174 THE CANADIAN ENTOMOLOGIST. 



1872 — Stretch, Zyg. & Bomb., 36, pi. 2, f. i, Gnophala. 

 1 88 1 — Butler, Papilio, I., 130, Gnophcela. 

 1888 — Bruce,* Ent. Amer., IV., 24, Gnophcela. 



var. contifiua Hy. Edw. 

 r88i— Edw., Papilio, I., 80, Gnophcela, 

 Habitat, Colorado. 



Mr. Bruce gives the food plant as Mertensia vh'ginica, and the date 

 in the Upper Platte Canon as July. The probabilities are that the species 

 is double brooded, the first brood appearing in May, the larva of the 

 second in July, imago late in July and early August. 



Genus Melanchroia, Hiibner. 

 18 1 6 — Hiibner, Verzeichniss, 173. 

 1854— Walker, C. B. Mus. Lep. Het., II., 386. 

 1862 — Clemens in App. to Morris Syn., 297. 



This genus I have made no study of, although there is considerable 

 material in the National Museum available for that purpose. Mr. Grote 

 never included the genus in his lists and apparently considered it extra 

 territorial. It is only within quite recent years that it has been placed by 

 Mr. Edwards among the genera of our fauna, though Mr. Stretch recorded 

 it in 1876 as found in Arizona. It is really a stranger to the rest of our 

 fauna — an intruder from Central America — but it seems necessary to 

 include it. 



The bibliographical references to the older authors are all at second- 

 hand, as, at the time I was studying their works and making notes, the 

 species were not recognized as belonging with us. This is, perhaps, a 

 good place to mention that, except where otherwise stated, all the refer- 

 ences have been verified, and, barring errors in transcription and type, 

 are correct.
