"West Africa" (British Mus., type); Togo (Berlin 

 Mils.). 



The species is to be distinguished by the broad testa- 

 ceous margin running all round the pronotum and by 

 the apical three-fifths of the tegmina being hyaline, the 

 castaneous colouring of the tegmina occupies the basal 

 two-fifths, and is produced along the marginal field towards 

 the apex. 



4. Ct. castanen, sp. n. 



^. Differs from scutelligera and costcdis by the greater distance 

 apart of the eyes on the vertex of the head. Head rufo-testaceous, 

 vertex between the eyes, which are nearly 1 mm. apart, castaneous. 

 Pronotum with disc castaneous, margins broadly flavo-testaceous, at 

 the postero-lateral angles the castaneous almost reaches the outer 

 border of the pronotum. Tegmina dark castaneous, flavo-marginate 

 almost to their apex. Wings suffused with castaneous. Abdomen 

 and legs as in the preceding species. 



Total length, 16 mm. ; length of body 14'8 mm. ; length of tegmina 

 14 mm. ; pronotum 5 mm. x 6 mm.
