III one male from Albany, N. Y. (Lintner), tlie Tront is dull ochreons, 

 this sluule running up the orbits.

It differs from T. crocaUnta by the cream-white wings, the dull-ochreous 

 line on tlie tore wing, while the apex of the fore wing is not so pointed as in 

 T. croadlata or nspilntes, and there is no line reproduced beneath, and no 

 traces of a discal dot beneath. The hind wings are much more obtuse thtm 

 in T. crocnllata.

6 <? and G 9 . — Body and wings uniformly liright ocher-yellow ; wings 

 sliglitly speckled with brown. A broad, oblique, coffee-brown l^and on the 

 fore wings, extending from just beyond the middle of the outer edge to the 

 apex ; discal dot not large, but prominent on both wings. On the hind wings, 

 a single straight line, not reaching the costa (in three out of twelve speci- 

 mens the line is entirely wanting on the hind wings). Beneath as above; 

 the line most distinct toward the apex; the female paler and with a narrower 

 line on the tore wings tlian the male. 



Length of body, i , 0.65, 9 , 0.60 ; of fore wing, S , 0.58-0.83, 9 , 0.80- 

 0.85; expanse of wings, 1.75 inches.

It varies in tlie presence or absence of the line on the hind wings; in 

 three out of nine specimens, the liand on the fore wing is very broad, three 

 times as much so as in others. In a female from Iowa (Parker), with the 

 line present on botli wings, the wings are speckled much more than usual. 

 I found on examination of Guende's types that his T. aspilata is a pale variety 

 of his crocallata, without the band on the hind wings.
