This soldier was not collected with the winged adult but was 

 found at the same locality in July. It is close to grandis (pi. 4 

 fig. 23) ,^^ but has a larger pronotum, the marginal teeth on the 

 mandibles are differently placed, and the thoracic spines are longer. 



S. magnoculus Snyder is darker colored than dims, and has a 

 larger eye than either dirus or grandis.

 of southern Brazil.
