JMr. W. L. Distant on llomoptern. 301 



Tosena Seehohmi^ sp. n. 



?. Body and legs black, somewhat opaque; head with 

 the basal lateral margins of face, the space between face and 

 eyes and the anterior angles of vertex above, pronotum with 

 the lateral and posterior margins (the last attenuated and 

 almost broken at centre) and two dentate spots on anterior 

 margin, mesonotum with the basal lateral margins, the poste- 

 rior disk (which has two black spots), and the 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. 



Eostrum passing the posterior coxae. 



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

 differences, 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 2\ See- 

 bohmi $ it is considerably more than one third of their 

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

 broader and less oblique. 



Long., excl. tegm., $ 45 mm. ; exp. tegra., ? 148 mm. 



Bah. Formosa: Lak-kuli {Hoist, Brit. Mus.). 



The specimen on which 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 Thophakia. 



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 metasternuni ; lateral margins of pronotum almost 

 truncate ; tegmina and wings talc-like, semihyaline. 



Synopsis of Oenera. 



A. Prouotum very broad, its breadth equalling length of both 

 pro- and mesonotum (including- the cruciform basal 

 elevation). 

 «. Head between eyes as broad as base of mesonotum .... Thopho.
