This finally determines the fact that Hampson's description does 

 not apply to Snozvi, whereas it does very accurately describe this 

 Canadian species, for which I herewith propose the name diversigna, 

 because of the fact that the sign is exceedingly variable. 



A few words now in regard to Snowi. I know of but two abso- 

 lutely authentic examples of this species, and both are before me as 

 I write, and are figured herewith. Several museum collections have 

 specimens labeled " Snozvi " but they are always from Colorado. 

 Bruce and others have distributed a Colorado form under this name, 

 some of which I have readily recognized as Sackeni, while a few 

 have been quite puzzling, a question arising as to whether the 

 brownish color had been the true color or whether it was due to the 

 age of the specimen. Of course it is possible that this species may 

 exist in Colorado, and I have myself two or three of Bruce's speci- 

 mens about which I have not yet fully decided. 



The two authentic specimens of Snozvi to which I have alluded, 

 are, first a specimen loaned me by the University of Kansas which 

 acquired Prof. Snow's collection. This specimen carries a printed 

 "TYPE" label, but no manuscript label in Edward's hand. The 

 locality label reads : " Near Hot Springs, Las Vegas, N. M., 7000 ft., 

 July, '82. F. H. Snow." (See Plate XV, fig. 3.) 



The second specimen is one presented by Prof. Snow to Mr. 

 Cramer, passing from him into the possession of Mr. Jacob Doll, 

 and from Mr. Doll to myself. This carries a printed locality label 

 the exact facsimile of the other except that the date is " Aug., 82." 



In Edwards's description of Snozvi 3 he does not state the date of 

 capture of the single specimen of Snozvi from which he described his 

 species, but on same page he dscribes Heliothis sitavis, taken by 

 Prof. Snow at the same locality, Aug., 1882, which at least indicates 

 that Prof. Snow was collecting in that locality in August as well as 

 in July, 1882, the date on the supposed "type" of Snozvi. I raise 

 this point because I am of the opinion that the July specimen is not 

 the true type, being 35 mm. in expanse, whereas Edwards tells us 

 that his type expands 30 mm., which is exactly the expanse of my 

 August, 1882, specimen. It therefore seems at least credible that the 

 labels were accidentally exchanged and that Prof. Snow really let 

 Mr. Cramer have the true type. Moreover, the description fits the
