206 Descriptive Catalogue [1896. 



three basal joints, which are smooth ; prothorax shghtly inflated in 

 the anterior part and truncate at the base ; elytra fused together, 

 always more or less transparent, subovate or oblongo-ovate, seldom 

 parallel, narrowly striate with the intervals plane, lateral margins 

 with a series of deep punctures interrupted in the median part ; the 

 tarsi of the male a little more setulose underneath than those of the 

 female, and the anal segment has one bristle on each side, and two 

 in the female. 



Owing to the transparency of the elytra, the teguments show more 

 or less through the wing cases ; it is therefore necessary to detach 

 them to be able to detect the deeper or lesser infuscate markings. 



The wingless insects included in this genus are found under stones 

 or decaying vegetation. They are crepuscular, if not nocturnal, and 

 have not been recorded outside the limits of South Africa.
