 A HISTORY OF CORNWALL widely distributed but scarce among the woods in the east of the county. Symmoca quadripuncta has twice been sent in from Falmouth, where it may have been introduced. OECOPHORIDAE Carcina quercana was reported by Marshall as abundant in East Cornwall. In 1905 it was common in several of the oak woods in the north-east of the county, at Liskeard, and at Doublebois. One specimen of Chimabache phryganella was taken by Baily at Paul near Penzance. C. fagella is in most years sparingly scattered in the woods along the southern half of the county. Depressaria costosa is probably widespread, but is most plentiful among furze in the west and at Scilly. D. umbellana occurs about Truro and in the Land's End district, and was taken in 1 904 at Boscastle. D. assimilella has been taken about Menheniot. The larvae of D. llturella were found by Atmore on the heads of knapweed about Penzance. D. arenella is locally abundant throughout the county. D. propinquella occurs in Marshall's list, and has been taken lately near St. Germans and at Boscastle. D. subpropinquella was captured in the Land's End district by Dale. D. hypericclla is in Daily's list from Godolphin. D. ocellana is nowhere common, but has been taken on the Lynher and on sallows near Truro, and has been reported from the Gannel near Trevemper Bridge. Three examples of D. yeatiana were obtained by Baily at Paul. D. ahtroe- menana is often plentiful on hemlock throughout the county. The larvae of D. angelicella are often abundant in the west, and especially about Hayle, in the screwed-up leaves and tops of angelica ; the moths themselves are at times common. D. purpurea is of frequent occurrence in the east, but rare in the west; in 1901, however, almost every plant of common chervil on the south side of Bishop's Wood, Truro, was attacked by the larvae. D. cilulla is widely distributed in the county, but is probably local. D. applana has also a wide range, and is in places very common. D. rotundella has been taken at the Land's End by Dale, and at Looe by Thomas. D. badiella was obtained near the Land's End by Dale and subsequently by Baily. D. chaerophylli is occasionally seen about Liskeard, and has been captured at Looe. D. pimpinellae was taken by Jenkinson at St. Mary's, Scilly, in 1877, and in the Looe valley in 1904. Atmore found the larvae of D. pulcherrimella sparingly on the umbels of Bunium flexuosum at Penzance. D. hcracliana is widely distributed, and on the whole common ; it is well established at Scilly. D. nervosa is abundant in the Land's End district, and has been taken at Truro and at Newquay. Harpella geoffrclla is not uncommon in overgrown hedges in East Cornwall. Oecophora oliviella occurs occasionally as far west as Falmouth, but is evidently scarce. 0. sulphurella is common locally along the south and abundant in the west and in Carnanton Woods, St. Columb ; it has also been taken at Scilly. Acompsia lambdella has been bred from full-fed larvae found on dead gorse at Perranporth. A. angustella has been taken between Launceston and Callington, and A. minutella at Looe ; while a single example of A. tripuncta was captured by C. U.Tripp near Altarnun. A. unitella was fairly common to the south of Liskeard in 1901. A. panzer ella has been taken by Marshall about Botus-Fleming. A. pseudo-spretella occurs over the whole county, including Scilly, and is often abundant in outbuildings. A.Juscescens is locally fairly common in the east and at Scilly, and has been taken at Truro. ELACHISTIDAE Several specimens of Coleopbora fabridella were captured on St. Mary's, Scilly, in July, 1903, and one in the Lynher valley the same year. One specimen of C. deauratella was obtained by Baily near St. Burian. C. albltarsella has been bred from larvae found by Tregelles on ground-ivy at Perran- well. In 1904 the larvae of C. alcyonipennella were common on knapweed on the Scawswater road, Truro. C. nigricella has been taken by Atmore at Penzance and by Jenkinson at Scilly. C. gryphi- pennella has been bred from larvae found on the leaves of the wild rose near Ellbridge. The larvae of C. vim'metella were abundant on willows near Truro in 1 900. C. fuscedinella has been bred from larvae on hazel from Kilkhampton. In 1905 they were abundant on the elms in Tregoll's Road, Truro. A single example of C. lutipennella was taken by Perkins at Heligan. Colonies of the larvae of C, solitariella are not uncommon in the east and north-east on stitchwort, but are rarely seen in the west. C. laricella is fortunately not so abundant anywhere in the county as to do very serious damage to the larch woods, but occasionally one sees the delicate young needles turning brown and the portion of a tree putting on the scorched appearance that is characteristic of its attack. C. juncicohlla is not uncommon near Altarnun. C. anatlpennella is occasionally taken about Falmouth and Penzance. The larvae of C. ibipenntlla are not uncommon occasionally on birches in the Upper Tamar district, but they are difficult to rear. G. currudpennella has been taken by Tellam near Bodmin Road station. The larvae of C. dlscordella were common at Tresco, Scilly, in 1879, and those of C. lineolea on black ballot in the Poundstock district in 1904. C. niveicostella has been 22 4
