THE CLoverR SEED CHALCID 99 
In 1912, the weather conditions being favorable for the growth 
of red clover, the chalcids got another start in the southern half of the 
state. The first specimen was taken June 1 at University Farm, Saint 
Paul. This undoubtedly represented the first generation for the year. 
So few could be found that we cannot say when this generation reached 
its maximum abundance. The second generation appeared in breeding 
cages on July 5, emerging rapidly until July 9, then slowly and in small 
numbers during the remainder of the month. 
In 1912, also, observations and collections were made in the south- 
eastern part of the state, Olmsted and Fillmore counties. No data 
were secured on the emergence of the first generation. Clover heads 
collected in that region on August 8 and 9 and placed in the insectary 
at University Farm gave adults from August 19 to September 27. 
Heads collected September 11 and 12 gave adults from September 24 
to November 16. In all, 217 individuals were reared, two-thirds of 
which emerged before September 1, and these came from the heads 
collected August 9 and 10. The period of most numerous emergence 
for the year in Olmsted and Fillmore counties was probably during the 
last week of August. 
In Wadena county, in 1912, we were not able to observe the 
emergence of the first generation, but from breeding cage records and 
field collections it appears that of the succeeding generation a very few 
adults were out from August 15 to 25, then a rapid increase, a large 
number emerging until September 25, then a rapid falling off in early 
October. 
In the season of 1913 in the vicinity of University Farm, adults 
appeared June 12, a very few until June 18, then no more until July 
10. A few appeared during July and until August 18 when there was 
a sudden increase and many emerged until September 6. After that a 
few during the remainder of the month. Clover heads taken in the 
previous September in Fillmore and Olmsted counties gave the first 
adult June 12 and the last July 1. The period of most numerous 
emergence was from June 17 to June 21. 
Clover heads from Wadena county collected in September, 1912, 
gave adults in 1913, at Saint Paul, from June 11 to July 5. Nearly all 
of these appeared between June 17 and July 1, with the maximum 
emergence on June 21. 
In November, 1912, clover heads were collected at Duluth, St. 
Cloud, Winona and Mankato. Adults emerged in 1913 as follows: 
Duluth specimens, June 9 to July 1, maximum emergence, June 18. 
St. Cloud specimens, June 12 to July 1, maximum emergence, June 18.
