and the first and second marginals are in line instead of overlapping slightly. The 

 fontanelle and large eyes are also very distinctive.

Imago. Head capsule orange-yellow, clouded with brown between eyes and on frons, darkest 

 on upper rim of ocelli ; postclypeus and labrum, yellow, antennae yellow-brown. Pronotum, 

 meso- and metanota, other thoracic sclerites and legs, yellow. Abdominal tergites brown, 

 sternites pale yellow-brown, paler in mid-line. Wings translucent very pale brown, venation 

 brown, darker at base ; radius sector with brown inner margin, and with adjacent yellow streak 

 in distal half of wing. 



Posterior margin of head much less than semi-circular behind eyes, slightly sinuate im- 

 mediately behind eyes ; eyes oval, very prominent, and large relative to head width, W/E 

 index 2-4 ; ocelli large, oval, scarcely separated from eyes ; postclypeus strongly inflated, 

 width i-8 times length, anterior margin straight, posterior regularly convex ; antennae 15-16 

 segmented, II and IV subequal, III longer, or II and III subequal, IV shorter. 

 Cerci of $ mamilliform, shorter than width across base. 

 Pilosity of vertex confined to a few long paired setae. 

 Measurements (4 specimens from 2 localities) in millimetres.

Soldier. Head capsule yellow to orange, nose orange to ferruginous. Pronotum, antennae 

 and abdominal tergites orange-yellow, legs and abdominal sternites yellow. 



Head capsule in plan view with angularly rounded posterior margin. In profile depressed 

 behind base of nose or straight in front of raised posterior lobe ; nose shorter to longer than rest 

 of head measuring from hind margin of antennal socket, maximum angle of taper 5 degrees ; 

 antennae 14 segmented, elongate, II short, IV, V and VI subequal, longer than II, III longer 

 than these, twice length of II. Setae on head confined to four at nose tip and a bilaterally 

 placed pair on vertex. 



Abdominal tergites almost glabrous except for 4-6 long yellow setae on posterior margins of 

 each of last 4-5 segments ; sternites with scattered very sparse short setae and longer setae on 

 posterior margins 3 or more times length of short. Remaining characters given in generic 

 diagnosis.
