The Genus _Calliphara_ contains a number of large bugs, elongate but broadly rounded in front, with the scutellum forming a complete convex shield over the back; 26 species are described ranging from China through the Malay Peninsula to Queensland. _Calliphara imperialis_ measures over ¾ of an inch in length, and has the whole of the dorsal surface, except the tip of the abdomen, bright shining red; the under surface, legs, and tip of abdomen are dark metallic green. _C. billiardierei_, about the same size, has the back and the under surface of the abdomen (except the tip) red; the head, thorax, legs and tip of abdomen deep metallic green with dull purple tints. _C. cruenta_ is a much smaller species, the thorax and basal half of the back red, shading into purple toward the tip. _C. nobilis_ has the head and thorax dark, with the dull red back spotted with black. All our species of this genus are found in the tropical scrubs of N. Queensland. _Cantao parentum_ measures over an inch in length, and is more elongate in form; it is of a uniform dull red tint, with the whole of the dorsal surface marked with small irregular black dots; the legs and under surface are black. It ranges along the Queensland coast. It has been reported to have attacked cherries in Southern Queensland. The Genus _Testrica_ contains several little brown bugs, short and broad, with the front of the thorax more or less produced into a spine, and the extremity of the abdomen broadly rounded. _Testrica bubala_ is not more than ⅙ of an inch in length, with the shoulders sharply spined; it is found upon the foliage of small gum trees. The sub-family CYDINAE contains a number of curious little black shining bugs that live on the ground and are often found hiding under stones. They are quick and active in their habits, and might easily be mistaken for small black beetles. _Geobia australis_, under ¼ of an inch in length, is of a uniform pitch-black colour, with the exposed tips of the elytra greyish-brown; it has spiny legs; the head is clothed with scattered hairs forming a fringe. _Adrissa_ atra is a much larger black bug; it has pitch-coloured elytra with brown tips. This common species is found about Sydney under stones and rubbish. In the PENTATOMINAE we have a large number of species. They are broadest across the base of the thorax, which is sometimes slightly angulate; the scutellum is large and angular, occupying the centre of the back but not covering the whole of the wing covers. _Notius depressus_ measures over ½ an inch in length, and is broad in proportion; the general colour is deep blue to purple, the sides of the head and thorax and ventral surface marked with yellow. It ranges from Tasmania to N.S. Wales.
