These interesting insects are extremely numerous in species,inhabiting the warmer districts of the earth, and reaching as farnorth as the middle of France. None, however, have been foundin this country. They are extremely variable in their forms. The Phasmidce are ordinarily termed spectres, leaf insects,walking-stick insects, from then- singular forms, remindingthe observer more of vegetable than animal Bacteria fragilis (New Holland). They are inhabitants of tropical climates, a very few species,of comparatively small size, being found in the south ofEurope, They delight in remaining stationary upon thebranches or twigs of plants, upon which they feed, thestructure of their legs being simply ambulatory. The ORTHOPTERA . 35/ student must consult the S}Tiopsis of Phasmida, of R. Gray, for fuller details and a notice of the variousspecies, distributed into many sub-genera. The family of the Crickets {Achetidce) comprises severalAvell-kno\ATi species of insects: the common house cricket{Acheta domestica), the field cricket {Acheta campestris), andthe mole cricket {Gryllotalpa vulgaris, Gryllus GryllotalpaLinn.) All these insects are eminently distinguished by thechirping, creaking kind of noise which they pro
