RANGE OF BROODS IN ORDER OF FUTURE APPEARANCES. 35 
Throughout the districts where the two broods mentioned approached 
each other or overlapped, the records of L883 are necessarily somewhat 
uncertain, as it was not always possible to determine to which of the 
two broods particular swarms belonged. This applies notably to locali- 
ties along the Ohio River near the Mississippi and along the Mississippi 
River from the mouth of the Ohio northward; also the areas in north- 
ern Georgia and Alabama. The records obtained of Brood VII during 
the present year should largely correct the unavoidable errors made in 
separating Broods VII and XXII in 1885.
