for the separation of genera will be discarded altogether by future 

 systematists, but I am far from competent myself to undertake or even 

 suggest reforms in that direction. 



As to the name adopted for this genus, I use Eupithecia because I 

 agree with those who claim that Curtis's name antedates that of Hubner. 

 There are some, I know, who hold the contrary opinion, and they will 

 continue to call the genus Tephroclystia, but it is to be hoped that the 

 error, into which nearly all our modern American writers have fallen, of 

 writing Tephroclystis will not be perpetuated. I am not sufficiently 

 acquainted with European literature to know who first made the mistake, 

 but certainly Meyrick in his "Hand-book" uses the wrong spelling, and I 

 think that probably Hulst and others have erred by following him. 



With the species already described I shall deal in date order. 



The names proposed prior to 1896, the date of Hulst's "Classification," 

 are 18 in number. 



In order of publication they are : 



1759, absynthiata, Clerck. 1867, luteata, Packard. 



1847, scriptaria, HerrichSchaeffer. 1873, geminata, Packard. 



1857, coagulata, Guenee. 



i860, gelidata, Moschler. 



1 86 1, hyperboreata, Staudinger. 



1862, anticaria. Walker. 

 1862, implicata. Walker. 



1862, explanata, Walker. 



1863, miserulata, Grote. 



1873, palpata, Packard. 



1873, interruptofasciata, Packard. 



1873, strattonata, Packard. 



1874, cretaceata, Packard. 

 1876, albicapitata, Packard. 

 1876, zygadeniata. Packard. 

 1876, ravocostaliata, Packard. 



Etip. absynthiata^ Clerck, Icones, VI, 9, 1759. — This species is dealt 

 with here, not because it occurs in North America, but because the name 

 has appeard on all our lists from the time of Packard to the present day. 



We have, it is true, several close allies to this species, vvhich will be 

 mentioned later, but the true absynthiata has not yet, I believe, been 

 found in America. We have no form nearly so red as the genuine 

 absynthiata is, and, moreover, in all our forms, so far as I known them, 

 the fringes are checkered^ while in the European moth the fringe is plain. 



Careful breeding of our forms and investigations as to their food- 

 plants will be necessary to make certain their specific distinctness and 

 limits. The larva of the supposed absynthiata has been found and
