Or. bistrigana. Sfepk. Catal. ii. 162. No. 7013. 



Anterior wings brown, with two pale yellowish straight fascise, one before, 

 the other rather behind, the middle, and numerous silvery spots, some of 

 which are disposed in interrupted streaks; cilia yellowish, with a brown 

 cloud near the anal angle: posterior wings fuscous; cilia flavescent. 



Also extremely rare : I have seen three specimens only, which 

 were found in the vicinity of London, several years since, in the 

 summer, by ]\Ir. Stone. 



C. Anterior wings rounded on the hinder margin ; the disc with large pale 



spots placed diagonally, so as to produce a tessellated appearance : — 



Phelonia, Uubner. 



Sp. 5. tesserana. Alis anticis aurantiaco-fulvis, maculis quinque Jlavo-aureis 

 tessellafim positis, strigisque argenteis Jlexuosis, posticisfuscis' (Exp. Alar. 

 6—7 lin.) 



To. tesserana. Wien. Verz. — Ar. tesserana. Steph. Catal. ii. 190. No. 7124. 



Anterior wings of a tawny-orange, with five large approximating spots, 

 placed two towards the middle of the costa, two others on the inner margin, 

 hut not opposite, and the fifth on the hinder margin ; these spots vary in 

 colour, being sometimes all pale yellow, at others whitish ; occasionally the 

 two costal ones and that on the hinder margin are yellow, with the two 

 others whitish ; again other specimens have all but the two costal spots 

 obliterated: the colour of the wing also varies, being occasionally of a 

 tawny-red, or yellowish ; but in all there are some fine flexuous silvery 

 stripes, arising between the spots : posterior wings fuscous : head and thorax 

 tawny. 



Taken abundantly in June on the Downs near Brighton ; also near 

 Dover, in Hants, &c., and occasionally near Croydon and Hertford, 

 but rather a scarce species.

 que Jlavis, posticis nigris. (Exp. Alar. 7 — 8 lin.)

Anterior wings fulvous, with about five interrupted silvery stripes, a broad 

 yellow fascia at the base, two spots of similar colour on the costa, and two 

 opposite, and a larger transverse one on the hinder margin : posterior wings 

 black. 

 Found in June, not very uncommonly, on the Downs near Albury 



in Surrey, about Newland's Corner : it has also been taken in May 



at Coombe wood.
