Geographical distribution (27: -2). This, tlu- InrLrost North Ainori- 

 oan l)uttcrtl\- known, is, strictly speaking, an inliahitant of the tropics, 

 but east of the great plains it is entirely at home throughout the whole of 

 our Carolinian fauna, and has invaded, especially of recent vears, many of 

 the northern states. It is fonnd throughout the Antilles and Central Amer- 

 ica and through the northern part of South America, New Grenada, 

 Venezuela and northern Brazil ; and in all this region is accompanied by 

 another form scarcely to l)e distingiiislied from it, which extends southward 

 through the Amazon region to the tropic of Capricorn. In the United 

 States it occurs in the greatest abundance in all the southern states south of 

 latitude 35°, and has been known for a long while from many of the states 

 fm-ther north. It was recorded from New York even as lonff a^o as 

 l.st;4. and it appears by the statistics of recent years that it has been 

 slowly and steadily invading the north to a greater and greater extent. It 

 is now found fixirly well established in all the states south of latitude 42°. 

 It does not appear to have extended westward very far, being proliably 

 limited by the eastern border of the great [)lains. The westernmost local- 

 ity from which it has been reported in the northern portion of its region 

 are St. Louis, Mo. (Kiley ), eastern Kansas (Snow), Davenport, Iowa 

 (Putnam ) , Wisconsin, occasionally as far north as Lake Winnebago (Hoy) . 

 This last indicates also one of tlic northernmost points from which it has 

 been obtained in its western circuit ; for in Illinois it has only been reported 

 from .\lcdo, thirty miles south of Davenport, lo. (Putnam), and Galena 

 (Bean) — though Dr. Fitch received in 1854 a specimen from Dr. J. C. 

 Harris, taken at Ottawa in this state — and in Indiana from Greensburgh 

 (Shannon) ; but it has also been taken in Michigan at Lansing (Cook), 

 even near Marquette on Lake Superior in 1885, the northernmost point 

 from which it is reported (H. Edwards), was said by Kellicott to be more 

 common in barnyards in 1888 than Pap. polyxenes, and must occur in the 

 vicinity of Detroit since it has been found in numerous places in western 

 Ontario. These are, to pass from west eastward, Amherstburgh and other 

 parts of Essex Co. (Reed, Denton, Lowe), Point Pelee (Saunders), Port 

 Lambton on the St. Claire (Lowe), and Chatham, Kent Co. (Saunders). 

 In the central portion of that part of Ontario which rests upon the lake 

 of that name, it has been found at St. Thomas, Middlesex Co. (Eccles), 

 Thedford (Watson), London (Saunders, Reed), where it is not now 

 found (Can. cnt., xix : 225), Oxford Co. in 1887 (Geddes) and Long 

 Point, jutting into the lake (Moffatt) ; while in the eastern region it has 

 been taken at DunnviUe, Haldeman Co. (Lowe), Diindas, Wentworth 

 Co. (Murray), Hamilton (Moffatt, Murray), Grimsby, Lincoln Co.
