Dr. Horn made a few remarks concerning several Coleoptera, regarding 

 whose identity there is some doubt. Concerning Dysmathes Sahlbergi Mann., 

 the vie%v was expressed that it was, without doubt, identical with Amphizoa in- 

 fiolens Lee, described but a few months anteriorly. Dysmathes was described 

 as a Tenebrionide, and Mannerheim distinctly states that tlie posterior tarsi 

 are 4-jointed, but with a knowledge of the fact that a similar mistake had al- 

 ready been made and corrected by the same author, it is hardly presuming too 

 much to infer that a mistake has also occurred here. (The error above alluded 

 to is that of re-describing Amphicyrla dentip>es as Encyphus hybosoroides and 

 ))Iaoing it among the Tenebrionidje.; Moreover the measurements are exactly 

 the same, so that with very little trouble a figure can be drawn. It was in this 

 manner that attention was drawn to the identity of the two insects. The Sin- 

 lennai o( Dysmathes are exactly those of >l?«^)A/soa, and do not at all resemble 

 those of any Ten(djrionide. 



The attention of the Society was also called to the Geotrupes of the United 

 States. Specimens in series were exhibite,d, demonstrating the correctness of 

 the views e.xpr&ssed in a paper presented at the preceding meeting, in which 

 tlie species recognized by Jekel were reduced to less than half the number. 

 The importance of large series of species of this and other genera was urged on 

 .all whfi have collections, as the only means of arriving at a knowledge as to 

 what c-oustitutos a species.
