TORTRICINA. 107 



6. Tanaceti, Sta. Alls anticis sub-nitidis, brunneis ; squamis ochra- 

 ceis irroratis; pone medium strigis obsoletis plumbeis; macula 

 margine dorsali trigona, dilution et indistincta ; posticis fusco- 

 griseis. tf Exp. al. 6^7 lin. 



Head olive-drab, palest behind and on the vertex. Face slightly 

 paler. Eyes black. Palpi longer than the head; at the base 

 ochreous ; the apex dusky brown. Antennae glossy, fuscous. Thorax 

 olive-drab. Patagia slightly paler. Anterior wings slightly glossy, 

 with a general irroration of ochreous scales on a dusky or pale umber 

 ground, and a somewhat paler indistinct trigonate blotch (sometimes 

 streaky) on the dorsal margin. On the costa are seven geminations, 

 not produced ; the interspaces fuscous ; in the apical region are faint 

 indications of lustrous streaks and spots. Apical scales umbreous. 

 Cilia very glossy, fuscous ; the bases broadly ochreous. Posterior 

 wings grey, with a fuscous tinge. Marginal scales umber, with pale 

 narrow bases. Cilia pale fuscous, with drab bases. Abdomen glossy 

 blackish ; the apex drab. $ Exp. al. 6-i 7 lin. 



First introduced into the British list by Mr. Stainton, in the 

 ( Entomologist's Annual' for 1857, p. 101, and is rare in 

 cabinets, although it is probably mixed up with some of the 

 closely-allied species. It mostly resembles D. simpliciana and 

 plumbagana. It differs from the former in the paler ground-colour 

 of the anterior wings, and in the presence of small slightly 

 metallic lustred streaks and markings, and the posterior wings are 

 much paler and fuscous grey. From plumbagana it is most diffi- 

 cult to distinguish : in fact, it appears to us as doubtful if it be 

 distinct from this latter species. 



Taken by Mr. Thompson, of Crewe, among Tanacetum 

 vulgare. 



7. plumbagana, Treit. Alis anticis brunneis, squamis ochraceis 

 irroratis ; strigulis ad costam albidis micantibus ; macula dorsali 

 indistincta subplumbea ; margine apicali punctis atris ; posticis 

 fuscis, vel brunneo-aureis. Exp. al. 6-7^ lin. 



Head olivaceous drab. Face slightly paler. Eyes purplish brown. 

 Palpi longer than the head. Antennas at the apex dusky, pale 

 ochreous at the base. Thorax olivaceous drab. Patagia slightly 

 paler, especially at the apex. Anterior wings dull pale umber, 

 thickly irrorated with bright ochreous scales, with shining drab 

 markings on the costa, and an indistinctly expressed triangulate, 

 slightly lustrous blotch upon the dorsal margin. Towards the base, 

 below the costal fold, are a few slightly shining leaden -lustred spots, 

 similar to the dorsal blotch. On the costa, before the middle, are two 

 faintly- coloured geminations, and five beyond, well denned, bright, 

 shining and produced into lustrous streaks : the first and second be-
