64 CLEAR-WINGED MOTHS. 
found should be pruned below the lowest part of the tunnel. 
The canes that have been cut off should be taken away from 
the garden and burned as soon as dry, or if such pruning is 
done late in the spring the canes should be covered up with 
soil, so as to prevent the moths from leaving. In no case 
should they be left on the ground, because cutting them off 
trom the plant does not kill the borer. The pruning is also 
otherwise of benefit to the currants which are usually per- 
‘mitted to grow too much wood and become too old for the 
benefit of good crops of berries. 
Some varieties of currants and gooseberries are shane 
to be free from borers. If such is the case the writer has not 
seen them. It has also been claimed that black currants are 
not to the taste of such borers, but those under observation 
not only did not escape the ravages of this pest, but were 
even preierred to the red and white currants that grew in 
their immediate vicinity. 
ROOT AND STEM BORER OF BLACKBERRY AND RASPBERR /. 
(Sesia hemizone H. Edw.). 
It is doubtful whether this insect occurs in Minnesota, 
although a broken specimen of it was received from a 
nursery. The larva is a pale worm with darker head and 
legs, and feeds in the roots or base of the canes of the culti- 
vated blackberry and raspberry, invariably killing the canes 
infested, or the entire plant. The worms feed only on the 
pith, and thus cause a wilting of the cane. The canes in- 
fested should be cut out and burned.’ The moth possesses 
golden-brown fore-wings, and as all the borders are wide, 
only a small transparent space is left; the discal mark is 
purple-black, orange behind, with golden reflections; hind- 
wings with golden margins; fringes of both wings golden- 
brown; head black, with a few shining blue scales in front; 
thorax with collar, tegule and base lemon-yellow; abdomen
