INSECTS 



Truro gardens. Three specimens of L. luzella were captured by Atmore in Trevaylor Valley, 

 near Penzance. L, praelatella has been taken on strawberry beds at Penryn. The grubs of 

 L. rubiella caused considerable damage to the raspberry crop in some Penzance gardens in 1899, 

 and a number of them were found near Truro in 1905. Monopis ferruginella is fairly common in 

 dry outhouses and barns in the east of the county, and is reported from Scilly. M. rusticella occurs 

 occasionally in barns about Truro, and was found by Marshall at Botus Fleming. Trichophaga 

 tapetiella is widespread and often abundant in houses. Tinea arcella was taken near the Lion's Den, 

 Millook, in August, 1905. T. corticella has been obtained occasionally near the railway viaduct at 

 Truro. T. granella is very common in granaries and in stables, especially in the east. T. cloacella 

 is widespread, but local. T. nigripunctella has been taken about Bodmin. T. fuscipunctella occurs 

 all over the county, and is often abundant in stables, haylofts and dry outhouses. T. pellionella is 

 very common in houses. T. pallescentella has lately been taken on grain, chaff, crushed oats, &c., 

 at Truro and at Falmouth. T. lapella is common about Truro, and has been taken by Atmore at 

 Penzance. T. semifulvella frequents a hedgebank on the way from Truro to Carnon Downs. 

 Stainton says that a species allied to T. argentimaculella was taken by Jenkinson at Scilly. Nemo- 

 phora swammerdammella is common about Bishop's Wood, Truro. N. schwarziella is at times 

 most abundant in the east of the county, and small clouds of this species have been seen as far west 

 as Truro. N. metaxella has been recorded by Thomas from St. Germans. Adela fibulella was 

 common in the Restormel Valley in 1900. A. croesella has been taken several times in gardens at 

 Truro. A. degeerella is occasionally found in several of the woods near the Tamar. A. viridella 

 is common in the north-east of the county and about Liskeard, and was recorded by Marshall from 

 Botus Fleming. A. cuprella has been taken twice at willow catkins near Malpas, Truro. 



MICROPTERYGINA 

 HEPIALIDAE 



The gold swift Heplalus hectus is very local and scarce. It has been taken at Launceston, 

 Truro, Falmouth, Penzance and Mawgan-in-Pyder. H. lupulinus is in some seasons widespread 

 and common. H. sylvinus has been taken sparingly from St. Austell to Penzance. H. humuli is 

 often common in the east and middle of the county, but is less frequently seen in the west. 



MICROPTERYGIDAE 



Micropteryx sparmannella has been taken near Bodmin. M. purpurella is on the list from the 

 upper T.unar district. M. semipurpurella has been bred from the leaves of birch gathered at Luxulian, 

 and M. unimaculella from similar leaves collected in the Looe Valley. M. subpurpurella occurred 

 in abundance in Coomb Valley, Kilkhampton, in May, 1902, and has been bred from oak leaves 

 taken at Millook. Eriocephala thunbergella was common in Bishop's Wood, Truro, in May, 1901. 

 E. aruncella occurs at St. Clement's and in the woods at Tregothnan. E. calthella was taken by 

 Marshall in East Cornwall. 



DIPTERA 



Except for VerralPs recent volume on the Syrphidae and some of their allies the literature on 

 the Diptera is practically inaccessible to the ordinary worker. The species, too, in many cases are 

 so difficult to identify that records for this order are chiefly the result of expert investigation. In 

 1890 Mr. C. W. Dale published in the Transactions of the Penzance Natural History and Antiquarian 

 Society a list of about 340 species taken by himself and his father, Mr. J. C. Dale, in West 

 Cornwall. In vol. xl of the Entomologists 1 Monthly Magazine, Colonel Yerbury gives a list of 

 thirty-four species from Scilly. These, with the references to Cornwall in Verrall's work already 

 mentioned, and occasional notes in periodical literature, seem to exhaust the published records of 

 Cornish Flies. 



In the compilation of the accompanying list the writer has been particularly fortunate in his 

 friends. Mr. C. G. Lamb of Cambridge has not only supplied him with an annotated list of the 

 flies he has identified in the Padstow district, but he has sent a duplicate collection for the museum 

 at Truro ; Mr. A. J. Tate of Truro has been most generous in supplying local data and specimens, 

 and as far back as 1890 the late Rev. J. Winsor Aubrey, rector of Hale, Hants, drew up a 

 list of the named Diptera in his collection that had been taken at Looe. Valuable help was also 

 given by the late Rev. T. A. Marshall of Botus Fleming. In the following list the letters A., D., 

 L., M., T., V., and Y. stand for Aubrey, Dale, Lamb, Marshall, Tate, Verrall, and Yerbury 

 respectively. A few records by Mr. F. Jenkinson from Scilly are marked J.
