This genus contains several species which are very difficult to 

 determine, they being so closely related, that it is almost impossible 

 to separate them by distinct points of structure. This remark may 

 be applied to the males, but it is still more applicable to the females ; 

 some of which, as E. Dcsvoidy pointed out in his remarks on his genus 

 3fydina, are so different both in form and colour from those of the 

 opposite sex, that it is very difficult to know to what species they 

 belong, unless the two sexes are found together. On this account, it 

 is not easy to draw up a correct list of species ; I have, however, care- 

 fully examined all the specimens I have seen, and if I have erred, I 

 believe it will be on the side of making too few rather than too many 

 8])ecies. 



S. MACULOSA, Meig. 



S. NOTATA, Fall. 

 These two species bear a great resemblance to each other, and are often mixed 

 together in collections ; but they may be distinguished from each other by the 

 following differences of character. The former is generally rather larger and moi*e 

 elongated in shape than the latter ; the arista is shorter haired in S. maculosa than 

 in S. notata, though it is not very long haired in either species ; the scutellum has 

 a black spot on either side in S. maculosa, but only one central black mark at the
