Penzance and Land's End gigantea, Schrk. Pencalenick ; W. Cornwall (D.) lutescens, F. E. Cornwall (M.) ; Bodmin ORTHORRHAPHA (continued) NEMATOCERA (continued) TABANIDAE (continued) Tipula oleracea, L. Common throughout the county and at Scilly. The frequent wet autumns in Cornwall make this pest at times unfortunately abundant, and although the damage done to crops is almost invariably attributed to the wireworm, there is no doubt that in some years, like 1904, these ' leather jackets ' cause a large amount of damage. In the winter of 1903-4, some autumn-sown wheat near Falmouth was com- pletely destroyed by this pest and the spring- sown oats in the same field were ruined. It seems probable that Pachyrrhina maculosa is at times so common locally as to be a source of considerable loss to the farmers, especially among young seeds T. paludosa, Mg. Fairly common in 1904 about Bodmin ; of frequent occurrence around Truro and Falmouth; W. Cornwall; probably fairly general in its distribution T. o:hracea, Mg. Neivjuay ; Truro; Swanpool ; Land's End; W. Cornwall (D.) RHYPHIDAK Rhyphus fenestralis, Scop. Padstow (L.) ; W. Corn- wall (D.) punctatus, F. W. Cornwall (D.) BRACHTCERA STRATIOMYIDAE Pachygaster Leachii, Curt. Very abundant in a ditch near Trescore, Porthcothan (L.) ; W. Corn- wall (D.) Nemotelus pantherinus, L. Padstow (L.) nigrinus, Fin. Padstow (L.) Oxycera Morrisii, Curt. Two specimens on a tree outside Trescore (L.) pulchella, Mg. Padstow (L.) trilineata, F. Padstow (L.) Stratiomys chamaeleon, L. W. Cornwall (D.) Odontomyia viridula, F. Padstow (L.) ; W. Cornwall (D.) Sargus cuprarius, L. IV. Cornwall (D.) Chloromyia formosa, Scop. Padstow (L.) Microchrysa polita, L. Padstow (L.) ; tV. Cornwall (D.) flavicornis, Mg. Padstow (L.) Beris vallata, FOrst. Padstow (L.) Chorisops tibialis, Mg. Padstow (L.) ; W. Cornwall (D.) TABANIDAK The Tabanidae are popularly known as Breeze Flies, Horse Flies, Gad Flies and Clegs. Though the males appear to frequent flowers and live on their nectar the females are all bloodsuckers and cause considerable annoyance to stock and more especially to horses. The larvae are not parasitic, but live in the ground, and in some species in water, and appear to be carnivorous. 2 3
