23. Allodia Winnertz. 

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

 Brachycampta, Winnertz, ibidem. 833. 1863. 



Lateral ocelli contiguous to the eye margin, the middle one 

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

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

 posterior basal sets. 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 entirely want- 

 ing (Brachycampta 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. 



Table of species. 

 a. Hind cox£e each with a vertical black dash near the apex on outer 

 side ; under side of hind femora each with a brown mark ; 6 

 scutellar setse. i. crassicornis and varieties, 



aa. Not so marked. 



b. Fore metatarsus equal or longer than the tibia and at least 1-4

 nearly twice as long as the fore coxa. 2. bulbosa n. sp.
