244 REVISION OF MAMESTRA SMITH. 



Ectypa is a very pretty species, as its synonym, hella, suggests. The 

 maciilatiou is uiiicb of the same type as the preceding, but prettily 

 contrasting; the s. t. line unusually prominent, pale; the claviform large 

 and black filled. The only specimens thus far known are : One in the 

 Museum collection (0. V. R. ), taken by Mr. Andrews in New Jersey ; 

 the type of the species in Mr. Meyer's collection from West Virginia, 

 and the type of hella in Mr. Neumoegen's collection, also taken in New 

 Jersey. 



In tabular form the species divide as follows : 



Primaries with a violet gray or reddish flush. 

 Chxviform very small. 



Color very even, size large beanii 



Color not even, niaculation contrasting, size smaller legitima 



Claviform rather large. 



Larger, s. t. line sinuate, not preceded by black, sagittate marks lilacixa 



Smaller, s t. line very even, preceded by black, sagittate marks rugosa 



Primaries sordid luteous gray to blackish brown. 

 Rather narrower winged ; a distinct, curved, basal black mark to t. a. 



line NOVERCA 



Broader winged ; no basal dash or black mark. 



S. t. line not preceded by black spots or shades, color very even goodelli 



A somewhat contrasting, pale, s. t. shade in submedian interspace ; 



a small W in s. t. line quadrata 



S. t. space even; no Win s. t. line. Color even, dull; maculatiou 



obscure ; claviform concolorous or wanting obscura 



Brightly marked; s. t. line unusually distinct, pale; claviform 



black; contrasting ectypa

Expands 40 """ (l.CO inches). 



Habitat. — Illinois, Texas, % Colorado. 



I have had two females only, the one fully agreeing with the type, 

 from Texas; the other, somewhat aberrant in maculatiou, from Colorado. 

 This latter may eventuallj* prove distinct when males are available, 

 but at present I do not care to separate them.
