148 TORTRICINA. 



discoidal cell extends two -thirds the length of the wing. Posterior 

 wings; apex acute, apical margin concave, basal angle produced. 

 Abdomen slender and tufted at the apex in the rf , slender and ob- 

 tuse in the $ 



The only species known in this genus bears some resemblance 

 in shape to the preceding, but is prettily marked with various 

 colours and metallic lustred spots. Structurally it differs from 

 Bactra in its broader and shorter anterior wings, and their less 

 acute apex. 



1. Conwayana, Fab. Alis anticis flavis, medio nubilis fulvis, ad apicem 

 saturate branneis, argenteo obsolete punctato-strigatis ; posticis 

 fusco-griseis, apice saturatioribus. $ Exp. al. 5^-6^ lin. 



Head pale ochreous, sometimes slightly fuscous behind. Face pale 

 ochreous above, paler below. Eyes black. Palpi twice the length 

 of the head, whitish above, between and beneath, dusky at the sides. 

 Antennae above pale ochreous, alternated with brown, except a few 

 joints at the base ; beneath fuscous, the basal joint ochreous or straw- 

 coloured. Thorax ochreous, dusky in front, and with a dusky trans- 

 verse band across the disk. Patagia ochreous, sometimes speckled 

 with dusky scales. Anterior wings bright yellow, the costal and dorsal 

 margins maculated with black ; the base is clouded with ochreous, 

 with one or two blackish streaks followed by a ferruginous, curved 

 fascia before the middle ; beyond the middle of the wing is a ferru- 

 ginous cloud, uniting with the basal fascia, thus leaving a pale 

 space on the costa (this sometimes wanting) with another on the dorsal 

 margin, the former being irregularly trigonate, the latter roundish 

 (very frequently the apical half is wholly suffused with dark or casta- 

 neous brown), at the subapical portion of the costa are one or two 

 yellow marks; the rounded dorsal mark is palest towards the base, and 

 veiy frequently it has one or more blackish streaks running through it. 

 The disk of the wing is studded with small patches of lustrous blue 

 scales, bright in fresh specimens, but they soon become abraded. 

 Apical scales orange ; cilia slightly paler, both becoming grey at the 

 anal angle. Posterior wings deep fuscous, paler at the base. Mar- 

 ginal scales deep fuscous, with pale bases. Cilia grey at the apex 

 and towards the anal angle, white between. Abdomen deep fuscous. 

 $ Exp. al. 5^-7^ lin. In general colour paler than the <$ . 



A common insect, and varies considerably in the colour and 

 intensity of its markings ; the ordinary form is that as above de- 

 scribed, but there are two varieties, A. Hoffmanseggiana and A. 

 subaurantiana. 



A. Hoffmanseggiana differs from the type in being much darker, 

 and in having the anterior wings suffused, but it is not of very 

 frequent occurrence.
