NORTH AMERICAN I.EPIDOPTERA. 149 



at the apex and the anal angle, leaving the rest of the terminal space olive gray. 

 Secondaries dull red. with a darker, more or less complete terminal band, which 

 is greenish towards the anal angle. Beneath, the primaries are pale reddish, ex- 

 cept the costa and outer border, which, together with the secondaries and body^ 

 are greenish gray ; there is a (central slightly darker median band on secondaries. 

 These colors vary in intensity, and the maculation varies in distinctness. Often 

 there is considerable sufTusiou of the primaries and this form, which is rather 

 more common southwardly, is the cnotus of Hiibner. Often the reddish sufiTusion 

 becomes predominant, and the insect resembles cluerUus quite strongly. The 

 more rigid transverse bands of c/tceriZ«s will, however, always prevent confusion. 

 Expands 2.10—2.50 inches; 53—62 mm. 



Hab. — Canada to Georgia ; we.stward to Missouri, Iowa. 



The clasper of the S of this species is rather short and broad, 

 with a rather hirge, spooii-shaped tip. Otherwise as in choerilus. 



This insect is ratlier common, and is the form most frequently 

 taken at sugar. 



Its larva is of some economic importance, as it feeds on grape, and 

 since Smith and Abbot it has been frequently figured and described.

Head and thorax dark green, varied with greenish yellow; the abdomen 

 greenish yellow or buff, varied with darker green, especially along the middle 

 andon the hinder edge of the segments. There is a whitish line along the 

 side of the head and thorax over the base of the wings, and a dorsal line ex- 

 tending from the head to the tip of the abdomen. The collar and patagiae are 

 edged with white. Primaries green, of various shades; a deeper curved shade 

 band from costa beyond middle to inner margin at basal third. A .series of three 

 curved white lines from costa to the base of the wing, ending in a grayish blotch ; 

 the lines are sometimes distinct throughout, but more usually the lines become 

 olive gray below the median vein. Often the space between the second and third 

 of these lines is darker. At the inception of the third line on costa is a pale 

 shade, variable in extent toward the middle of the wing, but re.aching to the 

 shade band above described, and which is margined inwardly with white to the 

 middle of the wing, the white gradually shading into olive gray. At about the 

 outer fourth is another series of three whitish transverse lines running nearly 

 parallel to the outer margin. The first runs into the .second before the middle of
