The typical Genus _Syntomis_, in which Hampson places all our species that were previously described under the Genus _Hydrusa_, comprises about 138 species, chiefly confined to Africa, Asia, the Malay Archipelago and Australia; 12 species are recorded from this country. They are all rather small moths of a general black or brown tint mottled with orange yellow or lighter brown. _Syntomis annulata_, about 1 inch across the outspread wings, has a very wide range from the Philippines through New Guinea and Australia, and naturally varies much in different localities; our variety is of a blackish tint, with six orange spots in the fore wings, and two more angular blotches on the hind ones; the abdomen is regularly banded with orange and black. _S. aperta_ measures 2 inches across the wings, which are of a brownish tint with large blotches of orange yellow occupying the greater portion of the surface, divided from each other by slender lines. It ranges from New Guinea and Queensland round to S. Australia, and has been captured out west about Bathurst, N.S.W. _Euchromia creusa_ is a very handsome form about 2 inches across the narrow fore wings, which are black with two large transparent divided spots forming a double row across them, and another very small one at the base: the hind pair have two similar blotches. The head, thorax, and basal portion of the abdomen are black, shot with metallic blue; the basal abdominal segments are crimson, finely barred with black. This beautiful moth has a wide range over the Malay Archipelago and the Pacific Islands, coming down to Thursday Island and North Queensland. Many of the foreign species in the larval state feed upon lichens or grass. Family 5. Burnet Moths. ZYGAENIDAE. These moths form an extensive family represented in most parts of the world; they are also day-flying moths, and some are very brilliant in colour. In England some of them are known as “Burnet Moths” and “Green Foresters.” They have long narrow wings, and the antennae thickened toward the middle. Most of our species belong to the Genus _Procris_, which are also very abundant in Southern Europe. They are small creatures measuring under 1 inch across the wings, and are of a general dark brown tint with greenish markings. _Hestiochora bicolor_ is a curious little moth remarkable for its bright colouration, which has a wonderful resemblance to one of our small parasitic wasps (_Braconidae_). The wings are clouded with black; the head and front of the thorax are red, the hind margin of the latter black; the abdomen black and white. Family 6. Hawk Moths. SPHINGIDAE.
