10 HAUSTELLATA. — LEPIDOPTERA. 



the anterior wings are nearly of an uniform immaculate fuscous, without a 

 ferruginous or rufescent tinge. 

 All the varieties are destitute of those deep black longitudinal streaks which 

 form so conspicuous a character in the next species. 



An insect that occurs throughout the metropolitan district in the 

 greatest abundance, frequenting hedges, fields, and pastures, during 

 the month of August. " Bottisham." —Rev. L.Jeni^ns. " Kimpton."

(Exp. alar. 1 unc. 3 — 4. lin.) 

 No. I-niger. Haworth. — Ap. I-niger. Steph. Catal. pt. ji. p. 85. No. 6236. 



Extremely variable : head and thorax fuscous, the crest of the latter, in fine 

 specimens, rufescent at the apex : anterior wings pale griseous or fuscous, 

 with a darker central fascia, bounded by two pale strigse, which are united 

 near the inner margin by a black streak resembling the letter I ; in this the 

 stigmata are placed, the anterior wing elongate and obhque, with a black 

 margin, the posterior ochraceous or whitish, with a dark spot at the base, 

 and a duplex pale one at its apex : at the base of the wing are two short 

 black lineolae, one of which is on the inner margin ; the posterior margin is 

 clouded with fuscous ; behind are faintly indicated pale strigse : posterior 

 wings fuscous. 



The colour varies ; but all the specimens have the two basal and the central 

 black lineolae in the anterior wings : the posterior stigma is sometimes of a 

 snowy white, at others deep fuscous, and of aU intermediate shades. 



Also an insect that abounds in the London district, and I believe 

 throughout the surrounding neighbourhood, in the beginning of 

 August. " Bottisham." — Rev. L. Jenyns. " Marton Lodge." —

Head and thorax fuscous, sometimes with a rufescent tinge : anterior wings 

 ochraceous or rufescent, with a broad undefined fuscous patch on the costa, 

 in which the stigmata are placed ; these vary in colour, as in the two last 

 described, and their form is similar ; the ordinary strigje are more or less 

 evident, and each nervure, towards the hinder margin of the wing, has two 

 black spots, which form a kind of geminated striga ; the posterior margin of 

 the wing, excepting the apex, is irregularly fuscous, the latter being bounded 

 anteriorly by an undulated striga, which is more or less margined with fuscous : 

 the posterior wings are deep fuscous : abdomen the same.
