 Distribution. — (See fig. 4.)

 alutaceous, not smooth and shining. Foretibia not greatly differing 

 between the sexes; tibial margin of both with four broad teeth, the 

 margin serrate basallj^, but smooth between the teeth. This species 

 may be distinguished from the following species, subtropicus, new 

 species, by the shape of the carina on the vertex of the female.
