emerge varies with the weather conditions. They may appear 
any time from late in May until late in July. The adults feed on 
the young quince fruits and possibly on the leaves. The eggs 
are laid in “ little pits” made by the female beetles in the fruit. 
The eggs hatch in a few days and the grubs feed in the fleshy 
part of the fruit until full grown when they go into the ground to 
pass the winter. There is but one brood annually. 
Treatment.— As with the plum curculio, jarring is considered 
the most satisfactory method of combating this insect. The trees 
are jarred in the same manner as plum trees for the plum curculio.

be used under the quince trees. As the time when the curculios 
appear varies, probably with the season, no definite time for be- 
ginning the work of jarring can be given. The trees should be 
watched after the last week of May. The presence of the cur- 
culios will be easily ascertained by a few trials at jarring. If they 
are found the jarring should be continued as long as they are 
numerous. 
RASPBERRY DISEASES. 
ANTHRACNOSE. 
(Gloeosportum venetum Speg.) 
Description.— This disease ordinarily makes its first appear- 
ance on the young canes when’‘they are less than a foot high. 
Its presence may be detected by the appearance of small dark or 
purple colored spots, which rapidly increase in size and change 
from the dark color to the brown or dirty white in the center as 
the fungus feeds outward in all directions leaving the dead tissues 
behind. ‘The slightly raised outlines of the spots vary in color 
from dark brown to bright purple. In severe attacks the spots 
are so numerous that they soon coalesce and form continuous 
blotches that may nearly or completely girdle the cane. The 
effect on the cane is practically the same as if so much bark had 
been removed with a knife. While anthracnose is preéminently
