It will be noted that the genitalia of D. caffra, as figured by 

 Zacher, are practically identical with those of D. bettoni Kirby 

 figured here. This may mean, either that the latter is merely the 

 macrolabious form of D. caffra, or that Zacher's identification is 

 incorrect. 



My figure of D. wigginsi Burr shows a metaparamere so like 

 that figured under the name of Picrania liturata by Zacher that 

 I expect here, too, there is identity (PI. VI. fig. 1).

Genus Acnodes Burr. 



The type of this genus, A. wetlmanni Burr, from Portuguese 

 West Africa, has typically Ethiopian parameres, and the total 

 apterousness is the only character which separates it from Dicrana 

 Burr (PI. VII fig. 8). ' 



The apterous American species, A. americana Burr, which has 

 so strong a superficial resemblance to A. wellmanni, will probably 

 require to be removed to another, and perhaps new, genus when 

 the genitalia are examined.
