?. Body and Icji^s black, soniowliat opaque; head with 

 the basnl hiteval maruins of" lace, the space between face and 

 eyes and the anterior angles of vertex above, pronotum with 

 the lateral and posterior margins (tke last attenuated and 

 almost broken at centre) and two dentate spots on anterior 

 margin, mesonotinn with the basal lateral margins, the poste* 

 rior disk (which has two black s|)ots), and tiie cruciform 

 elevation and the lateral margins of the prosternum pale 

 green. 



Tegmina piceous, opaque, the costal membrane and costal 

 area pale green, the venation castaneous ; a broad creamy- 

 white transverse fascia commencing at end of radial area, 

 ■where it is broadest, and terminating on lower apical area, 

 where it is attenuated, and with some pale brownish longitu- 

 dinal streaks in ulnar and apical areas; wings black, some- 

 what shining, with some pale brownish streaks near apices of 

 apical areas, the largest on abdominal area. 



liostrum passing the posterior coxje. 



Allied to T. montivarja, Dist. ; apart from some colour- 

 ditferences, it differs principally from the corresponding sex 

 of that species by the much greater width of the tegmina 

 in wings. In T. montivaga ? the greatest width of the 

 tegmina is only equal to one third of their length, in T. See- 

 hohmi ? it is considerably more tiian one third of their 

 length ; the apices of both tegmina and wings are also much 

 broader and less oblique. 



Long., excl. tegm., 5 45 mm. ; exp. tegm., $ 148 ram. 



Hah. Formosa: Lak-kuii (//o/^Y, Brit. Mus.). 



The specimen on whicii this species is founded formed part 

 of the bequest made to the British Museum by the late 

 well-known ornithologist Henry Seebohm, to whom I have 

 dedicated its specific name. 



Division T ii P H A R I A. 



Tympana very strongly developed and sac-like, projecting 

 beyond the lateral margins of the abdomen and extending to 

 about half its length ; opercula very small, not reaching 

 base of metasternum ; lateral margins of pronotum almost 

 truncate ; tegmina and wings talc-like, semihyaline. 



Synopsis of Genera. 



A. Pronotum very broad, its breatlth equalling length of both 

 pro- and mesonotuni (including the cruciform basal 

 elevation). 

 a. Head between eyes as broad as base of niesonolum .... Thopha.
