that Billberg's book is no more than what it professes to be, viz. : 

 " Enumeratio Insectorum in Museo Gust. Joh. Billberg," and we have 

 been unable to discover a single genus which can be accepted as valid, 

 all the species are obviously invalid when signed "Eg.," and the re- 

 mainder are open to doubt. We cannot accept Billberg's Enumeratio 

 as coming within the requirements of our code of rules — and empha- 

 sise Hummel's regret that any copy of it escaped the fire of 1822.

ELLAMPUS TRUNCATUS, Dahlb., CONFIRMED AS BRITISH. 

 BY THE REV. F. D. MORICE, M.A , F.E.S. 



In Ent. Mo. Mag., 1900, p. 107, T mentioned the existence of a 

 specimen of Ellampus truncatus, Dhlb., in Walcott's collection, now 

 the property of the Cambridge University Museum. I could then 

 say only that I " hoped " it might safely be treated as an addition to 

 the British list, but I have now definite evidence that E. truncatus is 

 really a British insect. 



Mr. A. II. Hamm, of Oxford, has sent to me for identification 

 what is undoubtedly a specimen of the same insect. It was taken by 

 Mr. W. Barnes on June 30th, 1901, in a garden at Southern Hill, 

 Beading. The captor said that it appeared to be running in and out 

 of holes in a rose tree trained against the wall of a house, and that 

 he met at the same time with specimens of Trypoxylon jigulus, Linn., 

 and clavicerum, Lep., Ellampus auratus, Linn., and Chrysis cyanea, 

 Linn. It seems very likely that one of the above two Fossors was 

 the "host," or rather " victim," of the E. truncatus, and perhaps also 

 of the auratus, which latter, I believe, infests several species of pith- 

 burrowing Fossors. (C cyanea is also said by M. du Buysson to be 

 attached to various species of Trypoxylon and Cemonus, and I have 

 generally found it about old gate posts inhabited by Trypoxylon, 

 CheJostoma, Osmia, &c, but on one occasion lately I was surprised to 

 meet with it, along with C. neglecta and C. viridula, haunting the 

 sandy burrows of Odynerus spinipes). 



I have already {I.e.) given the characters by which E. truncatus 

 may be distinguished from our other British Chrysids ; and will 

 therefore only add that the present specimen has been placed in the 

 collection of the Oxford University Museum (Hope Department), 

 and that I am indebted to Mr. Hamm for the details given above 

 respecting its capture.
