OF 
Oo 
so to speak, to extreme southern Ohio, by the severe winter 
of two years ago. Last year it was not reported as present 
at all, but we found a few of them breeding in Clermont 
county. This year it is coming to the front again in the 
extreme south, attacking cabbage in Clermont county and 
rape in Gallia county. 
For eight years I have been searching about Wooster 
for Diabrotica longicornis, not only myself, but I have 
had every assistant in my department looking for them dur- 
ing their season of occurrence, but without a single indi- 
vidual having been observed. Last summer one lone beetle 
was found on the blossom. of the common sunflower, in 
my garden. We may look for it in abundance within a few 
years. It was about twenty-five years ago, in northern 
Illinois, when I found my first specimen in a corn field. It 
was a rare find in that locality at that time, but now they 
may be found there by the million. A small hymenopterous 
parasite of the San José scale, Aphelinus fuscipennis, has 
been found in Ohio this year for the first time. A single 
pupa was found by my assistant, Mr. Burgess, in the body 
of a partly developed scale from Dayton.
