32 SJÖSTEDTS KILIMANDJABO-MEBU EXPEDITION. 17: 2. 



margin. Tegmina nearly as broad as long, extending to middle of metanotum, their 

 sutural margins failing to meet by half the breadtli of the tegmen. Wings absent. 

 Abdomen piceous above, 7*^ tergite slightly produced, its posterior margin sinuate, 

 supra-anal lamina subquadrate, its posterior margin notched; abdomen beneath castan- 

 eous at base, piceous at apex, sub-genital lamina broad, extending a little beyond 

 the supra-anal lamina, with two symmetrically disposed styles. Cerci piceous, acu- 

 minate. Legs rufous; pulvilli minute, apical. 



?. Resembles <^ but piceous instead of castaneous. Tegmina relatively shorter 

 and narrower, sub-triangular in shape. Seventh abdominal tergite, more produced: 

 supra-anal lamina produced, cucullate, apex broadly emarginate. Legs darker. 



cT. Total lengtli 15 mm.; tegmina 3 mm. X 2,9 mm.; pronotum 5 mm. x 6,i mm.

The species closely resembles Blatta flavilafera Sauss. but can at once bc 

 distinguished by the very reduced tegmina. The variety castanea Adel, is probably 

 a distinct species, the male has a prominent scent-gland opening on the 1^*^ abdominal 

 tergite as in the genus Pseudoderopeltis Krauss. B. propinqua affords a passage from 

 the genus Blaüa to the genus Stylopyya Fiscir. Blatta at present may be reserved 

 for those species in which the tegmina are not squamiform in both sexes and Slylo- 

 pyga for those species with the tegmina squamiform or absent in both sexes but the 

 discovery of a few more species like propinqua would cause this generic distinction 

 to break down.

The species was previously recorded from East Africa e coli. Voeltzkow. The 

 specimen before me differs slightly from de Saussure's description but I believe that 

 it must be referred to that species. There are eight species of Stylopyga occurring 

 in Africa which can only be distinguished from one another with great difficujty and 

 I beUeve that some of the species can be sunk as synonymous with others. The 

 species are: 



1. S. aethiopica Sauss. Gaboon. 



2. S. manca Gerst. Cameroons. 



3. S. anthracina Gerst. Cameroons. 



4. 8. spimdifera Krauss. iSan Thome, W. Africa. 



5. S. hottentota Sauss. E. Africa. 



6. S. bmncsiki n. n. (= *S'. anthracina Brancs.) Zambesi. 



7. *S'. senecta Rehn. Zululand. 



8. S. tetra Wlk. Natal.
