NOTES AND OBSERVATIONS. iB; 
One butterfly, of a delicate lilac shot-satin tint, was not in the least 
affected. My brother sent me a few Sphinges from India. After 
they had been in the relaxing box two or three days they began to 
smell putrid; an injection of about fifteen drops at once cured this, 
they have remained in perfect condition ever since and have not 
shown any sign of “grease” after ten months. For general purposes 
I have stuck to my original method as described in the ‘ Entomolo- 
gist,’ and have found it very satisfactory. I have had no opportunity 
of trying formaldehyde on “‘ Emeralds,” and I have not the slightest 
doubt that Mr. W. 8. Gilles is quite correct in warning us not to.—

Notes on RuHyYAcIONIA pPosTIcANA.—In the ‘ Entomologist’s 
Monthly Magazine,’ xxi, p. 138 (September 13th, 1884), I recorded 
among other Tortrices captured at Rannoch “5 Retinia duplana of 
our lists (Scotch form of Retinia turtonana ?)”” For upwards of thirty 
years these five specimens have remained in my cabinet unsatisfac- 
torily named, especially as Mr. C. G. Barrett in his article in the 
same magazine, xix, p. 136, so emphatically stated that we have no 
British duplana. Not long since I submitted the specimens in 
question to Mr. J. H. Durrant, who pronounced them to be 
Rhyacionia posticana ; according to Standinger this species occurs 
in Scotland, but dwplana does not. In those early days the tortrix 
in question was very rare and almost unknown in collections. It 
would be of interest to me to know if it has been taken in Scotland 
in modern times and if its life history is known. For the informa- 
tion of those who may be visiting Rannoch this year and are 
‘interested in this very fascinating group of moths, | may mention 
that I took the posticana flying in the afternoon sunshine—not in 
the Black Wood, but among the smaller scattered fir-trees on its 
outskirts—during the last half of June—A. H. Jones; Shrublands,

Lona PrEriop oF EMERGENCE OF APOCHEIMA HISPIDARIA IN 
1916.—Owing to the unusually mild weather experienced during the 
first half of February and the succeeding long spell of cold weather 
extending into the middle of March, the period of emergence of 
Apocheima hispidaria in Epping Forest has this year been an excep- 
tionally long one. I found ¢ examples on Sunday, February 13th, 
and again on Sunday, March 12th, all newly-emerged examples; and 
I have heard of captures by friends of the same insect in Epping 
Forest on February 20th and on March Ist of this year. In normal 
years A. hispidaria usually commences to emerge in Epping Forest 
round about the 18th of February and it would then be a hard task 
to find even a worn example after the end of the month.—R. T.

Harty APPEARANCE OF HYBERNIA MARGINARIA AND OF ANISOP- 
TERYX ASCULARIA.—On February 7th I took at light a specimen of 
Hybernia marginaria, and on February 8th Anisopteryx escularia on 
a paling.—H. O. Honrorp; Elstead, Surrey.
