the occipital margin. The thorax is considerably constricted at the 

 meso-epinotal suture, which is fairly deep. The pro-niesonotum 

 is very convex transversely in front. The dorsum of the epinotum 

 is barely half as long as the pro-mesonotum and slopes downwards 

 towards the declivity, with which it forms a rounded but distinct 

 angle. The declivity is nearly vertical and half as long as the 

 dorsum. The epinotum widens at the brow of the declivity, where 

 the margins are rendered somewhat tumid by the median excavation. 

 Nodes similar to those of Junodi.

^ . 2 - 8 mm. Exceedingly similar to var. willowmorensis, which it 

 resembles in colour and sculpture. It is smaller than that variety, 

 and the pro-mesonotum is narrower, and less convex at the sides 

 behind the shoulders. The meso-epinotal suture is not so deep, and 

 the thorax is less constricted at that point. The epinotum is also 

 narrower across the brow of the declivity. The peduncle of the 1st 

 joint of the petiole is also a little longer, the node more pointed above 

 and narrower. The dorsum of the epinotum is flatter.

" ^ • 19-2 mm. This bears a close resemblance to M. setuliferum, 

 Forel, from which it differs by the much longer head (one-quarter 

 longer than wide), and by the nodes. The 1st is higher and also 

 wedge-shaped (but rounded above), the 2nd is much smaller and 

 lower. The thorax is like that of Salamonis, whereas in setuliferum 

 both the pro-mesonotum and the epinotum form equal longitudinal 

 convexities. In damarense, only the pronotum anteriorly is abruptly 

 convex, the dorsum of the thorax is but slightly convex, only feebly 

 indented, and the angle between the two planes of the epinotum is 

 fairly sharp, though rounded ; the declivity is much shorter than the 

 dorsum. The scape hardly extends beyond the occipital margin. The 

 eyes are rather flatter and are placed more posteriorly than in 

 setuliferum. Closely reticulate-punctate and dull (not so closely as in 

 setuliferum and not rugose) . Abdomen in greater part shining and 

 smooth. Pubescent, with scanty and erect hairs on the abdomen.
