of the wings or lighter. The discal spot on the primaries is 

 black and distinct in most examples; there are two well defined 

 black dots between the discal and the base of the wing; one in 

 the place of the orbicular and the other marking the intersection 

 of the basal line and subcostal vein; the subterminal line is in- 

 dicated by dots in the veinules; there is a row of black marginal 

 lunules; fringes usually lighter than the wings. The secondaries 

 have the same hue as the primaries, the discal is blackish; in some 

 specimens.a faint mesial line appears, in others it is obsolete; mar- 

 ginal lunules as on the primaries; fringes concolorous or lighter 

 than the wings. Beneath the discals on both wings are dis- 

 tinct; also the marginal lunules; on the primaries from the base 

 to the discal dots there is a reddish wash; beyond this a smoky 

 space. All the wings above are often dusted with black scales. 



The $ expands 38 mm. The color is darker than that of the 

 S ; the markings are similar. 



The palpi of both sexes are rather slender, horizontal, and ex- 

 tend to the tip of the clypeal spine; the slender terminal joint 



is clothed. The very stout clypeal spine 

 (Fig. 3) is concealed by the long dense 

 hairs of the front, which thus presents a 

 cone of broad base and rounded apex. 

 The ovipositing apparatus of this moth 

 appears worthy of special description 

 and illustration. It is rather complicated 

 as it is in those of its congeners known 

 to me, but differs sufficiently to be of in- 

 terest; moreover, the manner in which 

 the eggs are placed is known, which lends additional interest to the 

 structure which is made to accomplish so nice a piece of work. 

 Figure 2 exhibits the strangely modified terminal rings of the ? 

 abdomen. Of the three modified joints, the last is the short tubular 

 ovipositor proper, usually concealed within the first of the three. 

 The first piece (a) is chitinous, and supports the rest of the ap- 

 paratus; the second piece articulates with the first at the upper 

 side. On the lower face are two broad teeth (d) pointing back-
