Holotype $. England : Berkshire, Thatcham Reeds, near Newbury, 29.viii.1964, 

 swept from plants of Artemisia vulgaris L. {Graham), in Hope Department, University 

 Museum, Oxford. 



Paratypes. Same locality and host-plant as holotype, 5 $, 29.viii.1964, 2 $, 

 31.viii.1964 [Graham], in Graham collection. 



Biology. Unknown. 



Habrocytus tibiellus (Zetterstedt) comb. n. 



Pteromalus tibiellus Zetterstedt, 1838 : 425, $. 



Type material. One female, LECTOTYPE, labelled in Zetterstedt's handwriting 

 " Pt. tibiellus $ Joh. Ro." The specimen was partly covered with mould but I 

 have managed to determine its characters fairly well. The male is unknown. 



Britain, Sweden. England [new record] : Oxford, 1 $, 27. ix. 1954 (Graham) ; 

 this appears to be identical with the lectotype of tibiellus. 

 Biology. Unknown. 



Habrocytus scandiae sp. n. 



(Text-fig. 399) 



$. Head and thorax mainly dark green ; occipital surface of head, pronotal neck, meso- 

 pleuron mainly, mesoscutum sometimes partly, bluish black ; basal tergite of gaster green, 

 the rest of the gaster varied with greenish and bronze, the disc bronze or purplish. Antennal 

 scape blackish with a metallic tinge, testaceous basally ; pedicellus blackish, paler apically ; 

 fiagellum brown, slightly paler beneath. Coxae, and femora except their tips rather narrowly, 

 concolorous with the thorax ; trochanters mainly dark ; tibiae fuscous except at base and 

 apex ; remaining parts of legs testaceous, with tips of tarsi fuscous. Tegulae black with a 

 metallic gloss. Wings hyaline ; venation fulvous to testaceous, parastigma and stigma some- 

 times slightly darker. Length 1-7 to 2 mm. 



Head about 1-2 times as broad as mesoscutum, in dorsal view about 2-2 times as broad as 

 long ; temples hardly more than one quarter as long as eyes, converging strongly and curved ; 

 POL 1-5 to i-6 OOL. Head in frontal view suboval ; eyes separated by 1-5 to 1-55 times 

 their length. Malar space from barely half to slightly more than half, the length of an eye. 

 Clypeus finely strigose, its anterior margin shallowly emarginate and with a slight impression in 

 the middle, the striae extending only slightly on to the genae and face. Head finely reticulate, 

 the frons rather more coarsely. Antennae (Text-fig. 399) with scape slightly more than three 

 quarters the length of an eye, but reaching only to the level of the lower edge of the median 

 ocellus ; combined length of pedicellus and fiagellum much less than breadth of head ; pedi- 

 cellus (profile) about i-6 times as long as broad, distinctly longer than the first funicular seg- 

 ment ; fiagellum proximally not stouter than the pedicellus, but thickening distad so as to be 

 rather strongly clavate ; first and second funicular segments quadrate or slightly longer than 

 broad, the following subquadrate, or the sixth, and sometimes the fifth, very slightly transverse ; 

 clava about twice as long as broad, its length equalling two and a half to two and three quarters 

 of the preceding funicular segments ; sensilla not very numerous, in one row on each funicular 

 segment. 



Thorax about 1-5 times as long as broad. Pronotal collar slightly less wide than the meso- 

 scutum, about as long medially as at the sides, from slightly less than to about one fifth as long
