SCIENTIFIC NOTES AND OBSERVATIONS.

the usual hybernation of the species ? or was it a larva which through 

 misfortune was compelled to lengthen out its feeding stage until the 

 autumn ? Mr. AulJ, some time ago, exhibited at the South London 

 Entomological Society, a larva of this species which had so gone over 

 the summer, and stated that several of the others he had taken the 

 previous autumn had done the same. He was not, however, he tells 

 me, successful in breeding the imagines from these. Perhaps others 

 who have bred the species would relate their experiences, as it would 

 be interesting to know if this fact has been noticed before. Personally 

 I am much of the opinion that the larva I found was one that had 

 prolonged its larval stage, and not one which had hurried up. It is a 

 very lethargic and slow- feeding species, often staying on the same spot 

 for days, and is very seldom seen stretching out its head in the usual 

 fashion of Geometers. If it does sway the fore part of its body, it is 

 in the early morning, when the sun shines directly upon it, and it is 

 then I judge that it eats the little it seems to require. All those 

 species which have produced two broods in a season are, even when 

 they hybernate as larvfe, active, and eat rapidly and very freely. —

EUPITHECIA SUCCENTURIATA AND E. SUBFULVATA. Eupitlu'cict SUCCCH- 



turiata occurs here sparingly but does not vary, and I have never seen 

 an E. suhfidvata here. I intend to try for the larva;* of the former in 

 a feAv days, and if I breed it, will note the results. — T. Maddison, 

 South Bailey, Durham. Scptoiiht-r VSth, 1895. 



I have never taken in this neighbourhood a specimen of E. succoi- 

 turiata, but I have bred E. snbfidvaia and its var. o.rydafa every 

 season for the last 10 or 12 years, from larvae which I collect from 

 yarrow (Achillea viillefoliiwi) and tansy [Tanacetum vuli/arc), in 

 October. I have never seen a specimen of E. suhfidvata approaching 

 in the slightest E. sucrmturiata. The specimens of A', suhfidvata which 

 I have bred are much larger than any specimen of E. succenturiata 

 that I have seen. I find the best way to take the larvfe of E. snhful- 

 vata is to look over the yarrow after dark, Avith a lamp. — J. Finlay, 

 Morpeth, Se]>tembcr llth, 1895. 



The remainder of the pupte mentioned in my note [ante, p. 43) 

 yielded E. suhfidrata. I am taking the larvae on the same tansy plant 

 now, and will send a further note anon. — ^Richd. Freer, M.B., Rugeley. 

 October, 1895. 



Scoparia atomalis from Eskdale. — The Scoparia that I took in 

 Eskdale, in 1887, which I suppose to be S. atomalis, is certainly very 

 like a small ambigiudis, but the costa is more rounded, the fore^ wings 

 slightly narrower, and the elbowed line less indented than in normal 

 S. amhigualis. The hind wing, also, is more hollowed out on the 

 hind margin. — H. H. Corbett, M.R.C.S., 19, Hallgato, Doncaster. 



Colias edusa : will Mr. Frohawk explain ? — I was recently 

 looking up the description made by Mr. Frohawk of the egg of Colias 

 edma {Entnui., x\v., 202-203). In describing the eg'g, he remarks: 

 " When first laid it is of a yellowish pearl -Avhite, gradually becoming 

 deeper in colour, approaching creamy-yellow. When about twenty-four 

 hours old it assumes a light copper-pink hue, from which it gradually 

 deepens into a rosy orange-pink, the high lights glistening with blue, 

 the orange colour showing in shadow." Again, in describing the young 

 larva, Mr. Frohawk writes : "It then measures Jg of an inch in length,
