Centre of basal segment raised, narrowed at the base, clearly 

 separated. 



Mesaagathis, gen, no v. 



Malar space large, bnt not quite so long as the eyes, the face 

 not much narrowed ])elow ; apex of clypeus broad, transverse ; 

 the face broadly raised in the middle, foveate laterally at the apex; 

 the labrum large, broadly rounded at the apex. Front not exca- 

 vated. Occiput roundlj^ incised. Radial cellule short, not reach- 

 ing to the middle of the apical part of the margin ; 1st cubital 

 and 1st discoidal cellules confluent ; areolet almost square ; 

 transverse basal nervare interstitial. Hind wings with a closed 

 discoidal cellule. Foreclaws cleft. Calcaria very short. Apex of 

 median segment transverse, the sides slightly roundly projecting: 

 in the centre is a large area which extends to the top of the apical 

 slope ; beneath it is a small, broader than long area ; the sides are 

 margined ; the spiracles moderately large and long. 



The trophi are elongated ; the maxillary palpi 5-jointed; the 

 parapsidal furrows distinct, the middle lobe of mesonotum clearly 

 separated. Abdomen (in male) sessile, shorter than the thorax. 

 Legs stout, the metatarsus as long as the following 3 joints united. 

 Mandibles curved, longish, edentate. Scape of antennae fully 3 

 times longer than thick, nai rowed at the base. Apex of scutellum 

 transverse, margined. 



The malar space is not quite so long, nor so much narrowed 

 below as in the typical Agathidini, but it is longer than in the 

 typical Micrudini. In some respects it approaches Disophrys, but 

 the hollowed front with keels separates that genus. 



Mesoag<fthis fuscipennis, sp. nov.

 of hind tibiae and hind tarsi black ; wings dark fuscous, iridescent^ 

 the nervures and stigma black. Male.

Grahamstown, November : Misses Daly and Sole. 



Antennae as long as the body. Face and clypeus thickly, the 

 i-est of the head sparsely covered with long white hair ; the raised 

 central part of the front bordered on the outer side by a stout 

 keel ; in the centre is a naiTower keel. Pro- and mesothorax
