130 TORTRICINA. 



angle. Abdomen fuscous, the apex chocolate colour. Exp. al. 

 6|- lin. Markings somewhat more suffused than in the tf . 



This species does not vary. In general appearance it is very 

 much like S. ncevana, but the anterior wings are rather narrower. 



The imago appears commonly in the north of England, espe- 

 cially on the Moors round Sheffield. Stephens gives Yorkshire 

 and Whittlesea Mere as its localities. 



The larva feeds on Vacdnium Myrtillus. 



3. ustomaculana, Curt. Alis anticis cinereis, nitidis ; hasi macula 

 rhombea, medio fascia obliqua nebulisque ad apicem brunneis ; 

 macula margine dorsali caudata, grisea, fusco strigata ; costa strigis 

 griseis, geminatis ; posticis fuscis. <$ Exp. al. 5-i 6 lin. 



Head dusky drab, paler on the vertex. Pace pale drab. Eyes 

 black. Palpi as long as the head, dark fuscous, with the apices 

 whitish. Antennae dull, deep fuscous. Thorax and patagia umber, 

 the latter slightly paler. Anterior wings dull ; umber, with a large 

 white or grey blotch on the dorsal margin, and delicate violet mark- 

 ings towards the apex. At the base is a rhomboid, pale umber patch, 

 extending one-fourth along the costa, then proceeding with an in- 

 dented edge to the middle of the wing, and afterwards returning to 

 the base with a rounded outline, without touching the dorsal margin, 

 towards which its colour is darkest. At the middle of the costa 

 commences an umber fascia, which attains the anal angle ; it is 

 narrow at its origin and termination, and dilates in the middle. 

 Before the middle of the costa are two faint geminated streaks, and 

 five others more defined beyond, with umber interspaces. The apical 

 spot distinct, with a white streak below : a pale umber cloud below 

 the apex, more or less produced to the anal angle, and encloses a pale 

 oval spot. The dorsal blotch is obtusely triangular, with the apex 

 rounded, and its anterior portion continued narrowly to the base ; of 

 silvery- white colour with dusky freckles, and wedge-shaped, black 

 markings along the margin ; the pale portions of the wing freckled 

 and of a delicate pale violet tinge. Apical scales pale uraber, with 

 lighter bases and interrupted below the apex by a white streak. 

 Cilia smoky brown at the apex, becoming paler at the anal angle. 

 Posterior wings and marginal scales fuscous, the latter with the bases 

 paler. Cilia fuscous grey. Abdomen pale fuscous, the caudal tuft 

 drab. 5 Exp. al. 6^- lin. The basal patch of the anterior wings 

 less distinct than in the tf . 



A rather common insect in the North of England and in Scot- 

 land. 



The imago appears in June, and was first captured by Mr. John 

 Curtis at the Black Forest, Loch Rannock . it has since turned 

 up wherever the food-plant of the larva abounds.
