tirely striped with pale yellow. A very broad pale yellow central band 
runs from the base of the wing, below the median and third inferior 
veins, to the internal angle, enclosing, near the external margin, a 
small black spot which indicates the obsolete furcation. On this me¬ 
dian band, in the terminal half of the wing, rests a series of similarly 
colored stripes resembling the letter K, with the straight stroke turned 
towards the base of the wing and the upper limb, attaining the exter¬ 
nal margin, reflexed to costa near the apex. A very broad straight 
pale yellow stripe extends from the costa to median vein, crossing the 
discal space, and a second, nearer the base of the wing, merely attains 
the sub-costal vein. Costa striped with pale yellow, fringes pale yel¬ 
low, internal margin showing a broad stripe of the same color narrowed 
towards internal angle. Posterior wings darker yellow with a broad 
semi-lunate discal spot and a very wide irregular black terminal band, 
narrowed at about the middle, not attaining the anal angle, joined to 
the base of the wing by a rather broad black straight streak • fringes 
pale yellow. 
Under surface of anterior wings blackish, showing the broad yellow 
bands of the upper surface; the veins in the terminal space striped 
with yellowish. Under surface of posterior wings resembling the upper 
surface. Disc of the thorax and tegulae deep black, bordered with pale 
yellow. Collar, and head between the eyes, pale yellow, immaculate; 
palpi black; eyes margined with black; antennae brownish, shortly 
bi-pectinate; legs dark brownish, anterior femora yellowish on the in¬

Allied to Arctia virginicula Kirby, which it exceeds in size ; the 
markings of the posterior wings are probably inconstant.
