distinct species by Delucchi (1956a : 233) but Boucek (1965c : 23) considered 

 Thomson's type to be a dwarf of splendidus. Although slight differences are 

 discernible between the types of acutangulus and splendidus, I am disposed to 

 accept Boucek's view. 



The colour of the body in splendidus varies considerably from bright green (some 

 English females) through bright blue, to violet. A violet tinge seems more common 

 in Swedish specimens and in those from Central and Southern Europe ; I have 

 not seen it in British specimens. The length of the body in females varies from 

 2-6 to 5-5 mm. (rarely more).

 Moldavian S.S.R. ; North Africa. 



Biology. A male of splendidus was reared in southern England from a group of 

 galls produced by Tetramesa brevicornis (Walker) in stems of Festuca rubra L. var. 

 arenaria (Osb.) Fr., by Dr. Claridge (1958 : 227). In Britain imagines appear in 

 June and July ; in North Africa they have been taken in March and April.
