A single paratypic female has been examined in addition to the 

 types. It is very slightly larger than the female type, but otherwise 

 inseparable. 



The three specimens secured were taken from a marsh}' sink-hole in 

 pine woods. 



Xiphidion fasciatum De Geer. 



A series of twenty-four individuals represent this widely distributed 

 form, taken as follows: Jacksonville, August 11, two males, three 

 females; Gainesville, August 16 and 17, three males, four females; 

 Cedar Keys, August 15, three males, eight females; Fairfax. Barnwell 

 County, S. C, August 10, one male. 



The environments represented are a city lot (Jacksonville), under- 

 growth in pine woods and sink-hole in the same (Gainesville), and open 

 marsh (Cedar Keys). 



Xiphidion nigropleurum Hruner. 



Sixteen individuals are referred tentatively to this species, as there 

 exists a possibility that one or more distinct species are included in the 

 Florida material. The localities represented are: Gainesville, August 

 16, one female; Pal^lo Beach, August 11, one female; Cedar Keys, 

 August 15, seven males, seven females. 



\\lien compared with Nebraska and Indiana males of undoubted 

 nigropleurum the Cedar Keys individuals are as a rule larger; all belong 

 to the brown form described by Blatchley," with the pronotum very 

 dark mesad. The tegmina are as rule somewhat shorter than in 

 typical nigropleurum males and the cerci are slenderer and slightly 

 more produced, ^'ariability in the divergence of the apices of the
