sharp point at the head yellow, tipped with purplish - 

 brown; a purplish -brown spot on the shoulder; a 

 faintly deeper green line down the back ; a subdorsal 

 row of faint dusky spots ; the lateral ridge yellowish, 

 edged above with deeper green; the wing-cases and 

 their nervures softly marked with freckles ; a purplish 

 line down the belly. As the imago matures the 

 antenna-cases show red, and the wings and body 

 become yellowish. (J. H., 19, 9, 85.)

The sight of the caterpillars of this species feeding 

 on cabbages, and their unpleasant odour when plucked 

 off and crushed under foot, are among my very earliest 

 recollections; and I suppose the disgust which they

 much about them. And so, with the solitary exception 

 of a memorandum about a variety of the pupa, I have 

 no notes of an earlier date than the past summer (1885), 

 when I did what I could to atone for past neglect, and 

 braved the unpleasant smell of cabbages for weeks 

 continuously. I could get no butterflies of the first 

 flight, nor eggs from them ; but Mr. Bignell, at Ply-

 batches of youngsters, on July 8th and 14th; most 

 of these were already stung, and I got from them only 

 two pupae, luckily varieties, and I bred the butterflies 

 on August 13th and 16th, being of course examples 

 of the second flight. Females of this second flight 

 were captured by Mr. Jeffrey and myself, and laid eggs 

 on August 12th and 16th; the larvse hatched August 

 18th and 22nd, were full fed about September 10th, 

 and the last had become a pupa by September 15th. 

 Meanwhile Mr. Bignell found eggs and sent them to 

 me on September 1st, and again on September 29th,
