Sp. 3. aequa. Alls anticis griseo-cinereis, stigmatibus suhobliteratis, macule 

 apicis palUdiore ; posticis subalbidis tincturd violacei, niargine postice nigri- 

 cante. (Exp. alar. 1 unc. 10 lin. — 2 unc.) 



No. aequa. Hilbner? — Ag. sequa. Steph. Catal. part ii. p. 65. No. 6083. 



Thorax fuscescent: anterior wings clouded griseous-ash, with a double series of 

 black spots, as in the following insect ; between which are placed the usual 

 stigmata, which are nearly obliterated ; towards the apex is a paler or yellowish 

 spot : the posterior wings are dusky- white, tinged with violet, with the ner- 

 vures and the hinder margins, especially towards the anal angle, fuscous. 



Var. iS. Steph. Catal. I. c. Anterior wings pitchy-black or deep fuscous; the 

 posterior smoky-white, tinged with violet, with the nervures and hinder 

 margin as in Var. a, but nearly black. 



This rare species, as we learn from Lepidoptera Britannica, was 

 first detected in this country by Mr. Hatchett : it has since been 

 taken by Messrs. Raddon and Stone near London. The late 

 period of its appearance (September and October) is probably the 

 reason why so few examples have occurred : it is evidently very 

 variable, like the cognate species Corticea, Segetum, and sufFusa. 

 I possess a specimen captured in Hertfordshire. " Several ex- 

 amples taken near Epping in 1827, by me." — Mr. H. Doubleday. 



Sp. 4. Segetum. Alls anticis griseo-ferrugineis strigis undatis obscurioribus, 

 posticis albidis. (Exp, alar. 1 unc. 6—1 1 lin.) 



No. Segetum. Wiener Verz. — Ag. Segetum. Steph. Catal. part ii. p. 65. No. 

 6084, 



Head and thorax pale fuscous or griseous-brown : anterior wings the same, with 

 an abbreviated pale striga at the base, bounded on each side with dusky; 

 a similar undulated one before the stigmata, a third, more or less arcuated, 

 and varying considerably, being sometimes moniform (1), at others resembling 

 a comb with the pectinations outwards (2), occasionally placed in immediate 

 contact with the reniform stigma (3), at others at a distance (4); and finally, 

 towards the hinder margin, a waved band, composed of lunular pale spots, 

 on a darker ground: the abdomen pale ashy-brown; the posterior wings 

 white, with the nervures slightly fuscescent. The female (5) is usually darker, 

 and the posterior wings are of a bluish- white, with the hinder margins and 

 nervures dusky. 



Both sexes vary amazingly, and it is nearly impossible to obtain two specimens
