114 THE CANADIAN ENTOMOLOGIST. 



black heap so carefully together, for a stranger to pick out one and toss 

 it over to the yellows, shows a degree of irreverence for Hiibner' s arrange- 

 ment that is disturbing. So it happens, that in the various works of Mr. 

 Scudder, Troilus has gone by three different generic titles within five years, 

 namely, Papilio Troilus, Pterourus Troilus and Euphceades Troilus J Now 

 all this trouble could have been avoided had the genus been called 

 Pterourus Scudder, as it really was. Scopoli had no more to do with 

 Scudder' s genus Pterourus than had Julius Caesar. 



All the first 18 coitus of the first 2 families of the Archontes are put 

 by Kirby in Papilio Linn., he paying no heed to the Verzeichniss divisions 

 of this genus. The 4th coitus, 1st family, contains 6 species, of which 

 our Cresphontes is one. Another is Pelaus Fab , which is given in the 

 Verz. as a synonym of Torquatus Cram., and looking up the latter in 

 Kirby, it stands as male of a distinct species whose female is Caudius 

 Hiibner, which in the Verzeichniss is in the 2nd family Priamides, separ- 

 ated by one family and nine coitus from its mate ! 



In 5th coitus stands Pammon Linn. Its variety Mutius is in the 6th 

 as are also its females, Theseus and Romulus. 



In the 2nd family, Echemon Hiibner is male, and is in the 1st coitus, 

 while its female, Echelus,'is in the 2nd coitus. So in 1st is Tellus, which 

 is the female of Sesostris, in 2nd. And Marcius in 1st is female of 

 Aeneas in 2nd. And Anchises Linn, in 1st is a synonym of Lysander 

 Cramer, which is in the 2nd. 



In the 6th coitus are two species only, one of which stands in Kirby 

 No. 19 on the list of Papilios, the other No. 91. And all through these 

 two families the species skip about in Kirby from one part of Papilio to 

 another, two adjoining species in one coitus being often separated by 

 species which go to form parts of several other coitus in the Verzeichniss. 

 Thus, between Anchises Cramer and the next species, Echemon, of the 

 Verz., stand seven species in Kirby, all of which are enumerated by 

 Hiibner, and are scattered over 2 families and 3 coitus. So between 

 Ulysses Linn, and the next in same coitus, Philenor Fab., stand in Kirby 

 23 of Hiibner's species, from 2 families and 9 coitus. 



What better illustration could be given of. the true nature of this 

 unnatural system than is displayed in these Papilios, the coitus based on 

 no tangible character, the species raked together in heaps according to 

 color or size of wing ; males parted from their mates, varieties from the 

 parent species, one dimorphic form from its fellow ; congeneric species in
