(Read September 28, 1904.) 



This paper is based on species collected for me by the Rev. J. A. 

 O'Neil at Dunbrody, at Pearston and Stellenbosch by Prof. Robert 

 Broom ; on species in the Collection of the Albany Museum, 

 Grahamstown, collected by Mrs. G. White, Mrs. Pringle, and 

 Misses Daly and Sole in the neighbourhood of Grahamstown, for the

 bi-dentate ; the sub-apical tooth small, the apical long and sharply 

 pointed. Mesosternum furrowed laterally on the basal half. Wings

 sparsely combed. First abdominal segment sessile ; becoming 

 gradually widened from the base to the apex ; longer than it is 

 wide in the middle ; the spiracles placed near the apical third. The 

 basal three segments are strongly closely longitudinally striated ;
