GENUS FIGITES. 159 



(1) Homorus, Foerster, which agrees with Pycno- 

 trichia in the absence of the mesosternal keel, but 

 differs from it in having the middle joints of the 

 flagellum not longer than broad, the third joint in the 



c? strongly incised, while the second abdominal seg- 

 ment is not hairy ; and 



(2) Tryschiza, Foerster, which agrees in most points, 

 e. g. in having the thorax smooth, shining, the eyes 

 bare, and the third joint of the antennae in straight, 

 but has an open radial cellule. The type is Figites 

 agaricolarum, Dbm., and the type of Homorus is Figites 

 abnormis, Giraud and Reinhard. 



Genus FIGITES. 



Figites, Latr., H. I., xiii, 210 ; Gen. Crust., iv, 19 ; Giraud, 



Yerh. z.-b. Ges. Wien, x, 147. 

 Psilogaster, Htg., Germ. Zeit., ii, 187 (pt.). 



Pronotum with a semi-vertical slope in front. Frontal sutures dis- 

 tinct ; eyes hairy; cheeks margined. Mesopleura separated from the 

 sternum by a keel. Parapsidal furrows distinct. Scutellum rounded, 

 rugose, with two fovese at the base. Antennae in $ short, thick, the 

 joints globose or moniliform, thickened towards the apex ; in <$ the 

 third joint is excised. Radial cellule closed; cubitus and areolet 

 obsolete ; the margin is sometimes fringed. Petiole raised, short, 

 thick, canaliculated. Thorax shining. Abdomen short ; the base strio- 

 late, slightly compressed laterally. Head more or less rugose. 



A genus well known by the keel on the mesopleuraB. 

 The species are common and of wide distribution, and 

 are parasites on Diptera.
