200 THE ENTOMOLOGIST. 



the latter a large mine in the roots of one plant seemed to point 

 to the presence of Sesia philanthiformis ; but this certainly 

 requires confirmation. 



In the Tineas, (Ecophora pseudospretella, Endoris fenestrella, 

 and P. cruciferarum were abundant ; the latter, no doubt by its 

 numbers, serving to conceal the presence of several other species. 

 Glyphypteryx cladiella was in tolerable numbers ; while one or two 

 species still await identification. 



A truly magnificent humble-bee was not rare.* 



A collector of Diptera and caddis-flies would reap a rare 

 harvest. 



Midges were most malevolent, choosing for their worst attacks 

 the time when one was boxing M. montanata from a sopping wet 

 and heavy net. 



From the above notes it will be seen that of Macro-Lepidoptera 

 five species — namely, Mamestra brassicce, Agrotis sujfusa, Triphcena 

 snbsequa, Apamea oculea, and Hadena oleracea — are new to the 

 Shetland Islands. How many more are new to Unst itself cannot 

 at present be ascertained, as Mr. Jenner Weir, in his notes in the 

 January number of the 'Entomologist' for the present year, has 

 unfortunately treated the islands as a whole, and has not given a 

 complete list of the species taken in Unst by Mr. McArthur last 

 year. It would appear from Mr. Jenner Weir's notes that twelve 

 species occurring in the mainland were not observed in Unst, but 

 which these twelve were we are not told. No notes of Mr. 

 McArthur's Micro-Lepidoptera from Unst, or of his second visit 

 to the mainland, have as yet been published. 



I cannot say that we were favoured by the weather. For the 

 first week we had, with one exception, either high winds or sea 

 fogs so dense that we constantly had to wring our nets out; 

 while on the 16th the weather completely broke up, and gales and 

 incessant rain stopped both day and night work, until our departure 

 on the 19th terminated one of the most enjoyable trips I have 

 ever had. 



The midsummer sunset and sunrise — and it is difficult to say 



* Mr. Briggs having submitted a specimen of this bee for identification, it 

 proves to be Bombus srnithianus, White (see Smith's Catalogue, 2nd edition, p. 202). 

 E. Saunders says of it in his Synopsis, — " This beautiful species has at present only 

 been found in the extreme north, and is recorded from Shetland and the Hebrides."
