Uniform pale straw yellow. Base of the head, base of the fore legs 

 and tarsi blackish. Very woolly; on the wings the long woolly scales 

 are arranged into transverse waved ridges, which become longitudinal

 States with which it has been confounded, not only in its smaller size 

 and paler colors, but the costa of the forewings is straighter, the apex 

 is much more pointed, and the outer margin is more oblii^ue. The 

 secondaries are likewise more produced. The L. opercularis wants, 

 moreover, the distinct brown discoloration below the black costal border. 



Among thirteen specimens reared from the blackberry bush by 3Ir. 

 Shurtlefl". the males are more deeply colored than the other sex. The 

 individuals varied but slightly in having the brown middle portion of 

 the wing more or less distinctly separated from the dark costal margin. 



The larvfe were found feeding upon Rubus vil/osus early in Septem- 

 ber. The following description is taken from specimens preserved in 

 alcohol, and is deficient in the colors of the hairs. Body very short 

 and thick, soft and fleshy. Head very retractile. The mouth-parts 

 are somewhat produced ; the labrum and maxillae are long and large, 

 and the lobes of the labrum are larger than usual. The epimeral ridge 

 along the side of the body is large and prominent, and on the protho- 

 racic ring is much elongated, while the upper fissured edge of the ring is
