34. Genus TANNA, Distant 



Tanna. Distant, Ann. Mag. Nat. Hist. (7), Vol. i5, p. 61 (igoS). 



Characters. — Head (including eyes) narrower than base of mesonotum and about as long as 

 space between eyes; lateral margins of pronotum angularly sinuate, but not prominently toothed; 

 abdomen much longer than space between apex of head and base of cruciform elevation ; tympana 

 covered; opercula small, not or scarcely extending beyond base of abdomen; rostrum reaching the 

 posterior coxae; tegmina and wings hyaline. 



Closely allied to Leptopsaltria, from which it differs by only having a lateral tubercle on the second 

 and not on the third ventral segment, in other respects resembling the genus Pomponia. 



Type. — T. japonensis, Distant. 



Geographical distribution of species. — India, Malayan Archipelago, Japan.

 completely covered; opercula in male long and extending beyond middle of abdomen; rostrum scarcely 

 reaching the posterior coxae; anterior femora spined; tegmina and wings hyaline, the first with the 

 venation normal, the apical areas eight in number, the basal cell twice as long as broad.
