Explanation of Plates XIX-XXV. 



[All the figures of genitalia are magnified 50 diameters, the rest 

 13 diameters. Except in the case of S. crassicosta, all the figures 

 of genitalia have been prepared from specimens cleared in potash 

 and mounted in balsam ; it should be noted that owing to this treat- 

 ment the apical parts are more exserted and the male hypopygium 

 appears broader than in the dry specimens.]
