Species II. — Cidaria fluctuata t". — (Plate LXIII., Figs. 12, 13.) — This extremely abundant species 

 measures from 1 to 1^^ inch in the expanse of the fore wings, which are of a dirty white, very much undulated 

 on the pale parts, with fine ashy strigK ; the base of the wing dark brown ; the centre with a large dark patch 

 extending from the costa about half way across the wing, where it terminates in a much narrower and paler 

 bar, which extends to the hind margin ; another dark smaller patch on the costa, near the apex, beneath which 

 is a double-toothed dusky small spot, forming part of the subapical striga ; the margin with black dots in pairs ; 

 the hind wings much waved with dirty white and pale gray strigas, and a central dot. There is much difference 

 in the intensity of the colour of the fore wings and their markings. The caterpillar is pale luteous or greenish, 

 with dark dots on the back ; it feeds on various garden plants, and the moth appears throughout the summer, 

 frequenting gardens, settling on walls, palings, &c., and entering houses.

Species 12. — Cidaria propugnata ''. — (Plate LXIII., Fig. 14.) — This pretty species measures from 10 



to 12 lines in expanse of the fore wings, which are of a dirty grayish white, marked at the base and across the 



middle with a broad clear reddish fascia, the inner margin of which is edged with a dark curved bar, and the 



outer margin is irregularly sinuated and black, preceded by two slender waved black lines ; the apical portion of 



the wing is more or less clouded, with whitish and grayish undulated strigse, and often with a darker patch on 



the costa ; the hind wings pale gray, with slight strigjB visible chiefly towards the anal margin. The antennae 



of the males are but slightly pectinated, whence Boisduval unites it with Munitata into a distinct section in this 



genus, from which Mr. Curtis has removed it. Found not uncommonly in woods, in various parts of tlie country, 



in July.
