The Termites of South Africa 71 



Genus allodontermes 5ilvestri. 



Allodontermes schulizei (Silv.) 



The type localities for this species are Severella and Kang- 

 Kgokong which lie in the heart of the Kalahari some 300 miles 

 west of the Transvaal boroer. The species has also been recorded 

 from Zululand by Holmgren (1913). I have a number of 

 images from. Modder River Rail (Griqualand West) , Klerksdorp, 

 De Wildt, Pretoria (Transvaal), all in entire agreement with one 

 another and fully answering Silvestri's description. 



Series of soldiers have been examined from the Lebombo Flats 

 (Swaziland) ; Mokeetse, De Wildt, Marico, Warmbaths, 

 Naboomspruit, Klerksdorp, Pretoria (Transvaal) ; Glen Lyon 

 (Griqualand West). These series of soldiers vary in their average 

 measurements. According to the size of the soldiers the dentation 

 of the mandibles differs within certain limits and the rule seems to 

 be that the smaller the head the less massive are the mandibles 

 and the more decided the dentation. 



The following criteria relate to the material here enumerated. 



WmgecL Imago : Antennie XIX. jointed ; pattern, on the whole, 

 very regular; joints III. and IV. sub-equal, V. smaller than 

 either lY. or VI., VII. slightly smaller than VI. and VIII. Body 

 with head fully extended 11 -5 to 13 ; body with wings 21 to 23 : 

 forewing with stump 18 to 20; span 37 to 41; headwidth across 

 eyes 1-75 to 1 • 81, between eyes 1-25 to 1 * 37. 



Soldier: Antennae XVII. jointed; joint iV. larger than III. or 

 V. but smaller than VI. Total length 4 to 5 • 5 ; head with mandi- 

 bles 2-0 to 2-6; headwidth 0*93 to 1-22; left mandible 0*76 

 to 0-91. 



Worker: All the major and minor workers I have examined 

 have antennae of XVII. joints with joint IV. always larger than 

 either III. or V.; III. the shortest joint, about half the length 

 of II. A major from Glen Lyon whilst possessing a large joint 

 IV. has III. relatively large and exhibiting a pseudo-articulation. 

 The headwidths of the major workers vary from 1 -• 06 to 1 • 25. 

 of the minor workers from 0-87 to • 93. 



Allodontermes schultzci sub.sp. orienialis s.sp.n. 



The imago upon the whole darker than schultzet and generally 

 plainly shorter bodied and with shorter wings. Body with head 

 extended 9*7 to 10; body with wings 19 to 20; forewing 16
