CORRESPONDENCE,
Possibly flze readers of Psycn~ may LC inter- ested in 'an observation that I have recently made upon the food-habit6 of ?'fmjw, which, though it may ~ K Y C been noticed often, I do not find recorded in works at hand.
A few days since, finding TArips In species of Plilwothn'jia of wliicli I find no ilescriptiun) very abundant in ail the fruit blobsoins that I exam- ined, I was led to notice more partieulariy their method of work,and soon bfcaine convinced that they wore doing iniidi damage by preventing fertilization, as their injuries to tho tender style would cut off all uomraui'iiraitioii between the stigt11.i and the ovary. A careful examuintion of ft numbcr of unopened buds ~cveiiled the fact that in eighty per cent of them tho style had becu more or less injured by 'biting usid ptmctwing, while tile great number of Thjw present could lenve no doubt that thcy were the authors of the mischief. In thc~iinjorityof tl~ehdiicxami~~ed the styles seemed to be injured far more than any of theotherpartsof theblossom. Less than ten per cent of the bnds examined. vontaiucd larvae of Twtrividue. Of the remining hills a small perceutfigc contained no Titrips, perhaps because they were not qi~ite 90 far ndviincetl as the other buds. The Thrips probably enter the buds as soon aa they rail crowd in betwecu the uverlapping petals.
If the habits of Tin-ips are, in general, as dee- uribed above they have an economic as well as a wientific interest.

Mr. S: H. Scud-
(1er cxliiliiteda copy of Brongniart'e recent paper on fossil insects forming an Anrwxe to AndlGe's wwk on liymenopt~~a,iu which arc discussed the fossil hymmoptern of the periods since tlw has. He also showed a proof page of his own index to zoological genera, cxpkining the plan of the work. Mr. Smttldcr cnllcil attention to the very low prices at which the collections of coicoptwn of Mr. E: P. Austin nud of tlic late Mr. G: D. Smith were offered for mlc.
Mr. S: H. Scudder exhibited a drawing ilh. tmting the wing of a, heteroptcrous insect from carboniferous strata, of a period earlier tlinn :my in which hcteroptcra had ticen foimd. He also showed a very perfect carboniferous tiotikroacli. Mr. W: Trelcase rarriarked on tlic part that insects play in the pollination of New Zealand flowers, with reforc'nce to what lms been pub- lislicd on the subject, capdally to the roniinu- nicationa of Charles llarwin and G, Thornson. Mr. H. Ihyvrnrd spoke of the insccts~~wa&i- dae, d@cidue, Aphodivs and aoto~eclitlat-f ound in thesto~niieli of a kingfisher (Gee ulrgon} in Maine, last summer. Attention was drawn to the large proportion of cimitiidae.

Mr. S: H. Sfu&iw sliowecl a paper by Dr. Pritsch, of Frag, on a fossil opl~emcrid and on other fossil inserts, commenting on the paper and calling attention to the figures of crrtaccotis insects as king almost the flist inserts of tlus priod figured, and forming an important contti- bution to oar knox lmlgc of fossil insects. Mr. S: H. Scudder showrd figures of American tertiary ephemtridne from Florissaut, Col., show- ing that in the form of the body, in the stoutness of the lee, and in the respiratory apparatus thcy differ strikingly from living forms. Rtmnrks were also made on tho first fossil lepisinid, show- ing to what extent it differs from living Itpis- mids. Mr. Scudder also showed the first early pretcrtizry i~~swt found in Colorado, discovered near Fairplay.
