26 HAUSTELLATA. — LEPIDOPTERA. 



wlien I let go the remainder, with one exception, to the number of 

 eighteen ; on the 25 th of that month, the one before alluded to 

 produced a very fine female specimen ; and on the same evening, 

 the windows being open, my room was filled with a swarm of 

 moths ; on the capture of which, I found them to be the identical 

 eighteen which I had let go, all of them males, and not a single 

 specimen of any other insect amongst them." " York." — W. C.

Head and thorax brown, varied with white: antennae luteous: anterior wings 

 fuscous, with black undulated strigae, and varied with white, with a distinct, 

 oblique, and irregular fascia of that colour in the middle towards the costa, 

 and a rounded somewhat trilobed patch of the same at the apex, from the 

 latter of which a dentated white striga arises and passes to the anal angle ; 

 between the stigmata is an obhque brown Une and two parallel black ones, 

 forming a character somewhat resembling the letter N ; the anterior stigma 

 is pure white, and forms part of the central fascia, the posterior is clouded 

 with fuscous in the centre : posterior wings fuscous, with the base paler. 



Var. (S. Steph. Catal. I. c. — Ph. No. X-scriptum. Sowerby Brit. M. pi. 55. — 

 Anterior wings much darker, especially at the apex, the trilobate white spot 

 almost obliterated, the pale dentated posterior striga alone conspicuous; base 

 of the wing nearly as in var. a,; the parallel black Unes between the stigmata 

 united in the centre, and forming the letter X, whence the name above 

 employed by Sowerby to designate the very specimen from which this 

 description is di-awn up. 



Caterpillar grey, with brownish dorsal spots : it feeds on the Lychnis dioica : 

 the imago appears in June, and frequents the borders of woods. 



Not common, but more abundant in some years than others, 

 though previously to 1818 few cabinets contained more than a 

 solitary specimen : since that period many specimens have been 

 taken at Darenth-wood, where I have also captured it, and near 

 Brighton.
