132 GEO. n. HORN, M. D. 



TAC'IIYS, Zieg. 



The following synonyms have been observed : 



T. oopterus Chaud. is vcntricosus Lee. — Type from Chaudoir. 



T. rivularis Mann, is nanus Gyll. — Type from Mannerheim. 



T. occnitus Lee. is (/ranarius Dej. — Type from Chaudoir. 



Dysmafhcs Saldhergi Mann. A specimen of Amphizoa inaohns Lee., 

 was sent by me to IMaklin for comparison with Dysmathes, and by letter 

 from M. Salle learn that they have been pronounced identical, as I 

 had suspected and have already published. 



Tanijrhinits ningidaris Mann. This insect has also caused trouble 

 since the day of its publication. Mannerheim placed it near Rhlnosi- 

 vius, etc., notwithstanding its pentamerous tarsi. An admirable figure 

 kindly sent by Miiklin seems to show that it is a Staphylinide ! of the 

 Omalium group and Dr. Leconte suspects may be allied to Tn'jono- 

 demus Lee. 



ENDOMYCIIID.E. 



In a small pamphlet entitled " Endoraycici Recitati " published in 

 London, (bearing date May, 1873, but not issued until September, 

 1873), by llev. Mr. Gorham, the following North American species are 

 described. 



Rhi/mhus minntus Gorham, 1. c, p. 56, is Alexia minor Crotch, 

 Trans. Am. Ent. Soc, May, 1873. The species is certainly a Rhi/m- 

 biis and not an Alexia^ and both minor and Llkei Crotch, must be 

 placed under the former generic name. 



Aphorisfa Jttoiieralis Gorham, loc. cit. p. 45, is a perfect reproduc- 

 tion of the type of Mijcetina morosa Lee. For this species as well 

 as fsefa Lee, Mr. Gorham has erected a new genus as above indicated, 

 the characters of which seem entirely too trivial to be considered 

 valid. 



SCAPHIDTID.E. 

 SCAPHIDIUM, 01. 



The four species indicated in our lists appear to be merely varieties 

 of one, and are separable as varieties in the following manner : 



Elytra with two red spots on each. 



Elytra with three short rows of large punctures qnadrigiittaf mil. 



Elytra with two short rows of large punctures quadripunctatum. 



Elytra without rows of junctures obliteratum. 



Elytr.a black without spots piceittn. 



Varieties of the latter form also occur parallel with those of the 

 spotted form and should these differences be considered valid two 

 more species must be indicated I prefer to consider all as variations 

 of one form.
