 CoUection of the Deutschen Entomologischen Museum

(Fige. 1—6.) 



The f olloTvang notes and descriptions were made from material 

 forming a portion of a series of African Orthoptera loaned to me 

 for study by the Deutschen Entomologischen Museum, through 

 Dr. S. Schenkung. The remaining groups are in large part studied 

 and will be reported upon in the near future. 



The author wishes to thank Dr. Schenkung and the autho- 

 rities of the Museum for their kindness in permitting him to study 

 the collection. 



Mantidae. 

 Amorphoscelinae. 

 Amorphoscelis Stäl. 

 Amorphoscelis laxeretis var. cameronensis Werner. 



1908. Amorphoscelis laxeretis var. cameronensis Werner, Be-

Cameroon.] 



Cameroon. (Conradt.) One male. 



This specimen is defective, lacking the apex of the abdomen, 

 but in all probability it is a male. We have followed Werner in

 be found to merit specific Separation from the Togo laxeretis. 



Amorphoscelis grisea Bolivar. 



1908. Amorphoscelis grisea Bolivar. Deutsch. Entom. Zeit- 

 schrift, 1908, p. 515. [Cameroon.] 

 Cameroon. (Conradt.) One male. 

 This specimen is slightly smaller than Bolivar's measure- 



ments of the type, but otherwise it is in accord with his description. 



Orthoderinae. 

 Humbertiella Saussure. 

 Humbertiella africana n. sp. 



Type: $; Cameroon, West Africa. (Conradt.) [Deutsches 

 Entom. Mus.] 



This species is a true Humbertiella, a genus previously known 

 only from the Indian and Malayan regions. It is in fact very close 

 to H. indica Saussure, the type of the genus, differing only in its
