Monograph on Coccidae occurring in Britain.* — Robert Newstead 

 has completed the first volume of an important monograph on the 

 Coccidae which are found living in Britain. It deals with the sub- 

 family Diaspime, and includes a very valuable general introduction. 

 The author's illustrations are worthy of the series, and the text is the 

 outcome of many years of work well known for its thoroughness. 



Studies on Thysanura.f — F. Silvestri discusses, in the first place, 

 some of the characters of Projapyx, e.g. two glands which he has dis- 

 covered opening at the ends of the cerci. In the second place, he 

 describes 13 species of Japyx in his collection of which eight are new. 

 He then describes three new species of Nicoletia and one of Lepisma. 

 His communication ends with a brief account of South American 

 Thysanura, of which 29 species are now known. Of the ten genera, 

 Eutrichocampa and Trinemophora are probably characteristic of the 

 neotropical region. The genera Japyx, Campodea, Lepisma, Graseiella, 

 Machilis, and Nicoletia seem to be cosmopolitan ; Lepidocampa is also 

 represented in the Malay Archipelago, and Projapyx in East Africa. 



New Agricultural Ant from Texas.} — W. M. Wheeler describes 

 Pogonomyrmex imberbiculus sp. n., a small and inconspicuous form, of a 

 timid disposition, living under stones. It collects grass-seeds, which it 

 shells and treats in some singular manner, so that they have all 

 a glistening yellow colour like the animal itself. The myth that 

 Pogonomyrmex molifaciens sows, guards, and weeds the " ant-rice " 

 (Aristida oligantha) is regarded as a joke even by the Texan schoolboy. 

 The seeds which have sprouted too far to be fit for food are carried out, 

 but there is neither sowing nor weeding. The special ring of grass 

 about the nest is an unintentional and inconstant by-product of the 

 activities of the colony. A key to the species is appended. 



New ! Moravian Cave-Insect.§ — C. Absolon describes a new member 

 of the Collembola, Heteromurus hirsutus sp. n., from Moravian caves, 

 and discusses the other species of the interesting genus. 



Insects Injurious to Elm-Trees.|| — E. P. Felt describes the elm- 

 leaf beetle (Galerucella luteola), the bag or basket- worm (Thyridopteryx 

 ephemerseformis), the fall web-worm (Hyphantria cunea), the spiny 

 elm caterpillar (Euvanessa antiopa), the elm-borer (Saperda tridentataj, 

 the elm snout beetles (Magdalis), and the elm-bark louse (Gossyparia 

 ulmi). The coloured plates of these insects have unusual excellence. 



Honey of Bees.^f — H. Jimero has made a number of saccharometric 



and polarimetric observations on different kinds of honey from various 



parts of Spain. 



B. Myriopoda. 



Annectant Type of Chilopod.**— R. I. Pocock has had the pleasure 

 of receiving, through G. M. Thomson, of Dunedin, a consignment of
