its color to a change in the food plant. I learn from Mr. Behrens that 



four specimens were obtained, all agreeing with each other. The Catocala 



is, I have no doubt, the form referred to by me (Pacific Coast Lepid., 



No. 14, Proc. Cal. Acad Sc, 1875) as having been seen by the late Baron 



Terloo at San Jose, Cal. I think it a good species, and in this view I am 



sustained by those excellent authorities on Catocala, the Rev, G. D. Hulst 



and Prof. G. H. French. 



Hy. Edwards. (New. York.) 



Papilio Rutulus, var. Ammoni, Behrens. — A very peculiar form, in 

 which the ground color of all the wings is of a deep but rather dull 

 orange color, and the bands and marks of the upper side all rather 

 broader and more distinct than in the normal form. The orange color 

 prevails also on the lower-side, though a little mottled with lighter shades. 

 Four specimens, male and female. Nevada. Taken by my friend, Herr v. 

 Ammon, of San Francisco, in whose honor it is named. 



Catocala Eld a, n. sp., Behrens. — Allied to C. Relict a, Walk., and 

 more closely to its variety, C. F/irynia, Hy. Edw. It differs from this, 

 however, by the superior wings being of one shade of grizzled gray, the 

 whole surface covered with mottled scales obscuring all the lines except 

 the t. p., which is straighter than in C. ReliHa, and less deeply toothed. 

 The orbicular is very large and distinct. The inferior wings are very 

 much like those of C. Reli^a, only the medium band is much narrower 

 than in the Eastern species. On the under side the black band and 

 ■discal spot are very distinct, black, and not shading into brown, as is 

 usually the case with the common species. It is also smaller, the expanse 

 of wings being only 68 mm., while thai of C. ReliHa averages 78 mm. 

 Three examples. Portland, Oregon. Taken at the light of electric lamp. 



CORRESPONDENCE. 



Editor Can. Ent. : Allow me to correct two mistakes in my paper 

 on the Bombycidce, p. 1^6 et seq. of this volume. For "oval" p. 157, line 

 3, read "oral." For "North American," p. 159, line 17, read "American," 

 as it is, indeed, evident from the context, that I wished to credit the 

 Ceratocampince to both North and South America. It is, I believe,
