The type, numbered 1711, is in the Cambridge Museum. 

 It bears Zeller's green label and name in his own handwrit- 

 ing — Blastobasis fluxella Z., Dallas, Texas, Boll. 



The third palpal joint is certainly more than one-half the 

 length of the second ; palpi not very slender and divergent. 

 Basal joint of antennae broad, not longer than wide ; pecten 

 shorter than width of joint. Head and thorax sordid grayish- 

 white, the latter purplish-brown anteriorly, this color extend- 

 ing across the patagia to'base of costa of forewings, the latter 

 moderately wide, not acutely pointed, base fuscous, the black 

 dot in basal portion of fold is not evident ; the angulated 

 fascia is nearly at two-fifths the wing length, beyond the 

 fascia, the wing is more densely dusted with fuscous, just 

 beyond the spots at end of cell is a somewhat conspicuous 

 costal and dorsal spot ; cilia grayish-white with scattered 

 white scales. Hindwings nearly as wide as the forewings, in 

 basal portion, strongly narrowed towards the apex, the latter 

 pointed ; cilia a trifle over 1. Veins 3 + 4 long stemmed, 5 

 connate with stem. In a specimen in Lord Walsingham's 

 collection vein 5 of hindwing arises out of stem of 3 + 4, but 

 as elsewhere stated, this is a variable condition and of no 

 diagnostic value.

Relative to this species Mr. Chambers expresses himself 

 as follows : 



" H. chalcofrontella Clem, is so variable a species that it is possible 

 this may be a variety of it ; but it is not one of the described varieties. 



" Whitish, dusted lightly with dark purplish-brown, the dusting dense 

 on the second joint of the palpi. There is a purplish-brown patch at 

 the base of the costa, a small one about the middle of the costa, a 

 small one opposite to it on the fold, a small one on the disc opposite 

 the space beween the other two and at the end of the disc, and a row 

 of small dots around the apex at the base of the cilia. Alar expanse 

 one-half inch. Season, August." 



I have carefully examined the type in the Cambridge 

 Museum, and have no hesitancy in pronouncing this species 

 absolutely distinct from chalcofrontella and its varieties. The 

 specimen, a male, is unspread, wings of left side wanting, 

 markings of right forewing difficult to discern on account of
