The food -plants of K. pisivora are Echium vulgare, Orchis, Rosa centifolia, 

 and yellow melilot {Melilotus officinalis), also Pisum saccharatum. in 

 Galicia. Odontothrips loti, Hal., is considered distinct from 0. ulicis, of 

 which it has been considered a synonym. The process of oviposition 

 by Taeniothrips primulae, Hal., on primroses is described. It has been 

 found on flowers of woodsage {Teucrium scorodonia) , primrose 

 {Primula vulgaris) and cowslip {Primula veris), and hibernating in moss. 

 Larvae bred from primroses in the spring probably reach the adult 

 stage and produce a second generation on other flowers in the same 

 year. 



Examples of Taeniothrips inconsequens, Uzel, have been com- 

 pared with T. pyri, Dan., and have been found to differ only in un- 

 important details and must be treated as synonomous, the former 

 name having priority. Both European and American examples feed 

 on Prnnus cerasus, but are not usually injurious in the former country. 

 This thrips is believed to have been imported into America from 

 Europe for the following reasons. Only females are found in America, 

 reproduction being entirely parthenogenetic, whereas both sexes occur 

 in Europe. Its rapid spread since it was first noticed in America 

 suggests the absence of natural enemies. The ease by which intro- 

 duction may be effected in the soil clinging to the roots of fruit stock 

 adds to the probability of this, as the insect spends 10 months of the 

 year in the soil in the larval and pupal stages without feeding. Only 

 ripe fruit, free from this thrips, is sent in the reverse direction. It also 

 has no near allies in America, whereas T. primulae, a closely allied 

 species, occurs in Europe. T. inconsequens occurs in England, Bohemia, 

 the United States and Canada. It may be found on laurel flowers 

 {Prunus lauro-cerasus), flowers of fruit trees, the young leaves of 

 horse chestnuts {Aesculus hippocastanum) and sycamore {Acer 

 platanoides), Prunus cerasus. Anemone nemorosa and Populus tremula. 



Thrips nigra, sp. n,, from the underside of leaves of elder {Sambucus 

 nigra) is described. Thrips {Bagnallia) calcarata, Uzel, on young leaves 

 of lime {Tilda vulgaris), T. nigropolosus, Uzel, on Avheat, and Bolaco- 

 thrips jordani, Uzel, are recorded for the first time in Britain. Hajjlo- 

 thrips flavitihia, sp. n., is described from specimens on hawthorn 

 {Crataegus oxyacantha).

 Naturalist, Edinburgh, no. 60, December 1916, pp. 301-302. 



The large larch sawfly, Lygaeonematus {Nematus) erichsoni, is re- 

 corded for the first time in Aberdeenshire. Owing to the damage it does 

 in England, this insect is included among those scheduled under the 

 Destructive Insects and Pests Order, and its presence must be reported 

 to the Board of Agriculture. Attelabus nitens. Scop, {curculionoides, 

 L.), Cryptorrhynchus lapathi, L., on willow, and Cryphalus abietis, 

 Ratz., on silver fir, are also recorded.
