234 MR. HARDY ON THE BERWICKSHIRE STAPHYLINIDJl. 



Synopsis, viz., Erichson's Genera et Species Stapliylinorum, 

 Gyllenhal's Insecta Suecica, Lacordaire's Paris Fauna, and 

 Heer's Fauna Coleoptera Helvetica ; or to a Monograph of the 

 Scottish species, now in course of preparation. Berwickshire 

 may be said to be rich in the members of this family, supply- 

 ing in some of the genera, more species than have hitherto 

 been recorded for all Scotland taken together. The propor- 

 tion in reference to the British Fauna, cannot be ascertained 

 without a revision of the entire order, which it is at present 

 impossible to effect, while the types of so many supposed 

 species are placed beyond the reach of an investigator in the 

 country. Judging, however, from several collections of Eng- 

 lish insects, submitted to my inspection by friends favourable 

 to these inquiries, the disproportion that will be found is 

 more apparent than real. I may have occasionally erred in 

 citing the synonymes of British authors. Those who are 

 aware how much perplexity exists in this particular, will 

 readily forgive mistakes, arising from imperfect descriptions.
