ON THE STRUCTURE OF THE ANTENNAE. 583 



Krapelin says the great variety of special sensory structures 

 which have been described on the antennae, or sunk beneath 

 their surface, resolve themselves into ' organs of a single type, 

 a more or less developed, free, or deeply-seated seta, con- 

 nected by a wide pore canal with a multi-nucleated (?) ganglion 

 cell, which sends an axis cylinder into the seta.'

This paper gives a bibliography of fifty-nine papers, and the author 

 has reviewed the whole critically. As most of the papers recited are 

 rather of historical than scientific interest, all but the most important 

 have been omitted in the present list.
