3-5 pairs of long setae on the vertex behind the constriction, and E. abruptus and 

 E. undulans have thinner noses with different profile. 



Holotype $ imago, allotype <$, morphotype soldier, and paratypes from type 

 colony. Ghana : 20m. from Bolgatanga on Tamale Road, 9.111.1959 (W. A. 

 Sands, Coll. No. S.2364), in British Museum (Natural History). 



Other paratype material. Ghana : Awura, 4m. from Ejura on Kintampo Road, 

 28.iii.1959 (W. A. Sands), soldiers and workers.

This species has been recorded from the edge of the forest-zone to the Northern 

 Guinean savannah (Keay et al., 1959, vegetation types 8, 16, and 17). 



Eutermellus bipartitus (Sjostedt) 



(Text-figs. 403, 404, 420, 421, 484 ; Map 30) 



Eutermes bipartitus Sjostedt, 1911 : 168. Type locality : Congo, Mukimbungu.

 Eutermellus bipartitus (Sjostedt) Sjostedt, 1926 : 358. 



Imago. Colour probably faded in old specimen. Described by Sjostedt as having head 

 capsule chestnut brown, dorsal sclerites pale red-brown. 



Posterior margin of head capsule evenly rounded, less than semi-circular, turned slightly 

 outwards at eye rim ; fontanelle pale, elongate triangular, somewhat rounded, with indistinct 

 oval mark in front ; eyes oval, slightly but distinctly set out from sides of head, prominent in 

 proportion to own diameter and fairly large relative to head width, W/E index 2-9 ; ocelli 

 medium-sized, oval, separated from eyes by slightly more than one-third own least diameter ; 

 postclypeus moderately inflated, width 2-i times length, anterior margin nearly straight, 



and V subequal, 

 ', pronotum and 



13 



posterior convex, evenly rounded ; antennae probably 15 segmented, II, IV 

 III shorter. 



Pilosity of head dense, not sufficiently even to form a " pelt " or " mat " 

 abdominal pilosity similar, longer towards margins of sclerites. 

 Measurements (1 specimen) in millimetres. 



Head width across eyes ..... 0-89 



Greatest diameter of eye . . . . . 0-31 



Ocellus . . . . . . . . 009 x O' 



Ocellus to eye ....... 0-03 



Width of pronotum ...... o-68 



Length of pronotum ...... 0-46 



Length of hind tibia ...... 1 -20 



Soldier. Head capsule pale yellow to yellow, nose orange-yellow to orange, rest of body 

 cuticle pale yellow. 



Head capsule in plan view weakly constricted behind antennae, posterior margin evenly 

 rounded ; nose rather thick, conical. In profile almost straight or slightly convex, with slight 

 depression behind base of nose and in front of evenly rounded posterior lobe ; antennae 13 

 segmented, II, III and V subequal, IV shorter. 



Conspicuous setae of head consist of four to six in two or three pairs in line across base of nose 

 in front of constriction, and one or two pairs similarly arranged on posterior lobe behind con- 

 striction.
