Porter and Marion counties, Ind., Aug. 22 — Sept. 12. Istok- 

 poga, R. P. Park, Ft. Myers and Dunedin, Fla., Nov. 17 — April 

 14 (W.S.B.). Hessville and Mineral Springs, Ind., July 24 — 

 Sept. 4 (Gerhard). Scarce in Indiana. Frequent at R. P. Park 

 and Dunedin, Fla., on Pteridium aquilinum (L.) and other ferns 

 in and about the margins of moist dense hammocks. A Euro- 

 pean species ranging in this country from Quebec and New 

 England west to Wisconsin and British Columbia and south to 

 Florida, Texas and Mexico. As the specific name indicates, 

 it occurs mainly on ferns, though often swept from other 

 vegetation about the margins of ponds, and in Florida hiber- 

 nating beneath boards and piles of weed debris in moist places. 

 The color varies to some extent, northern specimens being 

 darker brown than those from the south, with the basal angles 

 of pronotum pale.
