Siosta Wlk. 



The genus was created by Walker, vii., p. 1G88, for Latreille's 6i/«.sciirtta, without 

 apparently Walker's observing that it was the same insect which at vol. ii., p. 384, 

 he had described as Saagala gloriosa. I retain the name Siosta, as he expressly 

 states that the antennae of the S are subserrate.
