 expanse ; the wings are of a luteous bufif colour ; the costa and apical margin of the fore ones varied with brown, 

 and with a slender black waved, very oblique line beyond a central dot, followed by a dark cloud ; the hind

 The antennse of the males in this genus, as restricted by our English authors, are pilose beneath, instead of 

 pectinated, as in the last genus ; the palpi short and horizontal, with the terminal joint minute ; the hind wings 

 with the margin dentated, and the disc of all the wings pale and much freckled ; the fore tibia are furnished with 

 a broad spur in the middle.

^■^ 11 inch in expanse; the wings are pale ashy white varied with brown, a duplicated brown bar towards the base, 



followed by an indistinct central line, and beyond the middle are two curved pale lines, the first generally edged with 

 black, and the second dentated, and between these is a dark quadrate patch in the middle; the hind wings less 

 varied with brown, but with two dark strigse towards the anal margin, and a dark central lunular spot. Birch

Species 2. — Tephrosia abietaria". — (Plate LXI., Fig. 3, and Plate LX., fig. 22, larva.) — This species 

 measures rather more than 1^ inch in expanse ; the wings are gray and atomose, with denticulated more or less 

 distinct dusky, or occasionally ferruginous striga running across all the wings ; the chief vein of the fore wings 

 dotted with black, and a dusky shade in the place of the quadrate patch near the apical margin of the fore wings, 

 the basal strigse of the fore wings also often obsolete. Found in woods in March and April, but not common. 

 The caterpillar of Hiibner's Abietaria (which may possibly not be congenerous with our insect) is rusty brown, 

 with the front of the body darkest, the hinder segments more straw-coloured, and varied with slender dark lines 

 and marks.
