(7) Cratacgi is usually placed by European authors in the genus 

 Aporia Hbn. which has crataegi as sole species and therefore becomes 

 a synonym of Pontic ; both genera, however, fall before Ascia Scop. 

 (1777) with crataegi as "first species" type, although Scudder has 

 arbitrarily fixed on monustc as type. For most of the species included 

 in Dyar's list under Pontia another generic term must be used as they 

 are not congeneric with crataegi Linn. Picris Schrank is unavailable 

 as we noted under Parnassius; if Tentamen terms are accepted, Man- 

 cipium Hbn. with brassicae as type can be used for some species and 

 Sytichloe Hbn. with callidice as "first species" type for others. 



(8) The N. Am. species catalogued under Syncliloe cannot re- 

 main there with callidice as type. J. Rober in Seitz, Macrolepidoptera 

 of the World, has also restricted Sytichloe to callidice and allies. For 

 the species at present under Syncliloe the genus Eucliloe Hbn. with 

 ausonia Hbn. {belia Esp.) as type must be used (vide Beutenmueller 

 Bull. Am. Mus. Nat. Hist. X, 236). 



(9) Rober in Seitz, Macrolepidoptera of the World, places the 

 N. Am. species of this and the following two genera under the one 

 genus Catopsilia Hbn. This latter genus with type crocale Cram, has 

 certainly the priority, and if pliilea L. and eubitlc L. are congeneric as 

 listed by Dyar, then Callidryas Bdv. will fall before Plioebis Hbn. It 

 is beyond the scope of this paper, however, to determine the generic 

 boundaries. 



(10) Zerene Hbn. (1816) will fall before Colias Fabr. (1807) 

 with palaeno L. "first species" type, which will restore a well-known 

 genus. Scudder's fixing of caesonia as the type of Zerene is purely 

 arbitrary and based on no scientific grounds (vide Proc. Bost. Soc. 

 N. H. IX, 103). Megonostoma Reak. with type caesonia will replace 

 Zerene in the catalogue. 



(11) Eurymus will fall before Colias Fabr., which thus again 

 is restored to general use. 



(12) Rober (i. c.) unites the genus Pyrisitia Butl. with Terias, 

 stating that the difiference in venation on which the genus was based 

 is extremely variable in the same species and useless as a generic 

 charactr. Terias Swains (1820), type liecabe, will, however, fall be- 

 fore Eurema Hbn. (1816). 



(13) Paphia is separated by some writers, under the Tentamen 

 name of Dryas Hbn., from the other Argynnids but most European
