Ocyptera. 123 



Distinct postocellar and occipital bristles. Behind postocular bristles 

 no black hairs or only a few above. Frontal bristles only reaching 

 to the insertion of antennæ, in male all crossing, in female the upper- 

 most directed forwards or more or less outwards. Cheeks bare. Vibrissæ 

 not ascending. Epistoma almost not retreating, with a low keel in 

 the middle above, reflected and somewliat prominent below. Pro- 

 boscis and oral cone rather long, of about eqiial length, the proboscis 

 slender with small labella. Clypeus linear, only a little incised at 

 apex. Palpi quite small and rudimentary. Antennæ inserted at about 

 the middle of the eye, somewhat short, third joint from about 

 as long to twice as long as second; arista bare with second joint 

 a little or almost not elongated. Thorax rectangular; the transverse 

 suture at or behind the middle. Three postsutural dorsocentrals, no 

 acrostichals; a posthumeral and two intraalar bristles. Scutellum 

 with one, two or three marginal bristles on each side as either the 

 basal or both basal and apical may be wanting. Two sternopleural 

 bristles. Pteropleura covered with short hairs, but without any bristle 

 or bundle of longer hairs. Abdomen long, cylindrical or somewhat 

 narrowing towards base; excavation at base small; either discai 

 and marginal or only marginal bristles present; second segment 

 with bristles. Male genitalia forming a rounded knob at apex; fifth 

 sternite small. Female abdomen ending with a thick or more slender 

 ovipositor, curved in under venter, the last segment ending with 

 two points or two larger claws. In some species there is in the female 

 at the apical corners of second segment on ventral side a patch of 

 strong short spinules and a similar, but of less strong spinules, on 

 third segment. Legs long, with rather long bristles on ventral side 

 of femora and on tibiæ, but in female the femora nearly bare below, 

 only hind femora with a bristle in the middle; the ventral bristle 

 on middle tibiæ present in both sexes. Claws and pulvilli strongly 

 elongate in male. In female the three last joints on front tarsi dilated. 

 Wings with first posterior cell closed and petiolate, the peduncle 

 curved upwards, ending considerably before apex of wing; discai 

 angle rectangular, without or with a short veinlet. No costal spine. 



The species are parasitic on imagines of Rhynchota^ but the 

 biology is known only for two species, the Danish brassicaria on Doly- 

 coris baccarum^ and the non Danish bicolor on Rhaphigaster nebulosa, 

 likewise non Danish. The species belong probably to Pantel's group 9. 



Of the genus about 20 European species are known; 3 occur in 

 Denmark.
