Scale of adult $ to 3 mm. in diameter, almost circular, ochreous fawn to straw- 

 colour, often paler towards the margin, semi-glassy and smooth, with a dark brown 

 to black blotch in the centre of the second exuviae. Exuviae central, flat. First 

 exuviae thin, pale, almost colourless and transparent. Second exuviae brown, bright 

 coloured, central, with a black blotch in centre. 



Puparium of <$ smaller, somewhat elongate, pale buff, semi-transparent, thin and 

 delicate, with exuviae slightly darker. 



The body of the adult $ resembles that of articulatus to some extent, but when under 

 a low power the following differences are noticeable : The sides of the articulation 

 are less acute and form a broad V. The anterior margin usually has a series of about 

 twenty rough chitinous tubercles. The finger-like process on the lateral margins 

 of the cephalothorax of articulatus is replaced by a process which is most often 

 irregularly forked at the extremity. Pygidium as illustrated (fig. 108).
