 INSECTS occur at intervals along the south coast. P. macularia is at times plentiful in the east, but is scarce elsewhere. P. obscuraria is widely spread but local. P. petraria is in some seasons not uncommon in the east, but apparently always scarce in the west. Crocota strigillaria has twice been taken near Saltash and once at Looe. C. gilvaria was captured at Bude in August, 1905. C. ochrearia has been obtained near Boscastle, at Whitsand Bay East, at Bodmin, and at Penzance. Theria ruplca- praria is not infrequently taken in overgrown hedgebanks in the east and middle of the county, but is evidently rare in the west. Hybernia leucophearia occurs about Kilkhampton, Poundstock, Laun- ceston, and Liskeard,and has been taken at Penzance by Marquand. H. marginaria is fairly common and generally distributed in the early spring. Three specimens of H. aurantiarla were captured by the Gannel several miles above Newquay in October, 1900. H. defoliaria is generally very scarce, but in 1899 the larvae attacked a number of gooseberry trees, black currants, and raspberry canes at Ludgvan, and so completely destroyed the leaves that they looked as if they had been scorched by fire. The same year larvae were sent in from Hayle and Camborne. Apocheima pedarta is widely spread but scarce. Biston hirtarius has been taken near Kilk- hampton, and was recorded by Cocks from Falmouth and by Marquand from Penzance. B. stratarius is occasionally found between the Bodmin Moors and the Tamar, and has been taken at Bodmin and at Penzance. B. betularius is generally distributed among the woods of the county. Deilinia pusaria is widespread but local, somewhat scarce in the north and at Scilly. D. exanthemata is generally distributed but scarce. At Scilly it has been captured several times. Ourapteryx sambucaria occurs everywhere, and is locally plentiful. Metrocampa prosapiaria is common in the eastern pinewoods but rare in the west. M. margarltaria is of frequent occurrence throughout the county. M. pulveraria has been captured at Saltash, Looe, and Bodmin. M. dolobraria occurs sparingly near Altarnun and Trebartha, and has been recorded from Bodmin and West Cornwall. Euchlaena prunaria has been taken between Launceston and Altarnun, at Calstock, Looe, and Bodmin. E. apiciaria is widely spread, but local and usually rather scarce. Selenia bilunaria is generally plentiful in March and April, and again in July. It has been obtained by Jenkinson at Scilly. S. lunaria has been taken at Bude, Launceston, Looe, Malpas, Falmouth and Penzance. S. tetralunaria occurs sparingly near Altarnun and at Launceston, in the middle reaches of the Lynher, and at Looe. Hygrochroa syringaria is of frequent occurrence in the east, but is very rarely recorded west of Liskeard. Co/otais pennarla was recorded by Marshall from East Cornwall and by Marquand and Baily from Penzance. It has been taken during the past five years at Bude, Callington, Saltash, Liskeard and Falmouth. Ennomos erosana was locally plentiful in 1901 between the Bodmin Moors and the Tamar ; it has not been recorded west of Liskeard. E. fuscantaria occurs among the oaks in Coomb valley, Kilkhampton, at Millook, and sparingly in the south-east of the county. Five specimens of E. alniaria were captured near Altarnun in August, 1901. E. quercinaria is occasionally taken in the east, and has been obtained by Marquand and by Baily in the Penzance district. E. autumnaria was recorded from East Cornwall by Marshall. Gonodontis bidentata has been taken sparingly along the south. G. elinguaria is widely spread but rarely common ; it has been twice obtained at Scilly. POLYPLOCIDAE Habrosyne derasa is of frequent occurrence in the east and south-east, but scarce elsewhere, though it has been found as far west as Penzance. Tbyatira bails is taken occasionally at sugar about Launceston, Liskeard, and Truro, and has been recorded from Calstock, Looe, and Penzance. Palimpsestls duplaris occurs sparingly in the larger woods of the east of the county, and at Liskeard and Doublebois. Polyploca diluta is evidently confined to the north-east of the county, where it has been occasionally taken about Kilkhampton, Bude, Millook and Launceston. A single example of P.favicornis was taken near St. Germans in March, 1905. P. ridens is recorded by Marshall from the east, and has been taken lately near Altarnun. It is said to have been common once about Camborne. SPHINGIDAE Hemaris bombyliformis has been taken near Bude, at Saltash, at Budock Bottoms by Cocks, and at Penzance by Marquand. H. fuctformis is very scarce, but has been captured at Looe, Falmouth, and Penzance. Macroglossa ste/tatarum, the humming-bird moth, is generally distributed and common all over the mainland and at Scilly. Deilephila porcellus y though widely spread, is apparently nowhere common. It occurs near Altarnun and in the Plymouth district ; and single specimens have been taken all along the south, and at Newquay, Padstow, and Bude. D. elpenor is commoner and more generally distributed. Formerly it was not uncommon at Enys, where the larvae fed upon buckbean (J. D. Enys). D. celerio was taken by E. P. Marquand in the Penzance district. An example of D. nerii in splendid condition was taken at a white phlox in the garden at Miramar, Tregoll's Road, Truro, early in October, 1901, and is now in the museum of the Royal Institution 215
