vein at base and in middle, a stripe on vein bounding inner margin of discoidal 

 area, another along origin of vein running from apex of discoidal area, and the 

 reticulation of the broad median region of costal area, all sordid yellow ; larger 

 cells of membrane towards apex greyish fuscous. Legs yellow, apices of tibiae 

 and tarsi infuscate. Venter black. 



Structure. — Head twice as wide as long (24 : 12) ; vertex twice as wide 

 as width of an eye (12 : 6) ; relative lengths of antennal segments, 12 : 7 : 57 : 32. 

 Pronotum about five-eighths as wide across widest part as long from anterior 

 margin of collar to posterior apex (54 : 83) ; paranota about twice as long as 

 greatest breadth 63 : 52 ; coarsely reticulate about 24 cells visible from above 

 on each lobe, the veins thick ; the inner marginal vein with a few moderately 

 long hairs ; length of pronotum visible posteriorly, equal in length to anterior 

 collar in middle ; median carina strongly elevated. Hemielytra widest at level 

 of apex of pronotum, about half the total length (64:125); reticulation of 

 membrane cells equal in size to those of middle of costal area ; reticulation of 

 discoidal area rather less coarse and of subcostal area moderately fine ; veins 

 of discoidal area with a few moderately long erect hairs. Bucculae finely 

 reticulate ; propleura obsoletely punctate posteriorly. 



Total length, 2-8 mm. Greatest breadth of pronotum, 0-9 mm.
