no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 205 



The discal ocellus varies greatly; in one S from Brunswick, Me., it is reduced to one- third 

 the size of that in the hind wings, and only extends to a little more than half way across the 

 discal cell, while there is no clear vitreous center (that in the ocelli of the hind wings is very small) , 

 the yellow ochre oval spot being solid, opaque, with a few blue scales on the inside; on the left 

 wing the yellow spot is still smaller, shorter, and irregular. 



[Geographical distribution. — Very widely distributed over the North American continent, 

 especially east of the Rocky Mountains. The following localities are from the records of the 

 United States Department of Agriculture: New York (Pawling, Brooklyn); New Jersey (Wald- 

 wick, Hammerton); Pennsylvania (Dreshertown) ; Ohio (Toledo); Illinois (Man- 

 chester, Malta) ; District of Columbia (Washington) ; Maryland (Towson, Hagers- 

 town); Virginia (Farmville, Manassas, Norfolk); South Carolina (Summerville, 

 Edisto Island) ; Alabama (Montevallo, Greensboro) ; Georgia (Thomasville, Bruns- 

 wick); Temiessee (Washington College); Florida (Jennings, Eustis); Louisiana 

 (New Orleans); Kentucky (Frankfort); Texas (Paris, Clear Spring); Kansas 

 (Oswego) ; Missouri (Cadet, St. Louis) ; Colorado (Fort Collins) ; Oregon (Jefferson) ; 

 California (Fillmore, Niles, Mountain View).] 



[Mr. T. Pergande bred three T. polyphemus from cocoons found by Prof. 

 Comstock on water oak at Macon, Ga. He notes: "The moths are of a 

 purplish color, appearing different in this respect from the northern form of fig. w.— Teiea 

 T. polyphemus."] ^ ^f™ 



[Prof. M. H. Swenk reports (litt., 1912) that in Nebraska T.polyphemus occurs spur; shiny, 

 across the State, at least northwardly. "It is common in eastern Nebraska, and Wlt , h inner 



' ^ ' surface cov- 



Mr. Dawson has taken it at Gordon, Sheridan County, and in Monroe Canyon ered with very 

 Sioux County."] "Found from British Columbia [eastward] (but rarely) across the " t n ffi e short 

 prairies to Manitoba. It is one of our most abundant species of largo moths through- 

 out Ontario. * * * I have seen it in Montreal collections." (J. Fletcher, litt., 1900.)

Two 9 from Prescott, Ariz., present the following characters: They are of unusual size. 

 The light ground color is as pale as my lightest northern 9 , while the dark middle portion of 

 the wing and the dark spot inclosing the ocelli of both pahs of wings is of much greater extent 

 than in any examples from the New England States. 



This variety of the southwestern or arid region of Arizona and New Mexico differs from the 

 normal northeastern forms in the basal line showing more white, while the black outer edge is 

 wider and more distinct; between this black and white band is a narrow deep ochreous line; 

 the rest of the line from the median vein to the inner edge of the wing is a simple slightly curved 

 dark brown band. The extradiscal is (on the fore wings) a straight broad black-brown band 

 of even width extending to the two costal spots, but with no gray-lilac shade beyond ; on the 

 hind wings this band is wider and regularly curved. Between this and the ocellus the wing is 

 unusually blackish, and between the extradiscal and the ocellus is a faint brown line which curves 

 in a little before reaching the costa (this line is not present in northeastern examples). The 

 roseate patch near the apex behind the two costal black spots is more distinct than in the north- 

 eastern examples. Ocelli of the fore wings large, extending from the 4th II to the 1st median 

 or almost to it; the vitreous or clear center round, as wide as long, and the whole ocellus sur- 

 rounded by a broad diffuse black ring, which is prolonged to the 2d median vein in one example, 

 forming a large triangular black patch, which interrupts the transverse brown line. (In the 

 other example the black only reaches the 1st median vein, and the brown line is farther away 

 from the discal spot, nearly one-half way between the extradiscal line and the spot.) 



Discal spots of the hind wings very large, though the ocellus itself is a little smaller than 

 that in the fore wings. The blue crescent is wide and intense in hue next to the ocellus; the
