Eight specimens. A female from Peradeniya, taken in Decem¬ 
ber, 1902, “ from grass land two females from the same locality 
caught in February and March. One female from Pundalu-oya 
was “ swept from a grassy ravine ” in May ; while from the same 
locality three males were found “ among fallen leaves under shade 
of trees ” in May. Still another male was “ swept from grass 
fields ” in March from the same locality. 
This small apterous species is easily distinguished by the 
structure of the vertex and frontal costa. It is monotypic and 
appears to be confined to Ceylon.
