A number of ? specimens (No. 3890) from Knysua are also 

 remarkably close to H. nigra, but vary in a few details. In the 

 absence of <$ in any of the cases it is impossible to definitely name 

 the species from Caledoii or Knysna as H. nigra, but it is possible 

 that they may be. 



A number of ? specimens (No. 13842) from Stellenbosch strongly 

 resemble H. nigra, and are also apparently closely allied to it ; it is no 

 doubt a young example of this species which was described by Simon 

 as Damarchodes purcelli (Bull. Soc. Ent. Fr. 1903, No. 3, p. 43) ; the 

 description, however, is of a juvenile, and is based mainly on colour 

 and lacks specific details. 



Damarchot/es is considered by Purcell to be synonymous with 

 Hermacha ; Hewitt, however, thinks it allied to Pelmalorycter (Ann. 

 Durban Mus. vol. 1, pt. 3, p. 224). 



HERMACHA NIGRISPINOSUS, n. sp. (Text-fig. 7).
