ORTIIOPTERA. 561 they have cast their pupal skin, probably copulate after they return from their flight to the nest, and then lose their wings, retaining only the basal stump. The males remain behind in the community, as according to the works of Smeatlinian, Lespes, Bates, etc., a king is said to remain always in the com- pany of the queen. After copulation the queen, which remains in the com- munity, swells up to an enormous size on account of the enlargement of her ovary, and begins to lay the eggs frequently in special places in the nest. They are at once carried away by the workers. Termes lucifugus Ross., South Europe. L., in tropical Africa, builds hills from 10 to 12 feet high. Calotermes flavicollis Fabr., South Europe.

They usually have tracheal gills on the thorax, and feed principally on the larvse of Epheme- rid(B. JYeniura nebitlosa L., Pcrla bicaudata L., P. (Pteronarcys) reticulata Burm., with tufted gills. Found in Siberia. Fam. Ephemeridae. May flies. Body slender, and soft-skinned, with hemispherical eyes, three ocelli and short setiform antennae.
