140 THE ESSEX NATURALIST The Camberwell Beauty Butterfly. In The Entomologist for May, 1948 Mr. A. F. Common reports that he saw a specimen of this immigrant species (Nymphalis antiopa L.) in a wood near Westcliff-on-Sea on March 26th, 1948. Another specimen was seen settled on an Oak trunk in Onsar Park Wood by Dr. I. H. Jenkins on April 10th, 1948 (The Entomologist, July, 1948). Second brood White Admiral Butterfly. To the record by W. A. Sands (Essex Naturalist, vol. 28, p. 79) of a second brood Limenitis camilla L. may be added the following from The Entomologist's Monthly Magazine, vol. 84. p. 79. One female September Ist, 1947 (D. Cox, Colchester). A second brood insect of this species was also recorded in Essex by Mathew in 1911 (Ent. Mon. Mag., vol. 47, p. 235). Continued occurrence of Coenagrion Scitulum. Mr. C. O. Hammond reports in The Entomologist for December, 1948, that he took a male and a female of this dragon-fly in its known Essex locality on May 22nd, 1948. This is the third consecutive year in which the species has been proved to occur there. In view of the fact that the two specimens mentioned above are the only ones reported for the season, it is to be hoped that collectors will refrain from taking any more specimens. Unless the species becomes much more com- mon captures should be released uninjured after identification. Essex successes in Bird and Tree Competition. In the open class of this competition organised by the Royal Society for the Protection of Birds the first prize was won by the Royal Liberty School, Romford. Netteswell Primary School obtained a Highly Commended and North Street Primary Boys, Hornchurch, a Commended. The Junior Bird Recorders' Club awarded a Salzman Prize for consis- tently good work to Mr. R. W. Arthur, of Seawick Road, St. Osyth. We have offered our congratulations to Mr. Arthur and have pleasure in publish- ing notes which he has sent us. Dipper at St. Osyth. On February 29th, '1948, I saw a British Dipper (Cinclus cinclus gularis) bobbing about and calling with a shrill zit-zit-zit in the main channel of the nearly-drained St. Osyth Millpond. On Decem- ber 18th, 1948, I again identified a bird of this species at the same place, particularly noting the dark chestnut plumage and white throat and upper breast. This time the millpond was full and the bird was on the end of the landing stage. John Cutter. Display of Kingfisher. On January 2nd, 1949, while cycling along the main Chelmsford-Colchester road we noticed a mass of flashing kingfisher- blue on the flooded River Ter. We stopped and then saw two Kingfishers— their beaks together—rising, sinking and fluttering their wings as one bird on some floating water-weed. We heard a small bell-like note as they rose out of the water and perched on a nearby branch. Here one bird offered a reddish fish to the other whose wings shivered like those of a young bird begging for food as it uttered the bell-like notes. Both birds then flew to overhanging branches farther away and were gone save for a flash or two of blue and a few more bell-notes. Reginald W. Arthur. John Cutter. Blackwinged Stilt at St. Osyth. I have observed Black-winged Stilts (Himantopus h. himantopus) on three occasions recently on the St. Osyth
