34 A NATURE WOOING. 



to me a mystery, for I see no sign of mosquito or 

 other dragonfly tid-bit in the cold raw air. 



Of butterflies I note another old friend, the giant 

 swallowtail, Papilio cresphontes Cram., but it, too, is 

 propelled onward by the stiff breeze too rapidly for 

 me. Two worn and be-draggled specimens of the 

 buckeye butterfly, Junonia >ccenia Hub., alone are 

 captured. Both it and cresphontes range as far north- 

 ward as northern Indiana, though both are scarce in 

 that State. 



Over a sandy stretch in the old orchard I find the 

 locusts common ; among them the ArpJiia taken yester- 

 day, as well as a handsome, parti-colored species, 

 Scirtettica picta Scudd. The male of this usually 

 flies a long distance when flushed, making, while on 

 the wing, a noise like the buzzing of a very angry 

 bumble bee. The female is more sluggish, and noise- 

 less in its flight. The common, green-striped grass- 

 hopper of the north, Chortophaga viridifasciata De 

 Geer., is also present in numbers on the sand covered 

 earth. Its hues are, however, so different that I do 

 not recognize it, and think it an undescribed form un- 

 til I reach the house and consult Scudder's table of 

 variation of the northern and southern forms. On a 

 patch of green weeds I find a pair of wingless, bright 

 green locusts the tegmina being represented only 

 by narrow, oblong, whitish yellow scales. They leap 

 clumsily when disturbed. They prove to be examples 

 of Aptenopedes spJienarioides Scudder, a species
