 the orbicular flattened, its lower edge often produced along median vein as a streak and connected with 

 reniform, which is large with the upper end angularly produced outwards; fringe mottled rufous and 

 mrieaala wnite ' hindwing fuscous, often with a reddish tinge; the ab. griseovariegata Goeze (= grisea Tult) (50 d) has the

 slightly dark-chequered. A mediterranean species, found in S. E. France, Piedmont, Corsica, S. Spain, 

 and Algeria. 



Sect. II. Antennae of £ almost simple. 



cymbalariae. 0. cymbalariae Hbn. (50 d). Forewing brownish fuscous, with an oblique postmedian fascia, slightly 



bent, of pale grey; veins black and thick towards termen; a diffuso black patch at end of cell; inner 

 line represented by black sagittae in the intervals; fringe conspicuously black and white; hindwing black, 

 with white fringe slightly chequered with black. Occurs on the Alps and Pyrenees, the mountains of Spain 

 and central Italy, and in Hungary and Bosnia.

streak, and subterminal space blackish; the veins black; the white ground colour shows as a streak in 

 lower half of cell, as a diffuse oblique fascia beyond cell, as a short, sometimes double, oblique streak 

 from apex, and as an edging of the veins at termen, especially between veins 8 and 4, and is ampler in 

 the $ than in the <J; orbicular stigma a black dot; reniform a black lunule, sometimes broken into 2 spots; 

 inner line shown by black wedge-shaped marks between veins; fringe mottled black and white; hindwing 

 deep velvety black with a large oval white space across end of cell. Lambessa, Algeria.
