Division G .E A N A R I A. 



This division, at |)resent ix'preseuted by tlu'ee Eastern 

 genera, is to be principally recognized by the following 

 characters : — The tcgmina and wings are opaque and generally 

 more or less brilliantly coloured ; the lateral margins of the 

 pronotum are neither am]jliated nor dilated; the tympanal 

 orifices are largely exposed, the tympanal coverings being a 

 little narrower and much shorter than the orifices, and with 

 their anterior margins convex. 



Si/uopsis of Genera. 



A. Tegmina with the venation normal ; apical areas eight. 



a. Head longer than pronotum, front somewhat porrectly 

 produced. 

 b. Greatest breadth of tegmina more than one third of 



their length Gceaiia. 



aa. Head not longer than pronotum, obliquely depressed in 

 front of eyes. 

 bb. Greatest breadth of tegmina only about one third of 



their length _. Balinta. 



B. Tegmina with the venation reticulate, ulnar and apical 



areas broken up into many cellular divisions Talainga,

 notum and as long as pronotum, obliquely depressed in front 

 of eyes ; pronotum about as long as niesonotum, its lateral 

 margins sinuate, the posterior angles moderately dilated; 

 abdomen in male much longer than space between apex of 

 head and base of cruciform elevation ; tympanal coverings
