T.fuscum is no doubt attached to the Scotch fir. Some of these 

 trees, planted in the New Forest a good many years, have flourished 

 perfectly, and there are now some fine specimens amongst them. They 

 are already in possession of a considerable fauna, and I feel no doubt 

 that this will gradually increase. 



T.fuscum is, I believe, a rare species on the Continent ; indeed, 

 the only specimen in my own collection is a Swedish example from 

 the collection of Comte Dejean. T should be very glad to receive 

 information as to its habits, for I can myself find but little ; and we 

 have not yet been successful in obtaining another example of T. 

 fuscum. 



Tefropium luridum,the better known of the two European species 

 of the genus, is a common insect in the Alps, frequenting the stacks 

 of fir- wood piled in the forests to be removed as fuel for the winter. 

 I have met with it in elevated forests in the Alps on several occasions. 

 If my memory can be trusted, it is not the Scotch fir but a quite 

 different conifer that shelters it.

Notes on Eupitheciee. — When I was engacfed last year in working up the life 

 histories of the Eupithecice, Dr. LongstafF most kindly put himself to much trouble 

 to furnish me with larvse of the obscure western species — E. jasioneata, and to 

 provide food so long as it was required. A description of this larva has already 

 been published, and I need say little more about it, except perhaps again \o draw 

 attention to the curious way in which it conceals itself in the flower head of Jasione 

 montana by eating out a hollow space among the pedicels of the flowerets, in which 

 space or cave it lies securely doubled together, leaving little or no outward sign of 

 its presence. 



Now — iu June— the moths are emerging, possibly rather forced forward by 

 indoor warmth, and I cannot help being struck by their retiring disposition, and 

 great desire to avoid the light of day. On two occasions, on the boxes containing 

 the pupae being opened, a moth instead of allowing itself to be boxed or bottled, 

 has cleverly managed to slip by and to fly behind me, making instantly for the 

 darkest corner of the room, where, among books on the crowded shelves, it has con- 

 trived to conceal itself so closely that it could not be discovered. Naturally, I 

 expected it to come out and show itself at dusk, or after dark, and the greatest 

 source of anxiety was as to whether it would immolate itself in the gas flame. 

 But, no !, no such misfortune happened, nor did the moth in either case show itself 

 at all on the first night, but after remaining concealed another day, each specimen 

 appeared safely and in perfect condition, upon the window, on the second night 

 after its escape. Tliis circumstance, though happening to separate moths on 

 different occasions, would hardly be worthy of note, but that it, as I think, throws 

 light upon the habits of certain species of the Eupitheciir ; the determined retreat 

 of these specimens into the darkest corners being scarcely what is to be expected of
