CHRYSIDIDAE HYMENOPTERA TUBULIFERA Ruby-Wasps Though these beautiful flies with their brilliant metallic colours are by no means rare, they do not seem to have been collected by any entomologist in the county. This may be due to their occupying a sort of ' no man's land ' between the Aculeata and the Ichneumons, and partly because there has been till lately no easily accessible account of the British species. The females lay their eggs singly in the cells of a particular bee or wasp just after the latter has stored the nutriment required for her own offspring, and deposited her own egg in the space prepared. The Chrysid larva matures at the expense of the rightful owner, which is invariably destroyed. Out of the twenty-five species recognized for the British Isles, nine have been obtained in the county up to the present. Hedychridium minutum has been obtained at Whitsand Bay, Gerran's Bay, Maenporth and Newquay, and two were taken on St. Martin's, Scilly, in July, 1903. H. roseumhas twice been found at Looe and once at Perranporth. Chrysis neglecta was obtained by Thomas near Lostwithiel, and has been sent in from Penzance. C. viridula has been recorded by Bignell from Rame, and has been taken several times at Whitsand Bay. Specimens were received last year from Gerran's Bay and from Newquay. C. cyanea occurred about Malpas in 1903, and single examples have been obtained from Falmouth, St. Ives and Bude. C. sucdncta is represented in the Schools' collection by one specimen from St. Ives and two from the Looe valley. C. ruddii was taken by Bignell at Millook, and has been captured at Newquay and reported from Looe. C.pustulosa was also recorded by Bignell from Millook, and was not uncommon there in July, 1905. C. ignita is usually common, and appears to be generally distributed. This beautiful ' Firetail fly ' was plentiful along the Leets at Truro in 1900 and 1901, and several small groups were at times observed clustering round the opening of the burrows made by an Odynerus in the mortar of a stone wall on the far side of the water. ACULEATA Wasps, Bees, Ants, etc. The ants, wasps, and bees of West Cornwall received considerable attention from Mr. E. D. Marquand, who published a descriptive account of Land's End Aculeata in the Transactions of the Penzance Natural History and Antiquarian Society (new ser.) vol. i, and a supplement in vol. iii. Mr. G. A. J. Rothney has made several visits to the north coast of Cornwall, and recorded his cap- tures in the Entomologist's Monthly Magazine, vols. xxiv xxxiv. In vol. xxxviii, Mr. E. B. Nevinson published a list of Aculeata Hymenoptera taken at Newquay. Various other visiting entomologists have collected them from time to time, and the more important of the older records are mentioned in Saunders's British Hymenoptera Aculeata. For the last five years Mr. Edwin C. H. Davies, of St. Issey, has assiduously collected these somewhat neglected insects throughout his district, and as all his captures have been identified by Saunders, the annotated list he has kindly sent the writer is 181
