Biology. Reared in Sweden from Pogonocherus hispidus L. (Col., Lamiidae), see 

 Kerrich & Graham (1957 : 287). One female reared " from beetle burrow in apple 

 twig," England, Bedfordshire, Leighton Buzzard, v. 1906 (H. Donisthorpe).

Type material. For designation of lectotypes for Cleonymus cyanescens Forster 

 and Trigonoderus pedicellaris Thomson, see Kerrich & Graham (1957 : 285-286). 

 These two were synonymized by Novitzky (1955 : 27). 



Hetroxys gribodoi van Vollenhoven. Syntypes, 2 $, taken in the north of Italy 

 by J. Gribodo of Turin (location of types unknown, perhaps in Rijksmuseum van 

 Natuurlijke Historic Leiden). From Vollenhoven's description and his coloured 

 figure of the female, I have no doubt that gribodoi is the same as cyanescens (Forster).

Species incorrectly placed in Trigonoderus : 



Trigonoderus contractus Walker (1872 : 85, $) was listed by Kerrich & Graham 

 (1957 : 299) as a doubtful species because the type could not be located. I have 

 since found the type : a female labelled " Marshall coll. 1904-120 " ; "contractus 

 Walk " ; " In BM (1938) as Trigonoderus contractus ". It is a female of Calosota 

 acron (Walker) in Eupelmidae (syn. n.).

The European species were first revised by Kerrich & Graham (1957) and keys for 

 their identification were provided by Ferriere & Kerrich (1958). Three species were 

 recognized in these two papers ; a fourth has since been described by Hedqvist, and 

 is included here.
