a considerable number of waved transverse pale shining lines ns far as the 

 middle, beyond which are two more compound ones, with several shorter 

 on the costa, and a row of spots of the same colour at the base of the cilia.- 

 abdomen ochreous at the apex. 



Similar to O. nubilana, HUb. in size and colour, but the 

 superior wings are a little less obtuse ; their colour is very 

 different, and the bar across the middle, formed by the waved 

 lines, is narrower and more irregular. 



I believe my specimen was taken by the late Mr. Blunt. 



7. O. alternana Curtis' s Guide. 



Shining ochreous-grey : thorax and superior wings freckled with black, 

 the latter with 9 pair of pale spots on the costa, the base rather darker, 

 the black spots forming irregular and broken transverse lines ; a blackish 

 fascia across the centre freckled with a few pale scales, having a longitu- 

 dinal pale line across the middle ; the apex rather dark ash colour : cilia 

 with a black spot at the tip and middle : inferior wings fuscous. 



Smaller than O. micana, Hiib., to which it is most nearly 

 allied ; the name is given from the alternate dark and pale 

 spaces on the upper wings. 



Var. /3 larger: superior wings more ochreous, the markings 

 brown and less distinct, the cilia immaculate. 



On the 14th of July Mr. Dale and myself discovered this 

 moth amongst heath in the Black-wood, Loch Rannoch. 



8. O. gramineana Curtis's Guide. 



Head thorax and superior wings ferruginous brown; the latter with 7 or 

 8 pairs of whitish spots on the costa, with a somewhat silvery sinuated 

 fascia, leaving a dark space at the base; apical portion of the same pale 

 colour, leaving a dark and very sinuated fascia across the middle; the apex, 

 3 triangular spots on the costa, and an oblique lobe-shaped mark, rising 

 from the posterior margin, and another near that angle, ferruginous brown.- 

 inferior wings fuscous. 



Most allied to and the size of O. cespitajia, Hiib. I took 

 it the end of June, on grassy slopes ascending Arthur's Seat. 



9. O. cespitana Hub. Tort. 244 & 245. 1 8th June, heath, 



side of a hill, Ambleside; and 14th July amongst fir-

 north side near the top of Schichallien upon the turf 

 amongst the rocks. 



1 1 . O. Turionella Lin?i. — Curt. Brit. Ent.pl. 364. Bred from 



the caterpillars which fed on the shoots of the Scotch 

 fir, by Mr. Wigham of Norwich. The larva and pupa 

 are copied from Hlibner, but I am not certain whether 

 they belong to this species or to T. Resinella L. 



12. O. gemmviUQi Huh. Tort. 269. — e. July and August, pales, 



Regent's Park, and grass. Birch-wood.
