The following description of Saxitius, translated 
author, differs somewhat from the preceding one: — 
Head and prothorax equally long, the former 
cylindrical; post-ocular part slightly tapering 
hindward, a little longer than the ante- 
ocular part, which is hardly lower than the 
seat of the ocelli, the latter being very 
slightly raised. First joint of the rostrum 
short, just shorter than the ante-ocular part 
of the head; second about twice as long as 
the first. Antennae rather short ; first joint 
a little longer than the head. Lobes of the 
prothorax with small spines or acute
