 Dunedin, R. P. Park and Kissimmee, Fla., Jan. 1 — April 1 

 (IV. S. B.). Vienna, Va., Aug. 9 (Barber). In Indiana it occurs 

 mainly beneath loose bark and on foliage of shrubs and hiber- 

 nates beneath logs and old rails, especially along borders of 

 low cultivated fields. One pair was taken in coitu as late as 

 Nov. 20. About Dunedin it has been taken sparingly beneath 

 boards and by sifting along the borders of ponds. Not before 

 recorded from that State. Ranges from Quebec and New Eng- 

 land west to Wisconsin and Winnipeg, Manitoba, and southwest 

 to Florida and Louisiana, but nowhere common. All specimens 

 at hand are wingless.
