S2 SJÖSTEDTS KTLIMANDJARO-MERU EXPEDITION. 17: '2. 



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

 sutura] margins failing to meet by half the breadth of tlie tegnien. Wings absent. 

 Abdomen piceous above, 7*'^ tergite slightly prodnced, its posterior margin simiate. 

 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; j^i^lvilli minute, apical. 



$. Resembles cT but piceous instead of castaneous. Tegmina relatively shorter 

 and narrower, sub-triaiigular in shape. Seventh abdominal tergite, more produced ; 

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



c^. Total length 15 mm,; tegmina 3 mm. x 2,9 mm.; pronotum 5 mm. x 6,i mm.

The species closejy resembles BlaUa flavilatera Sauss. but can at onee be 

 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 \^^ abdominal 

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

 the genus Blatta to the genus Stylopyya Fiscii. Bhitta 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.

 Lower Meru (November); 1 $. 



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 tliat 

 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 difficulty and 

 I believe 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. S. spinulijera Krauss. San Thome, W. Africa. 



5. S. hoUentota Sauss. E. Africa. 



6. S. brancsiki n. n. (= S. anthracina Brancs.) Zambesi. 



7. S. senecta Rehn. Zululand. 



8. .V. tetra Wlk. Natal.
