African region, and, jiul<^iiig from the many new species met 

 M-itli in the collections 1 have had access to, there must be a 

 large number of species still to be described. The only 

 other Region with species of this genus is tlie Palsearctic. 

 I have not been very successful in identifying Loew's species, 

 but little of the material is from the Cape, whence most of 

 his species came — they are inserted in the table after the 

 descriptions, \\hicii may afford some help in their identifica- 

 tion in tiie future. 



The Walker types belonging to this genus are the fol- 

 lowing : — 



D. ubuntius, D. aphellus, D. atnazenes, D. isse, D. noas, 

 and D. mivatus (whicii latter is placed wrongly in Apoclea in 

 Kertesz's Cat.), D. phoeax. and D. ladon. 



D. phoeax is the only one I have been able to identify — it 

 appears to be the same as Dijsmachus auriburbis, Macq. 



All the others are in such a dirty and imperfect condition 

 it is impossible to identify them in any way — it would be 

 advisable to delete them from the list of specimens in this 

 genus. 



D. liiclon, type, appears to be lost, it is not in the Brit. 

 Mus. Coll. 



The species in the following table marked with a * are 

 all known to me and represented in tiie Brit. ]\Ius. Coll.
