durbanensis in having the front margin of the pronotum angularly 

 indented in the middle. The labrum is longer than that of dur- 

 banensis, always covering more of the base of the mandibles. 



Genus NEOTERMES Holmgren (1911). 



Neotermes zuluensis Holmgren. 



Holmgren has described a tpecies under this name from ma- 

 terial collected by Ivor Triigardh at Lake Sibayi, Zululand. The 

 species is founded on the soldier form, the imago being unknown. 

 The published description is very imperfect, and as far as it goes 

 might relate to durbanensis. The imagos of Neotermes differ 

 strikingly from those of Calotermes inasmuch as the Media runs 

 close to and parallel with the Radius whilst in Calotermes it lies 

 about half way between the Radius and Cubitus. I have not 

 met with any imagos or soldiers of Neotermes up to the present. 



Genus CRYPTOTERMES Banks. 



Cr^ptotermes merwei sp.n. 



This termite is to be found at a number of points along the 

 Natal coast. The nests are always in the dead stubs left where 

 limbs have broken away from living trees. Although interming- 

 ling with Calotermes durbanensis it favours more the flora of the 

 sand dunes behind the sea beaches. However, I have received 

 imagos that cannot be separated from the Natal form from the 

 Albany Museum. These were obtained from the Brak Valley, 

 Grahamstown. 



The imago of merwei answers well to the description given 

 by Sjostedt for C.Havilandi from Senegal, etc. It is, however, 

 a little smaller and may differ in features not touched upon in 

 Sjostedt's description. The soldiers are very diffeient from those 

 of havilandi as described by Silvestri. The frontal ridge of the 

 head is very slightly incurvate, almost straight. In this it differ? 

 from havilandi, senegalensis and pseudobrevis. The clypeo- 

 apical is short, wide, and the front margin distinctly incurvate. 

 The labrum is wide, somewhat heart-shaped in outline; the tip
