Hab., Museum Grounds, Grahamstown. 



Smooth, shining, almost bare. Scutellum bifoveate at the

Schdtilandella trrmaciilafa, sp, now 



Length 5 mm. Female. 



Hab., Grahamstown. 



This species may be separated from S. nigromncnia as follows: 



Pleurae, steraum, base of metanotum, and base of legs black ; 

 wings fuscous, the nervures and stigma black- fnigy'omacuhitaj. 

 Mesosternum only black ; the wings almost hyaline, the nervures 

 testaceous, ftrimaculataj. 



The middle lobe of mesonotum is entirely black and the 

 lateral for the greater part ; the colour of the body wants the 

 reddish tint of nigromacuUita, it being jellowish testaceous ; the 

 legs are similarly coloured with only the apex of the hind tibise 

 and the hind tarsi black ; the area on the metanotum has not the 

 basal keels so clearly defined ; the vertex is black • the black mark 

 on the front becomes gradually narrowed towards the base of the 

 antennae ; the 2nd transverse cubital nervure is pale. 



SchdnlcwdeUa nigricnJJis, sp. hov. 



Black, thickly covered with a white down ; the abdomen, 

 except the apical segment, and the legs, except the coxae and the 

 posterior tarsi, rufo-luteous ; wings fuscous, paler at the base, the 

 costa and base of stigma luteous, the rest and the nervures black. 

 Female. 



Length 6 mm.

 apex. Scutellar depression closely, stoutly striated, as is also the 

 depression at the sides of the post-scutellum. Median segment 

 opaque, closely rugose. Tibiae and tarsi densely, shortly pilose.
