 straight and parallel. 



Central Africa : Rugege Forest, at about 6000 feet, in 

 August; 2 cJ, 1 ? , 1 nymph {Schuhotz). 



This is a very remarkable species ; in appearance and 

 general structure it approaches very closely the West- African 

 forms Sp. rub)'a, Bor., also Sp. tuberculata, Bor., but is 

 sharplv distinguished by the strong, keen, and well-developed 

 keel of the elytra. The only members of the Labiidae hitherto 

 known with keeled elytra are the South American, very distinct, 

 genus Stroyigylopsalis, Burr, the aberrant Labia tenuipes, 

 Burr, also from South America, and the Oriental and Austra- 

 lian genus Nesogaster, Verb., none of which approaches the 

 species in question. In spite of its close structural resem- 

 blance to the other African forms quoted, the keel of the 

 elytra is so altogether distinctive and striking a feature that 

 a new genus, if not a new subfamily, must be erected for it 

 when this group is revised. 



It is interesting to note that the keel of the elytra is 

 distinctly visible on that organ when only partly developed 

 in the nymph stage.
