Amblycorypha floridana floridana Rehn and Hebard (PI. XI, fig. 33;

Our previously expressed belief that this foim was but a south- 

 em geographic race of ohlongijoUo? we are now in a position to dis- 

 prove, sufficient material being m hand to show the proper relation- 

 ship of these two and other forms. The specimens from Thomas- 

 ville, Georgia, then supposed to be intermediate between floridana 

 and ohlongifolia are intermediates, but not between those forms, 

 instead connecting true floridana with a northern subspecies of the 

 same stock, which in its turn is perfectly distinct from ohlongi- 

 folia. This northern race we are here describing as A. floridana 

 carinata. Both it and ohlongifolia occur typically at localities 

 where the ranges of the two forms overlap. The differential 

 characters of ^. /. carinata are given under that race. 



The typical race of this species ranges from Big Pine Key and 

 Detroit, southern Florida, as far north typically as Jacksonville, 

 Fernandina and Atlantic Beach, in the same state, westward as 

 far as eastern Texas (Dickinson and Virginia Point), intergrading, 

 in the Atlantic coast region at least, into the northern subspecies 

 {carinata) over an extensive area covering from southern Georgia
