FLIES.

The present paper deals largely with insects of economic impor- 

 tance, here described in order to have names available for use in dis- 

 cussions of their host relations in economic papers. 



Family BRACONIDAE. 

 Genus BASSUS Fabrieius. 



As shown by Viereck in his " Type Species of the Genera of Ichneu- 

 mon-flies/' 1 the genus Microdus Nees 2 is isogenotypic with Bassus 

 Fabrieius, 3 while the Bassus of authors is Anomalon Jurine 4 and 

 Anomalon of authors is Paranemalon Viereck. 5 He also reduced 

 Diplazon (Nees) Gravenhorst 6 to synonymy with Anomalon Jurine 

 on the ground that it is isogenotypic with that genus. He, however, 

 overlooked the fact that Panzer 7 had used the name Anomalon for 

 his cruentatus two years before it was proposed by Jurine. A. 

 cruentatus is unrecognisable. 



Viereck's genotype list should, therefore, be amended to read as 

 follows : 



(Anomalon Authors) = Paranomalon Viereck. 



(Anomalon Jurine) — Diplazon (Nees) Gravenhorst. 



Anomalon Panzer. 



Fauna Ins. German., 1805, Heft 94, pi. 15. 



Type. — Anomalon cruentatus Panzer. (Monobasic.) 



(Bassus Authors) = Diplazon (Nees) Gravenhorst. 



Diplazon (Nees) Gravenhorst ( = Anomalon Jurine, preoccupied). 



The species described below is a representative of the genus Bassus 

 in its true sense.
