 which it becomes very indistinct ; wing-ribs tawny; veins black,

 Sponijostyhoii, Kertesz, Cat. Dipt, v, p. -"i'S (1909). 



Genotype, Sjwgosfi/lum mi/staceum , Macq. 



2 . Generic characters of Anthrax. Face not prominent, \Aith 

 rather short hairs: frons tomentose : ord antennal joint shoi't, 

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

 as long as c5rd, 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. 



Maccpiart specially notes the " moustache " covering the face, 

 the antt^nnnl style, the shortness of the abdomen, and the length 

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

 submargiual ceils and to Argi/rammha hj the antennal style, the 

 shortened abdomen, and the long wing.

 former at level of anteunfc rather less than one-third the width of 

 the head, diminishing to two-thirds of that width at vertex ; black
