APPENDIX. 



This appendix contains modifications and additions, and treats with 

 the new species the diagnoses of which I received too late to insert in 

 the first part of the work. 



The numbers within brackets indicate the sequence in the keys of the 

 handbook, but only approximately for the new species (marked a, 6, etc.).
