Distribution (18:;")). This is a Avide spread species, appertaining to 

 the warmer parts of the United States east of tlie Great Plains, though 

 occasionally taken far north, in Canada and NoA'a Scotia ; its southern 

 limit is the coast of the Gulf of ^Mexico, Avhere it has been taken in 

 Florida (Chapman, Thaxter), Alabama (Gosse), and Texas (Strecker). 

 It Avas long ago reported from Georgia by Abbot and from Carolina by 

 Petiver. Westward it extends to Arkansas (Say), Missouri (Edwards), 

 eastern Kansas (SnoAv), Fort Niobrara, Nebraska (Carpenter), Iowa (Al- 

 len, Austin, Parker, Osborn, Putnam), and Wisconsin (Hoy) ; northward 

 it has been reported in solitary instances at the Lake of the Woods 

 (Dawson), in Ontario (Saunders), Compton (Gosse) and Rouge District, 

 Quebec (D'Urban), and Nova Scotia (Jones). It is also found near Mon- 

 treal (Caulfield, Pearson) and even at OttaAva (Fletcher) ; but it is abundant 

 only in the southern states (Gosse). Edwards, hoAvever, states that it is 

 " not Acry conunon " in West Virginia, and records a case of great abun- 

 dance in northern Ohio, though Dury calls it " rare" about Cincinnati. 



Within the limits of New England it is very rare ; it may be found oc- 

 casionally upon tlie banks of the southern Connecticut, where Mr. Emerj- 

 reports that it is " not uncommon " in certain stations about Holyoke and 

 ]\Iount Tom in Massachusetts. Mr. Spragtie and I have both taken it in 

 the Xotch between Andierst and Holyoke, ^Messrs. Dimmock and Si)rague 

 on Mount Tom, and ^Ir. Dinunock south of Springfield. The only other
