short longitudinal keels. Mesonotum smooth, thickly covered with 

 long fuscous hair, distinctly trilobate ; scutellum sparsely covered 

 with longish fuscous hair ; opposite the post-scutellum is a large 

 broad yellow mark. Median segment elongate, the base behind the 

 transverse keel smooth, the rest transversely striated, but not strongly 

 or closely, the yellow marks commence near the keel, the broad 

 part shortly behind the middle and extending right across the apex. 

 The middle of the propleurse finely longitudinally striated ; the 

 meso- above similarly striated, the striae extending to shortly beyond 

 the middle ; the apex on the lower-side is more closely and finely 

 striated ; the meta- more strongly, closely obliquely striated and 

 thickly covered with long white hair. Abdomen smooth, long and 

 narrow. 



Comes near to F. frontella\ may be known from by 

 the keels or striae on the front being curved or transverse, 

 not longitudinal, by the pleurai not being so strongly or 

 closely striated, and by the apex of the yellow line on the 

 metanotum being much more largely dilated.
