GENOTYPE, Spogostylum, mystaceum, Macq. 



$ . Generic characters of Anthrax. Pace not prominent, with 

 rather short hairs: frons tomentose ; 3rd antennal joint short, 

 tip rounded, style of two distinct segments, cylindrical ; 1st joint 

 as long as 3rd, 2nd rather shorter, with a few hairs at tip. 

 Wings three times as long as abdomen ; three submargiual cells, 

 1st and 2nd cells with an appendix. 



Range. North Africa, Asia Minor, India, Chile. 



Macquart specially notes the " moustache " covering the face, 

 the antennal style, the shortness of the abdomen, and the length 

 of the wings. The genus is allied to Exoprosopa by the three 

 submarginal cells and to Aryyramcela by the antennal style, the 

 shortened abdomen, and the long wing.
