138 TORTRICINA. 



8. Myrtillana, Treits. Alls anticis pallide griseis ; basi marginis 

 dorsalis macula magna angulata castanea ; postice fascia obliqua 

 bninnea strigata lineis atris longitudinalibus ; apice brunneo; 

 posticis griseis. $ Exp. al. 7 lin. 



Head and face varying from ochreous to chocolate-colour. Eyes 

 black. Palpi dull fuscous. Antennae fuscous, the basal joint clothed 

 beneath with shining drab scales. Thorax ochreous, or chocolate- 

 colour. Patagia ochreous. Anterior wings dirty-white, with cho- 

 colate and ferruginous-coloured markings. At the base, and extend- 

 ing to the middle of the dorsal margin, is a dull chocolate-coloured 

 mark ; its edge facing the costa, usually straight, and towards its 

 termination it becomes suddenly arched, and has its posterior edge 

 rounded. From the middle of the costa proceeds a pale brown angu- 

 lated indistinct fascia, which terminates on the dorsal margin within 

 the anal angle ; it is darkest at its origin, and in the middle are two 

 or more longitudinal marks or lines of chocolate colour, with an- 

 other, somewhat oval, towards its termination. The ocelloid patch is 

 roundish, and without markings. The costal portion of the wing is 

 clouded with pale brown, and a white line runs along and beyond 

 the costal border of the basal mark. Along the apical half of the 

 costa are four pale geminated streaks, with brown spaces between. 

 The apical spot is elongated. The pale portions of the wing, espe- 

 cially towards the apex, irrorated with dusky atoms, and the extreme 

 apical margin white. Apical scales (as well as the cilia) inter- 

 rupted below the apex by a brown streak running through, grey, 

 with the tips whitish. Cilia shining, pale straw-colour, becoming 

 greyish at, and iron-grey beyond, the anal angle. Posterior wings pale 

 fuscous, with a pearly lustre at the base. Marginal scales and cilia 

 shining, straw-colour, slightly grey towards the anal angle. Abdomen 

 fuscous, with a dull ochreous caudal tuft. $ Exp. al. 6-6^ lin. 



An uncommon species, and somewhat variable in size and 

 colour. In appearance comes nearest to Anch. Lundana, but is 

 larger and paler, and has the apex of the inner margin of the 

 basal patch suddenly arched, whereas in Lundana it is regularly 

 rounded. 



The imago appears in June, the males flying in the afternoon 

 among Vaccinium Myrtillus } the females at rest. It is confined 

 to the North of England, where its food-plant grows. It has 

 also been taken in Scotland. 



9. Lundana, Eabr. Alis anticis albidis; basi marginis dorsalis ma- 

 cula magna castanea, postice fulvis vel brunneis, striga angulata 

 caerulea ; posticis griseis. $ Exp. al. 7 lin. 



Head straw-colour, darker on the vertex. Pace straw-colour. 

 Eyes black, with a velvety appearance. Palpi straw-colour, pale 

 grey at the base beneath. Antenna dark grey above, paler beneath.
