20 HAUSTELLATA. — LEPIDOPTERA. 



cinereous, obsoletely spotted with black ; abdomen whitish, spotted with black. 

 Female larger, deep cinereous, with the posterior margins much spotted with 

 brown. 



Var. /S. Bo. Minax. Hiibner '? — Of a deeper cinereous, with the abdomen black, 

 narrowly annulated with whitish, the thorax scarcely spotted. 



\'^ar. y. The thorax pale cinereous, with several very large black spots; the an- 

 terior wings with a very distinct transverse dusky fascia near the base, the un- 

 dulated strigsE towards the apex very strong, and each exterior areolet with 

 a broad longitudinal wedge-shaped brownish streak. 



Caterpillar at first black, with two short, rigid, appendages on the anterior seg- 

 ment; these disappear on the third moult, when the colour becomes green, 

 with one or two red spots ; and on the final moult, the upper surface becomes 

 bright green, the lower dusky-green, the humeral tubercle, and three spots on 

 the sides, bright red : it feeds on the willow, poplar, and saUow : is found 

 towards the end of summer : the pupa is enclosed in a very hard foUiculus, 

 composed of wood-dust and gluten. 



Far from uncommon in many parts of the country, especially in 

 marshy districts, during the latter end of May; it also appears in 

 some seasons a second time in August. " Near Amesbury, plen- 

 tifully." — Rev. G. T. Riidd. " Rarely near York, and Newcastle- 

 on-Tyne." — W. C. Hewitson, Esq. " Not uncommon in Cam- 

 bridgeshire." — Rev. L. Jenyns.

Bo. erminea. Hilhner. — Ce. erminea. Steph. Catal. No. 5966. 



Wings white, or whitish, anterior with several distinct black spots at the base, 

 followed by an irregular duplex undulated transverse striga, then two abbre- 

 viated streaks, the second arising from a costal spot, afterwards a lunate dis- 

 coidal spot, also arising from a costal spot ; behind the lunide are three strongly 

 dentate undulated transverse dusky strigae, with a row of fuscous spots ; the 

 hinder margin has also a row of somewhat cuneated black dots : the posterior 

 wings white in both sexes, with a discoidal lunule, and a marginal row of 

 black dots: the thorax is white, spotted with black, and the abdomen is pale, 

 with the base and apex immaculate, the intermediate part with large black 

 transverse spots. 



Caterpillar deep red, or reddish-brown, sprinkled on the back with white, with 

 a white lateral line : head large, with two black spots on the angles : when 

 young, nearly black : it feeds on the willow, poplar, and aspen : pupa pale 

 brown. 



This fine species has been taken at Birch-wood, and I believe in 

 other places near London.
