Cotypes in U. S. Nat. Mus. 



Oydia cupressana sp. nov. 



Expanse 14-16 mm. 



Head : dark greenish-brown, scales tipped with cinereous on tlie face the latter 

 predominates, making face lighter, scales of head form semi-circular tuft above 

 eyes, meeting above as a slight crest. Palpi very short, tip of outer joint scarcely 

 projected beyond face, scales of second joint rather closely compressed, tuft small, 

 colored same as face, outer joint black, bare, short, blunt. Thorax smooth, shin- 

 ing fuscous, patagia same, but scales shading into whitish at outer ends, neither 

 irrorated with lighter specks like head. Abdomen and legs above shining fus- 

 cous, paler below, anal tuft tinged with ochreous. 



Forewing: dark chocolate-brown, very finely irrorated with transverse lines, 

 pale yellowish-green scales beyond basal area and crossed by five rather broad 

 metallic lines, of a silvery-salmon hue; only the first pair of lines in middle of 

 wing are continuous from costa to dorsal margin, the third ends just before 

 reaching dorsal margin, the fifth is but little more than a costal streak ending at 

 vein 8, the outer line before the outer margin is divided in three parts by two 

 evenly spaced interruptions. A small metallic dot below costa between fifth line 

 and apex. On the extreme costa the metallic scales are replaced by yellowish- 

 green. The metallic lines are partly bound by black, notably: before the first, 

 beyond the upper third of the streak, which black streak follows along costa to 

 third line and down its inner side to top of cell ; the lower half of this third line 

 is defined on its inner edge by black, the black line at its upper end turns out- 

 wards, at right angle, cutting through the metallic line, and continues to the 

 inner edge of the fifth metallic line, which it defines for the length of its middle 

 section ; in some specimens the horizontal black line is not continuous, and the 

 line before the fifth metallic is also broken into two to four short horizontal 

 dashes. Black also outwardly defines the fourth short line. The basal area is 

 ground color, slightly shining, lightly and sparsely dusted with yellow-green 

 atoms, it occupies nearly a third of the wing on dorsal margin, a quarter on costa, 

 its outer margin oblique for two-thirds of its length, then vertical to dorsum. 

 The metallic lines are nearly parallel to each other, the space between first and 

 second is widest, the ground color between these two lines is also more heavily 

 overlaid, with the pale atoms, the same is the case between third and fourth, and 

 between fifth and apex ; making an effect of three paler fasciae, separated by two 

 narrower darker fascise. Cilia luteous-metallic, preceded by a narrow brown- 

 black line, the latter interrupted a third below apex by a small square yellowish- 

 green spot. 



Hindwing: deep smoky brown, cilia white, preceded by a brown line, and this 

 by a faint narrow pale line ; long hairs near base on veins 1 and lower median 

 vein white. 



Underside both wings: dull brown ; underside forewing: costa marked with
