Genus Bormansia Verh. 



This genus agrees generally with the preceding, which it re- 

 places in Eastern Africa, but it may be distinguished at once by 

 the entire absence of any rudiments of elytra, and the consequently 

 differently constructed pronotum. Of the four known species, 

 B. oricntalis Bor. and B. meridionalis Burr have not yet been 

 examined in this respect, but the two original species of Verhoeff's 

 can be separated, according to the figures give by Zacher, pre- 

 sumably from Verhoeff's originals ; the features given by Verhoeff 

 are certainly scarcely sufficient to justify the separation of these 

 two species. 



I have not had the opportunity of examining the genitalia of 

 this genus, but Zacher figures and describes it ; the virga appears 

 to be complex.

Sub-family 4. PygidicraniN/E. 



The old comprehensive genus Pygidicrana of Serville was first 

 sub-divided in 1908, when I erected four new genera, based chiefly 

 upon the form of the pronotum and of the ninth sternite of the 

 male. 



In 1911 a further arrangement was proposed by Zacher, based 

 on certain new characters, the chief being the genital armature. 

 This arrangement was admittedly provisional only, as the author 

 had but meagre material at his disposal. 



I have been able to examine, and here figure, the genitalia of 

 a number of additional species, which involves a recasting of both 

 existing systems. I find a considerable diversity of form in the 

 male genitalia, which I am prepared to admit offer better generic 

 characters than the width of the pronotum and ninth male sternite, 

 formerly employed by me, and it is necessary to modify the 

 arrangement and definition of the genera, which fall into fairly 

 well-defined geographical groups, much better indeed than they 

 did under the old arrangement. As a specific instance let us take 

 the genus Pyge Burr, the type of which is the Oriental P. modesta 

 Borm. The characteristic of this genus as defined originally is the
