476 BI.ATTIDAE OF SPANISH GUINEA (2) 



3, Theganopteryx fantastica sp. n. 



(^ . Pale llaA'o-testaceous. Head and antennae unicolorous; 

 eyes piceous, close together on the vertex of the head. Pronotuni 

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

 veins simple, posterior ulnar 5 I'^mose. Wings hyaline, costal 

 margin faintly suffused with fla\ous, mediastinal vein simple, 

 18 costals, the more proximal slightly incrassatc, medio-discal 

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

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

 cal triangle, l''' axillary 4-ramose. 



V abdominal tergite produced as a flat narrow process ex- 

 tending nearly to the apex of the abdomen slightly spatulate at 

 its apex, 8''' tergite with the posterior angles strongly produced; 

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

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

 tal lamina produced, asymmetrical, apex concavely emarginatc, 

 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 close together on vertex of head. Wings 

 uniformly suffused with pale flavid. 



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

 orbicular, ample. 



Total length ((j") 9 mm., (9) H; length of body i^) 8-1 mm., 

 (9) 9-6; length of tegmina ((^f ) / mm., (9) 9-5; pronotum (cf) 2- 

 9 X 3-2 mm., (9) 3 X 4-5- 



2 cfcf . This very remarkable species also occurs in Kame- 

 run (coll. Bolivar, 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 vertex of the head — an unusual feature in this 

 genus — should render the species easy to determine. 



4. Theganopteryx patricia Gersi. 



2 cf (5^. Differing from Kamcrun examples by the unicolor- 

 ous antennae.
