THE CANADIAN ENTOMOLOGIST. 237 



species known to Hlibner, I am of the opinion that it should be regarded 

 as the type of Gmiris. Hiibner has given an excellent figure of this 

 species under the name of Hemerophila pcrlceta Albertiaiia in his 

 Sammlung exotoscher Schmetterlinge, Vol. I., pi. 213 (1823). Zeller, 

 who studied several examples of this species with his usual care, placed it 

 in the genus SimcBihis. We may therefore regard Gauris as a synonym 

 of Hemerophila. 



Hiibner established the genus Choreutis in his Verzeichniss, p. 373, 

 with five species under it, all of which, except diana and scintiiulana, 

 Hiib. (a synonyn of t?iyllera?ia, Fab.), are congeneric with pariana, and 

 have been placed with it under Simcethis, which may now be replaced by 

 Hemerophila. The last species, myllerana, has been taken as the type of 

 Simcethis, while diana has been placed with oxyacanthella, L., and its 

 allies, but its structural characters differ so much from the others that I 

 feel justified in following Guenee, who separated it and established the 

 genus Orchemia for its reception. 



Immediately following Choreutis, on the same page of the Ver- 

 zeichniss, Hiibner established the genus Porpe, with only one sjiecies 

 under \\.,fibrana (a misprint for vibraiia, Hiib.), and as this species is 

 congeneric with myllerana, Porpe must fall as a synonym of Choreutis. 



It was shown by Dr. Scudder in his " Historical Sketch of the 

 Generic Names Proposed for Butterflies," p. 96 (1875), that although the 

 title page of Hiibner's Verzeichniss bears the date of r8i6, there was 

 internal evidence sufficient to prove that it was not all published at that 

 time. I have only concerned myself with the time of publication of the 

 part containing the Microlepidoptera. There is a reference on page 312 

 to the Third Century of the Zutrage, the introduction to which is dated 

 Aug. 27, 1825, but this page is in a signature which begins on page 305. 

 The Third Century of the Zutrage, on page 34, makes reference to page 

 294 of the Verzeichniss, but this page is in a signature which ends with 

 page 304. I therefore conclude that the first 304 pages of the 

 Verzeichniss were published before Aug. 27, 1825, and the pages follow- 

 ing, between this date and the tniie of Hiibner's death, which occurred 

 Sept. 13, 1826. It is barely possible that this part of the Verzeichniss 

 may have been published late in 1825, but as Hubner himself made no 

 reference to it in August, it seems more probable that it could not have been 

 prepared and published before Jan., 1826, and therefore I have adopted
