128 NOTES—ORIGINAL AND SELECTED. district, a parish sadly neglected by those interested in the natural history of Essex, whether their favourite subjects be birds, fishes, or insects.—Henry Laver, F.L.S., Colchester, October 2nd, 1903. INSECTS. Calosoma sycophanta, L.—Master R. H. Stevens recently brought up to the museum, and presented to me, a fine specimen of this insect, the rarest, largest, and most beautiful of the British Carabidae, or Ground-beetles. It had been caught at the end of July by his father, Mr. E. Stevens, on the site of a new Church, of which he is the architect, now being built in Half-mile Lane, Northwood, near Pinnar, Middlesex. Mr. Stevens writes that the beetle was crawling on the grass by his temporary office, and at once attracted his attention by its brilliant colours, unlike any insect he had seen before. C. syco- phanta is usually found on the coast, and the specimens have been supposed to be immigrants from the Continent; its occurrence so far inland is, therefore, remarkable and worthy of note here, although it is not an Essex specimen. Curiously enough, another specimen is registered this month in the Ento- mologists' Record, by Mr. W. H. Bennett, F.E.S., who found it in August, at Battle, in Sussex, seven miles inland.—W. Cole, September, 1903. Sirex gigas at Buckhurst Hill.—Among the curiosities of the gnat visitation about the middle of August was the production to me of a specimen of this insect, which had startled a maid-servant by flying to the light in her kitchen. Her mistress promptly identified it by a picture in a daily paper as one of the "mosquitoes" which had rendered night hideous to them for a week or more. As the Sirex was a fine female, measuring about two inches, with a practicable-looking, sting-like, ovipositor, the ladies' alarm at the possibility of a swarm of such midnight marauders was apparently justified!—W. Cole. Locusta viridissima.—A female example of this fine Orthopteron was brought up to the Museum, taken on the banks of the Thames near Purfleet, in August last. This insect is probably far from uncommon on our coast, but is very rarely detected, in spite of its large size; its colour and habits very effectively favour concealment.—W. C.
