dark umber spot also occupies the centre of tlie same cell. Fringes long, same hue 

 as wings ; posterior margin darkly dotted, in the c? there is a line of dark shading 

 just in front of this margin, that is absent in the ? . Posterior-wings dark greyish- 

 brown, with long, somewhat paler, fringes. Length, 13 mm. 



Three specimens from the Shah Kuh mountains, 8,000 to 10,000 

 feet high. 



Hercynella margelana, n. sp. 



Fore-wings dirty ash-grey, with a black curved stripe between the base of the 

 wing and the centre, but rather nearer the latter ; a black spot near the costa beyond 

 the centre, followed by an oblique, curved, black stripe from the costa to the inner 

 margin, just beyond a small black dash near the anal angle. Hind margin darkly 

 dotted ; the extreme base of the wings is also blackish. The whole of the wing is 

 covered with rough, dark grey scales, which, in fresh specimens, are much lighter in 

 colour just in front of the posterior stripe, appearing as a paler band across the 

 wing. Fringes grey. Hind-wings brownish-grey, with a line of dark shading near 

 the posterior margin, which (margin) is finely bordered with black. Fringes pale 

 grey, with a dark dividing line. Length, 12^ to 13| mm. 



From Shah Kuh mountains, 8,000 to 10,000 feet high. 



This genus is very closely allied to Hercyna, but the pattern of 

 colouring is quite different ; the insects are (both species) only about 

 half the size of the species of that genus, they have none of the 

 lustrous appearance of the former, being rather of a dull rough sur- 

 face than otherwise, and the maxillary palpi are quite minute. The 

 palpi are also very stiflBy and closely haired up to the end of the 

 second joint, and the antennse are not ciliated.

CURATOR OF THE GROSVENOR MUSEUM, CHESTER. 



LECANOPSIS, Targioni-Tozzetti. 



This genus was established by Targioni-Tozzetti to receive his L. 

 rliizopUla. Subsequently Signoret (Essai, p. 285) included in it 

 Porphyrophora radicum-grnminis, Barensprung, and Coccus radicum- 

 graminis, Fonscolombe ; both, however, doubtfully. 



The chief generic characters given are — " Margin wide, witb a 

 deep anal cleft ; anal lobes obtuse, approximate ; antenna short, conical, 

 of six joints ; mentum ('Os') narrow ; legs short, stout ; tibise trun- 

 cate and anteriorly grooved ; tarsi ovate, acute." 



Although the species described below has eight joints to the
