3oo M. W. R. de V. GRAHAM 



of Angelica sylvestris L. (Graham), in Hope Department, University Museum, 

 Oxford. 



Paratypes. Same data as holotype, 2 <$, 2 $ ; same locality, 4.x. 1957, 2 ^, 4 $ and 

 1 gynandromorph, beaten from foliage of oak trees (Quercus robur L.) (Graham), in 

 Graham collection. 



The gynandromorphic specimen just mentioned is interesting as this condition 

 appears to be rare in Chalcidoidea ; the specimen is female except for its antennae, 

 which are those of a normal male. 



Biology. Unknown. 



Species sola 

 Gastrancistrus vernalis sp. n. 



(Text-figs. 204, 207, 229) 



$. Head and thorax green to blue ; gaster bronze, its dorsal surface, except as a rule the 

 disc, with greenish or bluish reflections which are most conspicuous on the basal tergite. Anten- 

 nae brownish testaceous ; scape dorsally, or mainly, infuscate ; pedicellus infuscate over its 

 proximal half or more ; incisures between the flagellar segments often brown, sometimes the 

 flagellum infuscate dorsally. Coxae concolorous with the thorax ; trochanters partly dark ; 

 femora blackish, except their tips which, like the tibiae and tarsi, are yellowish testaceous ; 

 tips of tarsi fuscous. Tegulae testaceous anteriorly, fuscous posteriorly. Wings slightly 

 infumate or subhyaline ; venation testaceous, the parastigma and stigmal vein often darker. 

 Length 2 to 2-4 mm. 



Head about 1 -2 times as broad as the mesoscutum, in dorsal view 1 -85 to 2 times as broad as 

 long ; temples one fifth to more than one quarter the length of the eyes, rounded off ; POL 

 about twice OOL, ocelli in a triangle whose base is about twice its height. Eyes rather large, 

 separated by hardly 1-2 times their own length. Head in front view a nearly regular oval, 

 about 1-25 times as broad as high ; both the vertex and the cheeks with a curved outline. 

 Malar space slightly less than half the length of an eye. Breadth of oral fossa about twice the 

 malar space. Clypeus only 1-5 to i-8 times as broad as long, alutaceous, its anterior margin 

 strongly and evenly curved. Mandibles rather small, their lower margin nearly straight ; the 

 outer (lower) tooth moderately long, the others decreasing gradually in length. The head, 

 apart from the smooth scrobes, has slightly, though distinctly, raised reticulation ; on the 

 vertex the reticulation is extremely fine, elsewhere it is rather less fine. Antenna (Text-fig. 229) 

 with scape approximately equal in length to the transverse diameter of an eye, about four times 

 as long as broad, not reaching the median ocellus ; combined length of pedicellus and flagellum 

 nearly equal to the breadth of the head ; pedicellus in profile about twice as long as broad, 

 distinctly longer than the first funicular segment ; flagellum of characteristic appearance because 

 of the hairs which clothe it being very short ; funicle proximally hardly stouter than the 

 pedicellus, thickening slightly distad, its first segment 1 -2 to 1 -4 times as long as broad, the 

 following segments subquadrate, or the distal segment very slightly transverse ; clava very 

 slightly broader than the fifth funicular segment, unusually long, about three times as long as 

 broad, nearly or quite as long as the four preceding funicular segments together. 



Thorax (Text-fig. 204) unusually elongate, 1-9 to 2-4 times as long as broad. Mesoscutum 

 only about 1 -4 times as broad as long, only slightly shiny, with rather strong reticulation which 

 is distinctly raised above the general surface ; this sculpture is extremely fine except in the 

 front portion of the mid lobe ; the scattered hairs which clothe the mesoscutum are unusually 

 short and arise from minute pits which are inconspicuous amid the reticulation ; notauli 

 relatively shallow. Scutellum hardly longer than the mesoscutum, much longer than broad,
