Hastings and Dunedin, Fla., Aug. 23 Dec. 11 (W. 8. B.). 

 The Dunedin specimens were taken in tall grass on the bed of 

 an old lake, Oct. 24 Dec. 11, mating on the latter date. Scud- 

 der's type was from eastern Florida, and it is known only from 

 that State, having been recorded from various points between 

 Jacksonville, Lakeland and Pine Island. It occurs mainly in 

 moist grassy places in open pine woods and along the edges of 

 hammocks, is nowhere common, and in life is one of the most 

 handsome of the Melanopli. At Homestead and Detroit it was 

 found by R. & H. in July in the prairie-like everglades and about 

 pot-holes in the pine woods. They record females from Atlantic 

 Beach measuring 30.6 mm. in length of body, while at Homestead 

 the smaller females were but 19.5 mm.

Intermediate in size between signal us and pusillus. Pale yellowish- 

 green, brown above and on tegmina, with fuscous postocular stripe as in 

 signatus. Disk of pronotum more tectiform than there. Furcula more 

 elongate and less divergent than in signatus. Subgenital plate narrower

Live Oak, Fla., Aug. 10 (Morse). Known only from Live Oak 

 and Gainesville, Fla., the former being the type locality. There it 

 was found by Morse (1001, 40) in the scrubby undergrowth of 

 palmettoes and bushes in the damper spots of the pine woods. At 

 Gainesville ten specimens were taken August 16 by B. & H. (1907) 

 "in the rank vegetation around a flooded sink hole in pine woods."
