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
