uox'mally also pubescent ; metaiiotum mainly concealed, with bare 

 sides. Abdomen oblong, narrower than thorax and barely double 

 as long ; male genitalia prominent, in $ the tip ol: tlie abdomen 

 pointed. Ler/s with front pair, and especially front tarsi, longer 

 and thinner tlian in Leptis ; front tibicB shorter than, middle pair 

 equal to, and hind tibiae rather longer than, the corresponding 

 tarsi ; front coxae ratlier long ; front tibiae unspurred ; middle 

 tibiae with two spurs, of which the front one is considerably the

 1st and 2ud longitudinal veins ending at or a little beyond middle; 

 2nd starting well before the discal cell ; 3rd beginning opposite 

 base of discal cell, forked at a more or less acute angle rather 

 soon after quitting anterior cross-vein, the branches gradually 

 diverging and embracing the wing-tip ; discal cell elongate ; upper 

 branch of 4th lougitudiual vein forked at tip of discal cell ; lower 

 branch simple ; posterior cross-vein proximad of anterior cross- 

 vein ; 5th vein forked just before posterior cross-vein, the branches 

 separating widely, lower branch always curved downwards, meeting 

 6th vein at or just before wing-border, closing anal cell. 



Range. Europe, India. 



Life-history unknown. 



The genus Atrichops was unfortunately wholly overlooked by 

 rae in describing the species herein i-eferred to it, which were 

 placed in Atherix at the time of description. Atricliojis is quite 

 well founded, the species having the cheeks distinctly bare. Set 

 up by Verrall for Atherix crassi2^es, Mg., a European species, I 

 know of no others belonging to it except those I have myself 

 recorded from the East.
