on the inside, in which the bi-tufted maxillary palpi are concealed. 



Male antennae with a short, scaled, basal process. Fore wings 31- 



veined; in the male, there is a costal fold beneath 



at base, furnished with a fringe of transverse scales; 



the subcostal nervules are crowded, so that their exact 



disposition is a matter of uncertainty. There is a 



vitreous spot toward the base of the cell, just beyond 



the interior line. The cell is open, and narrower 



than in the female. The female wing is destitute of 



the vitreous spot, the fold, and fringe. Veins 4 and 



5 intersect, and the cell is partially closed from both 



sides. Veins 8 out of 7, 9 out of 8. Hind wings 8- 



veined ; 8 out of 7 ; 4 and 5 joined on one stem; cell '^'^•^' ? 



closed. The fore wings are broad, with rounded or convex costse in both 



sexes. 



Dr. Clemens describes the third palpal joint as being very long, and 

 concealing the maxillary tufts. But I see that it is plainly the second 

 in a new Texan species, of which I here illustrate the venation of the 

 female wings. Ivl ])latanella and asperatella^ the third ^omt of the labial 

 palpi is difficult to make out; but I believe it more likely to be small, as 

 is usual, than that the males of these two species should make an 

 exception to the general palpal structure in the family. In both males 

 and females of as;peratella, I believe to make out the third joint distinctly; 

 it seems longer in the latter. 



Professor Zeller describes three species, militella, Isis, 1848, p. 880, 

 rohustella, Isis, p. 881, and melanogrammos, Verb. Zool.-Bot. Ver. p. 

 5i6, tab. iii, fig. 24 a, h, 1872. 



Dr. Clemens redescribes the genus under the name of Lantha])he^ and 

 states erroneously that it appears to be congeneric with Acrohasis of 

 Zeller. The genus is very close to Toripalpus, but clearly distinguished 

 by the 11-veined i^rimaries and the shape and fold of the male wings.
