THE CANADIAN ENTOMOLOGIST, S^ 



in another paper, to appear in the Journal of the New York Entomologi- 

 cal Society, The identification of the species is based on comparison 

 with specimens found in the collections of the United States ]\Iuseum, 

 labelled as from France, the specific label in the handwriting of Ashmead. 

 The evidence of the establishment of the identification is but presumptive, 

 yet even if wrong, it is still true that we have specimens of a species com- 

 mon to both continents, whatever the name of the species may be. Only 

 the specimens in the National Museum bear witness that it is J>raU7isis, and 

 their origin is not known. Nevertheless, Ashmead must have had good 

 reason for so labelling them. For the present, identification must hold. 



As I state elsewhere, the species is allied to both io/e Girault and 

 nigrellus Girault, and in this statement the species hercules Girault should 

 have been included also ; these are all American forms. From both 

 nigrellus and hercules Foerster's species may be distinguished readily by 

 reason of the fact that the marginal cilia of the fore wing at apex are 

 distinctly longer (by over a third, they are about two-thirds the greatest 

 width of the fore wings). There are a number of minute discal cilia scat- 

 tered under the venation of the posterior wing, the fore wings are less 

 regularly and uniformly fumated, and the proximal tarsal joints of all legs 

 are longer. Its other characteristics, as compared with those of the 

 American species mentioned above, are given in the papers referred to in 

 this connection. The posterior wing bears two lines of discal cilia along 

 each edge, the inner line of the two out some distance from the edge, 

 toward the mid-longitudinal line of the blade. 



In addition to the specimen oï pratensis, recorded elsewhere, as hav- 

 ing been captured in Illinois, I have since seen the following specimens, 

 kindly sent to me by Mr. H. L. Viereck, and belonging to the Connecti- 

 cut Agricultural College : Two slides bearing respectively a single male 

 and female specimen (one pair in all), and each the label, "New Haven, 

 Ct., I G May, 1904. H. L. Viereck, Taraxacum officmale." In the 

 United States the species occurs in Illinois (Urbana), and Connecticut 

 (New Haven), The Connecticut specimens have been returned to Mr. 

 Viereck, 



While on this topic, it is meet to mention the possible identities of 

 several other American forms with those of Europe, A species recently 

 described as Gonatocerus brunneus Girault may possibly be Gonatocerus 

 flavus Walker (so called), and my ( Stephauodes) Polynema psecas is very 

 similar, and possibly identical with Polynema enockii (Girault), a species 

 which Enock described as Stephanodes elegans (Stephanodes equals 

 Polyjiema ; elegans preoccupied in Polynema). I have considered them 

 distinct, however, as they seem so. Still they must be considered but 

 questionably valid until a better opportunity is afforded for comparing them.
