B. sericevs Herlist. — There is no reason to suppose that this 

 insect is. or ever was, British. The single specimen of ophihalmicus 

 in the Stephensian collection (which, although not labelled as the type, 

 may be assumed in default of any other example to represent his 

 ophfhalmlcvs) certainly belongs to the same species as those in the 

 Power and other Biitish collections under this name. It has no re- 

 semblance to what is understood on the Continent as R. sericens 

 Herbst, which is placed by modern authors in a different sub-genus, 

 the elytra appearing confusedly punctured, by reason of the large 

 punctures in the interstices. Walton (Ann. Nat. Hist. XIII, 1844, 

 p. 84) says: "I have not observed the B. sericens of Herbst in any 

 British Collection." As to whether B. ophthalmicus is identical with 

 B. oJivacens Gyll., the only specimen under this name in the General 

 Collection at the British Museum is too mutilated to enable me to 

 form an opinion. The name olivaceus Gryll. has priority. 



B. aeneoinrens ab. fragariae Gryll. — I have a specimen from Clay- 

 gate of a dark blue colour, without any greenish hue. 



B. tomentosvs Gyll. and harivoodi Joy. — I have always taken these 

 two forms together, at Loughton, Farnham, Claygate and Wimbledon ; 

 at the last named place they occurred on many occasions.

A NEW SPECIES OF CERAPTER0CEEU8 WESTAV. {EUSEMION 

 DAHLB.J (ENCYETIDAE: CHALCIDOIDEA) FEOM ITALY. 

 BY DR. LUIGI MAST 

 (Museo civico di storia naturale in Geneva). 

 In Boll. Lab. Portici, 1909, Vol. IV, p. 6, tigs. 5-9, 1 have described 

 and figured under the name Cerapterocerus corniger (Wlk.), a species 

 which proves now to be distinct from that described by the English 

 author. I had judged the figure of the antenna of Eusemion corni- 

 gerum given by Walker (Notes on Chalcid., Pt. v., p, 73, 1872) to be 

 inexact, but after examining a specimen of cornigerum from Cam- 

 berley, Surrey (E. E. Green), it is evident that I have been mistaken 

 in this respect. U. cornigerum differs in several of its characters from 

 the Italian species. The latter may be referred to as E. italicuvx^ Masi. 

 In it the funicle is broader, the club nearly as long as wide, the fore- 

 wings are hyaline at the base, and the clear spot near the stigma is 

 prolonged into a narrow transverse band. Eusemion italicum has been 

 bred from the Coccid Ceroplastes rvsci collected at Catanzaro and 

 Portici.
