The species is closely allied to insignis ; but may be distinguished 

 by the more irregular disposition of the marginal spines, by the larger 

 number and greater diffusion of the spines on the fi'ontal area, and by 

 the presence of small spines on the median area of the thorax. Tlie 

 marginal spines are markedly smaller than those of insignis, and are 

 arranged in groups of three (instead of four or five) on the abdominal 

 segments.
