Ypsia umbripennis, n. s. 



^ . Size and markings of undularis ; black with the median space of 

 primaries inferiorly and base of secondaries brownish. At once dis- 

 tinguished from undularis by two-white linear shades accompanying the 

 t. p. line and before it, from disc to internal margin. The lines and out- 

 line of the reniform velvety black. Subterminal line marked with whitish 

 opposite the cell. Hind wings with the white linear shades from the cell 

 to internal margin. Beneath dark brown with empty reniform and trans- 

 verse lines. Head and thorax black. Expanse 43 mil. Grimsby, Mr. 

 Pettit ; London, Mr. Saunders. 



Very much like undularis, but noticeably different by the white lines 

 on both wings. This may be Walker's variety of " squaniularis " ; if so 

 he has not unlikely transposed coricias and undularis.

In a collection sent by Mr. Belfrage from Bosque Co., Texas, are 15 

 generally fresh specimens of this genus which I have carefully examined. 

 The type of hydromeli <J is numbered 527 (violet label), the % 246 (red 

 label). The orange dots following the fuscous blotches of the subterminal 

 line are less evident in the male, and at the base of the wing the orange 

 powdering is less prominent. I am inclined to consider seven specimens, 

 two males, five females, captured from May 3rd to May 21st, as typical. 



The variation is in the extent of the orange shadings. The abdomen 

 of the male is a trifle longer, and the hind wings more purely whitish. 

 The antennae in both sexes are feathered, the tips being simple ; in the 

 males the pectinations are a little longer. The hind wings of one female 

 are almost blackish, save the bases, and there is but the slightest trace of 

 orange on fore wings ; another is very small, measuring but 26 m. m., the
