underside : a deficiency greatly to be lamented, For it is 

 difficult to make out the different species of butterflies with- 

 out an examination of the undersides. For what I have de- 

 nominated Hesperia c6mma [in p. 227. No. 32.] the reader 

 will please to substitute Pamphihz ? Sylvanus. 



Now for my additions. I have, in p. 227., said that Hes- 

 peria malvae (Thymele alveolus Wood) was so scarce that I 

 never captured but one specimen. Knowing, however, by 

 this one specimen, that it was in my neighbourhood, I could 

 not account for its rarity; ami was, therefore, determined to 

 make diligent search for its haunts. In the most delightful 

 afternoon of May 18. 1833, I took a ramble through my 

 usual butterfly ground, in order to observe what was going 

 forward. I was unexpectedly gratified to find Hesperia Tages 

 and Melitse N « A'rtemis in great abundance. I also saw a fine 

 specimen of Sesia/uciformis ; and, as far as I could judge by 

 seeing a fly only on the wing, Thecla rubi. As this last was 

 a new discovery, I was continually on the look-out for it, but 

 unsuccessfully ; and of Hesperia Tages I only captured two 

 specimens before the 4th of June. On that day (June 4.) I 

 determined to take a walk over our mountain, to the valley 

 where I captured the Argynnes (Aglaitf, Adippe), in order to 

 look out for something new, and also for the purpose of ascer- 

 taining whether the meadow of the mountain produced Eleo- 

 charis acicularis or not. The day was beautifully fine, and 

 the mountain air invigorating ; the grass beneath my feet was 

 thickly interwoven with the beautifully white blossoms of Ga- 

 lium pusillum ; and the cottony tips of Eriophorum vagmatum 

 bent gracefully before the breeze. I am not perfectly certain 

 that I procured specimens of Ele6charis acicularis; but I 

 think I did. I thus spent the morning ; without fully accom- 

 plishing my wishes, but enjoying the circuitous flights of the 

 lapwing, which frequently led me considerably astray, in a 

 fruitless endeavour to discover its nest; or admiring the shuf- 

 fling of the grouse through the heath, in her anxious endea- 

 vours to lead me away from her location. This' passed the 

 morning, until I found myself by the side of an old ruin, at 

 the confluence of two mountain rills, the murmuring of whose 

 pellucid waters had often before ministered to the increase of my 

 enjoyment of the sunshine and the shade, as I have whiled away 

 an hour in listlessness after several hours' fagging after butter- 

 flies. I know of no place more delightful among the mountains 

 for lunching : J always make it such. The stream gurgles along 

 through its stony bottom in a continuous murmur, whilst its 

 precipitous banks are fringed and adorned with various spe-
