end ; the apical and post-apical nervules arise at a common point, from which 

 is given off a faint discal vein, which is obsolete in the middle (?) and gives 

 off on the costal side of the wing a disco-central branch ; another arises on the 

 median side from a short vertical stalk. Median vein 3-branched, the posterior 

 opposite the first marginal. In the hind wings the subvitreous spot is larger 

 than in the fore wings and angulated ; the tip is very obtusely rounded, and the 

 hind margin is emarginate opposite the disk, which is very broad. The costal 

 and subcostal veins cross each other about the middle of the disk and are 

 continued to the base of the wing separately ; the subcostal is bifid beyond the 

 origin of the discal vein which is faint and angulated, and the branches of the 

 subcostal separate from the point of bifurcation. The median vein is three- 

 branched, with a medio-discal nervule running parallel with the superior 

 nervule from an oblique stalk. 



Head smooth, although hairy ; rather impacted. Without ocelli. Face 

 broad, rounded. Eyes rather small, not prominent. Antenna? setaceous, 

 pubescent beneath. Palpi exceeding the face by about one-third of their 

 length, ascending and rather porrected, tapering from the base to the tip and 

 rather thick ; basal joint very hairy ; middle joint tapering to the tip, with an 

 external ridge and squamose, but not hairy ; terminal joint distinct, rather 

 slender, squamose, rather less than one half as long as the middle joint. 

 Tongue stout, and one half as long as the body beneath. 



Thorax thick and tufted ; patagid with long elevated scales. All the femora 

 and tibiae clothed with long hairs. 



D. oculatana. Head, palpi and prothorax ochreous-fuscous. Thoracic 

 tuft ochreous. Fore'wings fuscous, varied with ochreous-yellow, with a small 

 subvitreous spot on the disk. The base of the wing and a band just internal 

 to the discal spot ochreous-yellow, each varied with fuscous stria?; and crossing 

 the middle of the nervules is another band of the same hue, slightly clouded 

 with fuscous above the middle, having a spot of the same hue behind it, 

 above the inner angle. Hind wings with a large subvitreus spot, produced 

 towards the external margin ; similar in color to the fore wings, but almost 

 reticulated with fuscous. 



The larva is quite as peculiar as the perfect insect. It is sluggish, with a 

 thick and much contracted body, and uniform in diameter. Head as broad 

 as the body, black. Color yellowish or orange yellow, thickly covered with 

 rows of oval, black tubercles each having a hair. The terminal extremity is 

 furnished with a black shield. The second segment (the one next the head) 

 is naked, softish and rather swollen. Length about six lines. The larva has 

 a disagreeable odor. It feeds on Eupatorium a g er at oides (white snake- 

 root) beginning on one side of a leaf to form a cone or cornet, cutting and 

 rolling the separated portion, as it increases in size, sometimes across the 

 entire leaf. At maturity it eats away the closed end of the cone and falling to the 

 earth forms on its surface a silken cocoon. There are two broods of larva, 

 one which matures in June, July, and another in the Fall, to appear as 

 imagos in April. I have never seen the imago on wing, but it will be found, 

 doubtless, wherever its food plant is distributed. The plant is a common one. 

 especially northward. The insect is rather rare in this region. 



Stigmonota Guenee. 



There is but little that is characteristic in the wing structure. In the fore 

 wings the costa is regularly arched, not broad at the base ; apex obtuse, hind 

 margin rounded, and slightly concave beneath the tip. The disk is rounded 

 behind, placed above the middle of the wing, with a small secondary cell and 

 discal fold distinct. In the hind wings the costal and subcostal veins arise 

 from a common stalk about the middle of the cell. The discal vein is rather 

 faint and slightly angulated in the middle, with a disco-central branch arising
