and their long oblique exterior margin, as well as by ornamenta- 

 tion ; it is very distinct from the other species. Damalis, from Cali- 

 fornia may be known by its blue-grey color. Finally, I have a 

 female specimen from Texas, collected by Belfrage, which comes 

 near to Depilis, but may prove a distinct species ; it is numbered 

 " 697." Eiitolype Rolandi, has in both sexes the metallic thor- 

 acic tuft, unusual in the moths, and analogous to that found in 

 Tolype and Eiidryas. Our species of Dicopis are as follows ; Mti- 

 raiis, Electilis, Thaxteriamis, Damalis, Depilis and possibly an 

 undescribed species from Texas. 

 Chytonix sensilis, n. s. 



? . Larger than laspis and much darker. Eyes naked ; thor- 

 ax covered with flattened scales; abdomen strongly tufted. 

 Brownish fuscous, with a reddish stain over the subterminal line. 

 Stigmata a little paler than the wing, the reniform medially con- 

 stricted, enclosing a black shade, separated into an upper and 

 lower spot. Lines black, uneven, rather wide apart. T. p. line 

 running outwardly below costal edge, thence downwardly and 

 outwardly obliquely to over median nervules, with a slight inden- 

 tation opposite the cell. Below vein 3 it runs a little inwardly 

 and thence straightly to internal margin. Attached to it on the 

 submedian fold is an elongate, squarish, pure white spot. Sub- 

 terminal line uneven, toothed over median nervules. Hind wings, 

 blackish fuscous. Beneath paler, with a continuous dark, extra 

 mesial line and shade; on forewincrs the slight discal mark is sur- 

 mounted by a dark costal shade spot. Discal spot on sec- 

 ondaries a small annulus. Expanse 31 mil. Massachusetts, in Mr. 

 Thaxter's collection. I also saw a specimen determined as " ias- 

 pis'' in the collection of the Boston Society of Natural History. 

 I mention this because this erroneous determination is probably 

 still more widely spread. Guenee's Apamea laspis, the type of 

 Chytonix, is related, however, to Jaspidea {BryopJiila). Indeed, 

 it may be only a variety of his BryopJdla PalUatricula. Both 

 have a black sub-median dash across the median space, and the 

 vague white shading over median space above in PalUatricula ab- 

 sorbs the small white dot of laspis. I have referred both species 

 to Chytonix elsewhere. In the present form the white spot is more 

 elongate. The color is more reddish brown and the insect faintly 

 resembles Dryobota Stigmata. The ground color of Sensilis is a 

 somewhat pale, brownish fuscous, shaded with darker at the base 

 and on the median space inferiorly. In the disposition of the 

 darker shades there is a parity with laspis and PalUatricula, but 

 there is a red-brown tone wanting in its allies, while the insect is 

 darker and larger. The t. p. line is not so rounded opposite the 

 cell, the inner line not so oblique, waved, with a sub-median in- 

 dentation ; the lines do not appear so widely separate in sensilis 

 as in its allies.
