all of the information on the subject that I have been able to locate, 

 hoping it will be of assistance to others who may become interested in 

 this group. 



After each description I have also stated the chief claims for specific 

 difference, usually in a comparative way to quickly assist in the identi- 

 fication. I have found one reference to American species of this genus 

 by Zeller in Verh. Zool. Bot. Gesell. Wien, XXV, 320, 1875, of which 

 the following is a literal translation : 



" Choretitis preiiosana Duponchel, Suppl. IV, 182, pi. 65, f. 9. 



" Choretitis vibraiia var. anstrali^ Zeller, Isis, 1847, P- ^43- 



"This species, which is found in the vicinity of the Mediterranean Sea, is separated 

 from bjcrkandrella Thunb. {vibrana Hubn.), only by its smaller size and lighter 

 color, the markings are identical but the fore wings of bjerkandrella have not always a 

 less convex hind margin. Besides /r(?//(7Jrtwa differs somewhat in size and the 9 is 

 somewhat smaller than the $ . 



" The seven North American examples before me are still smaller than the J 

 of the European pretiosana. In the four from Texas, the two curved bands composed 

 of raised scales (the first rather straight before the middle, the second bent and en- 

 larged by two-thirds above the middle) are light gray, in the three from Ohio, which 

 Schlager determined as australis, are pure white, so that the scales, under an ordi- 

 nary lens, on the outer band are only indistinctly visible. (If these white bands are 

 constant, these specimens may be separated as var. ohioensis. ) I have taken in 

 Syracuse (Asia- Minor?) a similar 9 less distinctly white, but agreeing otherwise. 



" That the specific identity between the American and European examples is cer- 

 tain, and as an importation is not to be thought oi pretiosana can be added to the 

 species originally common to both continents." 



I feel quite sure had Zeller the opportunity for studying large series 

 of specimens from all parts of North Amerfca, he would have modified 

 the views as expressed above, in fact Lord Walsingham, who has, 1 

 believe, the identical Texas and Ohio examples referred to by Zeller 

 has compared them with specimens of carduiella and pronounces them 

 distinct and even expresses a doubt that the European forms occur in 

 this country at all, as will be noted in copy of his letter under the 

 caption of carduiella. 



Lord Walsingham', in Trans. Am. Ent. Soc, 1882, Vol. X, p. 

 167, refers to bjerkandrella and says : 



" This species has not, so far as I am aware, been recorded from North Amer- 

 ica. I have received it from Miss Murtfeldt, from whom the specimens in Professor 

 Fernald's collection were also obtained. It occurs also in California, together with 

 a form identical with, or very closely allied to, Choreutis silphiella Grote (Papilio, 

 Vol. I, p. 40), which must probably be regarded as distinct."
