Subfam. CicABiNJL (continued from vol. xiv. p. 430). 

 Division Dundubiaria. 



This division is composed almost entirely of Oriental, 

 Malayan, and Australasian species, save a few derived from 

 the extreme east of the Palaearctic Region, which, as well 

 known, possesses a strong Oriental affinity. 



The lateral margins of the pronotum are distinctly angu- 

 lated or toothed ; the tegmina and wings hyaline, sometimes 

 spotted, but never opaque ; the opercula vary much in length 

 and shape, and in some genera reach the maximum of 

 development. 



This division is a very homogeneous one, but at the same 

 time one of the most ditiicult to readily analyze. It is hoped 

 that the following proposed generic revision will considerably 

 assist specific determination. 



Synopsis of Genera. 



I. Second and tliu'd ventral se;2ments in c5' with distinct 



lateral tubercles ; opercula short. 



A. Head (including eyes) considerably narrower than 



base of mesouotum Leptopsaltria, 



B. Head (including eyes) as wide as base of meso- 



notum. 

 a. Head as long as space between eyes. 

 b. Tympanal coverings in (S broader at base 

 than long. 

 c. Abdomen moderately conical, gradually 

 attenuated posteriorly, in J considerably 

 longer than space between apex of head 



and base of cruciform elevation Purana. 



aa. Head as long or a little longer than space be- 

 tween eyes. 

 bb. Tympanal coverings in S as long as breadth 

 at base, or sometimes broader tlian long. 

 cc. Abdomen broad, about as broad at apex 

 as at base ; in J not longer than space 

 between apex of head and base of cruci- 

 form elevation Maua. 



II. Second ventral segment in S alone provided with 



lateral tubercles ; opercula short Tanna. 



III. Ventral segments without tubercles; opercula 

 short or sometimes very long, and very variable in 

 shape. 



C. Head with the front large and convex, about 



twice as broad at its base as the anterior mar- 

 gins of the lobes of vertex ; rostrum scarcely 

 reaching the posterior coxte Dunduhia.
