26 TORTR1CIXA. 



This species was first eliminated by Mr. Stainton, who noticed 

 and described it in the ( Zoologist/ p. 1987. It is a common species 

 in gardens, and is in most cabinets : very like the ochreous 

 specimens of A. Betuletana, but distinguishable therefrom by 

 the roundish posterior margin of the basal cloud, and the more 

 umbreous and suffused colour of the cloud itself. Fig. 888 of 

 pi. 30 of Wood's ' Index Entomologicus ' represents this insect 

 very much more truthfully than the species it purports to be 

 (A. Cynosbatella}, from which it is easily separated by the absence 

 of the black dot in the middle of the posterior margin of the basal 

 cloud, and by the absence of the ocelloid patch at the anal angle. 



The imago appears from the middle of June to the beginning 

 of July, in rose-gardens. Like A. Capr&ana, it comes to light. 

 Not yet detected in Scotland, and only very sparingly in the 

 north of England. 



The larva feeds on the Rose, and is common in some places. 

 M. Guenee says of it, " Larva rosetarum pestis," showing, at 

 least, that on the Continent it is very abundant. 



6. Cynosbatella, Linn. Alis anticis albis; basi pone medium albo, 

 griseo, fusco, bnmneo, nigro caeruleoque variegatis ; in parte alba 

 medio, juxta marginem obscurum maculis duabus oblongis brun- 

 neis ; posticis fuscescentibus. <$ Exp. al. 7-10 lin. 



Head dusky brown, with a few grey scales. Face same colour as 

 the head, but somewhat paler below. Eyes black, slightly shining. 

 Palpi : above, at apex dusky brown ; drab at base, at sides, beneath 

 and between. Antennce fuscous, the basal joint above clothed with 

 dark brown scales, with its apex pale ; beneath usually with pale 

 drab shining scales. Thorax in front dull fuscous, spotted and 

 festooned with black, hoary grey behind ; the crest intense brown, 

 sometimes black. Patagia fuscous grey, striped with black towards 

 the base. Anterior wings dirty white. The costal and dorsal 

 margins maculated throughout with black. The basal or clouded 

 portion of the wing extends on the costa to the middle, and rather 

 more than two-thirds along the dorsal margin ; its posterior edge 

 undulated gently to the middle, then suddenly dilated into a sharp 

 angle, and from thence attaining the dorsal margin in an almost 

 perpendicular course. The basal patch and central fascia are much 

 angulated, and composed of rich golden brown, fuscous and black ; 

 the space between slightly paler, of a fuscous colour, and with an 

 oblong-oval mark, white at each end, on the fold towards the dorsal 

 margin. In the bay formed by the angle in the edge of the cloud 

 are two black spots, the uppermost largest and oval ; close to the 

 dorsal margin are one or two smaller spots ; the apical portion of the 

 wing clouded with grey, with a distinct eye-like spot at the apex, and 

 the margin sometimes with black limules. Apical scales shining, dark
