CHEIMATOPHILA, Stephens. 

 The narrow glossy wings of this genus with the costa straight, the apical angle slightly falcate, the disc of a 

 rich purplish-chestnut hue with pale whitish, ill-defined, slanting markings : the palpi porrected and very 

 squamose ; the apical joint being scarcely visible : the head tufted in front, and the autumnal and hyemal period 

 of the species, are the chief characters by which it is distinguished from its relations. 



Species 1. — Cheimatophila castaneana) — (Plate XCVIII., Figs. 1,2) — Measures from 7 to 9 lines 

 in expanse ; fore wings of a rich purplish-chestnut colour, much mottled with ashy-white clouds, arranged for 

 the most part, in very oblique stripes, forming, as it were, two very ill-defined clouded bars across the middle of 

 the wings, behind which is a pale streak near the inner margin, and within the apical margin of the wing is 

 another patch of the same pale colour : hind wings pale-brownish, very faintly reticulated towards the outer 

 angle ; these spots are very variable, and are sometimes almost obliterated. Taken in the New and other 

 Forests late in the autumn and winter.

ARGYROTOZA, Stephens. 

 The palpi in this genus are considerably porrected in front of the head and densely squamose, the terminal 

 joint being nearly concealed ; the antennae of the males are scarcely pubescent ; the head strongly tufted in 

 front ; the fore wings elongate-triangular, truncate along the apical margin, and straight along the costa ; the 

 disc being yellow or reddish, and ornamented with silvery curved lines. 



Species 1. — Argyrotoza Bergmanniana'^ — (Plate XCVIII., Fig. 3) — Measures about ^ an inch in 

 expanse ; fore wings rich golden yellow clouded with orange, and very obscurely reticulated ; with four purplish 

 brown, rather slender fasciae, which are ornamented with silvery scales, the first near the base, the second before 

 the middle, the third rising on the costa rather beyond the middle and extending to the anal angle, emitting a 

 silvery branch which runs obliquely to the inner margin ; the apical margin also similarly ornamented ; fringe 

 pale-yellow ; hind wings blackish brown : head and thorax canary-coloured. This is a very common species, 

 the caterpillar doing much injury in gardens by devouring the young buds of roses as described in my article on 

 this species, in the late Mr. Loudon's " Gardeners' Magazine," Vol. xiii., p. 38.5.
