but since that work was written several additional instances 

 of their occurrence had been made known, showing that these 

 organs were less uniform in structure and even more wonder- 

 fully diversified in position than Darwin considered them to 

 be; while their discovery in the larvae of certain forms would 

 lead to some modification of the view that they have originated 

 in connexion with sex and primarily serve the purpose of 

 attracting the sexes to one another. He gave a detailed 

 account of their pi-esence on the head, prothorax, mesothorax, 

 legs, abdomen and elytra, enumerating several genera of 

 Tenebrionidiv, Endomychidse, Hisjndse, etc.^ in which they had 

 not previously been known to occur, and describing those of 

 certain Hisjndse, as being the most complex in structure. He 

 mentioned additional instances in which they occur in one sex 

 only, or differ according to sex, and pointed out that, contrary 

 to Landois' opinion, they are frequently present in both sexes 

 of Curculionidoe, but in several species the striated area occu- 

 pies a different position in each sex, being found on the elytra 

 in the males and on the last dorsal segment in the females.
