BLATTIDAE 



OF 



SPANISH GUINEA 



R. SHELFORD 



This small collection was entrusted to me for examination one 

 or two years ago by Sr. D. Ignacio Bolívar but I have only re- 

 cently liad an opportunity to examine it critically. As might have 

 been expected the majority oí the species are already known 

 írom Kamerun, from which district large collections of cock- 

 roaches have been sent to European museums and have been 

 studied by Gerstaecker, Borg and myself. 



Gen. Theganopteryx Brunner. 



1. Theganopteryx nítida Borg. 



I cf . Previously rccorded írom Kamerun. 



2. Theganopteryx lucida Br. 



I 9- A variety with the pronotum strongly marked with two 

 l'uscous vittae. 



I have examined the type of this species, now in the Stettin 

 Muscum; Brunner suggested Australia as the habitat of the 

 species but I' have found identical specimens in collections from 

 West África and believe that the type carne from Oíd Calabar 

 originally.
