Dunedin, Lake Okeechobee, Cape Sable and Key West, Fla., 

 Feb. 23 March 26, nymphs only (W. 8. B.) ; LaGrange and Big- 

 Pine Key, Fla., September, adults (Davis.) At Dunedin I took 

 a single nymph, March 20, by beating the Florida bnttomvood, 

 C'onocarpus erecta L. on Hog Island. This is also a West Indian 

 species but is recorded from a number of stations in the southern 

 third of Florida, where it occurs in the nymph singes during the 

 winter and spring months and evidently reaches maturity about 

 June 1st. Dunedin is its most northern known locality. 



AREA AND LIFE ZONES COVERED. 



As has been noted on page three this work deals primarily 

 only with those species of Orthoptera known to occur in the 

 United States east of the Mississippi River and in Canada east of 

 the 90th Meridian. However, many of the species of which it 

 treats range over a much wider area to the north and west and a 

 number of them have their principal distribution west of the 

 Mississippi, the prairies and sand areas of Illinois and Indiana 

 comprising the eastern limits of their range. 



All of the recognized Life Zones of the United States and their 

 characteristic faunas are represented in the area covered. The 

 student must bear in mind that the fauna of no one of these life 

 zones has a definite sharp and fixed boundary line, but Uiat each 

 overlaps and merges with the one above and the one below. More- 

 over, aside from those of the Hudsonian and Tropical /ones, but 

 few of the species of Orthoptera are limited to any one zone and 

 some of them, as Conoceplniliis fasciatus (DeGeer), occur in all 

 the zones. Mentioned in order from the most northern, these life 

 zones and faunas are as follows : 



HUDSONIAN LIFE ZONE. Of the area treated this /one includes 

 all of Labrador, Newfoundland, New Brunswick and Quebec, 

 eastern Nova Scotia, the northern portions of Ontario and New 

 England, the northern Peninsula of Michigan and isolated areas 

 on the summits of the higher mountains of Xe\v York, Pennsyl-
