AND THEIR TRANSFORMATIONS. 51 



Species 1. — Triphosa CERViNAXAf. — (Plate LXVIL, Fig. 1.) — Measures about 1|- inch in expanse ; wings <fn^t«. 

 greyish-brown, more or less pale, with some strigse or nearly obsolete fasoiolas towards the base, followed by two ' '' " 



deep brown narrow fasciaj across the middle of the wing, the outer one having the outer edge deeply bldentate ; 

 a black dot towards the costa is placed between these strigae, which are indeed sometimes almost confluent ; 

 there is also a slightly-defined, undulated, pale line, parallel with the apical margin ; hind wings slightly strigose, 

 the strigse corresponding with those of the fore wings. The caterpillar is greyish, with pale stripes on the sides, 

 the under side spotted with green, and the head brown ; it feeds on the barberry, and the moth appears in 

 April, frequenting gardens : it is, however, a rare species.

Species 2. — Triphosa dubitata^. — (Plate LXVIL, Fig. 2.) — Measures about li inch in expanse. Very 

 like the preceding, but the fore wings are very shining, and have a rich purplish tinge ; the strigffi nearly 

 arranged as in the former species, the two central fascije together forming a broad, unsolid bar, having a sharp 

 angle towards the costa on the outer edge, and having its hinder portion broader than in the preceding ; the cilia 

 of all the wings purplish, preceded by a black line. The caterpillar is green, with brown and pale lines and 

 streaks, and a yellow line on each side ; it feeds on the buckthorn, and the moth appears in May, and again in 

 August, frequenting gardens and woods, and is rather a common and widely-dispersed species.

Species 3. — Triphosa cinereata'' — (Plate LXVIL, Fig. 3.) — Measures from 1~ to li inch in expanse , 

 wings pale ashy, without any purple tinge ; the fore ones with a narrow brown bar at the base, and two 

 slender ones in the middle, forming a broad fascia, on the anterior margin of which is a black line, and towards 

 the apical margin an obscure whitish striga, and on the margin itself a slender dusky line ; hind wings pale 

 ashy and unspotted, and not strigose. Taken at Ripley, in July.

CAMPTOGRAMMA, Stephens. ACIDALIA, p., Treitschke. LARENTIA, p., Bdv. 

 The insect upon which Mr. Stephens has proposed the present genus is very closely allied to the last, having, 

 like it, the apical margin of the wings waved, and the disc very strigose : the antennae simple in both sexes, 

 and the wings placed in a triangle during repose ; but its palpi are rather long, porrected upwards into an 

 acute beak-like projection ; and its wings are destitute of gloss, and of a yellow colour. The caterpillar is 

 slender, not tuberculated, and with obscure spots and streaks. 



Species 1. — Camptogbamma bilineata '. — (Plate LXVIL, Fig. 1.) — Measures from I to 11 inch in 

 expanse ; wings yellow ; hind ones more orange ; all traversed by very numerous slender, darker, and lighter 

 strigae, two of which, of a white colour and very much scalloped, are placed before and beyond the middle 

 of the wing, the space between them forming a broad bar, generally darker coloured on the sides. The 

 caterpillar is greenish, with faint whitish streaks, which are sometimes wanting ; it feeds on Lychnis dioica. 

 This is one of our commonest carpet moths, occurring in hedges and woods at the end of June, and nearly 

 through the summer.
