SUr.KA.MILY II. OEDIPODIXvE. 289 



Lake Michigan. It is most common along the beach within one- 

 half mile of the lake, in company with Tr'tui'-roli-oftix iiniritiina 

 (Harris) and &p1t<tru</<'iiioii wyomingianum (Thos.), though a few 

 specimens were taken on sandy ridges five miles from the lake 

 shore. It has a quick, short flight, and always chooses a bare, 

 sandy spot on which to alight. Unless it is carefully marked 

 down it is then very difficult to distinguish, since its colors har- 

 monize so perfectly with its surroundings. By keeping an eye on 

 it and stealthily approaching it can readily be taken by throwing 

 the net quickly over it just as it is in the act of rising. The male 

 makes a slight rattling sound as it flies, but the movement of the 

 female is noiseless. The majority of the specimens taken had the 

 inner wings a bright red at base, though variations in color, from 

 light yellow to deep red, were noted. It probably occurs in sandy 

 areas throughout the State. 



In Florida P. fcncxtnilis has been taken by me at Ormond, San- 

 ford, Little River, Ft. Myers, Sarasota and Dunedin and is record- 

 ed from numerous localities by other collectors. About Dunedin 

 it occurs in small numbers in both nymph and adult stages 

 throughout the winter, frequenting sandy roadsides, old fields and 

 orange orchards, often in company with s'. ///. j>i<-f<t, ('. r. diistrfi- 

 Hor and other ammophilous species. 



The known range of P. fcncstraJis extends from Maine to 

 Minnesota and northwestern Nebraska, south and southwest to 

 southern Florida, Mississippi and northern Texas. It is not 

 known from the southern keys of Florida, but Relm I 1 !>(>!), 204) 

 records it from Guanabacoa and Havana, Cuba. Though Saussure 

 (1884, 104) says it occurs "in Canada extensa," and Scudder 

 (1900) gives its range as "U. S. and Canada east of Mississippi 

 River," it is not recorded from that country in any of Walker's 

 papers nor is it definitely recorded from Ohio or Michigan, though 

 it should occur in both states. 



Of its occurrence in Xew England Morse (1X!)7, 112 1 says: 

 "This is a common and widely distributed species, found nearly 

 everywhere on sandy spots in southern Xew England, and prob- 

 ably throughout the entire district. On the seashore il is some- 

 times associated with T. I/KII iHnni, (Harr.). It is usually plen- 

 tiful where it occurs, though often very local in consequence of its 

 habitat. When disturbed it flies but a short distance, often only 

 a few feet, the male producing a very slight, scarcely noticeable, 

 crepitation." Vestal (19KV) states that in "the bunch grass of 

 the sand prairies of Illinois no species of the Oedipodino 1 but 

 Xl>1i<ir<if/aiion outnumbers it," but in Minnesota Somes (1914)
