INSECTS 



county in the early autumn. Plusia chrysith and P. iota are generally distributed and in some 

 seasons frequent. P. orichalcea was recorded from Cornwall in the Entomologist''! Annual for 1871; 

 it has recently been taken at Mount Edgcumbe. P. festucae has been recorded from Whitsand 

 Bay, Falmouth, and Penzance. P. pulchrina was taken by Reading at Saltash and by Baily at Paul. 

 In 1 904 it was found near Liskeard and at Altarnun. P. gamma is everywhere plentiful from May 

 to September. An example of P. ni was taken by Miss Carne in her garden at Penzance in May, 

 1869 (E. M. M., iii, 1 88). One of P. interrogationis was captured in the woods at Trerice near 

 Newquay in July, 1902. P. tripartita and P. triplasia are generally distributed on the mainland 

 and at Scilly ; the former is in some districts common. A fine specimen of Catocala nupta was taken 

 at sugar near Looe by Marryat in 1890. Euclidia mi and E. glyphica are locally distributed along 

 the southern half of the county ; the former is somewhat scarce, the latter in some seasons 

 plentiful. Erastria fasciana is widespread but local, and nowhere common. Eustrotia venustula 

 has been reported from Mousehole, but evidently in error. E. luctuosa has been taken on clover 

 lately at Looe. E. uncula was not uncommon at Falmouth fifty years ago, but has apparently died 

 out ; Marquand recorded it from Penzance. E. viridaria is commoner on the heaths and moor- 

 lands of the east than of the west. Panemeria tenebrata is not infrequently taken in South-east 

 Cornwall and occasionally as far west as Falmouth. Rivula sericea/is is very local, but not 

 uncommon along the south. 



OCNERIADAE 



Orgyia gonostigma has been taken singly from time to time in the southern half of the county, 

 but is very scarce. The larvae of 0. antiqua do occasional damage locally in Cornish gardens and 

 orchards by devouring the foliage of the trees and shrubs. Apple trees have been attacked at 

 Launceston and St. Columb, roses and laburnum at Bodmin, and a pear tree at Liskeard, but so far 

 the mischief done has been small compared with its ravages in some counties. Dasychira pudibunda 

 is common in woods and copses throughout the county, but has not been recorded from Scilly. 

 The larvae are at times abundant on the young shoots of the elm. Co/ocasia coryli has been taken 

 at Launceston, North Hill, Camelford, Liskeard, and Restormel. Porthesia similis has been 

 taken in the Land's End district and occasionally at Scilly. Euproctis chrysorrhoea was obtained 

 in the west by A. H. Jenkin. Stilpnotia salicis was obtained by Marryat near Looe in 1890, and 

 has been taken lately near Calstock. Ocneria monacha has been frequently captured in East and 

 Middle Cornwall but does not seem to have been recorded west of Truro. 0. dispar was taken 

 by Marshall at Botus Fleming. 



NOTODONTINA 



HYDRIOMENIDAE 



Trichopteryx viretata has been reported from Bodmin and from near Helston, and was taken 

 in 1902 at Launceston and Lostwithiel, and last year at Newquay and Millook. T. carpinata was 

 first recorded by A. H. Jenkin, but has been subsequently obtained near Calstock, at Trebartha, 

 and near St. Columb. Mysticoptera sexalisata was obtained in 1905 close to Liskeard. Lobophora 

 halterata has been recorded from East Cornwall by Marshall, and was twice taken last year on the 

 banks of the Lynher and once near North Hill. Chloroclystis coronata occurs very sparingly near 

 Lostwithiel and has been obtained near Cargreen, at Liskeard, in the Penzance district, and by 

 Adkin at Scilly. C. rectangulata is common in orchards throughout the county, and in some 

 seasons, notably in 1900, the larvae do considerable mischief by feeding on the flower buds and 

 newly formed fruit. In 1905 it practically destroyed the apple crop in one or two gardens around 

 Bodmin, and specimens were sent in for identification and advice from Truro and from Penryn. 

 C. debiliata is scarce and local, but has been obtained at Altarnun, Liskeard, Truro, and Newquay. 

 Gymnosce/is pumilata is widely distributed, and in places not uncommon, especially in West Cornwall 

 and at Scilly. Tephroclystis venosata is scarce, but has been found at Mount Edgcumbe, Callington, 

 Bodmin, and Falmouth, and has been bred from the pods of Silene maritima from Padstow. 

 T. expallidiata was captured by Miss L. M. Saunders at the flowers of golden-rod near Bishop's Wood, 

 Truro. T. campanulata was taken several times by Marshall in East Cornwall. T. minutata was 

 captured in 1901 on heather near St. Cleer, and in 1902 at Cardinham. T. absinthiata is wide- 

 spread but local ; it has been taken lately on the middle Lynher, at Looe and at Fowey, is not 

 uncommon some seasons at Scilly, and was recorded by Cocks from Falmouth and by Marquand 

 from Penzance. T. assimilata occurs at times among currant bushes at Liskeard and Bodmin, and 

 has been taken once at Newquay. T. va/erianata was bred from larvae on the fruits of valerian 

 at Bodmin in 1902, and two were captured at Millook in* 1904. T. albipunctata has been taken 

 at Angelica near St. Germans and at Looe. T. vulgata is mentioned by Atmore as common about 

 Penzance. T. oblongata is local, but not uncommon, especially at Padstow, Helston, and Scilly %
