TWO UNEECORDED BRITISH HYMENOPTERA -. HEDYCHRUM 

 RUTILAN8, Daulbom, AND (?) SALIUS FROPINQUUS, Lkp. 



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



In looking the other day through some Hymcnopfera collected at 

 Lyndhurst by Misss Ethel Ohawner, I was pleased but not surprised 

 to recognise a specimen ( $ ) of a Chrysid, which I have long thought 

 must occur in this country. This is the true Hcdijcliriim ratilans, 

 Uahlb. (not to be confounded with the insect so identified by F. 

 Smith and Marshall, which is a Holopyga). It is widely distributed 

 throughout Europe, not uncommon in the north of France, and J 

 have a specimen taken by Mr. E. Saunders this year in Jersey. Its 

 appearance here is therefore quite natural. 



Miss Chawner says, " 1 took it on a piece of rustic woodwork 

 close to a dry and sandy ditch in this garden. The time was either 

 July or August (I think the latter) of 1899." 



Heddjcliriim rutilans is easily distinguished from our other Hedy- 

 chrum (viz., nohile, Scop., = luciduhim, F.) by its very different 

 colouring, which a good deal resembles that of the much smaller 

 Hedi/chridium minutwn, Lep. The vertex, and the whole front of the 

 thorax, up to and inclusive of the scutellum, are concolorous with 

 the abdomen, of a fiery tint (rather rosy-red than golden), which in 

 some lights appears " shot " with green. In the ^ this greenish tint 

 is stronger, and sometimes quite overpowers the red, but there is no 

 such striking difference between the coloration of the two sexes as 

 occurs in nohile. Structurally the two species are best distinguished 

 by the pronotum, which in rutllans is longer, and (as seen from above) 

 narrowing more distinctly fi-om base to apex. Also the hairing of 

 the head in rutilans is very short and pale, while in nobiJe it is pretty 

 long and distinctly blackish. 



In my Synoptic Table (Ent. Mt). Mag., 19U0, p. l?A)) rutilans 

 should follow nohile, ? , and be characterized — " vertex and scutellum 

 as well as pro- and mesonotum reddish-fiery." The description of 

 nohile, $ , should read, " vertex and scutellum greenish-blue, pro- and 

 mesonotum golden." 



The above w^as not my only interesting " find " among INIisa 

 Chawner's captures. They included also two specimens (both ? ) of 

 a Salius, of which at the time I could only say that it was quite un- 

 like anything known to me as British. But having since compared 

 them with my foreign Salii, I believe them to be identical with two
