as types. 

 1817. Ib. in Cuv., Regne An. iii. 553: specifies only Alexis (not 



given in the original list), as a species found in the 



environs of Paris, but refers to previous works for the 



species. 

 1823. God., Encycl. mdth. 595 : employs it for all Ephori, including 



all the above species. 



1823. Ib., Tab. Meth. 46 : does the same. 

 1828. Horsf., Descr. Cat. Lep. E. Irid. Co. 67 : restricts the name to 



the blues, but only uses it for new species. 



1828. Steph., 111. Brit. Ent. Haust. 83: uses it for Argiolus and 



many others, all blues, including Argus. 



1829. Boisd., Index, 10: follows Godart. 



1830. Meig., Eur. Schmett. ii. 1 : employs it for the same, excluding 



the hair-streaks. 

 1832. Renn., Consp. 17: uses it for the blues only, specifying, of 



those given by Latreille in the first instance, Argus, Thetis 



(Adonis), Corydon, Arion, Semiargus (Acis), Argiolus, 



Alsus, and Dorylas. 

 1832-33. Swains., Zool. 111. ii. 133 : uses it for Cassius, one of the

1832-33. Boisd., Icones, 43 : employs it for the coppers only. 

 1832. Dup., Pap. France, Diurn. Suppl. 391 : the same. 

 1833-34. Boisd.-LeC., Lep. Amer. Sept. 122: the same. 

 '1839. Ramb., Faune Ent. Andal. 264: places the blues here again. 

 1840. Westw., Gen. Syn. 88 : specifies Arion as type. 

 1847. Doubl., List Br. Mus. 53 : follows Boisduval, as do most 



subsequent authors. 

 1870. Kirb., Journ. Linn. Soc. Lond. x. 500 : thinks that Corydon 



should be taken as the type, because figured in the first 



instance by Latreille. 



Latreille's own action necessitates its restriction to the blues ; but 

 Corydon cannot be taken as the type, since it belongs to llusticus, 

 established in 1810. Nor can Argus for the same reason. The only 

 other type of blues mentioned by him in 1810 is Boeticus, for which 

 Polyommatus must be retained. See also Lycaena. 



889. POLYSTICHTIS. 



1816. Hiibn., Verz, 18: Fatima (Cerea), Zeanger (Zeangira), Man- 

 dana (Mandane), Lucinda.
