A large and very handsome species that is common all along our 

 southern coast, and is distributed sparingly throughout the Mississippi 

 valley. 



Nymph. Total length 25 mm : abdomen 15 mm ; hind femur 7.5 mm ; 

 width of head 7.5 mm, of abdomen 9 mm. 



Save for the slightly larger size and a slightly darker general color, I 

 can find no diff"erences between this nymph and that ofT. lacerata 

 excepting the ones stated in the table: I find but 10 lateral setae in my 

 nymphs of Carolina, while generally there is an added shorter one 

 at the proximal end of the row in lacerata.
