THEMISTO BREVISPINOSA. 



In addition to the species included in this Appendix, 

 I may refer to some which have been described in recent 

 periodical publications, from the observations of Mr. 

 Spence Bate, Mr, William Thompson of Weymotith, 

 and others. I have not transferred these descriptions to 

 this work, partly because 1 am not in all cases quite 

 satisfied with the grounds on which the species have 

 been considered as distinct, and because they may be 

 readily examined in their original place of publication. 

 At the same time I am anxious to express my gratifica- 

 tion at this accession of young intelligent naturalists in 

 this field of observation, from whose active and continued 

 labours the most valuable results may be anticipated.
