76 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Hymenoptera. 



both species the temples and cheeks are margined ; there is a distinct mahir space. 

 Temples broad, rounded ; the occiput broadly, roundly incised, not transverse. 



This is the only genus of Ichneumoninae (the group to which AucUandella 

 belongs) with abbreviated wings, although apterous and semiapterous species are 

 common enough with the Cri/plinae. It differs further from typical Ichneumoninae 

 in the metanotum being entirely without longitudinal or transverse keels. The 

 long, projecting ovipositor also is characteristic ; but this is not altogether peculiar, 

 as Exefhanes has a similar one, as well as 8 distinct abdominal segments In both 

 the Auckland Island species the base of the tibiae is narrowed. The calcaria 

 are short, the claws simple. 



Aucklandella flavomaculata, sp. n. (Plate III, fig. 7.) 



Rufo-ferruginous ; the inner eye-orbits, the line continued more broadly to the 

 occiput, a spot on the top of the outer and a larger one on the bottom extending 

 on to the malar space, a broad line on the edge of the pronotum, tegulae, a line on 

 either side of the mesonotum, a small spot on the base of the mesopleurae above 

 and one on the apex lower down, and the apex of the 4 anterior trochanters, sulphur- 

 yellow. Wings hyaline, the costa blackish, the basal nervures testaceous, the apical 

 much paler, the stigma pale yellow. Female. 



Length, 9 ram. ; ovipositor, 1 mm. 



Front and vertex moderately closely and finely punctured, and covered with 

 short white pubescence ; the face and clypeus much more strongly punctured ; the 

 2 are clearly separated by a furrow, which ends laterally in a large transverse fovea ; 

 they are roundly convex. Base of mandibles tinged with yellow ; the teeth black. 

 Metanotum finely punctured, the scutellum more weakly so to shortly beyond the 

 middle. Metanotum finely closely shagreened ; its apical slope in the centre irregu- 

 larly longitudinally striated, almost reticulated, this part being bordered by keels ; 

 the part outside it is more strongly shagreened than the base. Basal segment of 

 abdomen finely shagreened ; the base of the 2nd iS; at the sides, slightly transversely 

 depressed. 



Aucklandella nigromaculata, sp. nov. 



Dark rufo-testaceous ; the temples broadly, base and apex of metanotum and 

 a line down the centre uniting the black basal and apical parts, the central de- 

 pressed part of propleurae, the mesopleurae broadly above, the greater part of the 

 metapleurae and of the back of the abdomen, black ; a line on the inner orbits, 

 dilated above and extending beyond the eyes, the greater part of the malar space, 

 a narrow line on pronotum, tegulae and base of mandibles, pale lemon-yellow ; legs 

 darker-coloured than the body, the femora and apical two-thirds of hind coxae 

 blackish, the anterior 4 coxae infuscated; the basal joints of antennae blackish. 

 Female. 



Length, 5 mm. ; ovipositor, almost 1 mm. 



The sculpture is as in the preceding species, from which, apart from the difference 

 in coloration, it may be known by the radius not extending beyond the 2nd trans- 

 verse cubital nervure, and in both the transverse cubital nervures being only indi- 

 cated posteriorly, not reaching to the radius ; the 2nd is short, through the cubitus 

 converging towards the radius.
