through its synonym rhino, & Gyllenhal, we obtain the genus 

 Magdalis of the Curculionidae. 

 Alagdalis is fully discussed below. 



Family CURCULIONIDAE. 

 Subfamily Magdalininae. 



Ithininae Pierce, 1916, Proc. U. S. N. M., vol. 51, Xo. 2159, p. 465. 



As noted under Rhina the writer was in error in above quoted 

 work. 



Genus Magdalis Germar, 1817. 



Magdalis Germar, 1817, Mag. der Ent., vol. 2, p. 339; type (atcrima Fab- 

 ricius) == armigera Geoffrey, designated by Leach, 1819, and 1824. 



Rhinodes Dejean, 1821, Cat. Col., p. 98; type cerasi (Fabricius) Linnaeus, 

 hereby designated. 



Thawin>i>hilus Schonherr, 1826, Cure. Disp. Meth., p. 52 (not Vieillnt, 

 1816); type violaceus (auct.) Linnaeus, by original designation. 



Mn(/diilii:t<x Schonherr, 1843, Gen. et. Sp. Cure., vol. 7, pt. 2, p. 135, pro- 

 posed for Thamnophilus; hence with violaceus as type. 



Rhino Pierce, 1916, Proc. U. S. N. M., vol. 51, No. 2159, p. 465 (not La- 

 treille, 1802); typcbarbicornis Latreille (1804 not 1802). 



Schonherr as first reviser divided the genus into two sub- 

 genera Thamnophilus and Panus and the first subgenus into two 

 stirpes Thamnophilus and Edo. 



Stephens (1829) subdivided into three genera Magdalis, Rhin- 

 odes and Panus. The following subdivision? agrees with Stephens. 



Now for the first time is it possible to correlate the European 

 and American classification in one system which will render 

 identifications easier.
