Noctua, baja paired with Leucania pallens. —Until last week, I do not think, at 
any sugar operations, I ever saw Noctuce in cop.; but, on the evening of the 15th, 
I was rather startled in witnessing an unnatural alliance between N. baja and LD. 
pallens—I fancy the male was pallens. Sugaring has been very productive here ; 
on the occasion above mentioned, near the river Findhorn, I counted 766 moths on 
about 200 trees. Several moths new to the locality have turned up this season ; 
Heliothis marginata, Caradrina alsines, Hadena rectilinea and contigua, for instance, 
all at sugar. The black and red variety of Triphena orbona is just appearing. — 
Gro. Norman, Forres, 18th July, 1870. 
Note on the food-plants of Acronycta menyanthidis.—As regards the food-plants 
of this insect, my experience goes to corroborate the statement in the ‘* Hntomolo- 
gist,” as I never found the larva on Myrica gale, while I have found from 30 to 40 
on Menyanthes trifoliata and on Calluna vulgaris. In confinement I have found 
them eat hawthorn readily ; in fact, I have found that almost any species, which 
in a wild state feeds on heather or willow, will, in confinement, feed on hawthorn, 
and that almost all heather feeders will also eat willow. On hawthorn, I have 
reared successfully 8. carpini, B. callune, A. menyanthidis, &c.; and on willow, the 
above species, and L. cesiata, Anarta myrtilli, Cidariu populata, &&.—J. TRAILL, 
Old Aberdeen, August, 1870. 
Note on the larva of Miana arcuosa.—During the latter part of May, I had the 
good fortune to find the long-wanted larva of this species, feeding at the crown of 
the root of Aira cwespitosa; the pupa is to be found in the same position. The 
perfect insects appeared at intervals between June 26th and July 16th.—Jamrs 
Barty, 81, Wentworth Street, Sheffield, August 1st, 1870. 
Note on Mimeseoptilus aridus.—Some few months ago, Dr. Jordan kindly sent 
me a plume moth which had been taken by Mr. Dorville in Devonshire. (n learning 
it was Zeller’s avidus, I compared it with a specimen I took on a rock face (one of 
the ugliest I ever had to climb) at the Isle of Man, in June, 1867, and which I had 
believed to be a new species, and I found them identical. On noticing the remark in 
Ent. Annual, 1870, p. 143, it struck me that anything tending to elucidate the point 
to which Professor Zeller has called our attention might be of interest. I may 
therefore mention that, so far as I could ascertain from the rugged nature of the 
ground where I captured my specimen, there was no Knautia arvensis growing any- 
where near ; and, as Professor Zeller says of his serotinus that it feeds on that plant, 
at first down the centre and afterwards on the leaves, it may be quite possible that 
aridus is a good species.—C. 8S. Grecson, Rose Bank, Fletcher Grove, Liverpool. 
Note on leaf-folding gall-midges.—As in the Lepidoptera we meet with gall- 
making, leaf-rolling, and leaf-folding Tineina, so we find amongst the Diptera a 
large genus, Cecidomyia, the members of which are adepts in the same crafts. In 
the present lines I will confine my attention to a few gall-midges which, in their 
larval state, fold leaves, and the ceconomy of which wants further investigation. 
Throughout the summer, I have for several years past noticed in this neighbour- 
hood, yellowish larvae of a Cecidomyia in the doubled-up and incrassated leaflets of 
Rosa canina. Hach leaflet is neatly folded edge to edge, so that the upper-side of
