NORTH AMERICAN LEPIDOPTERA. 171 



parts of the lines, a large, quadrate, darker area, which rests ou the middle of 

 the costa, and extends rather moi-e than half way across the wing, containing 

 the reniform or discal spot. A brownish shade follows these outer lines, then an 

 outwardly curved, interrupted somewhat lunulated black line, strongest at its 

 inception on costa. Parallel with and near to the outer margin is a row of out- 

 wardly curved lunules, inwardly marked with gray and outwardly brownish to 

 the outer margin opposite each lunule. An irregular black line, shaded above 

 with gray, extends obliquely inward from apex. The fringes are brown, marked 

 with white between the veins. Secondaries rosy red, with a broad, gray, outer 

 margin. An irregular black loop at base ; a broad, siuuate, median line, and a 

 black shade margining the gray outer space, broadest on costa. Beneath, prima- 

 ries mouse gray, with three faint, dentate lines beyond the cell. Secoudaries 

 mouse gray, whitish between the median and outer bands and along inner mar- 

 gin ; a series of three dentate, median lines, uniting at middle and then as a black 

 band to inner margin. Expands 3.75 — 4.50 inches ; 94 — 112 mm. 



As variety decolorata Mr. Edwards describes a form from Florida 

 in which the rose-colored shade on the base of primaries and at the 

 sides of the abdomen is wanting. In all other respects the markings 

 are as in the type form. He adds that the species extends from 

 Canada to Brazil and reaches the extreme west of our continent; 

 also that it is abundant in the Hawaian Islands. 



Hab. as above. 



There is little variation in this species, except as above set out. 

 The species is not common usually. The larva of this species is 

 quite variable, as in others in this genus, and the variations have 

 been well described by Prof. Lintner. No history of the egg or 

 earlier larval stages has been written to my knowledge. The % 

 genitalia are, as to the supra-anal plate, like the others of this genus ; 

 the side piece not unlike celeus, while the clasper is moderately long, 

 stout, at tip divided into two curved, acutely terminated hooks, the 

 upper much more curved and at an angle with the other. The rosy 

 lateral spots of abdomen and on secondaries easily distinguish this 

 species.

Head moderate or small ; distinct, yet neither retracted nor promi- 

 nent. Eyes small, round, somewhat variable in size, usually very 

 distinctly lashed, but often the circle of hair becomes very much 

 reduced, and the term " lashed" must be a little liberally understood. 

 Antennte subfusiform, somewhat variable in the form of the tip, 

 which may be abruptly bent, or on the contrary be gradual and 

 somewhat curved. The tongue is long, stout and corneous. Palpi
