ME. E. M'LACHLAN ON A SYSTEMATIC 



alae posticae $ nebula magna paullo ante apicem fusco-testaeea, 

 ornatae. 



Hab. Cape of Good Hope. In my collection and in Brit. Mus. 



Genus Peoctaeeelabeis, Lefebvre (restricted). 

 (Bubo, part., JRambur, Hag.) 

 Wings rather broad ; anterior 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. 



Antennce rather shorter than the anterior wings, strong, nearly 

 straight, the base furnished with verticillate hairs ; club short 

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

 antenna?. 



Eyes 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. 

 Hab. South Africa. 



Species. 



1 . P. annulicornis, Burmeister. (Ascal. annulicornis, Burnt. Handb. 



ii. p. 1001. — Myrmeleon capense, Thunbg. Nov. Act. Holm. — Ascal. 



dapensis, Burm. op. cit. p. 1002 (nec Fab.). — P. capensis, Lefebv. 



Guerin's Mag. 1842. —Bubo capensis, Ramb. Nevrop. p. 854. — Ascal. 



involvens, Walk. Cat. Brit. Mus. Neurop. p. 422(£).) 

 Hab. South Africa. 



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 antennae 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 : — 



1 . Alee fere vitreae, 6,2- 



2. Alae uniformiter pallide brunneo tinctae, S • 



3. Alaeposticae nebula magna ante apicem, fuliginosa, ornatae, 



2 (=involvens, Walker). 



4. Alae posticae fere uniformiter pallide fuliginoso-suffusae, ? .
