This division, at present represented by three Eastern genera, 

 is recognized principally by the following characters : — The 

 tegmina and wings are opaque and generally more or less brilliantly 

 coloured ; the lateral margins of the pronotum are ne ither 

 ampliated nor dilated ; the tympanal orifices are largel}' exposed, 

 the tympanal coverings being a little narrower and much shorter 

 than the orifices and with their anterior marsius convex. 



Synopsis of Genera. 



A. Tegmina with the venation normal ; apical areas 



eio'ht. 

 a. Head longer than pronotum, front somewhat 

 porrectly produced. 



a. Greatest breadth of tegmina more than one- 



third their length G^ana, p. 145. 



h. Head not longer than pronotum, obliquely 

 depressed in front of eyes. 



b. Greatest breadth of tegmina only about one- 



third their length Balinta, p. 148. 



B. Tegmina with the venation reticulate, ulnar and 



apical areas broken up into many cellular 



divisions Talainga, p. 150.
