plainly but shallowly emarginate in the middle; sides broadly 

 curvate, subparallel curving into tbe faintly incurvate hind- 

 margin ; hindmargins of meso- and metanotum plainly angularly 

 emarginate. 



Body with head fully extended 7 to 8; body with wings 14; 

 forewing with stump 13 ; span 27 ; headwidth across eyes 1 • 18 to 

 1 • 25 ; diameter of eyes from above • 28. 



Locality): DamaralanD: (The Dornveld near Windhoek). 

 Collected by Dr. Hartig. 



Remarks: Dr. Hartig also collected a soldier and some 

 workers in the same place at a later date which may belong to 

 this species. The head of the soldier is elongate, sides sub- 

 parallel and faintly curvate; mandibles just half the length of 

 the head; labrum reaching but a Itttle over basal half of 

 mandibles; Antennas broken, III large and plainly compound, 



III longer than either IV or V and as long as II. Total length 

 2-9; head with mandibles 1*3; headwidth 0* 67. The workers 

 are in two castes. Majors with sub-rectangular heads longer than 

 wide; antennze XIII jointed, III minute. Headwidth 0-74 to 

 Or 75. Minors with sub-circular heads. Headv^dth 0-60. 

 Antennae brokea. According to Holmgren's tables (1913) the 

 imago should stand near the insect therein mentioned, but not 

 described, as M. alhonohis. 



Microtermes eiiolatus sp.n. 



Imago. Head contrasting sharply with remainder of body; 

 wings hyaline, C. and R. black brown in basal sixth only, 

 remainder blanched ; M. and Cu. obliterated. Distinctly different 

 at a glance from all our other species of Microtermes. 



Head above warm ferruginous; eyes black; clypeus very pale 

 yellow and contrasting strongly, with a fine dark median line; 

 antennse pallid. Pronotum pale uniform yellow with a pair 

 of red brown flecks in transverse furrow; sometimes slightly 

 dimmed with brown when pale cross can be discerned. Meso- 

 and metanotum pale yellow : Tergites of abdomen cream coloured 

 dimmed slightly with brown. Sternites creamy. Legs quite 

 pale ; tibia faintly darker with a brown spot near femoral articu- 

 lation. 



Antennse XVI or XV jointed; when XVI jointed, III smallest, 

 when XV jointed IV a little longer than V; occasionally XV 

 when III long and plainly compound; occasionally XVI with III 



IV very short. Ocelli prominent, roundly oval less than half 

 long diameter from eyes (4:11). Pronotum almost as wide as 

 !head with eyes, not twice as wide as long (13: 21) ; front margin
