Bradycellus sharpi Joy A d d e d to the County list by Nash (1978), this species was considered to be apterous until the discovery of a brachypterous specimen by Hammond (1969). My discovery of two full-winged examples in Suffolk is therefore of interest. The first, a female, was swept from track-edge Vegetation, Felshamhall W o o d (TL 9357) on the 12th September, 1977; the second, a male, was f o u n d with eight apterous specimens under the loose bark of a log by a pond in the same wood, on the 4th March, 1979. The determinations of both specimens have been confirmed by Dr. M. L. Luff. *Masoreus wetherhalli (Gyllenhal) A very local species of open, usually sandy, habitats, seldom found far away from the coast. O n the 7th July 1979, I took a Single example of Masoreus under a fallen fence post on the Icklingham Plains (TL 7673), Suffolk. Dromius angustus Brülle D. angustus, recognised as a British species by Champion (1908), was first recorded from Suffolk by Elliott (1936) on the strength of three Morley records. T h e earliest refers to a male, beaten from alder in Cutler's Wood, Freston, in August 1904. Morley had provisionally identified the specimen, on which this record is based, as D. meridionalis Dejean, and then submitted it to E . A . Newbery who re-identified it as D. agilis (F.), and according to Morley's entomological diary for 1904, commented in litt. 22nd October 1904, that if it was not agilis then it was angustus, a species he had always held to be British. Morley decided that the specimen was after all angustus in 1936. I have examined the specimen, labelled in Morley's hand '22 viii 04' and also rather confusingly (probably in 1936) 'D. angustus, Brul E . A . N . 22 x 1904 New to Brit.', and can confirm that it is agilis and not angustus. Two other specimens of 'angustus' in the Morley Collection correspond with the 1932-3 Fritton and Blythburgh Wood records referred to by Elliott (I.e.). One labelled '29 ix 32 Fritton sugar' is agilis, the other labelled '5 ix 33 Blyth Wd dead b e e c h ' is meridionalis (teste M. L. Luff). T h e o n e other specimen in Morley's series of angustus labelled '25 v 49 beat oak Beiton H t h ' [TG 40] is the true angustus. I am in no doubt that this specimen is one referred to by Burton (1949) in these Transactions. A specimen in the C. G . Doughty Collection at Ipswich Museum labelled ' B r a n d o n 19/5/36' and thought by Doughty to be meridionalis is the earliest record of angustus I can trace for Suffolk. The species appears to be widespread in the County, and Messrs. D. R. Nash ( D . R . N . ) and C. S. Barham ( C . S . B . ) have kindly provided the following records: 18.iv. 1960—several specimens, Tunstall [TM 15] C.S.B.; 17.i. 1971, 23.iv. 1972—Single specimens, Hollesley H e a t h Nature Reserve (TM 345 467) D . R . N . ; 10.x. 1971— Single specimen, Tunstall (TM 380 559) D . R . N . ; 25.viii. 1974—Single specimen, Gazeley [TL 76] C.S.B. T o these records I can add: 13.xi. 1977— C a v e n h a m Heath Nature Reserve (TL 7572) H . M . Trans. Suffolk Nat. Soc.
