A species closely allied to the Lamia vittator, Fabr. Syst. 

 Eleuth. ii. 297. 76, and figured by Olivier, 1. 15. f. 104 : the body 

 in the new species is longer, and the elytra are aculeated at the 

 end. The spines on the thorax are not so thick as in the Fabri- 

 cian species, and the three black bands on the thorax are not so 

 strongly marked ; the head is differently marked ; the present 

 species wants the wide black band, with a white spot in it on 

 the vertex behind each eye ; the abdomen has three or four ochrey 

 band-like spots on each side.
