47^ BLATTIDAE OF SPANISH GUINEA (2) 



3. Theganopteryx fantástica sp. n. 



<$. Palé flavo-testaceous. Head and antennae unicolorous; 

 eyes piceous, cióse together on the vértex of the head. Pronotum 

 trapezoidal. Tegmina with 1 9 costáis, radial and anterior ulnar 

 veins simple, posterior ulnar 5 ramose. Wings hyaline, costal 

 margin faintly suffused with flavous, mediastinal vein simple, 

 18 costáis, the more proximal slightly incrassate, medio-discal 

 área nearly 4 times broader in the middle than the medio-ulnar 

 área, crossed by about 13 transverse venules, a prominent api- 

 cal triangle, I st axillary 4-ramose. 



I st abdominal tergite produced as a fíat narrow process ex- 

 tending nearly to the apex of the abdomen slightly spatulate at 

 its apex, S tu tergite with the posterior angles strongly produced; 

 supra-anal lamina quadrately produced, sub-lobiform, covering 

 the bases of the cerci which are situated cióse together. Sub-geni- 

 tal lamina produced, asymmetrical, apex concavely emarginate, 

 two minute styles. Femora moderately armed, front pair with 

 3 stout spines on the anterior margin beneath, succeeded dis- 

 tally by piliform setae. 



9- Similar, eyes less cióse together on vértex of head. Wings 

 uniformly suffused with palé flavid. 



Supra-anal lamina produced, trigonal; sub-genital lamina semi- 

 orbicular, ampie.

2 efe?. This very remarkable species also oceurs in Kame- 

 run (coll. Bolívar, Berlin Mus., types). The modification of the 

 secondary sexual apparatus of the male is quite without parallel 

 amongst the Blattidae and combined with the approximation of 

 the eyes on the vértex of the head — an unusual feature in this 

 genus — should render the species easy to determine. 



4. Theganopteryx patricia Gerst.
