{HE CLOVER-SEED MIDGE, 
(Cecidomyia leguminicola.) 
Quite serious complaints came to me concerning this insect, princi- 
pally from counties lying north of the central portion of the State. It 
was not noticed at all in this vicinity, and so far as I know has never 
been found here or in the southern part of the State. Last year it was 
quite destructive in the same region reported from this year. 
Definite facts as to extent of injury were not to be obtained, yet good 
farmers reported it as destroying a large part of the crop in their sec- 
tions. 
THE MAY BEETLE. 
(Lachnosterna fusca.) 
The larva of this beetle has destroyed a large portion of the sward 
on the university campus during the present summer. The attack 
began some three years ago and has become worse each year, until this 
season a large part of the lawn was left bare and brown, not even the 
first growth of bluegrass coming to maturity. From the spots where 
attack is most severe the sod can be rolled up in bundles. Clover is 
not injured and is consequently spreading spontaneously over the Jawn. 
Examinations frequently showed as many as a dozen grubs to the square 
foot. There were three broods plainly to be noted; the two-year and 
one year were the most numerous, there being comparatively few grubs 
from eggs laid the past spring. 
A large number of examinations showed no case of disease. Grubs 
began descending to winter quarters about September 20, but October 
20 there are yet quite a number to be found. They were reported at 
work in lawns and strawberry gardens from many localities around the 
city, but were nowhere so numerous as here. 
PTEROMALUS PUPARUM AND APANTELES GLOMERATUS. 
A few observations on these two parasites may be of interest. Many 
specimens of each were bred. P. puparum issued on an average in fif- 
teen days from date of ovipositing. From one pupa of the Cabbage 
Worm I bred fifty-two flies and from another one hundred and eleven. 
These last issued in just sixteen days from the time the females ovi- 
posited. This I considered a remarkable number to issue from one 
pupa, but of the fact there is not the possibility of adoubt. I observed 
three of the females ovipositing in one larva on the afternoon of August 
24, These I watched for some time, intending to take the larva when 
they had done with it, but as they were still at work late in the after- 
noon I marked the spot and visited it the next morning to find a pupa 
formed. From this issued the (lies, as noted above. In two instances
