 Genotype, Suragina illucens, Walk. ; the original species. 



$ . "Body linear, moderately broad. Head almost as broad as 

 the thorax; vertex and front of eqnal breadth. Proboscis porrect, 

 compressed, a little shorter than the breadth of the head. Palpi 

 lanceolate, contiguous to the proboscis. Antennae very short ; 

 i3rd joiut round ; arista slender, bare, longer than the antenn*. 

 'Thorax a little narrower in front. Abdomen somewhat flat, less 

 than twice the length of tlie thorax, obtuse at the tip. Legs bare, 

 unarmed, rather long and slender. Wings moderately loug and 

 broad ; radial vein slightly curved ; forks of the cubital vein a 

 little longer than the preceding part; 3rd externo-medial vein 

 inclined beyond the discal areoiet towards the 4th, which is 

 straight ; subaual and anal veins united close to the border ; 

 discal areoiet nearly six times longer than broad, its fore side 

 hardly angular." ( Walker.)

It is necessary to reproduce Walker's own description of this 

 genus unaltered, since no example has been available for re- 

 descriptiou. 



Osten-Sacken drew attention t to the fact that, in setting up 

 Suragina, Walker omitted to note its close affinity to Atherix, 

 and observes that that author had labelled as a Suragina a species 

 which Osten-iSacken himself subsequently described as Atherix 

 limbata (loc. cit.). Tet Walker certainly knew oi Atherix, a, not 

 uncommon European, even British, genus. 



Karsch admits the great affinity between the two genera, but 

 seems to have successfully differentiated them. J 



Only three species are known.
