pubescence round the head and thorax is white, but black on the 

 dorsal part, and the erect hairs on the elytra are interspersed with 

 appressed white squamose ones as thick as in P. pistrinaria, but not 

 quite so closely set ; the rest is as in P. capicola, and in well- 

 preserved examples the prothorax has also two small discoidal scaly 

 patches, and occasionally some scales along the anterior margin ; in 

 some females the pubescence is yellowish instead of being white. 



Length 7i-8 mm. ; width 4-4t mm. 



Hah. Cape Colony (Willowmore, Port Elizabeth, Graham's 

 Town, Knysna). 



Peritrichia puberula, n. spec. 



Black, with the elytra hght fulvous and the suture and the outer 

 margins slightly infuscate ; they have a marginal band of not closely 

 set greyish-white scales ; the shape of the clypeus, the colour and 

 disposition of the villose hairs covei'ing the upper and outer side in 

 both sexes is similar to those of P. capicola, and it has also two 

 discoidal small hairy spots ; it is very much smaller, the elytra 

 are more acuminate in proportion to the size, and the pygidial area 

 and the abdomen are distinctly scaly in both sexes. 



Length 6 mm. ; width 3^ mm. 



Hah. Cape Colony (neighbourhood of Cape Town). 



Peritrichia pygidialis, n. spec. 



Black, with the elytra light testaceous and very broadly infuscate 

 laterally ; clypeus sharply acuminate and refiexed ; head and 

 prothorax clothed with very long villose hairs, which in the male 

 are white along the apical margin of the prothorax and on the 

 sides, but are mixed with greyish-black ones in the discoidal part, 

 and have also there a transverse median band of white hairs, in 

 the female these hairs are flavescent, there are no scales, nor are 

 there any on the elytra which are strongly attenuate laterally 

 towards the apex, they are clothed with whitish or slightly 

 flavescent hairs, and have on each side at tip a small outer hairy 

 white patch ; the propygidiura and pygidium are clothed with black 

 hairs, and in the central part there is in both sexes a broad white 

 band consisting of lanuginose sub-squamose appressed ones ; the 

 prosternum and mesosternum are clothed with dense, villose, yellow 

 hairs in both sexes, and the metasternum with white ones ; the 

 abdominal segments have a fringe of squamose white hairs, but the 

 two apical segments and the upper side of the others have orange- 

 yellow villose hairs in both sexes ; claw of hind legs single, simple.
