108 TORTRICINA. 



yond the middle unite, and are continued obliquely to the ocelloid 

 patch, which is of the same lustrous colour, and encloses some um- 

 breous atoms ; on the margin beyond the ocelloid patch is a row of 

 black dots, varying in number from three to five, and differing in 

 size. Apical scales very shining, deep cinereous. Cilia also very 

 shining, and boldly expressed ; their bases pale ochreous, and the 

 tips broadly deep cinereous, paler at the anal angle. Posterior wings 

 shining fuscous, with a golden-brown tinge, paler at the base, and 

 the extreme margin pale ochreous. Marginal scales deep cinereous. 

 Cilia drab, broadly pale, cinereous in the middle. $ Exp. al. 6-7^ 

 lin. Marked like the <$ , but the colours more distinct, the umbreous 

 ground-colour appearing in patches. 



Not a very common species, nor does it appear liable to great 

 variation. It very closely resembles D. Tanaceti, but the poste- 

 rior wings in that species are grey, not fuscous, and the anterior 

 wings have their markings less 'distinctly defined. It also re- 

 sembles D. acuminatana, but may be separated from it by the 

 anal angle of the anterior wings being more produced. 



The imago appears in June, and is generally distributed 

 throughout the country ; it occurs also in Ireland. 



8. acuminatana, Zell. Alis anticis nitidis, brunneis vel olivaceo- 

 brunneis ; squamis ochraceis irroratis ; apice acuminate ; macula 

 magna margine dorsali, triangulari et dilution ; margine apicali 

 punctis atris ; posticis nitidis, fusco-griseis. 3 Exp. al. 5-6 lin. 



Head and face dusky drab. Eyes black. Palpi longer than the 

 head; above dusky; sides dusky, with an ochreous patch at the 

 base ; beneath drab ; between shining drab. Antenna fuscous. 

 Thorax and patagia dusky brown. Anterior wings somewhat acu- 

 minate, glossy pale umber or olive-brown, with a general irroration 

 of ochreous scales, and a large slightly paler streaky triangulate 

 ' curved blotch in the dorsal margin ; on the costa are seven gemina- 

 tions, sometimes obliquely produced into slightly lustrous streaks ; 

 at the apical margin is a row of black dots. Apical scales umbreous. 

 Cilia very glossy, paler, with broad yellow bases. Posterior wings 

 glossy grey, with a slight fuscous tinge, most visible at the apex, and 

 a greenish-grey iridescence. Marginal scales fuscous, with drab bases. 

 Cilia pale drab ; the apices grey. Abdomen glossy, varying from 

 fuscous to blackish ; the apex drab. $ Exp. al. 5-5^ lin. Anterior 

 wings darker ; posterior wings more uniformly grey than in the J - 



This is a common insect in some places, very like D. simpli- 

 ciana, senectana, Tanaceti, saturnana, and plumbagana ; but it is 

 smaller in size, and distinguished by the more acute apex of the 

 anterior wings. 



The imago appears in August, in grassy places and among
