22 HAUSTELLATA. — LEPIDOPTERA. 



colour : both sexes have a similarly coloured spot on the upper margin of the 

 posterior wings above. Beneath, all the wings are adorned with very broad 

 dusky nervures, resembUng those in var. X of Po. Napi, but varying in dif- 

 ferent specimens ; and the dilated nervure on the upper edge of the discoidal 

 cell is destitute of the insulated yellow spot, which every specimen of Po. 

 Napi that has passed under my examination possesses. 

 I have long had two specimens of this insect — which agree with 

 the figures cited above, and with the Bryonise of Wallner ; but Pe- 

 tiver's name having the priority, I have adopted it — the locality of 

 which I unfortunately forget ; but on the 4th of June last (1827) I 

 had the good fortune to capture a third specimen in Highgate 

 wood, agreeing precisely in its upper surface and in form — which 

 is of far greater importance — with the specimen from which figure 2 

 was drawn, but differing a trifle by having the nervures beneath 

 less dilated towards the tips of the wings. I have since taken other 

 specimens at Ripley, and Mr. Haworth has recently captured it in 

 Battersea Fields. There are also specimens in the British Museum. 

 B. With the terminal joint of the palpi shorter than the second : the anterior 

 wings distinctly rounded at the tip ; the posterior variegated beneath : the 

 pupa angulated, with an elongated acute process, or beak, in front : lateral 

 appendages wanting. (Mancipium.)

This rare British insect is white above : the female has the anterior wings black 

 at the tip, with four white spots ; towards the middle a large quadrangular 

 black patch, divided in the centre with a white line, and on the thinner 

 margin towards the tip is a round black spot : the posterior wings are edged 

 with black, the border being internally waved with white spots : beneath, the 

 anterior wings are nearly similar to the upper surface, but the apical and 

 central spots are greenish : the posterior wings are white, varied with yellowish 

 green ; the latter coloured part being finely irrorated with black. The male (of 

 which I have not seen an indigenous specimen) has not the black spot on the 

 thinner edge of the anterior wings above, and the posterior wings are imma- 

 cidate : beneath both sexes resemble each other : the body is whitish, with 

 the back black : the antennae are whitish, annulated with black. 



The caterpillar, according to the description of the continental entomologists, 

 is dull blue, edged with yellow and spotted with black : the head is clear 

 green, spotted with yellow and black. The chrysalis is greenish, or ash- 

 coloured, according to its age. The larva feeds upon various kinds of cab- 

 bages, on the Reseda lutea, and, from Hiibner's account, on the Thlaspi, 

 of which it eats the seeds.
