Derocalymma bottegiana Sauss. 



Central or East Somaliland (1897). Two female specimens. 



I cannot distinguish D. analis Sauss. from D. bottegiana Sauss. 

 The former is merely referred to and included in the synoptical 

 tahle, which is very difficult to follow. Mr. Peel's two examples 

 appear to agree entirely with the description of D. bottegiana 

 Sauss., which is described from Somali specimens. One of these 

 specimens still retains the yellowish velvet coat which is so easily 

 lost in handling. They are both a shade smaller than de Saussure's 

 types. 



Periplanetid.e. 



ElATTA ORIEVfALIS L. 



Somaliland (1895 or 1897). One female. 



PERIPLANETA AMERICANA (L.). 



Somaliland (1895 or 1897). One female.

 This genus is a link between Erunner's two sections of the 

 Orthoderidce. In the form of the pronotum it agrees with Cheetessei 

 Eurm., while the presence of small discoidal spines on the anterior 

 femora would place it in the second division. The conical and 

 pedunculated eyes, the spines of the anterior tibiae, the discoidal 

 .spines, the somewhat long anal membrane of the elytra separate it 

 from Chcetessa Burm. ; the form of the pronotum satisfactorily 

 divides it from the Eremiaphilce, Humbertiell-ce, and Chiropachce. 



In general appearance and coloration it resembles Chiropacka 

 and Tarachodes, but it differs in the depressed head.
