Species 3. — Hemithea cythisaria ^. — (Plate LX., Figs. 6, 7-) — This species measures about 1^ inch in 



the expanse, its wings being of a pale dull green colour (subject to fade), with two darker green flexuous strigse, 



between which is a dark lunule, and a submarginal, paler, undulated striga, often obsolete, which also extends

 The antennas are bipectinated in the males, but slender and setaceous in the females ; the spiral tongue long ; 

 palpi short, and wings slightly dentated, and extended horizontally in repose ; the abdomen tufted at the 

 extremity in the males, but acute at the tip in the females ; the larva are ten-footed, and somewhat tuberculated. 

 They feed for the most part on lichens, and the chrysalis is enclosed in a cocoon amongst leaves. 



Species 1. — Cleora bajularia b. — (Plate LX., Figs. 8,9.) — This species measures li inch in expanse; 

 the wings are of a delicate pale green, with the costa of the fore wings pale ; a slender, curved, pale, whitish 

 striga near the base, and another submarginal arising from a large pale blotch at the anal angle, with a fulvous 

 centre ; the hind wings vdth the margin irregularly pale, with a dark undulating line, and each angle with a 

 patch of the same colour ; cilia white, spotted with brown. The caterpillar is grayish brovyn, and tubercular ; 

 it feeds on the oak, and the moth appears in oak woods in July, but is not abundant.

 striga near the base ; a broad, ill-defined fascia in the middle, open towards the costa, and followed by several 



* Mr. Curtis appears from his enumeration of the species which he regarded as referable to this genus, to have intended a group with simple 

 antennse, but he unfortunately drew his characters from a species which possesses pectinated antennae, and does not associate with the others.
