3G [February, 



represented by tlie original type specimen, I found in his series of 

 *' Tenebrella, Hiib.," other examples of unicoloi^ella mixed with those 

 of the true tenehrella. 



A. unicoJorella is very widely distributed in Britain, and I have 

 myself identified specimens of it from Argyll (Oban, A. F. Griffith), 

 Lancashire (Grange, H. T. Stainton), Herefordshire (Tarrington and 

 district, J. II. Wood), Kent (Dartford Heath, H. T. Stainton ; West 

 AVickham, J. W. Douglas), Surrey (Mickleham, J. W. Doiujlas), and 

 Sussex (Abbotts Wood and Steyning, W. H. B. Fletcher). Although 

 one moth, erroneously supposed to be immacidatella, was bred by 

 Threlfall from among roots of sea-plantain (Eat. Mo. Mag,, xv, 89), 

 and another standing in Stainton's continental collection and wrongly 

 identified by him as immaculatella, was bred from Lotus corniciilatus, 

 nothing is yet known about the larva. Mr. Fletcher, who has taken 

 the imago in such very dissimilar spots as the rides of a large wood on 

 stiff clay soil, and the sunny bank inside a chalk-pit in the open, 

 suggests that Lotus, or some near ally, may eventually prove to be 

 the food-plant. 



1 know no reason for supposing that this species is double- 

 brooded. I have included, among the months for the imago. May, 

 because Sorhagen (I. c.) includes it, and August, because Douglas 

 took his type-specimen of immaculatella then, but all the other 

 captures known to me, whether in Britain or on the continent, have 

 been made in June and July. It therefore seems probable that the 

 May and August specimens are merely precocious and late individuals.

[Aeistotelia tenebrella, Hb. 



n. syn. = Butalis bvffonella, Mill, {teste Ragonot, MS.). 



In the late Monsieur Ragonot's copy of Staudinger's Catalog 

 (which we have been enabled to study through the kindness of 

 Madame Eagonot), the following note occurs under Monochroa tene- 

 hrella, Hb. : — " = Butalis hvffonella. Mill. Cat., 361, vu type Cannes." 



The synonymy should, therefore, stand thus: —
