THE ESSEX NATURALIST
Mr. G. A. Pyman tells me that he saw several specimens of the Grayling
(Eumenis semele (L.)) on a salt marsh at Lee-over-Sands, St. Osyth, on 29 July.

An unrecorded foodplant of the Holly Blue butterfly.—Some larvae taken
at Grays feeding on Lucerne produced, somewhat surprisingly, a male Holly
Blue (Celastrina argiolus (L.)) instead of one of the species which normally
feed on leguminous plants. None of the standard books gives this food
plant for the Holly Blue, but Mr. Derek Ashwell tells me that he has found
the larvae feeding on Lucerne and also on Black Currant fruits in his garden
at Bishop's Stortford.

Lepidoptera migration records for 1949.—The Entomologist for May 1950
contains the annual migration records compiled by Capt. T. Dannreuther,
R.N., which are such an interesting and valuable feature of this journal. The
records include those provided by Mr. A. J. Dewick, from Bradwell-on-Sea,
Essex. Other records of Essex migrant Lepidoptera in 1949 are those by
Mr. Dewick (The Entomologist for February 1950, p. 44) and Mr. Huggins
(The Entomologist for April 1950, p. 88).
Convolvulus Hawk Moth at Brentwood.—Mr. E. F. Williams writes that
Mr. J. S. Pond took a specimen of this immigrant moth at Brentwood on
1 September 1950.
Silver-washed Fritillary near Ingatestone.—On 14 July 1950, four speci-
mens of this butterfly were seen in a large wood within a few miles of Ingate-
stone (H. L. G. Stroyan in The Entomologist for October 1950).
The Essex Coenagrion.—In The Entomologist for May 1950, Mr. A. E.
Gardner records his capture of a male and a female Coenagrion scitulum
Rambur in south-east Essex on 19 June 1949. A description of the eggs
which were dissected out is included in the note.
Thenymphal stages of Coenagrion scitulum Rambur.—InThe Entomologists'
Monthly Magazine for April 1950, Lt.-Col. F. C. Fraser fully describes and
figures the instars of nymphs of this dragonfly bred by him from Essex females.
This is the first description which has been made from British specimens.
Coleoptera of the Colchester district.—Details of a large number of species
of beetles taken by him are given by Mr. Desmond Cox in The Entomologists'
Monthly Magazine (1946, 82 : 47 ; 1947, 83 : 104 ; 1949, 85 : 288 ; 1950,
86 : 142).
Stollia fabricii Kirk in Essex.—I recently found Stollia fabricii (Hemiptera,
Pentatomidae) in the Halstead area. I actually saw it first in 1948 but did
not identify it until this year (1950) when in June and July it was very common
on Stachys sylvatica. It is a very handsome insect of a general bronzy
colour and has a bronzy-purple spot on the anterior part of the scutellum.
The nymph, which I have also found, has the abdomen green with transverse
black bars. I also found two nymphs in Suffolk near Flatford in mid-August.
