two species I have included in Trachea, would not as well as- 

 sociate with the former ; for these gi'oups of Lepidoptera are 

 so destitute of characters, that they are generally arbitrary. 



1. T. Atriplicis Li7in. — Curt. Brit. Ent. jpl. 431. 



This is a rare moth in Britain ; but many years since it used 

 to be taken near London; it has subsequently been observed 

 by Dr. Leach near Cheltenham, and by Dr. iSkrimshire at Wis- 

 beach in Cambridgeshire. The time of its appearance is stated 

 to be June and September in gardens, hedges, and on walls. 



The caterpillars are supposed to vary considerably, for 

 Roesel has represented one in his first volume, pi. 31, of a 

 rosy or flesh colour, whilst Hiibner's, from which our figure 

 is copied, is green and black above : they feed on the Atrijdex 

 hortensis, Rtimcx occtosa (pi. 396.), Polygormm Persicaria, 

 (pi. 284.), and P. Hijdropiper. 



2. T. protea Hilb. — Och.— Goda 6. fl. 89./ 2, 3. — nebulosa 



Bork. — Seladonia Haw. not of Fab. 



Fuscous, head, thorax, and superior wings green, vai'iegated 

 with black and a ruddy tint, lobes of the thorax with paler 

 marks, the edges black; superior wings with black spots on 

 the costa, and several very irregular strigse, and a black forked 

 line at the base, a large pale oblong spot on the disc, with the 

 outline of an oval upon it, and an ear-shaped one beyond it, 

 with an irregular pale stripe {)arallel to the posterior margin, 

 which has a serrated black line: inferior wings with a pale 

 line along the margin. 



This pretty and variable species is found the middle of April, 

 beginning of September, and in October, in most of the woods 

 round London ; also at Glanville's Wootton, and in the New 

 Forest by Mr. Dale ; Gibside, Newcastle, Capt. Blomer, &c. 

 The caterpillar feeds on the Oak. 



3. T. Chi Li7in.—Do7u v. 12.pl. 406. 



Hoary-gray, superior wings with numerous fuscous spots 

 on the costa, and waved and crenated strigae edged with black 

 and ochre, with a circular and an ear-shaped spot on the disc, 

 and a black X below them ; under wings white or fuscous, 

 with darker irregular spots and lines. 



Found from the middle of August to the middle of Sep- 

 tember, on old walls and rocks covered with Lichen, near 

 Edinburgh and Ambleside, by Mr. Dale and myself; in York- 

 shire and Derbyshire ; at Stonehenge by the Rev. G. T. lludd. 

 I found it at Linton in Devon ; also on Dartmoor ; and in 

 Anglesea by Mr. Donovan. A beautiful variety is taken by 

 Mr. Wailes near Newcastle, in which the ground of the su- 

 perior wings is ochreous-gray, bearing white spots ; the under 

 wings and the body are blackish fuscous. The caterpillar feeds 

 on the Columbine, (pi. 392.), Sonc/ms oleracms, and S. arvcnsis, 

 Lactuca sativa, Arctium Lapjm, and Salvia jvatc/isis. 



The Plant is Polygonum llydropipcr (Water Pepper).
