and the liind-margin, a faint square spot near the margin, and another at the anal 

 angle, both grey, only visible in certain lights. Hind-wings and all the cilia, black. 



The "scorched" appearance is produced by a delicate marbliug 

 of chestnut scales, and is very characteristic of this species, as dis- 

 tinguished from that found among Stacliys paJustris. 



Wood's figure of ustulana (912) is more of the shape of the latter, 

 but has a distinct round black spot in the sub-apical pale band, which 

 does not belong to either, and seems to render it unrecognisable. 



Under these circumstances, I think it will prevent confusion if 

 we adopt the name earhonana of Doubleday's list for the fen species. 

 This name is not, as far as I know, supported by any figure or 

 description, but it has been very generally used in connection with 

 these (combined) species, and may very well (and extremely suitably) 

 be adopted for that now recognised and separated for, I believe, the 

 first time. It may be described as follows : — 



Carhonana (Dbld. list). Head black. Palpi and antennae hoary grey, tliorax 

 dark grey, foro-wings rather narrow, with costal margin but little arched, and the 

 hinder portion of the wing somewhat squared. Ground colour varying from very 

 smoky whitish to blue-grey, basal blotch large, blackish, with indented, somewhat 

 perpendicular, margin ; central fascia rather narrow, perpendicular, deep black with 

 the margins indented and irregular, often cloudy ; just beyond and parallel with it is 

 an elongated black blotch, and another merging into an obscure triangle on the anal 

 angle ; hind-margin and apex irregularly streaked with black ; on the costa a few 

 irregular black dots, from which run delicate lines into the paler space. Cilia dark 

 grey, with a black line at their base. Ilind-wings dark grey, cilia paler. 



Among Stacfiys palustris in fens and marshes in June, the larva 

 feeding in the stems in the autumn. 



It is a very obscure smoky-looking species, distinguished from 

 fuligana by its longer, more sharply squared, fore-wings, and the 

 absence of the " scorched " markings ; and from marginana, which it 

 nearly approaches in shape and size, by its dark ground colour and 

 ill-defined smoky markings, which also are differently placed, and by 

 the dark hind-wings in both sexes.

NOTES ON THE OVA AND LAEV^ OF BANKIA AROENTULA. 

 BY JOHN BEOWN. 



Chippenham Fen, Cambridgeshire, is one of our best localities for 

 B. argentula ; it occurs abundantly there the whole of the month of 

 June. The date of my visit to this place was upon the ]Oth of June, 

 1884, for this species in particular, great numbers of which were taken
