The collections of insects of other orders made during our excur- 

 sion have not yet been sufficiently worked out to allow us to give an 

 account of their contents. A considerable number of Neuroptera and 

 Orthoptera have, however, been collected ; Hymeuoptera, Diptera, 

 and Hemiptera, have also not been neglected, though of the latter 

 chiefly Hydrocorisae have been found. 



The Crustacea, crawfishes, and other small freshwater shrimps, 

 as well as the leeches and other worms, have also attracted our at- 

 tention, and some interesting species have been collected ; but the 

 difficulty of establishing their synonymy induces me to postpone the 

 publication of their description. l. a.
