^ Genus Pboctaekelabeis, Lefebvre (restricted). 



(Bubo, part., Hatnbur, Hag^ 



Wings rather broad ; auterior pair with a small concave excision 



at the extreme base of the inner margin, followed by a slight 



dilatation, but not appendiculate : network open ; branch of 



the lower cubitus in the posterior wing confluent with the 



postcosta. 

 Antennas rather shorter than the anterior wings, strong, nearly 



straiglit, the base furnished with vcrticillate hairs ; club short 



and capitate ; a dense tuft of hairs on the face and between tlio 



antenna). 

 Ulyes with the divisions equal. 



Thorax robust, densely villose, especially on the breast. 

 Abdomen slender in the ^ , and furnished with long and slender, 



forcipate, simple, terminal appendices ; shorter and very obese 



in the $ . 

 Legs with the posterior tibiae nearly equalling the first two tarsal 



joints.

This is the species that has been universally mistaken for the 

 true capensis of Fabricius. I adopt Burmeister's name, though 

 it is hardly applicable, as the antenna? are scarcely "annulate." 

 It is, I think, also certainly Thunberg's capensis; his name is 

 independent of that of Fabricius. It appears to be a common 

 South-African species, and varies much in size and otherwise. 

 The following conditions are known to me : —
