ERIC MJÖBERG, ISOPTERA. 79 



cate in front, thickly hairy, with numerous small yellow 

 rounded spöt and a light median line on the anterior half 

 part and a broad, curved yellowish cross-band, tapering 

 strongly to the base, excised in the middle of the hind 

 margin; wings greyish-brown, long, rounded at tip, the ner- 

 vature very curious and variable; the two stout nervures 

 running out to the tip, between them at the tip many small 

 cross nervures (6—8), also below the second very stout ner- 

 vure there are on the exteriör half of the wing numerous 

 oblique irregular veinlets running out into the membrana 

 and ending freely; mediana runs very high up in the wing, 

 giving off, as a rule, at a distance of about two third 

 parts of its length from the base, three long simple or 

 forked branches, but in an other case (see Text Fig. 39 a) only 

 one, which joins a branch of cubitus ; also in the spaces 

 between the branches of cubitus there are some irregular 

 veinlets; cubitus is richly developed, with about 8 — 12 oblique 

 branches to the hind margin; also the venation of the hind 

 wing is ver}^ variable; mediana is richly developed and sends 

 out a number of branches, which here and there are anastoraotic 

 with eachother; in the specimen figured (Text Fig. 39 a) there 

 is an off-branch running out into the space between the 

 second stout nervure and mediana, coramencing already a 

 bit away from the base; there is also an anastomosis between 

 mediana and cubitus; in both the winged insects which I 

 have at my disposal there is a remarkable irregularity in 

 the venation of the wings, which I have never found in any 

 other Australian termite; legs of moderate size; abdomen 

 with parallel sides, with 9 chitinous dorsal plates.

Soldier (Text Figs. 36 c, 41 c). Easily recognizable 

 b}^ its bright reddish-yellow% very high, convex and large 

 head, the long jaws, provided with a strong but not 

 sharp median tooth and the fairly long and slender-jointed 

 antennae with the 3rd and 4th joint coalescing. 



Head large, convex and rounded behind, sloping down
