The form of the thorax is round-oval, the caput is rather 

 elongated, slightly prominent at the eyes, and the lateral 

 marginal constrictions are strong. 



The eyes of the two central pairs form a small quadrate figure 

 rather longer than broad, and those of each lateral pair are con- 

 tiguous to each other, and not very far removed from the central 

 four. 



The legs are neither very long nor strong ; the differ ence in 

 their length is not great, and the spines are very slender. 



The palpi are short, the digital joint and palpal organs of very 

 large size, and the latter very complex. 



The maxilla; are short, strong, bent strongly downwards, and 

 towards the labium, which is short and somewhat pointed at the 

 apex. 



The abdomen is produced behind into one or more somewhat 

 tuberculiform protuberances. 



One species only of this genus is at present known in Britain ; 

 it is found, but not abundantly, in various wooded parts 

 of Dorsetshire, as well as in other parts of Great Britain.
