 pale also, the remainder blackish, occasionally the whole antennae 

 brownish yellow. Frons nearly one-third of the head in $ , black- 

 ish grey with rather thick bright yellow hair ; face dark grey with

 distinctly longer than the rest of the tarsus, whole tarsus a little 

 longer than tibia. Hind tarsus in 9 of the same proportion as in 

 the & except being less thickened.
