Southern half of State, common : much less so in the northern 

 counties. February 10-November 17. Occurs beneath bark and 

 hibernates in small colonies beneath partly buried logs. About one- 

 third of the males have the third ventral prolonged backwards in a 

 lobe, with parallel sides and rounded tip. This bears a fringe of 

 long, stiff hairs and sometimes reaches nearly to the end of abdo- 

 men. (Fig. 162, No. 1.) This lobe is also present in some of the 

 males of the next two species, but its function is as yet unknown.
