narrowest posteriorly; posterior iialf transversely striate. Tegmina 

 with basal two-fifths castaneous, apical three-fifths testaceous with 

 a large castaneous spot near the apex of the margin ; the line of 

 demarcation between these two coloured areas is V-shaped and 

 finely dentate. Abdomen and legs orange. Supra anal lamina sub- 

 quadrangular, sub-genital lamina asymmetrical, styles minute. 

 Gerci pointed, orange. 



Total length 16 mill.; length of body 12,7 mill.; length of 

 tegmina 14 mill. ; pronotum 4,3 mill. X 5,2 mill. 



BenaBendi, Sankuru River (L. Cloetens), Popocabacca (F. Loos). 



Congo Free State. Two examples. Allied to G. gloriosa StAl but 

 smaller and differently coloured. 



NAUPHCETA SORDID A sp. n. 



9. Dull sordid testaceous. Antennas fuscous, eyes wide apart. 

 Pronotum uniformly coloured with a few scattered fuscous points, 

 some larger ones arranged round the margin. Tegmina not exceed- 

 ing the apex of the abdomen by much, uniformly sordid testaceous 

 with scattered l)lack points, the extreme base of the radial vein 

 piceous, mediastinal area rather narrow. Abdomen dull pale 

 castaneous, supra-anal lamina bilobed. Legs dull testaceous spotted 

 with castaneous points. 



Total length 31 mill. ; length of body 27,3 mill. ; length of 

 tegmina 24 mill. ; pronotum 7 mill. X 9,8 mill. 



Cameroons, Mukonje Farm (R. Rohde). Two examples. 



This dull-coloured species presents a great contrast to the bright 

 testaceous species so characteristic of West-Africa ; its nearest ally 

 appears to be A^. heydeniana Sauss. & Zehnt. from Madagascar, but 

 that species has the tegmina shorter and is not spotted with black 

 points, the tegmina also are more convex. 



STILPNOBLATTA MINUTISSIMA sp. n. 



$. Dark castaneous, nitid, minutely and obscurely punctate. Eyes 

 and antennal sockets equally far apart. Antenna? castaneous at base, 

 fuscous in the middle, apical 3 joints testaceous. Pronotum not 

 covering vertex of head. Tegmina squamiform, broader than long, 

 scarcely exceeding the mesonotum, punctate, radial vein represented 

 by an obtuse carina. Supra-anal lamina produced, rotundate, apex 

 not emarginate, exceeded by the sub-genital lamina which is semi- 

 orbicular, ample. Cerci very short and blunt, their jointing obscured.
