Hesays, p. G3: "Some forms here classified as varietie.s may prove 

 to be valid species when their history is known, as, for instance, C. con- 

 tifjita, which is stated by the editor of the Casiadian Entomologist (vol. 

 1, p. 45) to be quite a constant form." At \). lioO he apiin refers to the 

 species and quotes a letter from ]\Ir. Saunders, claiming" that kcontei 

 and contUjua are valid species; but after ail, on the basis of the exam- 

 ples he then had, he does not change the synonymy as above given. 



In describing CalUmorplia rcversa he says (Ent. Am., I, 104) : " This 

 species has long been contounded with Lceonfti. Harris and Doubleday 

 discussed the question of their specific identity, and Canadian entomol- 

 ogists have long contended that two species were included under the 

 latter name, but, so far as I know, without pointing out the most rec- 

 ognizable character, which is to be found in the main transverse band 

 of the primaries. In Lecontei this starts from the inner margin and goes 

 to the apex, while in reversa it starts from the outer margin and goes to 

 the anal angle, being exacth" as in clymene. Just as is often the case in 

 the latter species, the transverse band is sometimes partly obsolete near 

 to the costa, and this seems to be the chief variation." 



This term embraces two very distinct forms, and he mistakes the type 

 of lecontei, which is incorrectly figured in the Z. & B. on PI. IX, f. 14. 

 Yet it is this very.form that he here describes as reversa, evidently now 

 considering mil i far is Harris as typical of lecontei. 



In the Sixteenth Annual Report of the Entomological Society of On- 

 tario, 188G, p. 38, Mr. F. B. Caulfield says : " I have only seen four 

 Canadian species, one buff, inierrupto-marginata,, and three white, Le- 

 contei, contigua, and one unnamed species which generally passes for 

 Lecontei, but certainly is not that species, as I have bred both species, 

 and the larva of Lecontei is larger and the colors are duller than 

 those of the larva of the smaller species. Lecontei has several varieties, 

 such as miUtaris Harris and conjinis Walk., and these varieties have 

 much more white on the wings than the type, or, in other words, it varies 

 in the direction of albinism, while in the smaller species the reverse is 

 the case, this species varying in the direction of melanism, in some 

 specimens the white spots being almost entirely covered. * * * 

 Contiguais a well marked form and varies very little, but, as I have no 

 specimens at hand, I cannot point out the distinctive features. I am, 

 however, satisfied that breeding the larva will in time prove that we 

 have three white-winged species, Lecontei, Contigua, and the smaller 

 form which now does duty as LeconteiJ' 



In arranging, under Professor Ililey's direction, the Museum collec- 

 tions of Arctiidw, I endeavored in this genus to make out all the listed 

 variations from an unusually abundant material, and L soon found that, 

 while there was a considerable variation, so that an apparently complete 

 series could be made, yet there was at the same time a change in the 

 pattern of the markings, and following out this idea I arranged the 

 species allied to lecontei into four distinct species, exclusive of tne two
