obtuse angle and the posterior is nearer the base of the wing 
than the mid ; the sub-costal joins the costa at about half the 
length of the wing. 
This genus is founded on some specimens brought back by 
Dr. Durham from Brazil, unfortunately all females. It is 
closely related to Sabethes, Wyeomyia and Trichoprosopon . 
From the two former it can be separated by the presence of 
scales on the metanotum, from Trichoprosopon by the absence of 
bristles on the clypeus, and on the basal lobe of antennae, by 
the position of the cross-veins and by the shortness of the palpi. 
No £’s have been found. 
The genus comes in Section C, page 98, Yol. I., on account 
of the scaly metanotum, even if the £ palpi are short. 
It is a sylvan species. Nothing is known of its life history.
