Hemiblabera, Saussure, Societas Entomologica, 1893, p. 68. 



Caput obtectum, sat compressum, vertice parum crasso, a pronoto valde superatum, fronte planulo. Pronotum 

 et elytrorum margo lateralis marginata. Elytra cornea, $ sese intus haud vel levissime tegentia, 

 c? variabilia ; alse in utroque sexu minimse. Femora subtus in margine antico spinis paucis ; femora 

 anteriora et intermedia spinis apicalibus 1 : 2, posteriora 1 : 0. Lamina supra-analis minute incisa. 



* No female has ever been obtained which could be assigned to this species, based on males only. From 

 this circumstance we think it probable that B. fumigata is not different from B. thunbergi, the former being 

 based on males with completely developed wings, while B. thunbergi (tf) has been established on individuals 

 with abbreviated wings.
