List of insects observed in Tresco, Scilly Isles, in August, 1878. — The following 

 list contains several names of insects which, so far as I am aware, have not yet been 

 recorded as occurring in the Scilly Isles ; but, for all that, it must be a vei-y meagre 

 list, for the weather was particularly unsuitable for finding insects. More or less rain 

 fell every day during the fortnight in which the observations were made, and, worse 

 than that, the most delicious mixture of brown sugar, treacle, and rum, not only 

 failed to attract]] the" commonest things, but seemed to positively drive all things 

 (except one A. ooulea) away from it. One bed of Senecio Jacobcea, well sugared, pro- 

 duced only the above named exception ; sugared tree .trunks — nothing ; whilst 

 another bed of Senecio Jacobcea showed wild sport with several species of Lepidoptera 

 during the same night. The blossom, which was sugared, was, I thought, in the 

 choicest spot in the island, viz., between the Abbey gardens and the lake, on an open 

 bit of heather, well sheltered and completely surrounded by trees, shrubs, and dense 

 beds of sallow, reeds, &c. The tree trunks which were sugared in vain were on the 

 other side of the gardens, near the attractive blossom. A huge lamp (of three 

 meteor burners), lighted on a marshy spot near the lake, failed to account for any- 

 thing but a few "micros." The abundance of larvae, excessive in proportion to the very 

 few images seen, and the decidedly omnivorous habits of almost all the larvae observed, 

 also tend to produce the impression in my mind that a worse August could hardly have 

 been chosen for the purpose, nor a worse fortnight in that month. I was taking 

 Triphana orbona just before I visited Scilly, and continued to see it in abundance 

 after that visit ended, but neither the type form nor the variety occurred there during 

 that visit. In the following October my usual mixture of sugar, treacle, and plenty 

 of rum proved very attractive, especially within a yard or two of the best lot of ivy 

 bloom I ever saw (but that was in Bedfordshire) . I feel sure that an entomologist 

 may find many insects in Tresco, even in August, that have not yet been recorded as 

 having occurred there. Deilephila euphorbicB did not reward my patience, though I 

 have reason to think its larva has been taken there, on the sea-spurge, by the present
