 to seven bears six small spines, on posterior margin. Each pleural 

 plate bears three or four brown posteriorly directed spines. Also 

 each dorsal plate bears three or four spines laterally just above 

 spines on pleural plates. Dorsum of first abdominal segment weakly 

 striate. Posterior edge of ninth segment bears a circlet of 10 spines 

 of which the dorsal six are long, brown, and prominent. Tenth
