along its sides a wide curved furrow ; the second and third segments are 
closely, rather strongly punctured, the others sparsely and weakly so.

Lemana (Zoutpansberg District). November. 
Face closely, irregularly, longitudinally striated in the centre, the 
lower part of this striated part bordered by curved furrows ; the sides 
above with a few weak punctures. Clypeus and labrum smooth, shining, 
sparsely covered with white hair ; the front and vertex smooth, shining, 
punctured between the ocelli. Legs black, the four anterior femora and 
tibiae largely infuscated, the anterior more largely so than the middle ; 
the second, third, and base of fourth joint of the hinder tarsi white ; the 
tarsi covered with short white spines. 
This species, of those known to me, comes nearest to M. lissonotus, 
Cam. ; the following are the essential differences between the two

Valoga, gen. n. 
Metanotum closely, transversely striated ; there are two keels down 
the middle of the basal half ; the spiracles small, round. The only trans- 
verse cubital nervure is short, the radius and cubitus nearing each other 
at it ; the recurrent nervure is received four times its length beyond it ; 
transverse median nervure almost interstitial ; the disco-cubital nervure 
rounded, unbroken ; the transverse cubital nervure in hind wings broken 
shortly below the middle. Third joint of antennae longer than the fourth ; 
there are twenty-seven antennal joints. There is a raised tubercle in the 
centre of the face near the clypeus, which is not clearly separated from 
the former. Malar space furrowed, one-third of the length of the eyes. 
Ocelli in a curve, separated from the eyes by a slightly greater distance 
than they are from each other. Occiput margined. Scutellum raised, 
smooth, keeled laterally at the base. Basal three abdominal segments 
closely striated ; the first becomes gradually widened from the base to 
the apex ; the ovipositor is half the length of the abdomen. The wings 
are clouded. 
This genus may be known by the absence of areae on the metanotum. 
It is not unlike the South African genus Lievella , Cam., which wants also 
the first transverse cubital nervure, but it has the metanotum regularly 
areolated.
