 INSECTS E, tetraquetrana has been reported by Baily from Paul, and a single specimen was captured at Boscastle. E. similana was taken by Pearse near Doublebois. E. pflugiana was found by Marshall in the east of the county, and was fairly common about Stratton in June, 1904. E. brunnichiana was obtained by Tellam near Withiel a few years ago, and is said to be plentiful at times in that neighbourhood. E. turbidana was taken by Marshall at Cargreen, and has occurred near Bude. Three examples of E. bilunana were captured by Baily at Paul. E. solandriana was found by Marryat at Looe, and has been reported from Newquay. E. semi/uscana is not uncommon locally in the ea^t and south-east of the county. E. scopoliana and E. cana were taken sparingly round Penzance by Atmore. Hemlmene alplnana has been sent in from Liskeard. H. petiverella is generally distributed and fairly common all over the county, including St. Mary's and Tean, Scilly. H. simp/iciana occurs near Newquay, and in 1902 was common. Atmore took Lipoptycha plumbana near Penzance, and it was found last year at Wanson Mouth, Bude. Pammene rhediella is not uncommon in the east about hawthorn, but is a rare casual elsewhere. Two specimens of P. splendidulana were seen and one captured at St. Germans in May, 1902. P. argyrana is at times fairly common on broad hedges and the outskirts of woods in the east of the county, but apparently unknown in the middle and west. P. spiniana appears to be widely distributed, but somewhat local and scarce. It has not been reported west of the Falmouth district. P. regiana was found by Atmore sparingly on the trunks of sycamores about Penzance. Atmore took a single specimen of Laspeyrtsia ianthinana near Penzance in July, 1886. L. perlepidana is represented by two somewhat worn specimens taken by Pearson near Hayle. L. internana appears to be confined to East Cornwall, where it has been obtained by Marshall and others. The larvae of L. compositella appeared on some seeding clovers in the neighbourhood of Wadebridge in 1897, but has not been seen there since 1901. The damage was very slight, and confined to a few small patches. L. nigricana is widely distributed over the eastern part of the county, but is rather scarce. It has not been taken west of Liskeard. L. legu- minana was obtained several times at Falmouth by Pearson and others between 1899 and 1902. In some seasons L. ulicetana is most abundant about furze throughout the county, including Scilly. In 1904 it was remarkably scarce, but was very plentiful in 1905. Carpocapsa pomonella, the codlin moth, is in some years one of the most destructive pests on the apple crop in the county. The females appear about the middle of May or a little later, and attach their eggs for the most part singly to the skin of the swelling fruit. The emerging caterpillars eat their way straight to the core of the young apple. Though often abundant this moth is not much seen on account of its retiring habits. The larvae of C. splendana are occasionally plentiful in acorns in the north-east and east of the county, and have been found as far west as Falmouth. Beech nuts are at intervals attacked by the larvae of C. grossana, but the insect is rarely taken. Epinotia aurana is not uncom- mon throughout the county on the outskirts of woods and the broad overgrown margins of country roads. E. albersana has been bred at Truro from larvae taken in the folded leaves of honeysuckle. Plums have been twice sent in from the east of the county containing the larvae of E.funebrana. E. hypericana was taken by Baily on more than one occasion about Penzance. TORTRICIDAE Rhacodia caudana is generally distributed about woods and streams throughout the county, but is rather scarce. Acalla cristana occurs locally as far west as Doublebois and Newquay. The beautiful variety fulvocristana, Steph. has been taken on the banks of the Lynher. A. hastiana is evidently scarce, but has been thrice taken in the neighbourhood of St. Germans. A. rufana is occasionally obtained in dense irregular hedgebanks about Saltash and Callington, and A. sponsana appears to favour the deep lanes of the same district, especially in the vicinity of Ellbridge. A. literana has been found very sparingly in woods by the side of the Tamar and about Poundstock. A. boscana has been taken in the gardens along Tregoll's Road, Truro, and near Penzance. A. mixtana seems to be limited to the Luxulian valley. C. logiana is represented by two specimens of the variety trigonana, taken by Baily at Paul in 1 893. C. variegana is generally distributed, and as a rule common along hedgebanks and narrow strips of wood. C. permutana was reported from East Cornwall by Marshall. A. schalleriana is scarce and evidently local. It has been recorded from the east of the county, from Truro and from Penzance. One specimen of A. comariana was taken and several seen by Ilott over a strawberry bed at Nance, near Truro. A. contaminana appears almost everywhere about the Tamar and Lynher, and Baily reports three specimens from the Land's End district. A pale form seems to replace the type about St. Germans. A.ferrugana has been reported twice from birches in the upper Tamar district, and one was captured last year in the Lynher valley. A. aspenana has been recorded by Jenkinson from Scilly. A. holmiana is generally distributed and common along well-covered hedgebanks and in neglected orchards. Two specimens of the northern species Philedone gerningana were taken by Baily at Paul. The very local Epagoge grotlana is recorded by Marshall from the east, and by Jenkinson from Scilly. Capua angustiorana 221
