a dark tint, the tips of the antennas and feet becoming dull 

 black, the last four abdominal segments becoming shining 

 black, and the spiracles then become black : when this stago 

 of the coloration is reached, the head, thorax, wing-cases 

 and the dorsal surface of the first abdominal segment turn 

 darkish, and, running down the centre of the dorsal surface 

 of the abdomen, a series of dusky markings are noticeable ; 

 half an hour or so afterwards the colour of the head, thorax, 

 wing-cases and the back of the first abdominal segment 

 settle down to a dull black tone ; after the last-mentioned 

 change the abdominal segments (excepting the first and four 

 last) turn to a dull yellow tint ; as soon as this part of its 

 economy is accomplished the markings of the puparium have 

 arrived at their full development, and prevent our catching 

 the slightest glance of the gradual formation of the future 

 decorations of the imago. The imago, when fully developed, 

 pushes its way through the end of its cocoon, bursts open 

 its puparium, and so escapes, the empty puparium retaining 

 its decorative markings, but they are not so clearly defined 

 as when it was occupied by the pupa in its earlier stages. I 

 find that many of these insects die about the ninth day after 

 their emergence from the puparium, whilst others will live 

 for a period of nineteen or twenty days. — Charles Healy. 



Entomological Notes, Captures, Sfc. 



Notes OH the Lepidoptera of Orkney. — I send below a list 

 of the species that I have caught or reared. 



Pieris Brassicae. I have seen this species fijnng about the 

 moors, a mile or two from any cultivated ground. 



Chortobius Davus. Very common where it occurs. This 

 year it flew from June 30 to July 27. 



Pyrameis Atalanta. Rare generally, but this year the larvae 

 were to be found on almost every bunch of nettles. 



P. Cardui. Very uncertain. Fond of hill-sides. Middle 

 of June to end of August. 



Lycsena Alexis. Not very common. June to end of Sept. 



Macroglossa Stellatarum. Saw one in August, at flowers. 



Hepialus Humuli. Very common from middle of June to 

 middle of July. The larva seems to feed two or three years,
