outward sinuations to base. T. p. line very strongly crcnnlate; from 

 costa over reuiforin, very oblique to the end of the cell, thence inwardly 

 and evenly rounded to inner margin. S. t. line irregular, indefinite, 

 consisting rather of a shade than a line, often defined in dark forms by 

 the paler terminal space. The ordinary spots vary in size and in dis- 

 tinctness; often the reniform is discolorous gray or yellowish. Some- 

 times both spots are distinctly outlined in black, and occasionally the 

 space between is darker, and the spots are interiorly connected by a 

 black line. Collar often paler, usually coucolorous. 



Tlie S harpes are rounded at the tip, and interiorly a corneous claw- 

 like projection is formed. The clasper is a single, long-curved, corneous 

 hook. 



Expands 38-45"'™ ; 1.42-1.80 inches. 



Habitat. — Maine to Georgia, Canada. 



Eather a variable species, and the specimens yet so much alike that 

 they are instantaneously recognized. Three of the varieties have been 

 named as species. EUmata is smaller, usually iialer, and has the ordi- 

 nary spots distinctly outlined; it has usually also the collar rather 

 paler, inclining to cinereous, though this is not constant; dilncida Morr. 

 is larger, usually' more reddish, the markings less distinct, often obso- 

 lete ; janualis Grt. is like this, but the reniform is discolorous. Among 

 the specimens labeled "types" by Mr. Morrison as many of the janu- 

 alis as of the other form are found, and Mr. Morrison evidently consid- 

 ered the forms as identical. In this I agree with him. In the larger 

 forms the collar is also often paler, varying from brighter red to 

 cinereous. 



Guenee describes the larva, after a drawing by Abbot, as having 

 nearly the same colors as the moth, i. c, the dorsal and subdorsal region 

 reddish, the lateral ashen, without well-defined lines, and only showing 

 some slightly darker subdorsal markings. Head ocher yellow. Collar 

 dark brown. Feet coucolorous. Pupa light red, with the membrane 

 covering the wings mixed with greenish. 



According to Abbot's figure, on Chrysanthemum. 



Mr. Butler has, long since the above was written, positively referred 

 dilucida to elimata as a sjMionym.
