of the orange tree growing in sonic abundance on the banks of a lirook 

 behind the town of Carbonear. A few examples onl\' occurred, but from 

 its minuteness and dull hue it may be easily overlooked. Vet the area of 

 the upper surface, though dull, has a rich purple flush in some lights. 



Lyacna Aster. W . H. I'aIw. I'his species, which 1 had supposed to 

 be our English Argus, is far more common than the preceding, in the 

 summer of 1834 it was nearly as abundant as the little Orange-brown on 

 Carbonear Island, where every step aroused numbers of these bright little 

 creatures from the grass to sport in the sunshine. It was surprising to see 

 how much the beams of the sun, reflected in every direction from their 

 lustrous wings, added to the life and gaiety of the scene. 1 have found 

 the species not rare also on Bake-apple Marsh, during July and August, 

 the hottest and brightest part of our short summer. 



Lye. Couperi. Grote. On the other hand I am acquainted with but a 

 single specimen of this species, which 1 distinguished as the Silver Blue. 

 This was caught on Carbonear Island, on the loth of July. 



Lye. Aqiti/o, Boisd. The Lead-grey Blue. This too is fouml on Car- 

 bonear Island in July, but by no means commonly. 



The above-named are all the butterflies that I have actually taken in 

 Newfoundland. But there are doubtless some that escaped me. In May, 

 1835, ^^ ^ ^^'^^ o^"^ Flagstaff Hill, about a mile from the town of Carbonear, 

 I saw a small butterfly, strange to me, red, with black spots. It may have 

 been Meiitcea or ChrysoplnDius. \ observed it five or six times during an 

 hour that I remained there, but, though it fiew near me, I could not 

 catch it. 



ON THE GENUS AGROTIS. 



BV A.- R. GROTE, A. M. 



In the Reports of Dr. Harris and Prof. Riley and some other Suite 

 Entomologists, the structural characters of the genus ^^i.vt^/' as- are not given. 

 and the term is evidently loosely applied Xo cover certain Noctuidie known 

 as " cut-worms." In Dr. Harris's Report, as I have shown, the moth 

 Hadena devastatrix (the Agrotis devastator of Brace) is considered to be 

 an Agrotis, while Agrotis C/andestitia, which has the structural characters 

 of Agrotis. is referred to the old Linnean genus Noctua. now without
