PTEROMALIDAE OF N.W. EUROPE 535 



27.vii.1959, I swept a $ at Falsterbo, Skane, Sweden, which has the gaster only 

 about equal in length to the head plus thorax, but otherwise agrees with the 

 lectotype. 



Sweden. 



Biology. Unknown. 



Habrocytus aureolus Thomson 



? Pteromalus Ortalus Walker, 1839 : 241, $. 

 Habrocytus aureolus Thomson, 1878 : 125, $. 



Type material. Pteromalus ortalus Walker. Syntypes, 6 specimens. LECTO- 

 TYPE, the third specimen, bearing a Waterhouse label. I think it quite possible 

 that the lectotype is a male of aureolus Thomson but as I have seen no bred males 

 of the latter, I cannot be sure. 



Habrocytus aureolus Thomson. Syntypes, 2 $. LECTOTYPE labelled " Sm " 

 [Smaland] and " Bhn " [Boheman]. 



Britain, Sweden, Germany, Czechoslovakia ; rather rare. New to Britain : 

 Berkshire, Wytham Wood, 2 $, 8.vii.i956, 7.x. 1956 (Graham) ; Kent, Lewisham, 

 1 $, 29.V.1892 (A.J. Chitty). 



Biology. Reared in Germany, Neuenburg, June 1964, by Dr. H. Pschorn- 

 Walcher, from Lycaota xylostei (Giraud), a sawfly which forms galls on Lonicera 

 xylosteum L. Dr. Boucek showed me specimens from Czechoslovakia which he had 

 obtained from a host on Ligustrum. Imagines June-October (one record for May). 



The female of this beautiful species is easily recognized by the coppery or purplish 

 copper colour of the body, the margined pronotal collar, somewhat flattened thorax, 

 and the form of the propodeum. 



Species sola 

 Habrocytus helenomus sp. n. 



(Text-fig. 397) 



?. Head and thorax bronze, the front of the head greenish ; propodeum often olive or 

 bluish-tinged ; basal tergite of gaster partly green, rest of gaster bronze with some weak 

 greenish reflections. Antennal scape testaceous, usually more or less infuscate apically ; 

 pedicellus and flagellum fuscous. Coxae concolorous with thorax ; trochanters mainly test- 

 aceous ; femora fuscous, rather broadly pale apically ; rest of legs testaceous with tips of 

 tarsi brown ; mid and hind tibiae sometimes slightly brownish medially. Tegulae testaceous 

 to brown. Wings subhyaline ; venation testaceous with the parastigma and stigma slightly 

 darker. Length 2-3 to 2-9 mm. 



Head slightly broader than the mesoscutum, in dorsal view hardly more than twice as broad 

 as long ; temples slightly more than one third as long as eyes, converging moderately strongly 

 and rather straight ; POL 1-25 to 1-3 OOL. Head in frontal view transversely oval ; eyes 

 separated by 1 -3 to 1 -35 times their length. Malar space one third the length of an eye or 

 slightly more. Anterior margin of clypeus moderately deeply emarginate, with an impression 

 in the middle. Head finely reticulate ; clypeus strigose, the striae extending slightly on to the 

 face and genae. Antennae (Text-fig. 397) inserted distinctly above the level of the ventral
