 but differing in having a blunt pronotal horn, the sides of the thorax smooth and the posterior process 

 short, never reaching the apex of the tegmina and usually not extending as far as the end of the 

 abdomen. The head is subquadrate and roughly sculptured with the ocelh equidistant from each
