B. hylohii. If so they are a species new to liiitain, and in order to be 

 sure of this I have sent specimens for identification to \}v Szepligeti in 

 Budapest. 



Ratzeburg's description of the species is as follows : " B. hylobii. 

 1|-2J mm. Outer and inner discoidal cells equally long. Second 

 cubital cell a little larger than the first. Antennae of ? 31 jointed. 

 The ovipositor as long as the abdomen and tending to curve upwards. 

 Head approximately as broad as the thorax. All the legs and the 

 greater part of the first half of the abdomen reddish brown. In the 

 $ only the middle of the first segment is black. In the male the first

ring may be almost quite black and. the last or posterior half of the 

 abdomen in both sexes is quite black. The thorax and head black 

 except in certain females when part of it is brownish." 



Ratzeburg expresses doubt as to making it a species, but he considers 

 that the shape and size of the discoidal cells entitle it to that distinction 

 from its near neighbours B. immutator and B. spathiformis. 



Messrs Elliott and Morley in their Hyraenopterous parasites of the 

 Colioptera refer to Ratzeburg's species but do not quote his description. 

 These references are the only two I have been able to obtain on the 

 subject^.
