characters, comparing it here and there with sylcestraria, 

 may serve to impress it on the memory of the reader, though 

 doubtless the figure given at the commencement of this 

 volume will, should our artist be in his usual happy mood, 

 do more to give an idea of it, than words can possibly 

 convey. 



The fore wings are pointed, very much so in the female; 

 the hind wings are distinctly angulated at about the middle 

 of the hind margin ; the ground-colour of the fore wings is 

 a faint brownish-grey, with a dash of olive, and dusted all 

 over with innumerable black atoms, especially along the 

 costal nervure; cilia of the same colour, but without the 

 black atoms. All four wings, too, are bordered with a re- 

 markably fine continuous black line at the insertion of the 

 cilia (the corresponding border in syhestr^aria is dotted) ; the 

 lines, which are brownish, and four in number, are much less 

 wavy and irregular than those of sylvestra7na ; they are also 

 more conspicuous, straighter, and more obliquely placed. 

 On the disc of the hind wing in the male is a small black 

 dot, but none on the fore wing (as in sylvestraj-ia), and the 

 female is destitute of even this adornment — has no discal 

 dots at all in point of fact. 



The larva has been figured by Hiibner. 



Pempelia obductella, Fischer von Roslerstamm. 

 In the " Entomologist's Monthly Magazine," vol. vii. 

 p. 85, Mr. Meek records the capture of several examples of 

 this handsome Pempelia by Mr. Button near Gravesend. 

 It is one of those conspicuous insects that was almost certain 

 to occur here if only searched for with a moderate amount of 

 intelligence — the larva occurring on Origanum vulgare and 

 Mentha ar^vensis in May and June. The perfect insect 

 appears in July and August; it is allied to the group of
