202 MONOGRAPHIA NOTIOPHILON ANGLIC, 



moth, but wliich one of the numberless thousands on the wing 

 to select for an object of capture, as their flight was so rapid 

 and irregular, that the eye became bewildered with their 

 motions, and, like the Gyrini, they were lost in the mazes of 

 their evolutions. After securing what specimens I wanted, I 

 could not help watching the scene before me ; and, as in the 

 study of all nature's works, the trouble, or rather the time 

 spent, was more than amply repaid ; for sudden as their 

 appearance had been, their disappearance was equally so, 

 when, as with one general consent, about half-after eight, 

 they again settled ; and their flight for the morning being over, 

 scarce a solitary specimen w^as anywhere to be seen. The 

 moths flew about three or four inches from the ground, and 

 apparently very seldom alighted, but thi-eaded their way most 

 dexterously amongst the long culms of the grasses. I reached 

 home, not only pleased with my capture, but infinitely more so 

 with the interesting habits of this insect ; and I regret that I 

 have not had an opportunity of again witnessing them. The 

 species, though common hereabouts, has been considered rare 

 in the south of England, probably from our being ignorant of 

 its habits.
