have only taken J" ^, though I have ? ? from Dr. Capron's collection. 

 In Stephens's coll. at South Kensington there are three ? ? , and one 

 cJ (the latter is ticketed didi/mus ; but 1 have met with the real 

 didymm, K]., only in Switzerland and the Mediterranean regions, 

 and do not believe it is a British species). 



Serotinus, var. tarsatus (see Konow). — This is the form described 

 by King as Tentliredo serotina, and by subsequent authors (Hartig, 

 Thomson, Cameron) as Emphytus serotinus, Kl. 



Four other forms, evidently closely allied to serotinus, are de- 

 scribed by Klug ; but after long and careful consideration of these 

 descriptions, 1 feel driven to the conclusion that most of them cer- 

 tainly, and probably all of them, refer to mere individual aberrations 

 of serotinus, and not even to distinct races of it, much less to distinct 

 species.

SOME REMARKS ON THE EUPLECTUS KUNZEI, Aube, OF 

 BRITISH COLLECTIONS. 



BY G. C. CHAMPION, F.Z.S. 



The recent record of two additional British Euplecti has induced 

 me to re-examine certain species in my own collection. The two 

 large forms only, viz., the insects doing duty for E. hunzei and E. 

 duponti, Aube, require special comment. The first-mentioned of 

 these, E. hunzei (represented by various specimens), proves to be E. 

 auheanus, Reitt., and the other (a ^ from Cobham Park, Kent, found 

 by Commander Walker on July 30th, 1S73) is E. brunneus, Grimmer 

 (= E. hunzei, Aube). This latter was introduced as British in 1862 

 by G. R. Waterhouse [Trans. Eut. Soc. Lond. (3), i, pp. 45, 46] upon 

 two examples, presumably ? $ , from Darenth Wood and Greenhithe 

 respectively ; he, however, observed at the same time that the com- 

 paratively large size of the head was not mentioned by Aube. The 

 (J of this insect was described by Blateh in 1886 (Ent. Mo. Mag., 

 xxii, p. 203), from a specimen from Darenth Wood, in the Power col- 

 lection, but he could not have seen Reitter's definition of that sex of 

 E. brunneus (hunzei) — ^: Metasternum lougitudinaliter sulcatum, &c. 

 [Ins. Deutchl., Ill, 2, p. 119 (1882)], — the metasternal character at 

 once separating the ^ of E. brunneus {hunzei) from that of E. 

 aubeanus, in which the sulcus is barely traceable. E. aubeanus, 

 Eeitt., was described in 1881 from two females from Mecklenburg
