turation, iieuratiou, relative leugth of pro- and mesothorax, and all 

 such characters as can be seen in the present condition of the insects 

 representing it, agree precisely with those of R. gloriosa, Fab. (The 

 claws of the tarsi in my own specimen are so disguised in dirt, that I 

 have found it impossible to examine them satisfactorily) Smith's 

 further identification of his fervidum with rutilans, Dhb., though 

 accepted by Marshall, is simply an additional error. True rutilans, 

 Dhb., of which I have many continental specimens, is a totally 

 different insect, and a genuine Hedyclirum (with sharp lateral spines 

 on the apical segment), while our species is an unmistakeable Holopyga. 

 It is unfortunate that none of the above three specimens bears any 

 ticket of locality. Still I am inclined to trust Shuckard's statement 

 about Mr. W. W. Saunders' captures, and to hope, therefore, that the 

 species is really British. For H. fervidum, then, we may substitute 

 in our list Holopyga gloriosn, Fab. 



Hedychruni roseum —Of this species I need only remark that it 

 belongs to the genus Redychridium, and should be called Hedychridium 

 roseum, Eossi. It cannot be confounded with anything else. 



Hedyclirum ardens. — Under this name two species have been mixed. 

 All the specimens in the Museum, and most of those in other collec- 

 tions, belong to Hedychridium minutum, Lep., which is identified by 

 Mocsary with ardens, Coq. This species, then (our common one) rndt-y 

 retain the name Hedychridium ardens, Coq. (= minutum, Lep., Dhb., 

 etc.). But, in Smith's collection, ardens includes two specimens of 

 Hedychridium integrum, Dhb., an insect not hitherto recorded as 

 British, but of which I possess three specimens taken at Chobham by 

 Mr. E. Saunders. It is not unlike ardens, though when once recognised 

 it is easily distinguishable, even by its coloration (which is somewhat 

 darker) and general appearance. It has, however, a much more finely 

 punctured thorax, and the abdomen is fringed with rather long hairs 

 towards the apex, where ardens has only a short pubescence. Good 

 figures of integrum and ardens (there called minutum) may be seen in 

 Dahlbom (Hym. Europ., plate iv). There is, as said above, no speci- 

 men of integrum in the Museum, and I suspect it is local, if not rare, 

 in England ; but I have taken it freely in Switzerland, and it seems to 

 occur all over the Continent. 



(jrenus Chrysis. 

 Of the first six species recorded by Smith in this genus, viz., 

 iqnita, Ruddii, fulgida, bidentata (= viriduln, Lin.), succincta, and 

 cyanea, little need be said here. All have been correctly determined
