insect suhcyaneus (Ent. Mag., v, 519). It appears in Marshall's Cata- 

 logue as Epyris suhcyanea, Hal. When I first captured suhcyanea 

 here, using Ashmead's tables, I placed it in his genus Isobrctchium, 

 and only moved it into Epyris on discovering Haliday's figure 

 (Ent. Mag., iv, pi. xvi, £. 6), which is unmistakeable. I now find 

 that the Abbe Kieffer has moved suhcyanea into his genus Pseudiso- 

 hrachiim, to which I think it undoubtedly belongs, but I think it 

 is too large to be the ^ of P. cantianum. P. cantianum differs 

 from P. pubescens, Kieff., by having the disc of the thorax smooth, 

 and the 4th joint of the antenna? transverse, and from P. concolor, 

 Kieff., which is described as "glabre," by being more or less hairy. 

 P. intermedium, Kieff., the only other European species of which the 

 $ is known, is larger and has a black head. 



I expect to find that Pseudisohrachium suhcyaneum is parasitic 

 upon, or associates with, Myrmecina latreillei, but this is a mere 

 surmise.

ADDITIONS AND CORRECTIONS TO THE LIST OF 

 BRITISH HYMENOPTERA SINCE 1896. 



BY EDWARD SAUNDERS, F.R.S. 



It is now just 10 years since the completion of "The Hymenoptera 

 Aculeata of the British Islands," and numerous additional species have 

 been found in these Islands during the interval ; most of these have 

 been introduced through the pages of this Magazine, but I thought it 

 would probably be a convenience to British Hymenopterists to have 

 these scattered records arranged consecutively and also to have in- 

 corporated with them, such changes in synonyms, additions and 

 corrections as are required to bring the subject up to date. Many 

 important papers have been published on the Continent during the 

 last ten years, which have thrown much light on many of the formerly 

 obscure species, and have also indicated changes in synonyms which it 

 will be well to adopt so as to bring our nomenclature as much as 

 possible into concord with that of Continental Entomologists. I am 

 always averse to changing names which are in common use, but in 

 cases where we differ from practically all the Continental authorities, 

 I think we are bound to give up our names and adopt theirs, unless, 

 of course, we can prove that we have priority to support our views.
