CO THE CANADIAN ENTOMOLOGIST 



"Eden Vale, Colo." read "Eden Vale, Calif." This species seems 

 to have quite a wide range and is more common than the others. 

 I had specimens from Mr. E.'H. Blackmore, Victoria, B. C, and 

 have heard that a specimen was even taken in Newfoundland, 

 but cannot verify it. 



Type. — 1 9 in my collection, 4 9 s, Mr. Broadwell's col- 

 lection; 1 cf in Mr. J. G. Grossbeck's collection, which was sent 

 me to compare. 



H. edenata is an early species on the wing, occuring from 

 April 5 to May 4, 1913, at Victoria. 



20. Hydriomena cliiricahuata Swett (Can. Ent., Vol. XU, 

 p. 231, July, 1909, Barnes and McD., Contrib: Nat. Hist. Lepid. 

 North Am.', Vol. I, No. 4, 1912.) 



This species is figured by Drs. Barnes and McD. in their 

 valuable work, in which a clear idea of the markings is given. It is 

 quite a small and slender species and has a peculiar narrow 

 mesial line, and the line on hind wings show only as dots. 

 This is a very rare species and does not approach any other 

 very closely, unless it looks superficially like a small barnesata 

 with narrow mesial space. 



Types. — 2 d^, Huachuca Mts. and Chiricahua Mts., Ariz., 

 in Dr. Barnes' collection. 



20. Hydriomena similaris Hulst, Trans. Amer. Ent. Soc./ 

 Vol. XXIII, 1896, p. 284. 



This, species is very closely allied to ruberata, from which it is 

 difficult to distinguish. There is a peculiar pale blue and faded 

 rusty look to the bands in similaris, while in ruberata they are 

 bold and well defined and either smoky or brick red as the type 

 species. Similaris occurs in June and July, while ruberata, to my 

 knowledge, is only found in early May. This is rather a common 

 form in Nevada, and, strange to say, is correctly labelled in most 

 collections. How^ far it varies I cannot say, as my material has been 

 somewhat limited, though it is not a rare species. 



Type. — Colorado, Mr. Graef. 



22. Hydriomena ruberata Freyer (Neu. Beit. Schmett.. 

 Vol. I, p. 67, pi. 36, f^g. 2, 1831). 



This little-understood species was first determined for Rev. 

 G. W. Taylor by Mr. Lewis B. Prout of London, England. Mr.
