Descriptions of Nctv Species of Parasitic Hymenoptcra. 133 



band narrower, and the whole of the other segments except for 

 a narrow black band at the base, rufous. Legs entirely rufous. 

 Antennae of a duller rufous colour. Wings hyaline, the apical half 

 of the radial and the whole of the apical cubital cellule smoky ; the 

 costa and stigma fulvous, the nervures black, g 



Length 12 mm. 



Cape Colony. 



Face somewhat strongly punctured, the clypeus and labrum more 

 closely rugosely punctured. Front closely punctured, the lower part 

 closely transversely striated ; the part immediately below the ocelli 

 shining, smooth, except for a few keels. Thorax closely rugosely 

 punctured, the punctures running into reticulations in the centre of 

 the mesonotum. Scutellum more strongly rugosely punctured than 

 the mesonotum, the keels bluntly rounded at the apex. Metanotum 

 with two stout keels in the middle, extending from the base to the 

 apex, where they are roundly curved. Mesopleural furrow wide, 

 shallow. All the abdominal segments are longer than wide ; the 

 basal strongly, the apical weakly punctured ; their apices are trans- 

 verse. Areolet sessile ; the recurrent nervure is received at the base 

 of the apical third. 



This species differs from the other Cape forms in the greater 

 expansion of the rufous colour and in the absence of yellow ; in the 

 areolet being sessile, and in the recurrent nervure being received 

 beyond the middle. 



Metopius nigro-ornatus, sp. nov. 



Black, the face, a broad line on the lower half of the upper inner 

 orbits, a longish broad line on the centre of the pronotum, reaching 

 nearer to the apex than to the base, tegulae, scuteilar keels, apical 

 half of scutellum, post-scutellum, an irregularly oval spot on either 

 side of the apex of the metanotum, tubercles, a lai-ge mark on the 

 base of the mesopleurae, commencing near the top and extending 

 below the middle, about twice longer than broad, rounded above, 

 transverse below and of equal width throughout ; a band on the apex 

 of the first abdominal segment, largely dilated laterally, and narrower 

 bands, also dilated laterally, on the apices of the others, pale whitish 

 yellow. Four front legs whitish yellow, the femora with a broad 

 rufous line on the base above ; the hind legs red, the coxae black, 

 except for a large mark, oblique, narrow at the base, broadly dilated 

 towards the apex, the basal joint of the trochanters, a large line, 

 dilated at the top, on the under side of the femora, and a smaller one
