182 THE WAYS 



easily stirred. Driving one morning within an 

 hour after sunrise across the sandy plains of Nan- 

 tucket, along a road fringed with a row of stunted 

 pines some fifty feet from the track, a contmuous 

 stream of Blue-eyed Graylings (Cercyouis alope) 

 arose, stirred from the low tops of the bordering 

 pines by the rumble of our wagon-wheels ; none 

 were to be seen either before or behind us, but 

 on either side they constantly arose as we reached 

 them, and, wafted by the wind, sank drowsily to 

 the earth. Just before nightfall, at the proper 

 season, one may readily discover the American 

 Copper (Heodes hypophlaeas) or the Clouded Sul- 

 phur (Eurymus philodice), clinging head upward 

 and with droo23ing wings to any common herbage ; 

 or watching the Spring Azure (Cyaniris pseudar- 

 giolus) as it rests on a bough may observe it, as a 

 heavy cloud obscures the sun, drop fluttering to 

 the ground to alight upon a blade of grass in some 

 concealed si3ot beneath the shrub it had left. Gosse 

 states that in Jamaica the Heliconians (Apostra- 

 phia charithonia) assemble in a swarm before sun- 

 set and huddle together on the stem of a certain 

 plant for the night; is it not 230ssible, however, 

 from what we now know of this butterfly, that 

 these were simply males assembling about a chrys- 

 alis of a female ?
