 Verb. Zool.-bot. Ges. Wien. XIII. 826. 1863. 

 Brachycaiiipta, Winnertz, ibidem. 833. 1863. 



Lateral ocelli contiguous to tbe eye margin, the middle one 

 very minute, in a groove, or wanting. Scutellum large, with 

 2 to 8 marginal setae. Legs slender, hind coxae with i to 3 

 posterior basal setae. Costa ends at the tip of Rs; subcosta 

 short, ending free or in Ri; petiole of media short; cubitus 

 forks proximad of the fork of the media, and often even 

 proximad of the base of the petiole of the media; first anal 

 delicate, short, incomplete (Allodia Winnertz) or eniirely want- 

 ing (Bracliycanipta Winnertz), second anal delicate and in- 

 complete. 



As both the structure of the anal vein and the position of 

 the fork of the cubitus are slightly variable even within a 

 species these characters cannot be used to distinguish the two 

 Winnertzian genera.
