there towards the apex, clothed with non-contiguous, squamiform sub- 

 flavescent appressed hairs, and having on each side five somewhat 

 broad, saffron-yellow scaly patches, the two lower of which coalesce ; 

 the apical part has a band of similar scales which ascend the posterior 

 part of the suture and coalesce sometimes with the inner, lower 

 dorsal patches ; in the female the bands of scales on the prothorax 

 are similar but narrower, and white, the patches on the elytra are 

 smaller and have a greater tendency to form two bands ; the propy- 

 gidium, which is very broad, the pygidium and the abdomen are 

 entirely clothed with scales saffron -yellow in the male, white in the 

 female ; the hind legs are not scaly and not very villose, and all of 

 them are piceous ; hind claws double. 



Length 6-7-i- mm. ; width 4-4^ mm. 



Hab. Damaraland. 



This species, of which I have seen only three examples, is easily 

 recognised by the arcuate scaly band on each side of the prothorax. 



Peritrichia dita, n. spec. 



Allied to P. ditissima, but smaller; the prothorax has arcuate 

 bands of scales in the discoidal part in the female only, the short 

 hairs covering it and also the scales forming the basal band are 

 white, and on the elytra, w4iich have a border of white scales, are 

 two transverse, non-interrupted bands of whitish scales ; pygidium 

 and abdomen scaly-white. 



Length 6 mm. ; width 3J-3|^ mm. 



Hab. Cape Colony (Carnarvon), Damaraland. 



Peritrichia plebeia, n. spec. 

 Black, with the anterior and intermediate legs rufescent ; clypeus 

 moderately acuminate obliquely and with the apical part dentate ; 

 head and prothorax clothed with long, but not very dense erect black 

 hairs, the latter part shows no trace of scales along the margins, but 

 there are two small median patches of flavescent scales in the male 

 only ; scutellum non-scaly ; elytra sub-parallel, not much longer than 

 broad, and with the humeral costa well defined, they are clothed 

 with very short, appressed black hairs, and in the male there are on 

 each side four indistinct maculae of flavescent scales, and a nearly 

 obliterated narrow, marginal apical band of similar ones ; propy- 

 gidium and pygidium scaleless in the male, but with a slight fringe 

 of them in the female ; abdomen without scales except on the two 

 basal segments in the male ; anterior tibiae bi-dentate in the male, 

 tri-dentate in the female ; hind claws single, simple.
