Elaphomyces variegatus Vitt. In a pine wood, Redgrave Sept. 1931 (A.M.). T h e table below shows the number of species of Fungi recorded for Suffolk and listed in these Transactions compared with the approximate number recognised as British. No local records of the Protomycetes (bacteria, yeasts, etc.) are at present available ; and the so-called slime-fungi, now known as Mycetozoa (fungusanimals) of which 100 species have been recognised in the County, are also omitted.

ON THE TIDE-MARK.—A visit to Walberswick on 31 August was interesting, for the Tide-mark consisted mainly of Duckweeds and chiefly Lemna gibba, with only Freshwater Snails. I see the Rice Grass Spartina Townsendi has spread to the Blyth estuary, where I do not remember noticing it before [cf. Trans, vi, 124.— Ed.]. Great quantities of Insects were being washed ashore at Dunwich, Walberswick and Covehithe on 16 August: Ten species of Ladybirds in thousands, mainly Coccinella 7-punctata, with C. ocellata and the Blythburgh Wood C. 4-punctata, waterbeetles, flea-beetles Halticid.ce, a species of Cassida and various Weevils ; the Shield-bugs included many Eysarcoris punctatus, L. [surprising ; very rare in Suffolk ; whence came they ?—Ed.], Palomena prasina and Troilus luridus, along with Corixa Waterboatmen, and Homopterous Froghoppers ; some Chrysopa Lacewinged-flies ; one Blue Butterfly Lycanalcarus ; one Grasshopper Conocephaltis dorsalis, of the extremely long-winged form Burri; also there were Syrphid Hover-flies, Eristalis Drone-flies ; Vespid Wasps, winged Ants, Bumble-bees and both workers and drones of Honey-bees Apis mellifica, L., and several kinds of Saw-flies, that of the Turnip the injurious Athalia spinarum, F., being the most abundant.—E.
