210 HAUSTKLLATA. — LEPIDOPTERA. 



Anterior wings dusky-blaclc, dusted througliout with ashy dots, and with a 

 faint whitish spot on the costa towards the apex : posterior deep fuscous. 



Rare : found occasionally in gardens within the metropolitan 



district in June. 



Sp. 20. lacteella. Alis anticis saturate fuscis, atro nubilosis, basi maculaque 

 posited costali capite thoraceque alhis. (Exp. Alar. 5 — 6 lin.) 



Ti. lacteella. Wien. Terz ?— An. lacteella. Steph. Catal. ii. 196. No. 7196. 



Anterior wings deep fuscous, with darker and rosy clouds and whitish dots, 

 the latter coalescing into streaks towards the hinder margin, and near the 

 apex of the costa expanded into a conspicuous spot, from which an irregular 

 blotch, varied with ash-colour and a slight rosy tinge, extends to the inner 

 margin ; the base of the wing, especially on the inner margin, is white, as 

 also the head, palpi, and thorax : posterior wings deep fuscous : legs annu- 

 lated with black and white. 

 Of this fine species I have seen only the pair which I possess, one 



of which was found at Dover in July, the other near London. 



Sp. 21. sarcitella. Alls anticis canescentibus nitiduUs nigra fuscoque nebulosis, 



capite thoraceque albis. (Exp. Alar. 6 — 9 lin.) 

 Ph. Ti. sarcitella. Linn^.—A.u. sarcitella. Steph. Catal. ii. 196. No. 719.5. 

 Anterior wings hoary, rather glossy, irregularly clouded with fuscous, and 



with a few indistinct black dots, disposed irregularly ; cilia lutescent, 



dusted with brown : posterior wings whitish, with lutescent cilia : head 



and thorax, with the extreme base of the wings, white. 

 Some examples are more suffused with dusky brown than others, and in some 



the ash-colour predominates. 

 Caterpillar inhabits woollens, &c. in houses, forming a case of its pabulum, in 



which it changes to pupa : the imago appears in the beginning of spring, 



and continues nearly throughout the year. 



Extremely abundant in houses, &c. throughout the metropolitan 

 district, and not uncommon in other parts of the country. 



Sp. 22. rusticella. Alis anticis angustis atris cinereo pulverulentis, posticis nigris.

Steph. Catal. ii. 196. No. 7194. 

 Anterior wings narrow, elongate, obtuse, deep black, slightly sprinkled with 



whitish or ashy atoms, especially towards the apex, and with a minute 



whitish dot on the costa behind the middle : posterior wings black, with 



brownish cilia. 



Not very common : taken occasionally, in June, in St. James''s 

 Park, and also near Darenth wood and in the New Forest.
