TORTRICINA. 



137 



pi. 32, fig. 959 ; variable in size and colour. It is allied to 

 Anch. diminutana and Anch. uncana. From the former it is di- 

 stinguished by its larger size and the double arch in the longi- 

 tudinal undulating line across the wings. It is smaller and paler 

 coloured than A. uncana } and further distinguished from it by the 

 pale, and less distinctly geminated costa. 



The imago appears in June and July, and is distributed 

 throughout the country; the recorded localities are around 

 London and near Birmingham ; it has also been captured near 

 Orrniston in East Lothian, N. B. 



7. uncana, Hub. Alis anticis bnumeis ; arcubus duobus cinereis ni- 

 tidis ad marginem dorsalem ; posticis griseo fuscis. $ Exp, al. 9 lin. 



Head dull fuscous, or griseous. Face slightly paler. Eyes black. 

 Palpi above and at the sides smoky grey, paler beneath and between. 

 AntennaB dark fuscous, paler beneath. Thorax dull fuscous. Pa- 

 tagia at the base dull fuscous, the tips paler and shining. Anterior 

 wings grey, with chocolate-brown markings ; near the base, on the 

 dorsal margin, commences an undulating line which divides the sur- 

 face of the wing into two parts, and forms two arches in its course 

 to the apical margin : that portion towards the costa is chocolate - 

 coloured near the undulating line, becoming paler at the margin ; the 

 dorsal portion is grey, thickly clouded with fuscous. The roundish 

 mark at the anal angle is the ocelloid patch, and at its inner portion 

 is a suffused, pale, curved, chocolate-brown streak ; from the middle 

 of the costa is a very oblique, truncated fascia, of chocolate-brown, 

 extending to the ocelloid patch. The costa is marked throughout 

 with pale geminated streaks, those towards the apex most distinct, 

 lustrous, and produced ; the apical spot distinct, and below it is a 

 whitish patch, with a black streak running through it. The costal 

 portion of the wing, before the truncated fascia, with a leaden tinge, 

 beyond it pale chestnut-brown ; extreme apical margin edged with 

 brown. Apical scales fuscous, with drab tips. Cilia fuscous, with 

 paler tips, becoming lighter coloured towards the anal angle. Poste- 

 rior wings pale fuscous, straw-colour at the apex. Marginal scales 

 slightly straw-colour. Cilia very pale fuscous. Abdomen fuscous ; 

 the caudal tuft ochreous. $ Exp. al. 9-9^ lin. 



By no means common. It varies in size and in the intensity 

 of its markings. Most closely allied to Anch. biarcuana y but its 

 dark and regularly geminated costal margin distinguishes it from 

 that species. 



The imago appears in May and June in heathy places. It 

 occurs at Darenth, Coombe, and West Wickham Woods, and 

 other localities around London ; also in the North of England, 

 and at Belfast in Ireland.
