its perfect black ground on tlie body, which had become somewhat of 

 a brownish-green. 



The cocoon, found about three-quarters of an inch below the 

 surface of the earth, was of oblong shape, the diameters 11 lines by 8, 

 it was composed of earthy particles lightly held together with a few 

 threads, and though smooth inside, was without any perceptible lining 

 of silk. 



The pupa-skin was 7 lines long, very stout in proportion across 

 the thorax, the abdominal segments tapered to the rounded tip 

 furnished with two very fine straight and pointed spines, smooth in all 

 its ])arts ; of a dark warm brown colour and glossy.

New localities for Trioza crithmi, F. Low. — Having had occasionally a few 

 hours to call my own whilst in this neighbourhood, I paid some visits to the rocka 

 under Plymouth Hoe, and there I found that the samphire grew tolerably plentiful. 

 A very superficial examination of the plant revealed to me the fact that the above 

 named species was there in abundance in all its stages. From July until near the 

 end of August their numbers did not seem to diminish, although I took but few 

 merely for the sake of the locality. A little later on in the season, my friend, Mr. 

 Bignell and I made an excursion to a place called Wembury, and there also amongst 

 the cliffs we found it, but sparingly. On our way thither, and the road is a rough 

 one, we examined a large quantity of Artemisia ahsintJiiinn, growing on both sides 

 of a hedge on a farm on the Langdon Hall estate, in the hope of taking Apkalara 

 artemisicB, but there was not any sign of it, although the locality seemed a very 

 likely one. — John Scott, Devonport : \Qth November, 1SS2. 



[Mr. C. W. Dale informs me that he found Trioza crithmi this year in the Isle 

 of Portland.— J. W. D.] 



The early life of Psylla pyricola, Forst. — Up to the present time I have spent 

 over 140 days here, out of which there have not been more than 20 fine ones. 

 When the weather was fine and the time not otherwise occupied, a ramble was taken 

 with more than ordinary gusto, and being desirous of becoming acquainted with the 

 FsylUdm on pear trees, in the hope of getting Psylla pyri, Linn., if it was really to 

 be found in Britain, or at least, hero, and Mr. Parker, Manager of the Eoyal Hotel, 

 having very kindly given me an introduction to Mr. Brighton, head-gardener at 

 Mount Edgcumbe, I shortly afterwards waited upon that gentleman, who at once 

 gave me permission to wander about the grounds and gai'dens of the estate when- 

 ever I pleased. I accordingly paid several visits to the place between August and 

 October, but all my searching failed to lead to the capture of F. pyri. On some of 

 the pear trees, however, F. pyricola, Forst., actually swarmed, and having beaten a 

 few of the nymphs into my umbrella I began next to examine the leaves. On them 

 I soon discovered the ova laid irregularly along each side of and on the midrib 

 itself They are of a deep yellow colour, somewhat elongate, narrower or almost
