I have but little doubt that tbis is the male of 6er- 

 staecker's species. The typical carina ending in a spatulate 

 tooth is a very characteristic feature of the Oriental genera 

 Perispliaeria and Pseadoglomeris and the male of oniscina is also in 

 general appearance very like males of Pseudoglomeris species from 

 Burma , Borneo , Java etc. The female of oniscina differs from 

 females of Oriental species of Perisphaeria and Pseudoglomeris in 

 the total absence of a tooth to the pronotal carinae beneath, 

 but otherwise is very similar ; it is convex and possesses the 

 power of rolling itself up into a ball like a Millipede or ter- 

 restrial Isopod and like the Oriental Perisphaeriinae of the female 

 sex. On account of the division of the abdominal tergites into 

 two zones separated by a sulcus , oniscina falls into the genus 

 Pseudoglomeris and not into the genus Perisphaeria. The genus is 

 new to the Ethiopian fauna.
