The broad abdomen and the obsolescent venation of the menibranous tegmina 

 are the charaeteristic features of this species. Obsolescent venation is usually asso- 

 ciated with a corneous and more or less opaque texture of the tegmina, its dis- 

 appearance from delicate menibranous tegmina is niost unusual. 



Ceratiiioptera castaiiea sp. n. 



c^. Allied to C. ahbreviafa Sauss. and C. madecassa Saüss. but differing from 

 the former by its larger size and by the different shape of the sub-genital lamina and 

 from the latter by the shorter tegmina. 



Dark castaneous. Antennae fuscous, month parts testaceous. Pronotuni trape- 

 zoidal, nearly covering Vertex of head lateral margins rufo-castaneous, its posterior 

 margin slightly obtusely angled. Tegmina lanceolate, corneous, extending to the 4*'» 

 abdominal tergite, 10 costals, anal vein impressed, remainder of venation obscured. 

 Wings much reduced, extending to middle of 2"'i abdominal tergite. Supra-anal 

 lamina transverse, slightly produced. Sub-genital lamina broad, transverse, slightly 

 produced, its posterior angles rounded, with two short styles. Legs rufo-testaceous. 



Length of body 12 mm.; length of tegmina 7 mm.; pronotum 4 mm. x 5 mm.

Ceratiiioptera sjöstedti sp. n. 



(PI. 3, tigs. 16—17.) 



c?. Allied to C. ferruginea Schulth but with longer tegmina. Rufo-testaceous. 

 Head castaneous, antennae testaceous at base, remainder infuscated; vertex of head 

 not nearly covered by pronotum. Pronotuni transversely elliptical with lateral margins 

 lu'aline, posterior border truncate, exposing the scutellum. Tegmina extending to 

 penultimate segnient, menibranous; marginal field very broad, 12 costal veins, anterior
