invariably descended to the very 
_ crown. But I was unable to discover a single case in which
