21. Tliccla cryphon is also easily separable from eastern niphon. 

 I think larval investigation of the four species just cited would give 

 ample proof of their validity. 



22. TJiecla dmnctorum, Dr. Skinner calls a synonym of the Euro- 

 pean rubi Linn., but I prefer to call it distinct, and Messrs. Haskin 

 and Grinnell have pointed out the differences in a paper in the Ento- 

 mological News, Vol. XXIII, p. 3. 



23. Polyommatus hypophleas was described in the 1852 paper by 

 Boisduval. Oberthiir does not figure it. 



24. Polyommatus helloides, • 



25. Polyommatus gorgon, and, 



26. Polyommatus xanthoides are all well known. 



27. Polyommatus arota is not commonly found in collections but 

 is, I feel sure, a good species distinct from virginiensis Edwards. 



28. Lycccna amy n tula, and, 



29. Lyccrna exilis are easily recognized. 



30. Lyccena antcegon is the only synonym of the 1852 paper. It 

 falls before acmon Doubleday and Hewitson, described in the same 

 year. 



, 31. Lycccna xcrces, and, 



32. Lycccna sccpiolus are easily recognized. 



33. Lycccna icarioidcs I do not think so well known. It is con- 

 stantly confused with Lycccna erymus Boisduval which is placed as a 

 synonym of it, in our check lists. The figure shows it to be at least 

 a distinct variety. 



34. Lycccna pJieres. 



35. Lycccna hetcronea, and, 



36. Lycccna cnoptes, present no difficulties. 



37. Lycccna piasus furnishes the most interesting discovery of the 

 paper. This name has been long attached to a western form of our 

 widely spread and variable Cyaniris ladon Cramer (or Lycccna pseu- 

 dargiolus Bdvl. and Le Conte) and it is a most remarkable case of 

 misidentification. W. H. Edwards seems to have been responsible for 

 placing it .under pseudargiolus and later writers have followed him. 

 Lycccna piasus is the butterfly that is now commonly recognized undef 

 the name of sagittigera Felder, and curiously Boisduval redescribed 

 it as rhcca in 1869. It is a much named butterfly as W. H. Edwards 

 named it twice, Reakirt, Behr and Felder once each, and Boisduval 

 himself twice, his first name standing.
